you have to use a 150a dc breaker for the battery. it's on the side specification label on the inverter.
Hi Nick, I’m looking at putting one in my shed for yo run a small AC and a some tools. Just wanted to know how your inverter has faired with time and use. Thank you for the upload, I’m new at this and it’s helped us get a better look at how well these all in one systems function.
You would need more panel's and more batteries for airconditioning you may have to work out some calculations on power consumption on your appliances.
Thanks Mister, great video 😎👍🏻
how does tha pwm charge holding up are you gettting good power out of it
can you use this without battery, lithium battery with bms sometimes, cut off if already full charged. so i assume somehow inverter will detect no battery, so that's why, still it can works without battery?
Hello and thank you for a good video, I am about to buy a new inverter and would like one that can go directly to my grid in the house, I would also like it to have batteries on it so that it could help when there is no sun and for example at night, they wrote that this model can do it, but that's not what I see with you, you have a few sockets in the garage and what I'd like is the entire phase it's on, do you know which model can do it?
I'll have 425 amp hours of batteries next Saturday...I think that'll be about right for the amp draw it takes to run my oven..I've got 340 amp hours now and it's almost enough lol ...probably be better when the rain goes away too but like you say there needs to be some amount of reserve because I might want a pizza when the suns not out...I think I'm just getting enough batteries now maybe. I can run small loads for days but a 1500 watt load it wants to drop voltage gradually which I hope the 2 more will kind of fix...I started with 2 in November and I have 8 now so I'm guessing I need 10...at least that's a good reason to get 2 more panels to charge them with...I guess that'll be May's project....I think at some point it all starts to work right...if I get to run my little AC some this year for free that'll be pretty cool ..I hardly used it last year but it'll be free now...lol
hello, what would you recomend as my bulk voltage setting on my inverter, i have a 24v100H lithium battery with a charge voltage of 25v and a discharge cut off voltage of 16.5v...... cant figure how to set the bulk charge voltage in my 3kva inverter
Hi
I have the same inverter , but noticed that the inverter is getting very hot ? Also going off after short stints now
Hello! I am new to this stuff and I has recently purchased a 3KVA 24 VDC inverter. I charge this with 4 solar panels and this seems to work great. Unfortunately, I have a problem when trying to charge the batteries using my generator!!! I am on a 240/50 HZ system here in France and ...NUMBER ONE: I get input/output readings of 260/270!! (It is like the batteries are actually ADDING to the input/output!!) NUMBER TWO: The batteries do not actually charge...in fact....using the generator in the circuit seems to drive the batteries down to the low voltage cutoff and the inverter then shuts off. Any suggestions/opinions regarding setpoints and/or how to program this inverter properly would be greatly appreciated. Best regards, Anton
I'm not sure why you have these problems, but there is a video on my channel with some programming
Hi I’m looking at purchasing one of these inverters. But I need to to control when it charges the batteries, as in the uk we have cheap rate electricity at nights. Is this possible
Неплохо все собрано, аккуратно :)
How many panels did you use?
Very great idea ,
Bonjour est-ce que je peux utiliser cette onduleur pour injecter en autoconsommation dans le circuit 220 volts existant de la maison et en profiter aussi pour pouvoir charger des batteries ?
got one like these,even when bypass mode,the fan is nit stopping,even when battery is fully charged,pls assist
Ahoj, dá se nějak ovlivnit otáčky ventilátoru? Hodně to hučí.
I take it all the household appliances run on 230 and Europe ??
Hi mate Can you put a 48v system on that particular inverter ?
Does anyone know someone who has hooked up an oscilloscope to the output on a inverter. I would like to see the sinuswave. I know how it's look like on an inverter to a motor, but has never seen it on a inverter to the network. Does anyon never had problems with emc.
Hi Nick, and thanks for the video.
I own an easun mppr 2.2 kw inverter but I have a problem. I change the value of "voltage point back to utility..." (program 12) and after 10-20 min the value returns to default.
What could be the problem?
I can't find an official Easun support page ?!
great system ;)
What is the maximum solar wattage and voltage I saw you mentioned 4 x 300 watt panels the e bay site gives no solar input ratings I am putting 10 x 190 watt panels on a bus conversion
80 volts dc max pv array open circuit and operating voltage range 30 to 32v
the manual on page 9 has the info when i get a chance i will post
Hi, do you know if this unit is capable of charging a battery bank with the inverter switched off? Thanks in advance!
hello bro , can you switch from 230V 50hz to 230V 60hz ? is it better in Energy conserving and better performance?
Why is it only charging lifepo4 to 27 volts? as far as I can tell, everything is set to a full 29.2 charge ,which is also the full charge setting on the Battery pack's BMS..
You need a 100amp fuse. Between the battery and inverter. If the inverter is 2000watts. Then 2000÷24volt battery=100 If. 3000watts inverter. Divide it by the battery volt. 3000÷24volt battery=125
why?
Nick you battery voltage appears very low. Fully charged the voltage should be if using AGM battery's around 28.8 volts. Each battery appears around 100amp hours so you have 2 battery,s in series and 2 banks in parallel. So that 28.8 volts is 200amp hours. Regarding DC fuse between the battery and inverter. If you want to draw the whole 3kw from the inverter you will need a 125 amp fuse. Your programming is not correctly set. The MPP inverter are a very nice product once correctly fused and programmed correctly.
Thanks for you comments I did upgrade the fuse to 100amp and in my other videos I have shown program, feel free to check it out and comment I am also learning as I go
I have the same inverter, when i hook 24v battery to it, it shuts back off. It stays on about 5 seconds.
Looks great, thanks for posting. One question please. how big are your batteries? I gues they are 12V, 2 in series and 2 in parallel connected.
Batteries are 100ah connected to make 24 volts
@@fixingstuffwithnick7679 one more question please, what are DC input data, how much you get froma panels V and A? What is max?
Would appreciate for an answer. What would happen if sun goes down and batteries goes low. Will the inverter switch to Grid fast enought so my computer doesn't turn off?
If set correctly for use with a computer, it takes only 10ms switching over time. It depends on the computer load + all the extras connected to it as to if it would make a difference. It switches fine on mine but then it's only using a 35w CPU
@@dtvking Thank you for the asnwer! I think I give this system a go then. If I get any shut-downs from my computer or TV. Then I save electricity on my home heaters anyway.
Does the ac input allow u to charge up ur batteries and also does these units automatically switch to ac when ur batteries are low or your load is to much ?
Sorry for the late reply, yes to both questions
is this unit for off grid use only as i cant see a ct clamp that goes on the mains to stop exporting to grid i thought it was going to be like a grid tie inverter that powers the main wiring in the house and use is power from the batteries
NOT A GRID TIE. These are an UPS, INVERTER/ CHARGER, WITH A BUILT IN SOLAR CHARGE CONTROLLER ALSO.Has separate AC IN AND OUT, AND solar input. also has connection to turn a generator on,if there is no house power or solar power or charged batteries. all in one . uses and charges batteries. it's the coolest thing going . this model is still only 300 bucks. BUT. it is said to be only for lead acid batteries, but I've been using lifepo4 for years with no problems. the voltage requirments are the same. These only have PWM solar charge controller, which is no big deal with only 6 panels in good sun. But you can also, or instead, use any other MPPT solar charge controller to charge the batteries, if you want.
Hi Nick how are you doing? So I recently purchased the exact same inverter but I have some issues with it so I'll try my best to explain. So I live in an apartment and needed an inverter to power on my home appliances whenever we get power cuts. The inverter is connected directly to the grid panel that controls all the power in my apartment. What we tried first was connecting the AC input to the main fuse/switch of the grid and the AC output was connected to a separate fuse in the grid panel that was not in use. So while the main power/primary source was on, the inverter was charging and once it was full, I noticed the red fault light blinking. One day the power went out and the inverter showed an error 5 code. The system was unable to switch over towards the inverter in order to provide power to the apartment. So then once the power came back, I switched the inverter back, it went back to charging and the fault started flashing yet again. For some reason, when the power goes off naturally, it isn't switching over to the inverter so that the inverter can provide power to the grid. The only time when it does work is when we manually shut off the grid entirely and once we turn on the grid manually, the inverter switch over to the main power supplied by the grid and starts charging again. I also have to mention that I did configure anything in the programming so maybe that could be the issue but what are your thoughts on my situation? Hope to hear back from you. Thank you!
The system is not designed to connect to grid it should be stand alone .I would recommend seperate power outlets
Also there is a video on my channel showing off grid program
What i cont understand is what AC in is.. I just want AC out to my grid? Is AC in for backup? is this not an grid tie inverter?
This is not for feeding back to grid only off grid or used with grid for low power back up
my solar panels are not recognized (24v) and even the batteries are not. does anyone have a factory setting or a standard gel battery setting?
Wont accept battery 24v.Just turn off braker.Any advice?
Hi I got hybrid solar inverter 3200VA THE PROBLEM INVERTER DOWN FAN GOING ON AND OFF CAN I HAVE REASON
We need help with opti solar inverter installation
can this inverter put current back into the grid or is the output only meant for offgrid usage?
Off grid or supplement grid power used. It doesn't feed to grid
Can you draw current from the batteries and charge them simultaneously?
if you have more solar than load then yes.
(the solar never stops unless its dark and the invert doesn't stop unless low battery or fault)
Do you have user manual for this inverter sir?
Your solar input voltage seems a bit low. You need ~30V to 32V for a pwm to operate. The battery cables are on the small side. I would go for 35mm2 and a 125Amp fuse.
I have put in a 100amp fuse and the system for my shed/ workshop has been fine so far
Also I have put in heavier cables from unit to battery
3kw maximum output inverter will draw 3000/24 giving 125amps. The problem may come when batteries at 23.6v. The amps would be 3000/23.6 giving 127amps. You should considered 130+ amps. Depends on the length of time below 24v..
Hi mate, if you have a load of 800watts does the inverter gives 800w from either batteries or grid or it can give you for example 500w from battery and the rest from grid or vice versa
800 W would be coming from batteries. I do not have enough solar panels to run 800 watts constantly. But the system is still working and would be ok for up to 2000 watts . My system vis in my workshop for my tools and lights.
How good are these units it seems like an aftermarket of the Mpp solar inverters I was thinking bout buying me one but I really would like to know are they any good ?
Been great no issues so far
@@fixingstuffwithnick7679 oh that's great to hear
Do these hybrid devices also feed into the grid like a grid tie? when the batteries are full?
no there only plugged into grid for back up when the batteries are at low charge, mine never goes back to grid for power as my loads are not high .this system does not require grid power to work only as a back up option
@@fixingstuffwithnick7679 Thats sad. Can I also set that only a maximum value of watts is drawn from the batteries, and the rest is then drawn in parallel from the grid if I need more? can you make a screenshot what opions and parameters youre able to set up on computer with the data cable please?
That thing costs a lot of money for me, it should also be able to meet my expectations ^^
@@Bergwacht hi thanks for the question, what you can set is the lowest battery voltage that you want you batteries to go back to before it swaps to grid
oh Yes One question if you tested it ..... What happens with you're ac output, if no ac input is connected and at the same time you're battery's can not keep up with the load. Example: 400W output and battery's are almost dead? I had a very bad experience with this case since my inverter went unstable and has blow up some electronics causing fire ...... (almost lost my photo studio .....)
I can imagine they solved this problem with a relay when AC input is connected to bypass..... but without AC input I hope they did a good job shutting down the inverter before it gets unstable........
Hey good question it's programmed to go to grid at 22v ,if there's no grid you have no Power
@@fixingstuffwithnick7679 ok i understand this but what is the inverter doing at the last moment when the battery's are giving up and there is no AC input...... how is you're AC output reacting at the last moment. Can I trust connecting my laptop on it? Is it first becoming unstable or does he just shut down the 24O AC output? many thanks for you're reaction
@@LucMaes-123e-learning good question i will do that one day but i haven't as yet i have a reliable grid power available and the only time i have seen it go to grid is when the load was to much for the unit , at this point i have noticed a split second flicker in the lighting with a smooth transition to the grid ,the approx 10 mins later a smooth transition back to batteries and panels. if you didn't have the luxury of grid power as a back up you could purchase a generator with a battery starter(key start) and use the terminals off the unit to key start the generator . i guess the best thing to do is work out all your loads the average sunlight available and adequate battery storage for you. that is the difficult thing you have to do.In my case its for some lighting and on occasion some power tools a small fridge and charging of my tool batteries and e bike. for me the system never goes back to grid unless my load is over 2kw in a burst . this system is small but for my shed its perfect .
hey mate I'm looking for a 24v like the one you use, would you recommend the unit? Thanks Dan
Still going strong no problem with unit
Hello! How many KW of Panels can you install Maxim on this regulator?
Don't buy I've got one rated at 5kw but it gives 5kw when on grid mode.
When on batteries and grid or pv and the bateries hardly supply 3kw, the even when supplied 4.5kw from panels only
@@robertoleszek8361 That's normal for PWM if you want a good solar charge controller you'll want a separate mppt. I would only use the built in one for strings that are paired 12v for for this.
(4x 100w in 2x2 or something) (36v panels will not work well like this without mppt)
in my system i have 3 different charge mppt controllers with my 300w panel strings and only use the pwm for a few cheap 150w panels
Y my display stays off n faulty light stays on
30A x 24V = 720W. anything over 720w using batteries will trip the fuse. bad... you need a 100A fuse (2400W)
yes i have done that thanks
can this unit work with x 4 deep ( wired in series 48v ) cycle battery? 200a fuse?

Hi Nick. Can you run a refrigerator off this system. If so how many Acid batteries would I need and what size solar panels. I have a new medium size Samsung LG refrigerator. Refrigerator watts 120 power in put 160 defrosting power input. Voltage 230.
160 watt output sorry
160 watts defrosting output sorry again Nick. Your help would be great live in the Philippines and in the mountains have just about everything off the grid but my refrigerator. No need for aircon were I live.
@@EL-iu2tp Hi, you can count Amp/h*24v system example. you got 200Amh system for 24 volt, 200*24= 4800 watts, then 4800 watt / 160watts of your fridge is = 30h in use, remember tho that fridge is not always on 160 watt use its only then it compressor is on so its like 45% of the time off. And one other important thing led acid batteris is working between 50-100% and lithium 5%-100%. but lithium is better is you know what you are doing beacose of fire broblems.
I have a similar inverter charger, sadly for some Reason I can’t make it charge the batteries with a gas generator ac, the only thing I see in the screen of the inverter is a ac logo blinking sometimes but not charging batteries at all. And I changed the charger priorities through all the options without any luck :(, someone knows the reason?
Hmm. It should not do that blinking on stable AC power . Maybe your generator AVR is set to a different freq?
I tested also one at my neighbour, it does the same , but if you turn off the power button will charge the baterry , unfortunatly ours has charged the baterry for about 30 seconds then it maked a white smoke and we think the charger module from utility input is fried but we will investigate further … 🤕

Hi
I have the same inverter, and it says on the User Manual: 'before connecting to AC input power source, please install a separate AC breaker between inverter and AC input power source'. However, fot what I can see in your video, you are using (half) an extension cord which connects from the inverter directly into a wall socket. Did you research this? I have seen this system on you tube with the same extension cord into wall socket configuration, so I am not sure why 'eveybody' seems to be ignoring the manual!?
Also, quoting the manual again: this inverter/charger should be connected to a permanent grounded wiring system'. I cannot see this clearly in your video. How did you go about it?
Thanks in advance!
Hi. I have the exact same question as yourself. Manual says it needs a seperate breaker for the AC input. Perhaps they mean you need a breaker if your plug does not have a fuse, or if your inverter is wired directly to your homes consumer fuse box?
@@klausschwab4019 This goes deeper than I thought. Reality is that most people on you tube either don't really know what they are doing, or they are taking a bit of a risk. At the moment, in my situation, I am not going to add AC input because it seems to be too much hassle to do it safely (and I don't understand the issues fully, anyway). 'All in one' inverters with AC input are a new thing, and even local electricians don't know how to deal with it. Main issue seems to be the earthing/grounding arrangement.
Best resource I have found is Rolland W's channel and specifically the playlist about earthing inverters. I have also written some comments there that may help you.

@@headphonekiller5 Thanks for the reply. I think with the small 1kv version I have it already has a fused plug. Where it asks you to add a breaker in the manual Im pretty sure its referring to the plugless versions that therefore dont have fuses and thus you need to wire it to your consumer box and add a 10A breaker. Thats what I think it means anyway. My version comes with a plug with a 13A fuse, this is obviously sufficient.
How do you charge your battery without AC input? You cant really use this device for its intended purpose without AC input?
@@klausschwab4019 Sure, I may be overcomplicating things, and you could be right. My system didn't come with a fused plug, but it'd be easy for me to attach it myself. However, for what I have read, this is not good practice (for my system anyway).
I'll be charging the batteries with the solar panels of course!
Let me know how it goes with the AC input plug, or if you find a definitive answer at some point please.
@@headphonekiller5 I am not an electrician but I have some experience with electrical work, fitting breakers, fitting electrical showers etc. under supervision from a qualified electrician. I always make sure I know exactly what I am doing before I do anything electrical but I am not qualified to give advice, but this is what I think the manual is asking for, and people should only use this as a guide to find the right answers elsewhere, I wouldnt trust some idiot in a youtube comments section.
My system is a smaller system, the inverter is only the 1KV system which comes with a plug you can plug directly into a normal plug socket, the plug is obviously fused and so will blow if the unit tries to draw more than 13 amps.
I believe the larger inverters do not come with a plug which I can only assume is because the power is larger and so they need to be wired properly with the correct gauge of wire to your consumer box with a proper breaker switch, which would make it much safer than the plugged system, but of course the 1KV system doesnt need to be that safe because it is lower power, this is my lamens understanding of it.
Bear in mind Im an idiot and I briefly considered splitting the plug wire in half and putting the battery breaker in between the plug socket and the inverter, thats how confused I was, this wouldnt have been dangerous as long as the breaker was never touched, ofc its ridiculous and hence why I didnt do it, but thats what it seemed to ask in the manual lol.

No sorry the system is in a shed/garage and is purely for using lighting small fridge tools etc. Still going strong with no issues
Hey, Okayyyy i'm convinced to buy one. Bye the way about you're fuses .....
It's P = U x I so 2kW should be like 2000 / 240 = 8A fuse for AC output. 2000 / 24 = 80 A fuse for de battery

Hi Nick, I bought the same system but I am having some operation problem with it. Can you help me?
maybe i can what is your problem
ruclips.net/video/d3acQlTZnS4/видео.html&ab_channel=DIYSolarPowerwithWillProwse
watch some of these videos it may help as well
I have read through the manual from cover to cover but I couldn't find anything on the voltage when the system restart after it shutdown when the voltage is low. I observed that even when the battery voltage has risen to 26V the inverter is still didn't start. I have to manually start it by switching off and on the main switch. Another problem is when I hookup the generator it keep flipping the output between the battery and the generator. Everytime it flip you can notice the switching over from the generator and the battery. Very annoying. I don't know why it cannot power the load by the generator alone. Another observations, it's not charging the battery.
Saw the video, again it only mentioned when the system cut off but didn't say how or when it restart.
Ok I bought this solar inverter and i would be good to know the following for people who are thinking to do so as well.
- The battery connections at the bottom of the inverter are very close and can cause fire when having a short circuit.
- But most important ..... don't let this inverter work with AC backup since it can not guaranty a solid 230-240 Volt when the battery goes under 21V. At that moment the inverter goes on en off every second witch can cause damage at you're devices, certainly when the voltage starts to swing between 190V till 210V. At that moment the inverter should just stop with working. (I had fire once with a light dimmer who exploded in that situation)
- You should have extra fuses, diff switch and over voltage checking system at the output of this inverter.
If you have a AC backup there seems no problem since the inverter will connect to AC when the battery is low, and it will wait till the battery is fully charged again. A extra security to cut off the output with manual reset, when the battery is lower than 22 V would give me more peace of mind.
it looks as a good inverter and does what it should do, but be aware this is not a plug and play device.
Hope you like this positive feedback. Cheers
