- This video is a fresh attempt to run my Data Center of Solar power. Three panels on the roof and the Allpowers R2500,, should have been able to cover my daily needs on days with lots of sun.
Unfortunately the R2500 does not at all like my UPS,, and or the other way around!!!
If you are way smarter than me,, do let me know in the comments,, what the heck it going on??

For 3$ a month, you get an extra weekly "What's UP" update video. Just for my Patrons. The Support I resave on patreon is all used on stuff to make interesting videos on RUclips.
My PlayHouse is a channel where i will show, what i am working on. I have this house, it is 168 Square Meters / 1808.3ft² and it is full, of half-finished projects.
I love working with heating, insulation, Servers, computers, Datacenter, green power, alternative energy, solar, wind and more. It all costs, but I'm trying to get the most out of my money, and my time.

Morton,
1) the server and UPS are an inductive load that is too heavy for the R2500 when the switch occurs (large spike) on the output of the R2500), this deforms the sinus produced by the R2500 causing the UPS and the R2500 to see a deformed sinus or bad power (causing error). Try a lighter load as a test first (only UPS, then with load, etc).
2) I don't know if the R2500 is programmed to switch automatically between solar and grid power if the battery gets too low, If you are trying to use the R2500 as a power wall, you should ask AllPowers if the Powerwall function is available or even hardware-supported by the device first.
3) Excellent video, I love it when you do stuff like this it's very relaxing, I hope to hear from you soon!
Thank You,, I have been wondering what would happen if I run a ,,, like 500W non-inductive load on the R2500 and then add the UPS,, and if that works,, remove the non-inductive load again.
The R2500 properly also outputs a horrible 230V/50Hz output, Those power banks are typically poorly build
I had a similar situation when trying a cheapo generator on my APC 5000 UPS. It to do with the sine wave. Inverters/generators that make PURE sinewave work with UPS's Quasi/Half sine wave dont work. Morton hope this helps

Hi @romanrm1
Thank You very much! glad you liked the video :-)
Thank you for watching! :-)
UPS whistle triggers my mind in a very peculiar way, like an 30 minutes timer.
I am not following you ??
I think the ups is trying to charge itself with a current over the allpowers limit per port, you might want to reduce this
the Allpowers does 2500W Max (Surged 4000W) and the UPS load was maybe 300W,,, I do not think the UPS would send 2200W to the batteries right away..
My guess, the UPS does not like the initial load / draw when switching over.
Try power these direct & not through the UPS, I bet that will work.
Yes something switch mode somthing somthing..
@@MyPlayHouse Can you delay them all powering on at once?
My UPS doesn't like the generator either when the generator is under higher loads. I bet that's the problem. We had tons of power cuts here and I ended up removing the UPS and putting voltage protectors in instead. This with my ATS between generator and grid, caused everything to work. This is mainly if we get notified about a power cut so I can fire up the generator, but still. It is a real pain to power a UPS from another UPS, which that allpower one is equivalent to really. Hopefully you'll get this one sorted. One other option was to have a filtering after the generator before the UPS that gets closer to a sine wave again.
I have the weird idea,, of maybe I need to put the R2500 under a little load,, like 100-300W light bulb,, to present the UPS with a better looking sine wave,, just an idea.
@@MyPlayHouse That may help. The joke is that the better UPS systems tend to be sensitive to this, whereas the cheaper ones just don't care. I have a voltage stabilizer here on some loads which uses a transformer. They tend to take the fairly jagged outputs from cheap inverters and smooth it a little. The best inverters are pure sine wave, but those are really expensive still and tend to not be in the kind of gear that at least I can afford :) Definitely interested to see how this works out, as at some point I will end up with solar and am likely to power my IT gear with that to reduce the 'never-ending electric use' for that a little. Good luck!
I will try again,, now that it is all set up :-)
great 👍 great I like it very much great 👀👍
Thanks for the visit
Either too much surge or the battery pack you're using isn't a true sine wave or something. I imagine those UPSes are designed to protect from voltage sag and too much electrical noise so they will throw a fit at those things.
Hi @HobkinBoi
Thank You very much! glad you liked the video :-)
Thank you for watching! :-)
Hi Morten, I think you answered your own question in the end, I'd assume the AllPowers is a high frequency inverter and the startup load is just too high for it.
It can do a surges of 4000W,, that should trip my breakers
if allpower outputs the same phase on each connector, you could try wiring live terminals together.
also you could make it so the automatic switch vould switch to ups if the power from all power disapears. And ups is connected to mains so if mains also disapeers then, emergency shutdown porbobly.
Hi @aljosamlinaric8705
Thank You very much! glad you liked the video :-)
Thank you for watching! :-)
As you mentioned @19:25 , relocate the ALLPOWER closer to the solar and this should fix your issue. I spent $400 on copper wire that could of been as simple as a $5 lamp extension cord due to the location of my power invertor in my car(I run a microwave oven from my trunk " Cookin' Ravioli in the trunk of a car w/Chef Mic-O-Wave
" lol).

@@MyPlayHouse I enjoy watching you do things around the home, it gives me a sense of accomplishment if I suggest fixes for things I myself don't do cause I'm here all day haha. Forgot to add: Use an plumbing torch to unsolder connections to cut down on connector cost, water flowing over the cable or a wet rag handy to cool the wire and crimp after helps. Soldering on blocks outside will leave cold-joints, and could cause problems later on
UPS may be requiring a sine wave power source, and Allpowers could be providing an approximated one (square wave), that's an often-seen reason for incompatibility. But then some computer PSUs would complain as well. Overall, it seems extraneous to also use the UPS in this scheme: the Allpowers is already an UPS as it has a battery. Seems a waste to run 2 UPSes in a chain, especially if that's putting an obstacle to the entire project.
This is one of the better sugestions,,,
get an outlet that is controlled by a wifi relay - then you can keep things more discrete and simple - use home assistant to automate. you may want to cut out grid completely and just get another solar gen/ups - do a follow up after you have experimented more, you may want to use heavier wire and put in another pvc pipe so as to get hepa pos pressure vent use solar powered fan in your attic during day and then at night you can let draft passively vent. #Shelly 1PM - WiFi AC/DC Relay Switch 16A
Hi @shephusted2714
Thank You very much! glad you liked the video :-)
Thank you for watching! :-)
i am using 2 delta pro's ( with an extra battery ) with 6x 425W panels and i can keep 600W load non stop.
That is a big load... I think mine is like half.. never got to see it,, as it did not work.
Hi Morten, what happens if you use the R2500 as input A of the ATS and the UPS as input B. Then connect the output of the ATS to your server? If the power of the R2500 is not considered ‘clean’ by the ATS, it probably will try to switch.
I did not get that fare,, as this part did not rally work...
The UPS might not lkle that there's no Earth/Ground from the AllPowers. I know my APC UPS is sensitive to that
Okay,, not sure how to ground it 😳
i'm powering my servers from solar. I generate around 2000W during day and it gives aroynd 10-12kwh a day
I am getting closer with my big setup,, 8.370KW
@@MyPlayHouse Nice! I don't have enough lifepo4 batteries to store that much :D
Although with newly aquired R730xd and couple Qnap NASes it could be useful :D
Most of the times a real UPS does not play well behind a inverter that does not produce a real sinus at its output..
That is also what I have found,, do you think a 100-300watt light bulb in parallel, would smoother that out a bit.
In rush current is to much for Allpowers.
I do not think so,, maybe too slow to react or something,,,
Just a thought can the Allpower not be your UPS and power switch? I was under the impression you can plug solar and AC into the solar generator (Allpower) and it will switch between solar and AC. Some solar generators you can set when it switches over e.g battery percentage. I would bypass the UPS and try this as you wont need to buy anything else if it works this is what I will be doing in a few months on my office / rack in the garden (just building it at the moment).
The R2500 does have the UPS funktion,, and I would trust it with my PC,, but the Server and Storage,, it needs to earn that trust :-)
@@MyPlayHouse I understand, maybe try it with a test machine / server first.
Keep the UPS in line. Oupes isnt known to put out clean energy so you want something in between stabilizing all of that. I got a setup like yours running with an oupes exodus 600 and a UPS from costco. My only real learning curve is learning some of the oupes models dont like (will break internal circuits) charging and powering things at the same time meaning they arent real solar generators. They are more emergency batteries that get charged and then sit on standby just in case.
Hi @bandwidthpiggy9378
Thank You very much! glad you liked the video :-)
Thank you for watching! :-)
do you have a outlet power meter, that you can see what the starting amps are for your ups?
I do not know what the UPS takes at start up,, but the Allpowers does 2500W Max (Surged 4000W) and the UPS load was maybe 300W,,, In my mind it should handle it..
@@MyPlayHouse what voltage is it using 120 or 240?
is there an amp rating on the ups? 2500w at 220v is only 10 amps, if the ups is pulling 15 continious then that would be 3300watts
it appears your ups is pulling too many amps for the rs2500, what if you use a smaller ups, to see if it will power a smaller ups and server?
I do not think that is it...
What is the wave form from the Allpower like?
I have not seen it :-/ so I do not know...
couple of things.
1. wiring from solar panel to the box needs to be as short as possible. dc voltage suffers greatly from voltage drop at higher amperage. realistically that looks like 6 or 8 ga, you should be using 4 or 2.
2. that battery box more than likely does not have the peak output to spin up more than say 8 enterprise hard drives ma-bye 12 2.5 laptop hdds. its drifting from the normal (120v 60hz in usa) set point and shutting down to prevent damage. as the load goes up the voltage drops and the freq can become unstable, and that is what it appears is going on here. either it cant handle the inrush current, or the freq. gets erratic and your ups sees it as a distorted input.
3. the solar input on your battery box is limited. some are as little as 400w.
as an example i have a smx2200 apc it can put out about 2kw or 2200va i converted it to run on a 15a plug but only after understanding that the max charge rate for the batteries was 430w. and my max load is 672w. i live in a old house that still has fuses so staying below about 1600w is mandatory. the inverter in the all powers is not clean/big enough. i would be curious to se a scope of the ac output under load, would answer alot of questions.
The Allpowers has a Capacity of 2016Wh (48V 42Ah) and can do 2500W Max (Surged 4000W)
There is plenty of power,, something else is going on.
I’d put my money on the up’s being to much on initial surge load for the power bank 🤔 I C rated the MCB for the radial circuit my UPS was on. It sometimes lifted the breaker on initial surge from the UPS turning on. I am a sparky btw.
The Allpowers does 2500W Max (Surged 4000W) and the load was maybe 300W,,, I do not know.
@@MyPlayHouse unsure by what value it actually peaks to but I’d be guessing to blame the transformer within the UPS. Transformers like 240v to 110v job site transformers are sometimes notorious for tripping the breaker on initial plug in and that’s with nothing plugged into the transformer for load.
possibly inrush current of the ups is too much load for the allpowers station, or allpower station has not clean sinewave output and ups does not like that. you need to either get smaller/different ups or different power station. Maybe power station can act as ups as it has battery, are the output not clean? maybe just use ups for grid if all power giving clean sinewave and it has battery?
he Allpowers does 2500W Max (Surged 4000W) and the UPS load was maybe 300W,,, I do not know.
Seems that it needs ground to be connected. What is UPS model you have?
This one : ruclips.net/video/c1x2O77f_6A/видео.html
There is a video naturally :-)
@@MyPlayHouse ok it's 1000VA so it can't overload this Allpowers charger. So it must be grounding wire connection.
Allpower ground missing.
Yes it is not grounded,,, you think that is it?
Does the manufacturers instructions for the MC4 connector recommend soldering?
I did not solder any of my mc4 connectors.
@@jstechsector3925 also the best, since the soldering gets hot and cold as the load goes high and low. So the solder will expand and retract, making the connection bad over time.
I am sure they do not,, I like it this way..
and I just wanted to make sure that I didn't have to open all the connectors again and solder them additionally 😉👍🏻
Hay morten, and guys I have 2x 655w solar panels I can’t use 😢 they are in London Uk though, not been connected or used anyone up for taking them off me ??
Wah 655W,, I would love them,, but London is far far away :-)
Never place a laser printer on a UPS ....
Well, I guess it's the same thing. It pulls too much.
I do not have my printer on a UPS :-)
I think it is not possible to power an ups with an ups (power bank).
Hard for me, to argue against that :-)
Maybe the poor power factor from UPS overloading the R2500.
Well pretty bad UPS not to take the power... :-/
your ups maybe complaining because the allpowers doesn't supply an earh ground and all the mains input's to your equipment will require a growing (earth) connection alpowers will supply an isolated output
Humm I do not think this is it,, but I have not thought of it..
lol

@My PlayHouse Hiuge power spike at the start-up... What else can be then that...
bad sine wave maybe..
I think the Powerbank doesn't output pure sine wave at the moment of initialisation. UPS are really sensitive to bad quality power-input.
Try to switch on the Powerbank-output before connecting the ATS-input.
I have the weird idea,, of maybe I need to put the R2500 under a little load,, like 100-300W light bulb,, to present the UPS with a better looking sine wave,, just an idea.
@@MyPlayHouse I'm pretty sure, the output has to be switched on before connecting the load to the powerbank. Every sine-inverter needs a little time to adjust the frequency and amplitude. About one full sine-wave or 1/50s (20ms). Good UPS switch to battery in less than 16ms, so they have to be very sensitive.
Hmm. With the UPS plugged into the AllPowers you're basically charging a UPS from another UPS. I'm not sure, but I don't think that would work. I remember in past trying to plug one UPS into another and it all just failed out. Maybe change everything around to sort of an A/B power type of setup? Connect the A side power supply of each server to the AllPowers, then the B side power supplies to the UPS. That way, if the AllPowers fails everything rolls over to the grid on B side with the UPS in the middle in case the grid power fails. Or, come to think of it what you could also do, if you prefer to keep both power supplies on each server on the same source: Connect output A of the ATS to the allpowers and output B of the ATS to the UPS while setting the preferred input ont he ATS to source A (allpowers). Leave the UPS to power itself off the grid, and the AllPowers to power itself off of grid / solar. From there, just connect both power supplies of each of your servers to the ATS. With that setup, if the allpowers fails the whole setup just rolls over to power B - which feeds off the grid with the UPS in between in case of a grid failure.
The A and B side on the ATS,, is the same,, you decide what is used for what. Grid or not grid...
