Sweet set up
Thank you. , I appreciate that.
I'm a bit jealous of your DIY solar system. That's an awful lot of panels.
I don’t use all at one time but have the option to bring online at any time. Also gives me flexibility to work on different arrays without shutting down inverters. Bought at $23-$40 each over the years. I live 30 minutes from the place that sells them. These new bifacial solar panels were the first full size panels I bought brand new. With the used solar panels they were so cheap I could over panels my arrays since they only put out 50-80 percent of stated power in watts and amps. Still will put out almost full voltage. I have a large piece of shaped lot of a 1/4 acre so I have room in the yard. No solar panels are on my roof of house. Hope you have a truly wonderful and extremely blessed 2024
I wanna see puppy.
Puppy is on vacation for 2 weeks.
In your experience, does the LF growatt do better with motor loads and lighting? Specifically, when it powers motor loads would some lighting flicker or pulse?
I have a EG4 6000xp and occasionally when our washing machine or one of the refrigerators start up some of our lighting pulses or flickers. I'm wondering if using a low frequency inverter like the growatt 12k you installed would solve that?
Every once and a while I will get a slight flicker of lights but I believe it is because my solar disconnects on inverter as it slightly goes over the 150 volt dv PV input. The 12kw low frequency inverter is rarely more than 50 percent load so no flicker except when what I stated above. If I start my 3 1/2 ton whole house heat pump, it might for a second or two flicker as it starts the large load but stops. So it still happens with 12 kw Growatt. Nit sure if you can add the Growatt transformer to better take that load flicker but for me it’s not a problem with an occasional flicker. Hope this helps. Hope you have a truly wonderful and extremely blessed 2024
@@diy-solar-guy Thanks for your reply. I'm looking to expand my system and will probably just add another 6000xp. I was just considering the growatt 12k, as it looks solid.
Thanks and God bless
@@kenthiergartner1506 the biggest draw back with 12 kw low frequency Growatt inverter is you can not expand like you can with the EG4 6000. I have 2 12kw for the reason. I also have 2 - EG4 3000 watt inverters in parallel to run mini splits, washer, heat pump dryer and such. But that 12kw Growatt can start my big heat pumps ( 3 1/2 ton, 4 ton and 12.7 ton heat pumps) with that large coil inside and able to surge to 36,000 watts to start those large loads.
Any recommendations for a way to get 240 volt solar in rv. Looking to upgrade my washer dryer and also upgrade ac to 240volts. Thanks
Depending on the room in your rv and how many solar panels you could mount and the amount of power needed in amps or watts used. Mainly the power needed to run washer dryer. I am using 2-EG4 3000 watt inverters in parallel to get split phase to run my 18,000 btu 230 volt mini split that uses up to 2500 watts, signaturesolar.com/eg4-3kw-off-grid-inverter-3000ehv-48/?ref=diysolarguy or EG4 6000 watt split phase inverter signaturesolar.com/eg4-6000xp-off-grid-inverter-split-phase/?ref=diysolarguy. You would need to call signature solar and ask them about both inverters stated above being able to start and run your appliances, will need info from appliances for watts and amps needed along with min circuit breaker for loads. There also have mobile solar off grid kits for rv's as well.signaturesolar.com/kits-bundles/complete-mobile-solar-kits/?ref=diysolarguy. I installed a 12,000 btu mini split in my 23 foor motor home that is 120 volt. I will be installing the EG4 3000 watt off grid inverter in my 23 foot motor home along with maybe 3-400 to 500 watt Bi-facial solar panels on roof or use 12-100 watt grape solar panels on portable ground array. have not decided yet. I can run my Electrolux heat pump dryer with my 2-EG4 off grid inverters in parralell and my full size Electrolux washing machine in my garage at the same time. Hope this helps. Hope you truly have a wonderful & extremely Blessed 2014.
You can have a qualified electrician make a splitter box, made for RV, park, electricity. Grabbing the one leg of the 30 amp and one leg of the 20 amp with twist lock attachment to give you 240v @20amp (not 30amp because other leg can’t carry it) Making a combiner box wire size will need to be different matching the 20 amp and 30 amp.
A journeyman electrician can do it with the proper gauge wire along with the proper breaker at the other end. It’s not a DIY.
But that would be the best solution that way when you show up to an RV park, you could just plug in your splitter box and run your washer and dryer.
Only Need to do laundry once a week or maybe every two weeks.
@@peckerpeter2078 I misunderstood your question. I know I have split phase in my motor home and could use my split phase inverter for solar with a 230 volt plug on output of inverter to plug into input of motor home shore power. But I rarely use more than 120 volts when camping. I have a hard time finding campsites with electrical hook ups. If I was boon docking for a couple of weeks, I would bring 5-400 to 500 watt bifacial solar panels and mount on EG4 ground mound solar array and be able to produce enough split phase power for all my needs. Just 5 solar panels I could bring inside motor home with solar array in storage area. Set up in 20-30 minutes at campsite. Hope you are able to accomplish what you want to do. Thanks for your input with all that great info in your response. Have a blessed day.
@@diy-solar-guy Not a problem brother I was just responding to the other guy wanting to use 240 V solar to run washer and dryer.
I was just stating with the time+ labor + money investment needed to do that. It would just be easier to go to an RV park with electrical hook ups, and use the combiner box they charging for electricity anyway.
Only a few hundred dollars to do the combiner box versus many many thousands for the solar panel and the 240 V split phase you would have to run plus batteries.
Motorhome solar shouldn’t need more than 120v, cost effective solution with quality materials, Weight should be in consideration as well, Motorhomes don’t get good mpg, the more weight you add the less mpg you’ll get.
Gonna be dependent if you’re a weekend Warrior or you’re doing full-time living…
How do you like those panels? Looking at adding 10/12 of those to my set up. Awesome price!
Have you realized any gains from the bifacial?
I was able to get 3200 watts the other day out of the 10 bifacials which is 4000 watt plus bifacial of 1000 watts. I had 24 used 250 watt poly panels and was only able to get 4500 watts total. So the new 10 bifacial panels gave me 80 percent of 400 watts per panels. The 24 used 250 watt poly panels only gave me 75 percent. I will be re arranging the panels in different configurations and testing. Right now I have all ten new bifacials in series. The 24 used poly panels are 4 in series then 6 set in parallel to keep input solar pv below 150 dc volts. I really like the fact that I can get 320 watts for one bifacial solar panel compared to 185 out of 1 used 250 watt poly panels. Solar panels are almost the same size. I will be buying more and replacing the used poly panels. Almost 2 times the amount of watts and amps input for almost same size solar panel. Will slowly replace. Thanks. Right now Signature solar has free shipping with orders over $2000. That save $250-$300 on freight.
@diy-solar-guy Are those the only 2 batteries you have, if so why don't you have more? That was very interesting to see in this video.
Thanks
I have 7-51.2 volt server rack batteries total split between 3 separate off grid solar systems. I am very happy with the EG4 LiFePO4 batteries. No problems at all. Charge and discharge very well and ah stay very close to each other in parallel.
@@diy-solar-guy That's awesome! You have a ton of knowledge about solar, and that's pretty cool to see
@@chrs1212 thank you. I have been playing with solar for 4 years almost everyday. Learned a lot from just trying different configurations and ideas. I don’t do a lot of videos showing how to connect all the components yet but will start doing those videos soon. It is so easy to connect all the components, the harder part is making sure your solar panels are configured properly to stay within parameters, but it really isn’t that hard. The parameters are on the side of the inverters and the batteries have their own set of parameters as well. But once you set up the first system, it easy after that. The new solar panels are 2 times as efficient as the solar panels from 5 years ago. Thanks for your comment, I appreciate it.
How many panels total do you have set up making power?
If I bring them all online, 10,000 watts on 1 Growatt 12kw inverter, 7,500 watts on another Growatt 12kw inverter, 4,000 to 5000 watt bifacial gain on 1 EG4 3,000 watt inverter and 4,000 watts on the other EG4 3000 watt inverter for a total of 26,500 watts. But it seems those used poly solar panels are only giving me around 112 watts -180 watts per solar panel as where the New 400 watt bifacial with up to 500 watt gain are giving me almost 400 watts per solar panel.
Can you run an air conditioner off of what u have now ?
I run a 18,000 bru mini split in garage, my 3 1/2 ton upstairs whole house heat pump, my 4 ton downstairs whole house heat pump along with my pool pump, 17,000 btu pool heater, 3- chest freezers and a fridge/freezer combo all at the same time during the day with only solar power. I run my 3 1/2 ton upstairs whole house heat pump overnight with EG4 battery bank as well. I spend $0 on heating and cooling my 2450 square foot house, garage and along with $0 on pool pump running 24 hours a day and heating and cooling pool water annually. I can also run my 7500 watt 230 volt 127,000 btu pool heat pump pool heater on solar during the day. I could run a 12,000 btu, 120 volt mini spli with just 3-400 watt to 500 watt Bifacial solar panels and a 24 volt off grid inverter with a 24 volt AGM battery bank during the day to run air condition up to 600 square feet of living space or probable replacing 2-12 volt AGM batteries in series or a 24 volt AGM battery with 2-EG4 24 volt LiFePO4 200ah batteries in parallel 24 hours a day. Very easy to do. I run 48 volt inverter solar power systems with the 51.2 volt EG4 LiFePO4 battery banks. In order to run my whole house heat pumps and 127,000 pool heater, I had to use a 12kw GRowatt off grid low frequency inverter, a soft start on each individual heat pump and at least 2-51.2 volt EG4 LiFePO4 batteries in parallel. I purchased all of these components from Signature solar. Click on links in description of video to find. I have videos on how I did this and feel free to ask questions as well. Hope this helps and hope you have a truly wonderful and extremely blessed 2024.

Thank you for the information!
@@Terrathrax you are so welcome
Now you just need to get rid of those low budget high frequency, transformerless inverters before they fail and take your AC appliances with with them. High frequency inverters lack a very critical component. That critical component is an iron core, copper wound output transformer. High frequency, transformerless inverters do not provide any galvanic isolation between its DC boost stage circuitry and their AC output which can allow high amperage DC current to pass through to your AC appliances and damage them. All it would take is for the inverter's control circuitry to fail and these high frequency inverters can send dangerous, high voltage, high amperage DC current straight to your connected AC loads which will not only damage most AC appliances but can also set those AC appliances on fire.
Thank you so much for your input. I have 2-12kw Growatt low frequency inverters that weigh 186 lbs each.
@@diy-solar-guy Those are awesome inverters.
@quickquote1568 they can run anything I have in my house or garage or yard. Excellent surge at 36,000 watts. I love having 2 of them. Bought refurbished. No problems at all. They have a few refurbished left. Follow links in description if interested.
@@diy-solar-guy I wasn't talking about your Growatt, low frequency transformer based inverters. Your Growats are excellent inverters, I was talking about getting rid of those "low budget high frequency, transformerless inverters".
I know you were talking about the Mpp high frequency inverters. I actually really like the new EG4 3000 watt high frequency inverters I have connected in parallel to run my 230 volt loads that don’t have large inrush amp at start up. 500 volt dc PV input. 80 amp output. 5000 watt PV input. Just got a few months ago and very happy with the way they run.
