  • I am considering buying a 2000 watt inverter. Looking at Renogy, but I don't find that Will has reviewed this one - Hoping for feedback on my plan, which is to install 2, 100 ah SOK batteries in my truck camper with the Renogy combined DC-DC/MPPT charger - and this inverter. My max inverter load will be my Microwave which is 900 Watts withe 1350 rated input power. Any advice?

    I am just finishing up my first 12-volt system. I went with Renogy 2k watt inverter. Got it through Home Depot with a 10 percent military discount. It has done very well. I am no expert, more like newby, but I have one and it will run a 1500-watt space heater and two deep freezers no problem. I will probably get a Samlex Inverter next.

    Does this look right? Will has the 250 amp fuse right off the battery before the busbar. Ty all new to me, wills book also says a 200 amp fuse with 2000 watt inverter. Thanks again

    I have a problem I'm hoping someone can point me in the right direction. I have six identical panels that I'm wiring in series-parallel. When I have 4 hooked I am producing close to 900 watts in good sun but when I hook the other two the watts drops down to 570 watts. When I just try the two alone I'm producing around 400 watts. I don't understand how adding panels is reducing power??

    Got it figured out. I was wiring 3 separate series of two panels instead of 2 series of 3 panels.

    Mmm but shouldn't wiring in 3 series strings still produce the same wattage as 2 series strings providing those strings are then joined in either series or parallel, surely only affects voltage and amps not watts or am I getting this wrong?
    I bought 4 SOK 206Amp batteries so far based on Will's glowing review. Either the BMS or the batteries are weird. I have multiple problems but here is an example: All of them are in parallel. 3 show about 90% charge, but one shows 0%, however all are at 13.4 V. All have now cycled at least once as shown in the BMS cycle count. I updated the BMS app to the most recent version. Any ideas?
    I have purchased a solar power system from Solar Edge which includes two EG4 inverters, 31 panels, but need a set of approved drawings for my building department. Suggestions?
    Looking for ideas. Trying to figure out what breaker to use for my eg4 lifepo4 48v battery bank besides the one each battery has built in.Any ideas?
    Hello, I am new to solar and I just have one quick question. I am looking for more of a back up system for SHTF kind of scenario. I kind of want to buy a kit. I don't need it to tie into the grid or anything crazy like that. I am looking at spending no more then $4,000 for now. I am looking for a kit that includes solar panels as well. I live in the desert of far west Texas with no tree coverage and open land.
    Has there been any discussion on the merits of bolted vs soldered connections of the high amperage wires to the BMS board?
    i see in the excellent tear down videos that Chins and Enjoybot (same company) are bolted, while Litime and Redodo are soldered.
    New to solar, I am buying a solar panel, I looked at the Epever Trace BN 40 amp controller, but it looks like the panel I am buying has higher VOC @ 222.9 volts
    what controller do you recommend?
    thanks in advance
    • Power: 460W
    • Open Circuit Voltage (VOC): 222.9 V
    • Short Circuit Current (ISC): 2.59 A
    • Maximum Power Voltage (VMP): 188.8 V
    • Maximum Power Current (IMP): 2.44 A

    You probably shouldn't get those panels unless you really know what you're doing. Look for some panels with a VOC of less than 60v max per panel.
    Hi Will. When you test for cold temperature charging cutoff do you see if the battery still produces power when the cold temperature protection is activated? It would be an easy cheat for a cost conscious manufacturer to add a cold temperature cutoff to an existing BMS by putting a low temp sensor in parallel (series?) with the high temperature sensor, disabling the entire battery on either high or low temp trips.
    IM KIND OF NEW TO THE SOLAR THING SO PLEASE PE KIND ... BUT I NEED SOME ADVICE FOR A DIY ALL IN ONE SYSTEM FOR RUNNING REFRIGERATOR AND COFFEE POT
    I HAVE 2 NEW 12 VOLT SEALED AGM DEEP CYCLE BATTERIES 100 AMP HOUR EACH AND A 345 WATT PANEL BUT WANT A 24 VOLT ALL IN ONE ..... WHAT DO YOU RECOMEND ?
    Would love to see customer service review videos. Awesome tech is great, but nothing is bullet proof. Some big name companies seem to be blackholes once the sale is made. Not sure how others feel, but I'd take an adequate product with great customer service over an amazing product with none.
    Hey Will, I’m a big fan of yours, I was wondering if you had done any research on ecat.com it’s an energy technology. I’ve been following for close to 20 years and is coming to fruition. It sounds a bit like Mr. fusion from back to the future but I believe it to be legit and I think that you would be very interested.
    1st post
    I want 2 install 800 ah, 24 volt house bank on my sailboat. I would really like to install 4 EG4s but the boat is in Sicily and Signature solar doesn’t ship to Europe.
    i see that Ampere Time does, also Enjoybot. Enjoybot only makes a 100 ah, 24 volt, so I’d need 8 of them. Ampere Time has a 200 ah battery, but 4 of those cost $1000+ More than 8 Es.
    Suggestions?
    Is there an EG4 distributor in Europe?
    TIA
    Will - Finally found link from Sig Sol Web and downloaded firmware but only contained firmware in Zip. Trying hard to do diligence to not bother ithers but not able to locate and download BMS_Test V? Any way to help me with an early Christmas gift from my Buddy Will.
    Watch your videos obsessively and can't thank you enough for being my sensi.
    Thx in advance Steve
    Hi Will! I'm building my 1st system and was wondering if I can/should put it together in my room, if so how should I go about grounding the system?
    Hi. I have a friend with the name Ben Mountou, and his Email is mountoubenriche242@gmail.com

    He tried to register on your forum a few days ago. But he never received any E-mail from there to complete the registration. So, he asked me for help to contact you on his behalf.

    Could you please take a look at the status of that account (by Email) and authorize its usage?

    Thanks,
    Alex

    Have him try to post, I joined yesterday, didn't get an email.
    Hi. I’m new to this forum and new to solar. Recent events however have prompted me to follow your videos and I am thinking along the lines of the Growatt 5k all in one with some Canadian solar panels or silicate, both of which I can get here, but most batteries recommended on u tube are not available here. Any advice to get me started in UK with items available here would be most appreciated
