I have an EG4 6000XP mounted on the wall of my garage about 3 feet from my breaker panel. I need to run 4 wires L1 L2 neutral and ground out of the panel to the inverter which is on the wall. The wire will exit the panel inside of flexible nylon conduit. I’m having a hard time coming up with a...

I have a DIY battery, 48 volt 560 ah. I’m considering buying the new EG4 chargeverter to charge my battery instead of using the inverter. I need a system that I can set and forget because I will be away from the system for extended periods. I don’t and won’t have a generator, so I must power...

I’m trying to find a generator interlock kit for my Murray LC240PC panel with 200 amp main breaker. Mine has the main breaker on the top left. I can find ones for a top left main breaker but not for mine. Does anyone know of an interlock kit that will fit this panel? Thanks

I received an instant message from an Alibaba supplier asking if I would be interested in a 51.2v 280ah server rack battery for only $950. Not sure what the shipping would cost but this seems crazy cheap?

I know this is a simple problem, and maybe I’m just not understanding how it mounts, but should a breaker slide back and forth on the din rail? I have tried three different ones and they all mount, but I would think they should stay in place? My don’t. They all slide back and forth and won’t...

I have a brand new EG4 6500EX-48 inverter that I bought for my project but never used. This is still in the original box and was never opened. Purchased from Signature Solar one year ago. I’m in East central Virginia, just south of Richmond. I do not want to ship, so local pickup only. Asking...

I’m trying to determine if my solar panels are working correctly. I have 12 Canadian Solar 250 watt panels, in a series/parallel configuration. Two paralleled sets with 6 panels in each string. The highest output I’ve seen so far has been around 1300 watts. Theoretically I should be around 3000...

Hello, Yesterday I successfully downloaded and installed Solar Assistant and have it monitoring Solar production on my system. I currently have six 250 watt solar panels in series, feeding my Growatt SPF 3000 ES inverter, which is connected to my DIY 14kw Lifepo4 battery. Everything seems do...

I recently built a 48v battery using 16 272ah Lishen cells. I finally got around to running a discharge test using my Growatt SPF 3000TL LVM-ES inverter with a 1600 watt heater as a load. I let it run and monitored the cells on the JK BMS app. The test ended when just one of the cells, #5...

I am trying to test Eve 280 cells using my Ebc-A40l tester. Just a note, I have already tested 8 Lishen 272ah cells with this same tester without any issues at all. However as soon as I attempted to run the same discharge and charge test on my Eve 280 cells I am having problems. Both the...

Let start off by saying that I’ve been reading the posts on this forum for 3 years. And I’ve searched for but couldn’t find an answer to my question. I have a specific requirement to be able to have a backup source of 120v A/C for some of our home appliances. I recently purchased an (1) EG4...

I found my answer after searching the forum again. Go figure.

Found this on AliExpress. 32 310 ah Grade A Lifepo4 cells with bus bars, shipped free from China for $810.00. Seems too good to be true?

I have two K2 energy 24 volt batteries. One reads 13.8 and the other 14.6 volts. I’m trying to charge these up but ny charger won’t charge them. I’ve tried them individually and in series but no luck. These are lifepo4 batteries. Has anyone had any luck charging batteries that have been this...

I have 8 each Lishen 272 ah and Eve 280 ah cells that I want to use together to make one 48 volt battery. I'm pretty sure that I can't just connect them all in series and use a 16s BMS. But can I create two 24 batteries each with their own BMS and connect the two batteries in series to make a 48...

Hi, I wound up with 8 Lishen 272ah and 8 Eve 280ah, all supposedly brand new. I plan on building two separate banks of 8 each Lishen and Eve and series connecting them with each bank having its own BMS. Has anyone actually done this? What was your result, any issues? In addition, if this works...

These seem too good to be true. First of all the listing says 280ah, when the label clearly says 272ah, possibly Lishen? But what really stands out to me is the price. $320 for 4 cells with free shipping from China? Something‘s not right.

Hi, I want to build a DIY solar system, using ground mount solar panels, a home built battery bank and all in one MPPT charge controller and Inverter. I plan on this being a backup for the utilities and it will not feed the grid. I went on the PIke’s Peak Regional Building Department’s website...

Hi, I'm new to building battery packs. I just bought 8 120 ah LIFEPO4 cells to construct a 24 volt battery. These cells have screw in M6 terminals. I've been reading as much as I can on the various forums and have recently seen posts talking about tightening screws, bolts and studs. Some of...

My 272 ah Lishen cells arrived, thanks to Michael Caro. I haven't been able to test them yet but I am very excited. They only took 7 weeks from the time I ordered them with Michael to arrive. I had originally planned on a 24 volt system, but have decided to go with 48 volt, so I will be ordering...

Hi, I'm trying to decide on buying an inverter. I am probably going to buy one of the Growatt SPF 3000 TL series 48 volt units. I have a question regarding the PV cable size for both units. Unless I missed something, it appears that for the manual for the SPF 3000 TL LVM the says to use a 6 AWG...

Hi, Does anyone on the forum have this inverter? Has anyone tried it without batteries? This is one of the units that when used alone, not in parallel can supposedly work without external batteries. My question is, without batteries does the unit draw power from the home AC? Can I test it...

Hi, I’m considering the Battery Hookup BMS but they are out of the Bluetooth module and no idea when or if they’ll have it in stock. Does anyone know of an acceptable replacement that will work with their BMS and where I might buy one? Thanks Dave

I am new to this forum and new to Solar. I have a basic knowledge of electronics though. I am trying to get an off grid solar installation going for my house. I have purchased solar panels that I will install in the Spring. For now I am trying to build my own 24 volt battery pack. I recently...
