Update, I added two more of the same solar panels, so now it is 2s2p of 230 watt panels. Currently the display says 13.6 volts and is only taking in 20 watts. Battery voltages where 13.66 on each of the terminals. I am guessing only 20 watts is because it is in float charge?

I have tried adding a 40 amp epever scc, and 2s2p of the same 230 watt panels to help keep up, and still getting 07 fault code on the lv2424.

Pretty cool.

I have an mpp 1012LV that I just set up, connected to 3, parallel 12v 100ah lifepo4 batteries all connected with 2awg copper. The display says 13.7 volts. My volt meter on the mpp lugs say 13.5 volts, and each battery shows 13.48 at the terminals. It has been in the sun all day yesterday and...

Thanks for the replies! I like the idea of facing one of the strings slightly se and the other slightly sw. With that in mind, can I add another two panel string, so it would be 2s3p? That way I could have 2 panels se, 2 straight south, and 2 sw? It is going to be a ground array, so I am...

Thanks Mike! I have a noco genius 10 charger, so I have that covered. The three 12v 20ah batteries would be about $140 cheaper than the 12v 50ah battery that Will recommended. Or, for not much more money than the battery that Will recommend, I could go with a single 12v 100ah.

The bms is not attached yet.

I have been checking on it every couple hours. I have yet to see above 13.66 at the batteries while the panels are in full sun. Yes, which is going in the right direction at least.

I only have 4x 100 watt panels right now.

Can I see some pics of your battery banks, that are made from the battery hookup 100ah packs? I have 5 of them that are all going to connected in parallel, and just looking for inspiration, and ideas on what you used to connect them. Thanks!

I tried calling the number on the battery hookup website today, and got no answer, and there is no way to leave a voicemail. I have not gotten a response from my last email which I sent 10 days ago. I have sent another email today, politely asking for help.

Did you figure anything out on this? I am having the same fault 07 on the lv2424 mpp, which I understand is made in the same factory as the growatt. I can run off of generator by itself fine. I can run off solar by itself fine, but if I connect the generator to the ac input on the lv2424, I get...

I posted a picture yesterday at 10:50pm.

I have disconnected all batteries at the moment, but left to right was 14.1, 13.3, 13.3, 14.1.

With the generator off and disconnected, I tested continuity at the 30a plug, which is what I would be using. With the black wire from multi meter in the ground, I get continuity on both hot and neutral. Does that sound right?

I disconnected the pv negative, and the voltage on the screen was within .02 of the terminal on the mpp, and within .04 of at the terminals, so that is not bad. It has never gotten that high. Only 13.48 at the battery. I have been turning the inverter off at night, and didn't turn it back on...

I am currently top balancing 8, 3.2v 100ah battery hookup packs all hooked up in parallel. I set the power supply to 3.65v, and letting it finish. After these are top balanced, I will hook them up in series (24v), then hook up the bms. When I go to add this new pack to my existing pack that...

I just purchased an Aims CON120AC12/24DC charger. In the listing and in the part number it shows it will change 12 or 24 volt batteries. I have seen Will charge 24 volt batteries with the very same charger. Here comes the weird part. It has a green sticker on the box that says it only supports...

I am wiring up a breaker box for an off grid cabin. No grid power of any sort on the property at all. Do I bond neutral and ground in the breaker box? The ground will be wired to an 8' copper rod outside. I read some other posts and they said adding a generator complicates things, weather the...

These equalizers say they are for 4 batteries in series, but would it work for 4x 12v 100ah batteries in 2s2p or 2p2s? Or hypothetically would it work with 4 batteries in parallel? Or for some reason for it to work, do all the batteries have to be in one series string?
