I have read and seen in videos, Will included say that there can be problems with over three batteries in parallel.

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?

Awesome! Thanks for the info! I will check out my inverter and see if I need to swap the red and black cables. By disconnecting those ground wires on your white inverter, you have disconnected the neutral ground connection at the inverter, so that you can bond them at the breaker box, correct...

The sun is down now, so no power going in, and now all 4 batteries show 13.2v. Was there nothing wrong to begin with, and only showing higher voltage on the outside two batteries because they are the ones connected to the scc?

I may try that. Yes, there was power coming in from the scc and going out through the inverter when testing the voltage.

I disconnected everything and using a thinner gauge wire, I got them all to 13.48, and connected them all in parallel and let sit for 30 minutes. They all where at 13.48v, so I disconnected everything again, and wired them in 2s2p. Outside left is + and outside right is -. Hooked it back up to...

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

I have 4x 12v 100ah batteries in 2s2p for 24v. Today my inverter set off an alert, so I checked the battery voltages, and putting a volt meter on each battery, the voltage is different. On both of the 2s batteries that make the 24v one is 14.1 and the other is 13.3. How is that even possible...

I just received a reliable brand 24v 3000 watt inverter, and the fans are constantly turning on and off. On for 26 seconds, off for 10 seconds and repeats that. My current load is a midea u ac, that is pulling less than 600 watts, and a mini fridge that pulls 100 watts, so ~700 watt load on a...

What other details would you like? When doing the continuity test on the generator 30a plug, I did not know which was hot and which was neutral, so I put the black probe in ground, then put the red probe in both of the other spots, and got continuity on both. It makes sense that I did not...

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 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...

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.

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?

How so? Disconnecting one of the pv cables made the screen show the correct battery voltage, and voltage from the terminal on the mpp was within .02 volts of the voltage on the battery terminal. Sounds to me that the discrepancy is in the mpp unit when it is getting power from pv, the screen...

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 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...

Awesome! Thanks for your help, crisis avoided. I just remembered I have another option of a 10 amp variable dc power supply, that I used when I built the batteries. I might set it to 25-26 volts and 9 or so amps, and see if that wakes up the bms. I think it should. If not, I can move to the rc...

I have some extra panels that I could rig something like that up with. I have some 100 watt panels that have 22.6 open circuit voltage, and I have some 230 watt panels that are 37 open circuit voltage. Or, I just remembered I have a couple rc car/truck chargers. Maybe I could set one up to...

I have a situation that I am unsure how to resolve. I have 2 mpp solar lv2424 all in one charge controller, inverters, and a victron 75/10 charge controller, all connected through buss bars to 3 24v 100ah lifepo4 batteries. This setup has been up and running for almost a year. Now, none of the...

Exactly. Yes it was ebay. eBay and that other site named after a river in South America where the only places that had it available. I am starting to think they had a bad run, that will not charge 24v batteries, and that is why there are none available from reputable sites.

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...

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 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.

I have an lv2424 with 2) 24v 100ah batteries in parallel. 9 230 watt solar panels wired in 3s3p. Each solar panel has a ocv of 37, so that puts it at 111 ocv, which is under the max voltage of the lv2424. I also have a 4550 watt inverter generator, that I run to the ac input on the lv2424, and...

I have an mpp solar hv2424, and a Westinghouse igen4500df generator. I remember seeing somewhere that you can wire the lv2424 to start a generator, but I can't find it now. On the lv2424 there is the plug marked nc c no, and that would be the relay to tell the generator to start once battery...

I posted a picture yesterday at 10:50pm.

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.

These are not prismatic cells. No qr code. Here is a pic from when I was top balancing some of the good ones.

No qr code, or manufacture date. They are 3.2v 100ah packs of 32640 cells.

I did not. In hindsight, I should have.

They where all still in the boxes that they shipped in. Two of the orders, were in my RV, and two orders where in my enclosed trailer. It has been over 90 degrees where I live, but my enclosed trailer has decent ventilation, and is usually cooler inside than out. My RV has been plugged in and...

These are the order dates. 2/18/22 1/6/22 10/10/21 8/19/21

So, the place that I ordered them from should replace them, correct?
