we need more info about your inverter. To charge batteries through your inverter the inverter must be an inverter/charger. If it is not then you will need a separate charger. I'm guessing you already have solar panels to charge your batteries, is that correct?
I agree with rmaddy since there is a question with the voltage of the panels then wire your panels in 2 parallel and then series those with the other 2 panels in parallel (2s2p)
The voltage is too close to take a chance of burning up a controller
Rinot you are correct, you want to keep your battery bank at 24v so you can power your inverter. From what I see you could put your 4 panels in series and run the 87v into you charge controller. Your charge controller will reduce the voltage and charge the 24v battery bank.
I hope I understood...
I need to replace 2 low cells in my 48v 310ah diy bank, and in looking for replacements I notice that most all 280ah cells and larger are all the same physical dimensions. 72mm x 173mm x 208 mm. So my question is are they all basically 280 ah cells and some test better than others so they sell...
I took some 2x2" alum angle and cut it into 4" lengths and screwed it to the sides of the solar panels. Then screwed down through the angle and into the roof to secure the panel to the roof.
I helped a friend mount his panels to a metal roof and we used aluminum angle of the side of the panels and down onto the metal and spaced them so we screwed into the wood supports under the metal roof. Not very expensive for the angle and easy to cut into short lengths.
I have contacted her or one of her coworkers and the batteries I want have a 4 cell minimum. I only need 2. I did find 2 cells on E bay and bought them but after I did a capacity test it turned out they were not as advertised. I had to return them.
If so I would like to add to your order. I need 2- 310ah cells. If you are going to order I would of course pay you in advance and either pick up or pay you to ship the batteries to me. Anyone?
I bought 16 310ah cells and made them into a 48v bank but during use I noticed that I wasn't getting the amp hours I was expecting so I did a capacity test on the bank and instead of the 310 ah I should get I was only getting 280ah. Looking at the bms I saw that cells #6 and 10 were low. I...
Funny you should ask, I just built a starting battery for my 2020 Polaris rzr. I used 4 25ah lifepo4 cells and a 200 amp BMS, put it all into a box approximately the size of the stock battery in the rzr. Before I did the swap I checked the voltage of the system and with the lead acid battery the...
I bought 3 of the GYLL 100ah 48v batteries from signature solar in March of this year and have been using them for 6 months now with absolutely no problems except that I am a computer idiot and I cannot get my computer to "see" the bms in these batteries. I am in the process of building my first...
I have 3 of the Gyll 48v 100ah batteries and have been using them since March this year. No problems with them except that the BMS is only available through a usb connector and a computer. I have not figured that part out yet. Other than that they work just fine. No complaints.
