I have 8, 290ah Eve lifep04 cells in a 24v pack with a jbd bms. I use a mpp solar 24lv unit with 1200 watts of solar. I changed my charge controller settings to 27.4 float and cv as it was limiting my solar input. I went from 400 watts to 900 watts when charging. however, my batteries are...

I have 4 panels, 305 watts each. Wired 2s2p. They are on the roof which is at different angles /-\ . I also installed a tilt system on one side. This means each row of 2 will put out different voltages. I have the rows wired to together for 70-100 volts, and then those 2 lines go into a...

I bought 8 grade 8 cells from Amy. They all tested at the same voltage when they arrived. Since they are matched and at the same state of charge, do I need to do a top balance charge each cell?

Overkill solar is out of stock on their 24v bms units. Whats a good alternative thats in stock? Looking for 24v 100a+ Thanks!

Can I have 1, 120v ac line that is connected to two inverters. I want to run a 300watt inverter all the time, and cycle on a 2400 watt inverter as needed. Do I have to turn the 300 watt off, or can both be running at the same time?

Have an old MPP (or similar brand) LV2424, 24v, 2.4kw 110vac inverter, 80a mppt system (or something close) sitting around that you've been meaning to sell? Sell it to me!

I want to use a lv2424 to run some large loads in my RV. I've read the idle power consumption is 25 watts in power saving mode. But what is the power consumption if you turn the inverter off and just use it as an MPPT/ATS? Is that possible?

I have 4, 305 watt panels rated at 39.3 volts and 9.9 amps. I'm looking at this all in one unit. The MPPT is rated at 40 amp 105v. Can 2p2s the panels for 80 volts 20 amps so it works with the mppt?

I want to run an A/C off my 1200 watt solar setup with 560 ah of batteries. A 9000 btu 17 seer mini split a/c unit will use around 650-750 and up to 900 watts A 12000 btu mini split uses an average of 900 with up to 1100. If they are both inverter mini splits, wouldn't they use the same amount...

I'm building a large solar system to run a 700watt minisplit a/c in my RV. I've got 1300 watts of solar panels that are 33v 9amp. I'm going to use a 1500 watt 120v inverter to run a fridge and the A/C. My goal is to power the a/c with solar during the peak sun and maybe a few hours at night. I...

I bought 4, 300 watt split cell solar panels. They run at 33 volts, 9.2 amps. My goal is to run a 700watt air conditioner in an RV during the day and a few hours after night. I bought them without realizing I would need such a large MPPT charge controller. It seems at 12v that I need at least a...

I've read a lot of threads and it seems that Amy and Michael are the best options. But its tempting to order from one of the cheaper vendors to save a few hundred. Any cheap but good options out there for 280ah Eve cells? Are 280ah Lishen cells a good option? Those go for like half the price...
