I live offgrid on a farm. I have a 7.5kw solar pump inverter connected to 12kw array of panels. I recently acquired a silage baler that has a 5.5kw and 0.5kw motor within it. These motors work intermittently controlled by a vfd inverter within the control panel of baler. I would like to use the...

What would happen if I have 8 panels of 40v 10amp and I connect them in 4s2p configuration to power a dc water pump. On the other hand, I connect the same array in a series 8s configuration to charge batteries via mptt scc. I will have a switch between the two that I can flip to use the pump and...

I have a 16s Daly BMS. I need to balance my cells but do not have a 48v battery charger. I can split the cells into 4s and use a 12v charger, but I do not have a 4s bms. Is there any way to use the 16s bms but on a 4s battery configuration so I can charge them in 4 rounds using the 12v charger...

I just finished my setup. I am supposed to get at least 40amps from the panels but I am only getting 0.1amps as per the cc. The day is nice and hot. Panel voltage is 112v while battery bank is reading 52.6v. These are 16s 3.2v 280ah lifepo4 batteries currently at 50% soc. Why is the mppt only...

I have an epever 6420 AN mpppt charge controller. I recently purchased new EVE 3.6v 280ah cells ( or at least the chinese guy said they were new). I was wondering how to top balance the 16 cells. I get that I need to put them in parallel and charge to full charge. My issue is that the only...

I currently have an Epever mppt 200v 60 amps. (6420an). I wanted to parallel it to an Epever 200v 100amp, to charge the same battery from different pv arrays. The sales agent says it is not possible to do this. She says the scc have to be the same. I want to add a bigger array so another 60 amp...

I am dreaming of setting up this system. I have a small offgrid farm and need to run some solar pumps and have solar power. My dilemma is that the pumps take 19 panels in total yet they only run for a few minutes a day intermittently for a total of maybe one to two hours a day maximum. I have...

Hi. I have a dc water pump rated 110v-150v, 1500watts and has a controller with mppt function. I also have 8pcs 330watt panels that will be in 4s2p to give 160v 20amp. I have an epever cc 200v 60amp. I would like to connect both the pump and the epever scc (in parallel) to the solar array so...
