Hi, I have a greenhouse with a small solar system set up to run a small hydroponics system and I need help with it. I have 4 100 watt solar panels wired in series going to an MPPT charge controller to 5 100ah AGM batteries wired in parallel. I also have a 2000 watt inverter. The problem is I...

Sorry it took so long to reply. I expected to get an email notification and then I forgot about it. The smaller 50 watt panels are a different set up just powering 4 12v fans as an experiment Thanks Maria

Thank you. Just one mor question. When I connect the new cables can I connect them both to the same batter or does one have to be on the first battery and one on the last battery? Thanks

The panels are 4 100w 18.6v panels wired in series. Thanks

The panels are 100w 18.6v wired in series. These panels are about 5yrs old would it be better for me to invest in a couple of 200w panels wired in parallel instead of the 100w wired in series? Thanks

I have the inverter connected directly to the battery. I have a 12v timer connected to the scc that’s probably what you saw. What size wire do I need? Thanks

18.6 is the VOC
