So, quick breakdown. I have a 16' trailer that I use as a mobile workshop. I found that I can fit 6 160W PV panels on top yielding me about 960W.
The 12V panels will be in series pairs for 24V, 3 pairs to produce about 40A total, decided on an EPEVER 4215BN 40A charge controller, didn't oversize since I can't physically fit more panels, anyhow. Power will be going to 2 100Ah batteries in series for 24V. Batteries will output to a 24V/1500W Pure Sine inverter to run a dehumidifier @ ~600W. Hopefully everyone is OK with this math, I could always double my battery bank, later.
I'm hoping that the 600W dehumidifier runs intermittently, but I'm OK if it cuts out a few hours a day. I'm already aware that 960W IN for 6-8 hours isn't going to provide 24hours of 600W OUT, but it will certainly reduce my electricity bill.
I'm looking to purchase a Noco GX2440 40A, 24V battery charger to supplement my harvest and keep my batteries from running too low and cutting out the inverter. Some reviewers have been happy with this unit on their off-grid setup.
My question is: When and how should I have the GX2440 kick in? I would like if it could only kick on within a certain battery voltage range. I don't want to go below cut-out, but I also don't want to go above the point where I spoil my harvest. It would be a shame if the sun comes up, but the batteries are already fully charged from the grid.
I the 4215BN has a DC/load output, which can support a contactor relay. I'm just not sure if it can be programmed to operate within a certain window.
Any advice?
