Batteries: Two (2) AGM 100 AH 12 volt in series (24 volts)
Solar Panels: Two (2) 100 Watt in series
PWM Solar Controller
Primary Use: 25 cu ft Fridge and a couple of lights
I'd like to get a 24 volt AC charger and keep it on the batteries at all times so that when there is insufficient sun and at night, the batteries will stay charged. I can't seem to find the maximum charge level, float level and boost level for any of the cheaper 24 volt chargers that I have found on Amazon. Does anyone know what these might be? 24 volts for all three? 24 volts is probably too low(?)
I am also considering an automatic transfer switch (ATS) to switch back to the grid if the batteries' DOD drop below 50-60%. I think I understand how to install and configure the ATS, but am wondering about any problems that I may run into with the AC charger also installed. I don't think it'll be a problem, but I have been wrong in the past … lol.
Also, my understanding is to occasionally (monthly?) discharge AGM batteries some for longer life instead of keeping them fully charged at all times. Is this also the consensus?
Thanks for any help.
