Hope i am not about to destroy anything!
So after a few years of struggling with my first attempt at solar at our cabin in northern MN (no grid within 5 miles) i learned that 1) i didn't have a clue 2) any time without a generator running is priceless! The first attempt consisted of 2 15 watt 12 volt panels that advertised on the box you can run this and this and this. 4 105 ah expensive Concorde agm's and a home built charge controller 2 stage bulk and float. well i am sure you know the rest of the story, the batts sulfated to almost no capacity and we limped along with a home built batt charger using the same 2 stage control circuit as the charge controller and a Honda 2000i. Hardly ideal. After our serval fridge tried to kill us one night (burner malfunction) we decided to upgrade large enough to run a small fridge( 3.1 cube top freezer 2 door Edgestar actual draw 82w at start up settling down to 62w running.) The new system consists of 2 300 watt Renasola vmp36.6 imp8.2 in series on a home built tracking mount( Redrock module.) feeding a Morningstar Prostar 25 charging 4 Fullriver 115ah agm's wired series parallel for 24 volts. The batts feed a Aims 1500 pure sine 24 volt inverter (.7 amp dc at idle) So i installed the system during our 2 week vacation and turned it on. Everything seems fine but no remote meter(rm-1) well i get a batt symbol and the ah are increasing. no min/ max volts no array volts ect Morningstar is sending a new unit. so vacations over, i left the system running with the fridge as the only load and locked the door. When i got home started researching meter problem and stumbled across this forum and after a few hours of browsing realized that once again i really don't know for sure if i am about to ruin another set of batts or not. any help determining if this system will run 24/7-365 would be greatly appreciated
