I hope everyone is alright by the grace of almighty Allah. I am using 24v Apollo Inverter with 2x 175A Ags battery since July 24,2016 + 620 watt solar panels inverex with 30A systek mppt solarcharger connected with this setup. Day time full on solar after 7:45 P.M or 9:45 P.M switch to wapda till 8:00 A.M Now after two years of giving good performance one of my battery become weak. After 4 hour of providing backup it drop to 9.6 volts while other battery is at 12-11.9 volts. I have one 12v homage Inverter. I want to connect it to only provide backup from one battery when the 24v ups shutdown (not want to connect it to wapda)
Please tell is this possible?
Jazak Allah and Thanks in advance.
