I have a 90 watt SONALI solar panel connected to standard lead acid batteries via a Sunforce 30 Amp Digital Charge Controller set up by the previous owner on my Beneteau 331. I would like to add another panel, but I am told the 90W is no longer available, but an 80W with similar characteristics from the same company is. Comparing panels: (90W 1st & 80W 2nd) - Max Power 90/82.29 W, Voc 22.2/22.56V, Isc 5.48/4.90A, Im 18/18.4V, Max. Series Fuse Rating 8/10A, Max Syst. Voltage 600/700V UL/1000V IEC. My basic questions:
1. Would the 80W connected in parallel with the 90W create any problems for me. 2. Would the 30A controller handle both OK? Any relevant help will be greatly appreciated, keeping in mind my education with respect to advanced electrical matters is pitiful.
