Hi! My name's Dave, and I'm new to the forum and to solar power. I live in a very sunny part of Mexico (Oaxaca state, on the coast), and just installed a system that's supposed to generate an average of 5.5 kilowatt hours daily, more than enough for my smallish house. Everything is working well except that the inverter is only showing 91 volts. The panels and batteries are wired for 24, and the inverter is a 24 volt system. The panels read around 35 volts, the batteries (four 6 volt batteries wired in parallel/series) at 24.
For a short time we had the panels and batteries wired for 12 volts until we realized that the inverter was for 24. Would anyone know the probable or possible causes for the inverter not producing 120 volts?
I read that some systems have a low voltage output until appliances begin to draw current, at which time the system bumps up to 120 volts. But I ran an electric drill on it and the inverter and wall plug remained at 91 volts.
Thank you for your help!
