Hi anyone checked their domestic battery voltage in the hot sunny days in Spain . We live here & just out of interest I tested the voltage today at about 3 pm & they voltge was 14.6 volts is now just after 10pm & its dropped to 13.4volts . I have a solar panel & controller fitted . I was a bit worried these voltages were a little too high, anyone know if these voltages are normal ?
I have nothing switched on on the domestic side so there is no load or discharge . Thanks Bill
