Check whether the energy storage battery is good or bad
240KW/400KW industrial rooftop - commercial rooftop - home rooftop, solar power generation system.
As you can see below, the voltage of the battery was actually lower than the bad battery! 12.26v vs 12.31v… With the car running, the voltage was 14.37 volts (compared to 14.39v!). This is a good lesson that looking only at voltage is not a true indicator as to whether the battery is good or not…
