Battery white repair
240KW/400KW industrial rooftop - commercial rooftop - home rooftop, solar power generation system.
But, if battery still shows white and shows 11 v, then, regular charging to regain 12.6 v and green colour takes about 10 hrs. This automatically implies that eye indicator is more precised than the voltmeter reading. So, a 12.6 v on battery without eye indicator may be misleading to the idea that battery is full charged!!! –
