I intend to add in parallel 25vdc 30a external to my 21.8v 1400w panel source, to charge my batteries of 12v 600ah, for in the night there is no sunlight.
Will the external power disturb the panels? At night since there is no sunlight, do panel dissipate batteries power at night, because I measured the resistance of the panel in the night and in absolute darkness and saw about 70 Ohms.
Any advice thanks!
