About Photovoltaic Energy StorageThere is a rumor unspoken rule : the slower charge the better battery, it seems charging current is around C/10 and <= 10A is more favourable to prolong lead acid battery. However, better read the battery specs and datasheet to find out. Example: Your battery capacity is 80Ah, C/10=8A <= 10A, then maximum charging current is 8A.
About Photovoltaic Energy StorageFor instance, if a charger reports that it can supply 2A, but the voltage doesn''t stay at 5V, the iOS device will consume less than the maximum current. It will not charge below 4.5V, nor above 5.5V. So not only does the charger have to present the correct signals to indicate full current is available, it has to maintain good regulation at …
