This seems like a common configuration: connecting solar panels + MPPT charger to lead-acid batteries which are also connected in parallel to an inverter.
Assume that, momentarily, the battery has been charged fully (as per the charger's logic), the solar panels are supplying their peak power, and the inverter is drawing current. I would like to know what is happening inside the battery in the following cases:
- Both the battery and solar panel are capable of supplying the power requirement.
- The solar panel is not able to satisfy the power requirement, so the battery has to provide it.
Does the battery undergo chemical changes which count towards cycles of the battery? How to count these cycles which I assume are not complete cycles?
