Anyone could clear up/confirm the following?:
- In stand-alone systems: Whenever the charging process is in BULK mode, PV power will feed the load demand and the excess will be used to recharge the batteries. If batteries are full and the load demand is less than PV production - current absorbed by battery, the inverter will shave the PV excess at its output.
- In grid-tied with battery systems: Whenever the charging process is in BULK mode, ALL PV power will go to the batteries and any loads are fed from the grid. It is also optional to allow the grid to participate in charging the batteries. When the charging gets to the ABSORPTION MODE, batteries only use a certain amount of current and all the remaining goes to the loads, offsetting consumption from the grid. If PV production is less than the demand load, the remaining can be obtained either from the batteries or the grid.
