My batteries seem to be consuming more electricity from Solar PV than desired to charge, resulting in grid electricity use when I don't want it:
i.e.
0.73kw generating
0.410 kw load
but 0.427kw to battery, meaning I have to buy supplementary power from the grid.
- Is there a minimum battery charging power / current?
- Can I adjust it?
I want the battery to charge only when there is surplus power, otherwise it is pointless - I might as well not have it.
Thanks in advance,
