Charging storage battery from grid

[Ahmed Hasan]

Greeting All,

I am asking, How to enable charging battery storage from grid during night in or in case of cloudy day in PVsyst?

Thanks in advance

This is not possible in PVsyst in the present time.

This is indeed not pertinent in most cases: why charging the battery if power is available from the grid when necessary ?

Now there may be particular cases where this cous be useful. For example:

- in case of very weak grid, it could be useful for keeping a minimum of charge in the battery, for ensuring consumption in case of grid failure.

- If you want to store energy during low tariff period, for restituting it during high tarif period.  However this may be done in any system, even without a PV production. This is not considered in PVsyst.
