I installed solar retrofit to an already existing inverter battery setup.

Now during daytime,inverter will be in battery discharge mode by converting DC from battery to AC for appliances use.While battery gets charged from solar panels during daytime.

During night, solar retrofit will not be working and inverter will work as usual. That is,inverter charges battery (AC to DC) from the grid and every appliance connected to inverter uses grid and there is no solar charging. Only when there is a power outage,battery will be used to power appliances connected to inverter (DC to AC).

Are there any ways to charge battery only by solar and not by grid?

    \$\begingroup\$ That may be possible depending on the make of inverter - some have everything controllable - others not. \$\endgroup\$

  • \$\begingroup\$ @SolarMike the inverter only has 2 main modes. Charging mode when grid is available and backup mode when grid is unavailable.Any other ways? \$\endgroup\$

    \$\begingroup\$ RTFM for the inverter, this is an example of a manual for a series of inverters in which most things are controllable: xantrex.com/documents/Discontinued-Products/… \$\endgroup\$
