Reverse power relay (RPR) for solar is used to eliminate any power reverse back to gird from an on-grid (grid-tie) PV power plant to the grid or to the generator by tripping either on-grid solar inverter or breaker or any contactor depending upon the type of power distribution and a.

Solar panels generate direct current (DC) electricity, which flows in a single direction. Reversing polarity disrupts this flow, confusing charge controllers and inverters designed to handle unidirectional current.

in short, yes it is safe to charge your battery while the inverter is connected. but the only thing to keep in mind is that the load connected with the inverter should be even to the input of DC power to the battery from the solar panels.
