Grid-connected solar battery options. The orange box is the existing grid-interactive inverter. In option 1, the batteries (green) are added between the solar panels and the inverter.

Grid-tied inverters serve the purpose of converting Direct Current (DC) generated by solar panels into Alternating Current (AC). The power converter to AC is transferred to the utility grid and then from there to the appliances. Excess electricity generated and unused during the day is fed into the grid and the owner receives credit for it.
The Tesla Powerwall 7 kWh battery is designed to be installed this way. Another yet-to-be-deployed product is the Australian Sunsink. SMA already offers a grid-interactive inverter with 2 kWh of lithium batteries built-in, although its price is relatively high.
Specifically, in grid-connected mode, the inverter was responsible for the DC-bus voltage control and the reactive power control from the DC to AC side. Through the Phase Locked Loop (PLL) a reference current for the inverter was extracted. Moreover, the power flow of the battery converter was regulated using a PI controller.
Considering the price, then this one among the best grid tie inverter with battery backup is a good option also. The Y&H power limiter inverter has an in-built limiter which is why it is named. This limiter prevents the inverter from supplying excess power to the battery or inverter.
