Where a solar battery lies within your solar panel setup will depend on the type of battery. Some batteries must be connected to the DC side of your system. With these batteries, the solar energy runs to the battery before conversion at the inverter. Some batteries are connected to the AC side of the systems, post-inverter in the energy flow.

This example uses a boost DC-DC converter to control the solar PV power. When the battery is not fully charged, the solar PV plant operates in maximum power point. When battery is fully charged and the load is less than the PV power, the solar PV plant operates in constant-output DC-bus voltage control mode.
The load is the energy consumption point, while the battery both absorbs and releases electricity for the load. Thus, in an off-grid system, the load can be powered by three sources: mains, battery priority, and photovoltaic. …
