Equipment that uses electricity to operate is called a load. Loads are the largest single influence on the size of a PV system. It is better to supply some loads with power from other generating means to limit the size of a PV system. For example, powering an electric range in a home with a PV system can be cost-prohibitive.
This document examines DC-Coupled and AC-Coupled PV and energy storage solutions and provides best practices for their deployment. In a PV system with AC-Coupled storage, the PV array and the battery storage system each have their own inverter, with the two tied together on the AC side.
Both solar PV and battery storage support stand-alone loads. The load is connected across the constant voltage single-phase AC supply. A solar PV system operates in both maximum power point tracking (MPPT) and de-rated voltage control modes. The battery management system (BMS) uses bidirectional DC-DC converters.
In a PV system with AC-Coupled storage, the PV array and the battery storage system each have their own inverter, with the two systems tied together on the AC side. The two systems are thus electrically separated, allowing a customer to size each separately.
