Technical FAQs 4

Do solar PV and battery storage support stand-alone loads?

Both solar PV and battery storage support stand-alone loads. The load is connected across the constant DC output. 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.

How does a DC-DC converter work in a solar PV plant?

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 the battery is fully charged and the load is less than the PV power, the solar PV operates in constant-output DC bus voltage control mode.

What is a DC-coupled solar battery?

A DC-connected energy storage system connects to the grid mains at the same place as the solar panels; this usually means that they share a ‘hybrid’ inverter. You can think of this as a ‘one box’ solution, because there is only one inverter instead of two.

What is a PV converter & a battery?

In addition to saving PV energy during the day, the converter and the battery also act as an energy storage for the PV power during a grid outage, where that power is lost in a traditional grid-tied system without storage or even in an AC-Coupled system. It is a design choice cooling down time after a grid outage has occurred.
