Technical FAQs 4

What does a grid connected inverter do?

Photovoltaic grid-connected inverters rely on the large power grid to operate. When the power grid is disconnected, the grid-connected inverter will be in an island protection state and stop working. Its main function is to convert solar energy into electrical energy and transmit it through the power grid.

What is the difference between hybrid and off-grid inverters?

Hybrid inverters are connected to the grid and can operate in various modes, including exporting energy to the grid and providing backup power. Off-grid inverters, on the other hand, are designed for standalone systems that are not connected to the grid and rely entirely on solar and battery power.

What is an off-grid inverter?

Though fundamentally an off-grid inverter, this versatile model features grid input support—allowing it to draw power from the grid when solar and battery resources are insufficient. Commonly known as an off-grid hybrid inverter, it combines solar + battery + optional grid power, ensuring uninterrupted energy supply.

Why do inverters need to be disconnected from the grid?

When the grid power is off, the inverter must disconnect from the grid to guarantee safety and prevent backfeeding electricity, which could harm utility workers. The inverter design plays an essential role in enabling this grid disconnection feature, guaranteeing seamless operation during power outages.
