Case Studies

System Overview

Diagram:  PV → Inverter ↔ Battery ↔ Grid → Loads（+App monitoring）

How it Works

1. Solar panels generate power first.

2. Inverter manages solar, grid and battery input

3. Excess solar is stored in a battery for backup load.

4. Grid or generator supplements when needed.

5. 0.01s switchover ensures critical loads never drop.

6 App & web monitoring gives you full control anytime.
