5. Setup and Installation
5.1. System Connection Diagram
The inverter can be directly connected to solar panels or battery banks. Below are common connection methods:
Image: Comprehensive system connection diagram for the inverter, including solar panels, battery pack, MPPT controller, grid meter, breaker, and load. Four matching methods are available: 1.A+C+D, 2.C+D+B, 3.A+B+C+D+E, 4.C+D+(A+E+B)x10.
5.2. Limiter Connection
The limiter function helps prevent excess power export to the grid. Follow these steps to connect the limiter:
- Connect the RS485 cable of the AC power acquisition meter to the 485 port of the inverter.
- Plug the connection terminal of the transmitted current sensor into the port of the collector "CT-IN" (no +/-).
- Connect the AC power supply port "AC-IN" of the collector to the same AC power supply for the load. After the connection, it will light up.
- In the inverter LCD, enter the "battery grid connection" menu, through the SET (Bat AutoLimit Grid).
- Connect the inverter to AC power first, then connect the battery. The inverter will automatically output the same power as the power detected by the collector. Therefore, the inverter will not have excess electricity to be sent to the grid (i.e., automatic limiter function).
- One acquisition meter can connect 5 unit grid tie inverters.

8. Troubleshooting
This section addresses common issues you might encounter with your inverter. For more complex problems, please contact customer support.
8.1. Common Questions & Answers
- Q1: What's the type of the inverter?
- A1: This series of inverters are grid-tie, they will feed power to the local grid. If you don't want to feed power to the grid, please choose the limiter version.
- Q2: What's the advantage of 500W and 600W, 1KW and 1.2KW grid tie inverter?
- A2: They can both work with solar panels and batteries. 500W and 600W grid tie inverters can adjust the AC output power. 1KW and 1.2KW can work with a limiter which can be a zero export function.
- Q3: What's the difference between LCD version and WIFI version for 1000W 1200W Model?
- A3: The LCD version just monitors the generating data on the LCD display. The WIFI version just monitors the data on the APP.
