Document Number: 358-010324-02
Product Overview
The IVEM8048 8KW is a solar inverter designed for efficient energy management. It features "Smart Load" capabilities.
Operating Temperature Range: -10°C to 50°C
Dimensions: 607 × 464 × 141 mm
System Indicators
The inverter is equipped with several status indicators:
- Lithium battery type indicator: Indicates the type of lithium battery connected.
- Communication indicator: Shows if communication is established between the inverter and the battery.
- WIFI link indicator: Displays the status of the Wi-Fi connection.
- First AC output indicator: Shows the status of the primary AC output.
- Second AC output indicator: Shows the status of the secondary AC output.
- PV working indicator: Illuminates to show that the photovoltaic (PV) system is operational.
Communication Ports
RS-232 Communication
For connecting the inverter to a computer, an RS-232 cable or a USB to RS-232 conversion cable is required. Users must provide their own USB conversion cable.

Note: When operating in lithium battery mode, ensure that communication between the inverter and the battery pack is normal.
Instruction: Configure the battery type to "Lib" in LCD setting No. 08.
Parallel Connection
The IVEM8048 8KW supports parallel connection for increased power output. This involves using a current-sharing line and parallel wires to connect multiple inverters.
Diagram Description: A diagram illustrates the physical wiring required for parallel connection, showing how multiple units are linked together via specified communication and power cables to operate as a single, higher-capacity system.
Troubleshooting
Refer to the following for common error codes and their resolutions:
- Error: DC/DC hardware overflows
Action: Restart the unit. If the error recurs, the unit may require repair.
- Error: Overvoltage occurs in BUS
Possible Causes: AC surge, PV surge, or internal component failure.
Action: Restart the unit. If the error persists, return the unit for repair.
