Common problems
Performance Derating
The system will automatically derate output if the operating temperature exceeds 45°C or if the installation altitude is above 2000m.
Before use
- Ensure the installation site provides at least 1.28 square meters of floor space.
- Verify that the local grid voltage matches the 230 Vac / 400 Vac requirement.
- Confirm that the ambient temperature is within the -30°C to +55°C range.
- Prepare the communication infrastructure (4G, RS485, or LAN) to support Modbus TCP protocol.
- Ensure the site is suitable for a 2500 kg unit.
Specs in practice
