4.3 Electrical Installation
4.3.1 AC side lines connection
1. Measure the voltage and frequency of the grid access point, determine the grid specifications
conform to the inverter.
2. Suggest increase the ac circuit breaker or fuse, the specification of ac output more than 1.25
times the rated current.
3. The inverter of PE line (ground) must be reliable grounding, ensure that the impedance
between the zero line and ground wire is less than 10 ohms.
4. Disconnect the inverter and grid access point of the circuit breaker or fuse.
5. It is recommended to use copper wire, if you need to use aluminum wire, please consult the
inverter manufacturers.
6. Follow these steps to connect the utility and inverter.
Step 1: Choose the appropriate communication cable and wire stripping out, specifications,
please refer to the table below.
