Commissioning
Startup / Shutdown Procedure
The inverter must be installed by a qualified / licensed electrical engineer in accordance to the countries wiring regulations.
Only after the engineer has completed the earth bond, RCD and earth leakage tests, check the solar panel Voc voltage (must not exceed 450V) and check the battery voltage. Then, the inverter can now be switched on.
Power On Sequence:
- Press the start button to on position.
- Switch on AC.
- Switch on the DC (PV isolator).
Shutdown Sequence:
- Switch off the PV isolator.
- Switch off AC.
- Press the start button to off position.
Information for Commissioning the Inverter
After you have successfully powered up the inverter, the inverter must be programmed and set up as per the programming feature above.
| Check the earth bond on the solar panels. | Check the Voc does not exceed 450V. | ||
| Measure the supply voltage, check it matches the settings of the inverter. | If it falls out of the setting range it will cause the inverter to shut down and alarm. | See grid set up page. | |
| Check the battery charge and discharge is within the C rating of the battery. Too high will damage the battery. | Check the battery BMS is communicating with the inverter. | ||
| This is the heart of the system, this controls everything. | Ensure you are familiar with this, if you fully understand the controller you will fully appreciate the capabilities of there inverter. | ||
| Familiarise yourself with common fault codes. |
GFDI Fault
Before the inverter starts to connect to the grid, the inverter will first detect the impedance of PV + to ground, and the impedance of PV – to ground. If any of these impedance values is less than 33k, the inverter will not connect to the grid and will report an error F24 on its LCD.
