5.5 Precaution For Initial Startup
1. Make sure the AC circuit is connected and the AC breaker is turned off.
2. Make sure the DC cable between inverter and PV string is connected, and the PV voltage is
normal.
3. Turn on the DC switch, and set safety country according to the local regulation.
4. Turn on the AC breaker. Check the inverter work is working normally.
5.6 Special Adjustable Setpoints(Only for Australia and New
Zealand)
The inverter has a field in which the user can set functions, such as trip points, trip times, reconnect
times, active and inactive QU curves and PU curves. It is adjustable through special software. If
needed, please contact after-sales. To obtain software manuals, you can download them from the
official website or contact after-sales.
5.6.1 PF Power Curve Mode
PF power curve mode can be modified by Modbus communication method, specifically according
to the inverter Modbus address and Modbus register value, according to the set range in the set
