The status of the inverter can be monitored via the communications interfaces using a PC with the monitoring software “Solar control”. The software is free. The software will be downloaded from www.clenergy.com.au/download.php. Download the “SPH - Monitoring Software V1.26” and install in your computer.
If inverter works normally, the LCD display panel will show “Working mode” and power is delivered to the electric grid. Otherwise the LCD display an error. Page 22 of 26 Clenergy SPH Installation and Operation Manual...
