Generation of the system can simply be viewed on the display unit of the inverter or through local & remote monitoring which can be performed by most common connection techniques like RS232 for local monitoring, RS485 and powerline for inverter interconnection. For wireless connection Bluetooth, GSM & Wi-Fi are most common used.
An inverter measures parameters like:
- Immediate DC voltage and current readings from the PV array
- Immediate AC voltage and frequency readings
- Output power (W)
- Lifetime energy produced
- Switch-on/off time for the day
- Up-time & Down-time for the day
- Cumulative hours of operation (h)
