The Chint DDSU666 wattmeter is a single-phase meter that accurately displays the electricity consumption of the installation. The wattmeter reports this information to the inverter so that the inverter can adapt the power output to the current consumption. The wattmeter is compatible with DEYE inverters. Communication with the inverter takes place via the RS485 protocol.
The Chint DDSU666 wattmeter allows, if requested, not to return the excess of unused solar production to the grid. It also allows the measurement of the existing energy demand and, thanks to the inverter, it shows what the installation is able to produce. In this way, a comparison is obtained between the energy produced and the energy required.
The main features of this Chint DDSU666 wattmeter are:
- Single phase
- Up to 60 A
- 35mm DIN mounting
- Higher accuracy than Class 1
- Bidirectional measurement
