For a house with two apartments with a PV-system and a shared water boiler (3 kW heating unit),  the already installed energy monitor WEM3046 T in combination with a SCR-module is planned to control self consumption for the water heater.

The water boiler is one phase.

Results are posted as soon as the system is installed.

please provide the spec of the resistive load, like this https://www.solahart.com.au/products/solar-water-heating/solahart-l-series/302l/

we need to confirm whether the load is compatible with SCR-485 (voltage and current are within the rating of SCR-485)

The activity of the first batch sample testing will end soon. 

Looking forward to your further information.
