Hi all,

The system was installed today after making all the connections. Solar power from the panels began to flow at around 12:05​ noon. Water temp in the tank was 15 degC. Approximately 1-1.2 kw of power was delivered to the water heater in the next 25 minutes or so which raised the water temp to 50 degC. The thermostat shut off the power thereafter. Test Video below.

The pic below shows the water temperature having risen to 50 degC. The mosfets are off as can be seen in the pic below with current down to 0.0. Water temperature can be seen on the left blue display.




Will keep testing to achieve reliable operation.
