Hi
I have fitted a PV Immersion heater to heat a single element in my tank when there is daylight. The installation seemed very simple and it appeared to generate some energy when I first fired it up, but a very small amount, since, it has not switched on the heater. The control box is displaying 'tank water hot'. But clearly it is not. I'm not sure how it would know this as all it has is power to the element and no loop to a thermostat.
My only thought is that it thinks it's getting power from the solar panels but is not switching on because the element will not power up.
I recently fitted a new thermostat, could it have simply stopped working?
The device that plugs around the cable I have clipped around the feed from the main meter to the fuse box, but there is a box between these two that connects the solar panels to the fuse board. I would assume that when the sender detects power going back into the meter, it switches on the heater. But this is not happening.
