“Very easy to fit and works exactly as expected. Build quality good. Quite easy to program for e.g. economy 7 use overnight. Only very minor issue which could have been mentioned in the details is the fan noise which comes on intermittently when the unit is putting power into the load an a faint whine even when not under load.”
“The unit is well built and made to last, and you were the cheapest on the market. You were also extremely prompt with your delivery.
We've used it to supply electrical power to our immersion heater, and when that's up to temperature, to supply a convection heater in our Conservatory. We stopped using this convestion heater as it was so expensive to run, but now we're using any surplus energy generated by the PV system for firstly hot water, then heating.
I would recommend you.”
