Year-round combined system
With 1 heating element boiler
In this version, the controller must be retrofitted with an HDO module for the safe connection of the boiler heating coil between the controller with photovoltaic panels and the distribution system. The module allows you to heat water from photovoltaic panels during the day and heat hot water from the distribution network at a set time.
Heats water indefinitely even in winter
The advantage of the solution is that you can use a previously purchased water heater when building the photovoltaic system, thereby reducing the purchase costs and the economic return on investment in its own autonomy. At the same time, the amount of hot water is not limited by the lighting conditions of the photovoltaic panels. The HDO module also allows you to block electricity consumption at high tariffs.
