• Your advantages and highlights
• Ensuring hot water supply
• Legionella program
• Retrofit existing systems - Compatible with 1.5" E-socket
• Heating support
• Smart touch display control
• Easy installation
• Plug&Play
• How it works in detail

As soon as the sun shines, the PV modules generate electrical voltage and current flows through the Nexol Energy Controller. There, the current is conducted with low loss to the DC coil of the AC/DC screw-in heating element, which immediately begins converting the energy into heat and heats up the tank. In bad weather or when the sun is not shining, the Energy Controller can additionally use grid power for reheating.

• Why it's worth it

Depending on the energy source, different savings potentials arise. These can be well illustrated by the following key figures:

50% - Energy cost savings compared to gas boilers. That means up to €150 savings per year.

75% - Energy cost savings compared to electric boilers. That is up to €300 savings per year.

90% - Use over 90% of your generated solar power yourself - maximum efficiency and savings for you.

The system offers flexible setting options for different user types. You can individually set how often per day reheating occurs, up to which temperature the water is heated, and from which PV power this happens. This way you always have full control and can be sure to always have enough hot water available.

To kill legionella, the water in the tank must be regularly heated to at least 60°C. There is a standard activated program for this. The interval between heating cycles can be flexibly set to 1-14 days, with an interval of 7 days preset. The Energy Controller starts each interval after the last reached temperature of over 60°C. If this is not reached, the system automatically activates reheating via the grid.

• Quick and easy installation

Simply connect the PV modules directly to the Nexol Energy Controller via MC4 connectors. This is additionally supplied with power via a conventional mains plug. The screw-in heating elements in the hot water tank can be easily connected to the controller via plug after installation. This way you benefit from cost-efficient hot water in no time.
