We're reducing prices!

Dear customers, we have optimized our production processes and input costs, which is why we were able to reduce the final prices compared to the 2023 price list by up to 20%! If you are our partner (installation company, wholesaler), you will find the new prices after logging into your account. On the My account page, click on the link Your current price list. If you are not our partner, the final prices listed in the Direct purchase section apply to you.

End of rationing system

Dear customers, due to the availability of parts for production, we are stopping the rationing system for all products supplied by us from September 1, 2023. All products are now in sufficient quantities in stock.

Rationing system

Dear customers, due to the high demand, we are introducing a rationing system for our most ordered products from 9 January 2023. For more information about this method of purchase, see here. New registrations are temporarily suspended until January 16, 2023 to allow priority purchase for our long-term business partners.

Design change

Dear customers, due to better availability, from 22/08/2022 we deliver all our controllers in slightly different installation boxes, which are functionally completely identical to the original ones, only they are slightly different in design - they do not have the bottom sharp edge. The size of the controller, i.e. the number of modules and other parameters, does not change. The absence of the bottom sharp edge also objectively facilitates the installation of the controller in the switchboard.

End of cooperation with Russia

Today we ended our cooperation with Russia. No orders from this country are possible and no technical support will be provided. Also, Russian language will be removed from all our future software updates.

WATTrouter controllers

The WATTrouter controllers are programmable controllers to optimize self-consumption of energy produced by your photovoltaic or wind power plant. They generally provide non-electric accumulation. When correctly installed and configured, these controllers can perfectly optimize the surplus energy which would otherwise flow unused into public grid.

These controllers can be used for photovoltaics operated in "prosumer"-schemes in residential areas, where, according to the price differences between feed-in tariff and regular electricity tariff and the amount of energy the customer can self-consume, the devices can pay themselves even within less than 4 months!

These devices can even help for photovoltaics operated in net metering schemes where the energy flow compensation period is less than one year.

All WATTrouter devices support only 230VAC / 50Hz grid.

This solution is compliant with EN61000-3-2 and EN61000-3-3 for connected load sizes up to 2kW.


Classic WATTROUTER connection

A classic on-grid inverter without a battery is used in this connection.

Recommended WATTROUTER connection with hybrid inverter

A hybrid inverter with a battery is used in this connection. WATTrouter consumes only the excess energy produced, which cannot be used to charge the battery and other appliances in the house. In the inverter, the supply of surpluses to the grid must be enabled.
