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 ECO is versatile programmable controller to optimize self-consumption of energy produced by photovoltaic or wind power plant. There is possible to connect 4 external solid state relays (SSR). Current measurement range is 3x20A. When properly installed and configured, this controller maximizes the usage of produced surplus energy in your house by "routing" it to your loads. According to the price differences between feed-in tariff and normal electricity tariff in respective country and the amount of energy the customer can self-consume the device can pay itself within less than 4 months!

WATTrouter ECO consists of 2 modules - current sensing module and regulator. It can be configured and monitored from any IBM compatible computer or notebook over the USB interface.

WATTrouter ECO fully replaces the older models WATTrouter CWx. Developmentally based on WATTrouter M, WATTrouter ECO integrates standard design of some of its properties while maintaining a very low purchase price.

WATTrouter ECO is completely silent, because the power triacs known from WATTrouter CWx were replaced by SSR outputs that connect to passively cooled power SSRs. There are therefore four SSR outputs. This eliminates problems with fan noise, dust and the necessity to repair damaged controller in the event of power triac short circuiting. Power SSRs can also be dimensioned according to the connected load and cooling options.

For WATTrouter ECO there are also available optional software add-ons. These include some features that can be found as standard equipment of WATTrouter M/Mx. These optional features can be purchased separately and activated in the controller.

WATTrouter ECO can also be equipped with the SC-Gateway and SC-Router wireless interfaces which we developed in cooperation with the Czech company ENcontrol. These modules allow fully-fledged wireless data transfer between two regulators, all output control modes are supported now. You can also use a wireless socket modules from ENcontrol. This interface will be useful wherever it would be difficult to fit the cable connection between the regulator and the appliance. See information about supported ENcontrol wireless components.

WATTrouter ECO is an ideal choice for users who want effectively use their photovoltaic surplus energy without massive investments, they don't need increased connection comfort (monitoring via Internet, etc.), but they need a reliable and functional product.

Important note: The commissioning of the continuous regulation of the appliance (eg. an immersion heater) according to the available photovoltaic surplus energy always needs at least one power semiconductor relay - SSR.

Note: If you have a WATTrouter CWx or WATTrouter CWx SSR controller, then you can only purchase a standalone WATTrouter ECO controller. The current sensing module is functionally identical for both types, it only has a different label.


We deliver accessories for WATTrouter ECO. These accessories are solid state relays and others.
