We're reducing prices!

1.1.2024

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

1.9.2023

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

8.1.2023

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

22.8.2022

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

25.2.2022

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.

SINEDRIVER®

This is our experimental power converter that is controllable by an external signal. This converter can adjust the power of the thermal load by changing the amplitude of the alternating supply current without changing the other parameters of the supply current. The frequency and sine wave remains, so it is an AC/AC converter.

Within the WATTrouter ecosystem, one of these inverters can replace one SSR up to 10A.

Parameters and Properties

Maximum power consumption of the connected appliance 2kW (9A).
Does not change the voltage frequency, it remains 50Hz.
Does not change the voltage waveform, it remains sinusoidal.
Smoothly changes voltage amplitude in one percent steps.
Control using PWM or 0-10V signal.
Reacts very quickly to power change requests, response within 10ms.
It does not create flicker like any proportional regulation using SSRs and zero-switched triacs.
High frequency and radio interference is low enough.
Protection against overload and short circuit of the appliance.
Protection against load disconnection (e.g. by thermostat).
Active temperature-controlled cooling, the fan only switches on when a certain temperature is exceeded.
In standby, it disconnects the power part including EMI filters, i.e. reduces idle consumption to a minimum.
In the steady state, with active regulation, the current to/from the network is always zero (if the PV inverter output is also sinusoidal).

This inverter, together with our wattrouter, is able to reduce the excess energy to the network to an absolute minimum, typically several tens of Wh per day (if the appliance connected to the inverter is still active and the power plant's output does not exceed its power input).

Two SINEDRIVERS running at our demo location.

Production and Estimated Price

This converter is not yet in mass production and the production start date has not yet been determined.

The estimated price of the converter will be 400 EUR.
