GENERAL INFORMATION
WATTrouter M is a programmable controller to optimize self-consumption of energy produced by photovoltaic
or wind power plant (hereinafter referred to as PV-plant). It is a smart home energy management system. After
correct installation and configuration, the controller perfectly optimizes self-consumption of energy produced
by your PV-plant. WATTrouter M consists of a current sensing module and the regulator itself.
WATTrouter M has the following features:
Three-phase indirect current measurement.
Single phase detection of voltage necessary to determine the power direction in phase L1, for other
phases it is determined by software.
Evaluation of active power outputs in individual phases, necessary to determine the surplus of
produced electric power.
Regulation based on the sum of power outputs (summary surplus) from all three phases or based on
surplus in each phase.
Switching for up to 6 outputs (2 triacs, 2 relays and 2 external solid state relays SSR) based on
configured priorities.
Optimal use of surplus energy produced by PV-plant on triac and SSR outputs through the application
of proportional synchronous regulation of resistive loads, compliant to European standards EN 61000-
3-2 and EN 61000-3-3. This regulation modulates connected load's power exactly according to the
available surplus energy.
Very short average dynamic response of the controller (up to 10 s)
Optional CombiWATT function used for switching loads under a combined mode where energy is
taken both from PV-plant and public grid (especially suitable for water heating and also for swimming
pool filtering system).
Input for low tariff signal (nightly low price electricity) for CombiWATT. This is for households where
double tariff rates will apply.
3 inputs for connection of impulse outputs of external energy meters, which may measure any power
outputs. Measured values are displayed in WATTconfig M application and also on web interface.
Separated current sensing module and regulator for easy installation into existing household wiring.
WATTconfig M software designed for Microsoft Windows, Linux and MAC OS X, provides comfortable
controller configuration and monitoring via USB and Ethernet.
Integrated web interface allows comfortable controller configuration and monitoring using regular
Internet browser.
Real-time module backed with a lithium battery for advanced management of outputs and
CombiWATT function.
S-Connect protocol for sharing devices over existing network or wireless infrastructure.
Daily, weekly, monthly and annual statistics.
Firmware update.
