GENERAL INFORMATION
WATTrouter ECO 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 ECO consists of a current sensing module and the regulator
itself.
WATTrouter ECO offers the following functionalities:
Three-phase indirect current measurement.
One phase detection of voltage necessary to determine the power direction on L1 and SW detection
to determinate the current direction on L2 and L3.
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 up to 6 outputs (2 relays and 4 external solid state relays SSR) based on configured
priorities.
Switching up to 6 wireless outputs based on configured priorities (only with SC-Gateway module).
Optimal use of surplus energy produced by PV-plant on 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 program 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 (night/low tariff) for CombiWATT. This is for households where double tariff
rates will apply.
1 input for connection of impulse output of external energy meter, which may measure any power
output. Measured value is displayed in WATTconfig ECO application.
Separated current sensing module and regulator for easy installation into existing household wiring.
WATTconfig ECO software designed for MS Windows, Linux and MAC OS X provides comfortable
controller configuration and monitoring via USB interface.
Real-time module backed up with a lithium battery for advanced management of outputs and
CombiWATT function.
Time schedules for outputs.
Day, week, month and year statistics (only with activated SW feature).
PWM mode for outputs allowing for proportional control of suitable heat pumps, air conditioners or
battery chargers (only with activated SW feature).
Firmware updates.
