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.
