The WATTrouter controllers are versatile programmable controllers to optimize self-consumption of energy produced by your photovoltaic or wind power plant. They provide non-electric accumulation without the need of expensive and inefficient batteries. 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 (typically daily or monthly periods).
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.
