AtonPower to Heat Meter

SHARE

ATON is a plug & play solution for using surplus PV energy – without additional wiring. It consists of an energy meter and an immersion heater, which can be variably controlled from 50 W to 3 kW, for installation in a buffer cylinder. Through a wireless connection, the energy meter (x2-tech) specifies the output the immersion heater can consume. The immersion heater sends all measurements (high limit safety cut-out, internal temperature and the values of the two external sensors) back to the energy meter.
