The principle of operation is relatively simple, the amount of energy produced that is not being consumed (surplus) is measured:

• Universally with a power meter (Meter)
• Obtaining the data through one of the power inverter compatible.

Once the surplus is obtained, it is diverted with a power control board (PWM / Dimmer) to a resistive load (such as a thermos to heat sanitary water, a stove or heat plate).

Due to the fact that the production surpluses are variable, the surplus measurement process and its subsequent derivation are carried out cyclically (continuously over time), thus obtaining a coordinated adjustment between the surpluses and the derived power.
