The zero feed-in control makes sure that the CHP unit does not feed electricity into the public mains. If the full load capacity of the CHP unit is higher than the current electricity demand on site, its power production is decreased to that level – even if the CHP unit’s heat production could be used.
This zero feed-in control can also be refitted in our CHP units in the field. It is advisable to think about ist when a feeding into the mains is not possible at cost-covering rates (any more) and / or forbidden by the mains operator.
