Photovoltaic-Energy own consumption
You can ideally use available energy from your photovoltaic system (if installed) with your
OCHSNER heat pump. For this you need a switching contact of the photovoltaic system,
which gives the heat pump control OTE the signal "energy available”.
The heat pump can then use the available energy to heat up the buffer tank, the hot wa-
ter tank or the whole building in order to use this as an energy/heat store (the same holds
for cooling operation - charging possible at low temperatures). The thermal energy stor-
age has at present a far greater potential than electrical storage (accumulators). You can
thus optimise the energy consumption simply and thus significantly increase the efficien-
cy of the complete system.
1) Photovoltaic modules
4) Meter (current draw or feed)
2) Inverter (with switching contact)
5) Electrical consumers
3) Heat pump (with OTE control)
6) Public grid
