Abstract

IIn Slovenia net-metering on a yearly basis is massively used for connection of the photovoltaic (PV) plants into distribution network. Even more subsidies are given from the state for those who at the same time switch from oil, gas or wood heating to heating with the heat-pump (HP) systems. HPs are practically always air-to-water types (with single-phase compressor motors) meaning that when heat is needed the most, they switch on their resistive back-up heaters to cope with the demand. Power quality measurements were made at a single-family house with the 7 kW PV and 9,6 kWe HP systems installed in an urban environment. In this paper harmonic current problems of the PV system and current unbalance issues of the HP system are analysed.
