The current edition of pv magazine casts an eye over the Asia-Pacific solar markets, considering how cross-border interconnections can drive better resource efficiency, as well as the crucial role microgrids can play in the continuing roll-out of photovoltaics.

According to the manufacturer, the kit can also be used in combination with rooftop PV power, provided that the solar array provides a stable voltage to the heat pump. “As long as there is a stable voltage source that meets our heat pump requirements, then this kit is ready to use,” the spokesperson stated.

The monoblock heat pump is available in two versions with different leakage switches of 32 A and 40 A and a weight of 34 kg and 36 kg, respectively.
