Description

technical field [0001] The present disclosure relates to the technical field of photovoltaic thermal storage, and in particular, to a photovoltaic thermal storage heating system and a method thereof. Background technique [0002] The existing thermal storage photovoltaic heating technology generally adopts the AC power supply mode of photovoltaic array + DC combiner box + inverter (mains supplementary); then the thermal storage heating equipment converts photovoltaic power into thermal energy storage through high specific heat capacity thermal storage materials, and then Released slowly for heating. In this power supply mode, the utility power is required as a backup power supply, which cannot fully utilize the peak-shaving and valley-filling effect of the heat storage and heating equipment; The system stops working due to lack of reserve power; if there is no mains power supply as a backup power supply, in bad weather such as rainy or snowy weather, the insufficient power ...
