NETCCA ® Technology Group is headquartered in China's National Key high-tech Industrial Development Zone - Geely Industrial Park, Foshan City, Guangdong Province. Business in mainland China and more than 60 countries around the world. Mainly engaged in photovoltaic power supply, elevator power supply, energy storage power supply, home inverter, solar inverter, voltage regulator, LED lamp, lithium battery and other products sales, processing, design and processing business, and in 2009 to undertake global OEM, ODM business.



Microinverters convert power at individual photovoltaic (PV) panels and are usually rated at 400 Watt for single PV panels and up to 1.5 KW for multiple PV panels. Microinverters typically rely on two-stage power conversion. First of all, the DC-DC stage or booster converts variable DC voltage into a fixed DC voltage (typically 40 V to 60 V). At the same time, maximum power point tracking (MPPT) is used to maximize the energy harvested from the PV panels (typically FSW = 100 kHz).
First DC-DC stage or Booster, converts variable DC voltage into a fixed DC voltage (Typ. 40 V to 60 V), at the same time ensure maximum power been extracted from PV panel via MPPT (Maximum Power Point Tracking) technique, second, the DC-AC inverter stage converts DC into grid compatible 1Φ AC power. Contrary to String inverters, microinverters are attached to one, two or four PV-panels and perform MPPT tracking per PV-module sepa
