NETCCA ® technology groupheadquartered in key national high-tech industrial development zone, China - founded geely industrial park, foshan city, guangdong province.Business in China mainland and Taiwan, the United States, Germany, Italy, Russia, Japan, Brazil, India, Korea, South Korea, South Africa, Australia, more than 60 countries such as Iraq and the Middle East region.Mainly engaged in UPS power supply, the elevator power supply, power supply, home inverter, solar inverter, voltage regulator, LED lights, lithium batteries and other products sales, processing, design and processing business and in 2009 to undertake 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
