Huawei Grid Tie PV Inverters


Huawei Technologies Co., Ltd. is a Chinese based technology company founded in 1987 they're headquartered in Shenzhen, Guangdong.


It designs, develops, and sells telecommunications equipment and consumer electronics. It also provides grid-tie solar inverters from the range from 3kW to 100kW.


Huawei manufactures a range of products designed for solar photovoltaic solutions. These include the SUN2000 string inverter series, the iManager smart management system incorporating the Smart Logger, iManager NetEco 1000S and FusionSolar.


The SUN2000 is a transformer-less grid-tied photovoltaic inverter that converts high voltage DC power into sine wave 3-phase grid-frequency AC.


The absence of a transformer leads to higher efficiency, reductions in weight and size and a lower cost due to the reduced number of components.


The component parts of the SUN2000 series inverter system are located in a single aluminium cabinet with an integral heat sink.


The cabinet is IP65 rated for outdoor use which means the electronic components are protected against dust and water ingress which reduces the likelihood of damage to components. This is in line with industry standards.


Since 2015, Huawei is the top manufacturer of solar inverters in the world. Followed by Sungrom and SMA.




Huawei Zero Export Device


On-gird solar power (PV) plant generates excess power when the connected load is lesser than the power generated by the solar power plant (Power generation > Power required).


This excess power is synchronized with grid power hence it can revere the power flow.


In simple words, power will flow from the PV plant owner’s home to the connected grid [when Solar power generation > Power required by connected load].
