Shenzhen Growatt New Energy Co., Ltd.

Shenzhen Growatt New Energy Co., Ltd. was established in March 2019. It is a national company focusing on the research and development, production, sales and service of new energy equipment such as solar inverters, energy storage inverters and their monitoring systems. high-tech enterprises. The company has always been committed to being a new energy solution provider and serving all mankind.
Inverters are also called power regulators. According to the use of inverters in photovoltaic power generation systems, they can be divided into two types: independent power supply and grid-connected. An inverter is a power regulating device composed of semiconductor devices, mainly used to convert DC power into AC power. It is generally composed of a boost circuit and an inverter bridge circuit. The boost circuit boosts the DC voltage of the solar cell to the DC voltage required for inverter output control, and the inverter bridge circuit equivalently converts the boosted DC voltage into an AC voltage of common frequency. Speaking of which, the editor of Shenzhen photovoltaic inverter supplier takes us to understand the installation precautions and maintenance of photovoltaic inverters.
Before installation, you should first check whether the photovoltaic inverter has been damaged during transportation.
When selecting an installation site, you should ensure that there is no interference from any other power electronic equipment in the surrounding area.
Be sure to cover the PV panels with opaque material or disconnect the DC side circuit breaker before making electrical connections. When exposed to sunlight, photovoltaic arrays will generate dangerous voltages.
Cables used in photovoltaic power generation systems must be firmly connected, well insulated and of appropriate specifications. All electrical installations must meet local and national electrical standards.
The inverter can only be connected to the grid after obtaining permission from the local power department and having all electrical connections completed by professional technicians.
Before performing any maintenance work, you should first disconnect the electrical connection between the inverter and the grid, then disconnect the DC side electrical connection and wait for at least 10 minutes until the internal components are discharged before proceeding with maintenance work.
Any fault that affects the safety performance of the inverter must be eliminated immediately before turning on the inverter again to avoid unnecessary circuit board contact.
Follow the electrostatic protection regulations and wear an anti-static bracelet.
Pay attention to the hot surface of the inverter. For example, the radiator of power semiconductors will still maintain a high temperature for a period of time after the inverter is powered off.
All installation operations must be completed by professional technicians only.
The above information is provided by Growatt, a Guangdong photovoltaic inverter company. I hope it will be helpful to everyone. Shenzhen Growatt New Energy Co., Ltd. combines many years of production practical experience, based on high quality and market Demand-oriented, it has won the recognition and support of customers at home and abroad.
