What are the specific requirements for on grid inverters?

1. on grid inverters require high efficiency. Due to the high price of using solar cells, we use on grid inverters in order to maximize the use of solar cells and improve system efficiency, we must try our best to improve the efficiency of on grid inverters.

2. on grid inverters require high reliability. Photovoltaic power generation systems have been mainly used in remote areas and country sides. Many power stations are unattended and maintained. This requires on grid inverters to have a reasonable circuit structure, strict component selection, and on grid inverters with various protection functions, such as input DC polarity reverse protection.

How about the technological development of photovoltaic on grid inverter accessories?

The development of photovoltaic on grid inverters has overcome the shortcomings of counter-switching. The power transistors set the output pulse width, and the effective value of their output voltage also changes accordingly. Because there is a free loop in the circuit of the photovoltaic on grid inverter, even if there is an inductive load, the wavelength of the output voltage will not be distorted. Photovoltaic on grid inverters have certain shortcomings, which are reflected in that the power transistors of the upper bridge branch and the lower bridge branch do not share quality, so control switches or isolated power supplies must be used. In order to prevent the joint control of the upper and lower branches of the bridge, a circuit should also be designed for opening and closing when the photovoltaic on grid inverter d is used. At the same time, the dead time must be set when using the photovoltaic on grid inverter, and the circuit structure is more complicated.

What are the precautions for using on grid inverters accessories?

1. Before installing the on grid inverters, first check whether the inverter is damaged during transportation.

2. When selecting the installation site of the on grid inverters, it should be ensured that there is no interference from any other power electronic equipment in the surrounding area.

3. Before making the electrical connection of the on grid inverters, be sure to use opaque materials to cover the photovoltaic panels or disconnect the DC side circuit breaker. on grid inverters can exposure to sunlight, and photovoltaic arrays can generate dangerous voltages.

4. The installation and operation of all on grid inverters must be completed by professional and technical personnel only.

5. The cables which has been used in the photovoltaic on grid inverters system must be firmly connected,when the on grid inverters well insulated, we will have appropriate specifications.

6. All on grid inverters installations must meet local and national electrical standards.

on grid inverters have been widely used in daily life and industrial production. Shenzhen Sumry Electronics Co., Ltd. can provide the best on grid inverters for their customers.
