What is the meaning of on grid inverter?

The on grid inverter should not only convert the DC output from the solar photovoltaic power generation system into AC, but also control the voltage, current waveform, frequency, phase, and synchronization of AC, but also solve the problem of the power grid. Interference self-protection, separate operation and island effect, as well as maximum power tracking technical problems. This requires higher technical requirements for on grid inverter.

What is the International protection level certification (IPxx rating) of on grid inverter?

The protection level or IP number classification is for the product's protection against solid foreign objects (indicated in the first code of the protection level) and water (indicated in the second code of the protection level). The larger the number, the better the protection ability. The use of the NEMA enclosure type in the United States is similar to the international protection level. Most of the outdoor on grid inverters are IP45 (not dust-proof) or IP65 (dust-proof), or in the United States, they are NEMA 3R (no dust protection) or NEMA 4X (dust-proof, direct splash-proof, and additional Anti-corrosion protection).

What are the precautions for using on grid inverter accessories?

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

2. When selecting the installation site of the on grid inverter, 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 inverter, be sure to use opaque materials to cover the photovoltaic panels or disconnect the DC side circuit breaker. Exposure to sunlight, photovoltaic arrays will 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 used in the photovoltaic on grid inverter system must be firmly connected, well insulated, and have appropriate specifications.

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

Can the on grid inverter be directly connected to the battery for power supply?

Most on grid inverters require that the input DC voltage is too high, and common battery packs are no more than 72V or 96V, so there are very few gon grid inverters that can meet your requirements. As far as I know, there seems to be only one. The on grid inverter can only connect to the low-voltage battery pack to supply power to the grid. Your power generation method will be much more expensive than separate grid-connected power generation and separate off-grid power generation. Two sets of different types of on grid inverters are required respectively, and the power generation efficiency is slightly lower. Power grid outages will not be affected, but the installed capacity is required to be large enough.

The use of on grid inverter has greatly alleviated the difficult problem of power consumption in remote areas and has been welcomed by a large number of consumers. Shenzhen Sumry Electronics Co., Ltd. is committed to providing various on grid inverters with high quality for all customers from all over the world.
