What Safety Issues Should Not be Overlooked When Using Solar Inverters?
Know about solar inverter
An inverter, also known as a power conditioner or power regulator, is an essential part of a photovoltaic (PV) system. The main function solar inverter solutions is to convert the direct current (DC) generated by solar panels into alternating current (AC) for household appliances. All the electricity generated by the solar panels must go through the inverter before it can be used by the end user. Through the full-bridge circuit, the SPWM processor is generally used for modulation, filtering and boosting to obtain sinusoidal AC power matching the lighting load frequency, rated voltage, etc. for system end-users. With an inverter, DC batteries can be used to provide AC power to appliances. Proper use of a solar inverter greatly extends its service life and enhances safety. These issues cannot be ignored when using a solar inverter.
Safety issues in using solar inverter
The voltage must be the same when using a solar inverter. Each inverter has a DC voltage value for connection, such as 12 volts and 24 volts. Therefore, the voltage of the battery must be the same as the DC voltage of the inverter. For example, if your battery is 12 volts, you must use a 12-volt inverter to use it properly.
The positive and negative poles of the solar inverter must not be connected incorrectly. The DC voltage connected by the solar inverter is usually marked with positive and negative poles, with red indicating positive and black indicating negative, and the battery is also marked with positive and negative poles, with red indicating positive and black indicating negative. The wire diameter of the connection cable should be thick enough, and the length of the connecting line should be reduced.
The output power must be greater than the power used by the load equipment. Pay attention to appliances with large power consumption, such as refrigerators and air conditioners, when starting up.
The solar inverter should be stored in a ventilated and dry place, protected from rain, and keep a distance of more than 20cm away from nearby items and avoid flammable and explosive materials.
For safety and performance considerations, the following conditions should be met when installing a solar inverter: dry: cannot be submerged or exposed to rain. Cool: the temperature should be maintained at around 0℃ and 40℃. Ventilated: no foreign objects within 5cm on the casing and good ventilation on the end face.
When connecting the battery, please make sure that there are no metal objects in your hands to prevent short circuits or burns to the body.
Charging and inverting cannot be done at the same time. That is, the charging plug cannot be inserted into the output circuit of the inverter.
To prevent accidents, customers are not allowed to open the chassis for operation.
