Inverter for Solar Panel System
Tips: How to select a right solar inverter for PV system?
Solar inverter is an important conversion device of solar photovoltaic system, which can not only convert direct current energy into sinusoidal current synchronized with the frequency and phase of the power grid, but also feed the power into the grid. It can also protect the safety of the whole power station, so the selection of a good solar inverter plays an important role in the photovoltaic power station.
1. Efficiency
The efficiency represents the power loss of solar inverter. The efficiency of the inverter has an important impact on the photovoltaic power generation system to improve the effective power generation and reduce the cost of power generation. Therefore, the selection of solar inverter should be compared as far as possible and the products with higher overall efficiency should be selected.
2. Rated output power
The rated output power represents the power supply capacity of the solar inverter to the load. Solar inverter with high rated output power can carry more power load. When choosing solar inverter, we should first consider that it has enough rated power to meet the requirements of the equipment under the maximum load, as well as the expansion of the system and the access of some temporary loads.
3. Startup performance
The solar inverter should be started reliably under rated load. The high performance solar inverter can start at full load for many times without damaging the power switch and other circuits.
4. Output voltage adjustment performance
The adjustment performance of output voltage represents the voltage stabilizing ability of output voltage of solar inverter. Generally, photovoltaic inverter products give the percentage of fluctuation deviation of output voltage of the solar inverter when the dc input voltage changes in the allowable fluctuation range, which is usually called voltage adjustment rate.
