·Description
PV inverter is the key equipment of photovoltaic power plant. The reliability,efficiency and safety of the PV inverter can directly affect the entire system, the power generation and the stable operation of the power plant. Plant SP series is designed for large and medium photovoltaic power plants. It is ideal for solar generation in communication, telecommunication, petroleum, oceanography, meteorology, and so on. It adopts low-frequency isolation transformer, with capacity from 50-250K. Multiple inverters can be run in parallel, simplifying power plant design. It can run continuously with full load at +55℃. The adoption of optical isolation improves the anti-interference ability. Optimized design of circuit and structure improve the thermal efficiency and the stability.It is your best choice.
Areas of Application: Transportation, telecommunication, petroleum, oceanography, meteorology and so on.
