What is a photovoltaic inverter?
A photovoltaic inverter like 2000w pure sine wave inverter or 3000w inverter, is an important component of any home solar power system, used to convert direct current (DC) power from photovoltaic panels into alternating current (AC) power, similar to standard grid power.
How efficient are PV inverters?
The new generation of PV inverters are becoming more efficient, with efficiencies greater than 97% . The efficiency is brought about by changing the topology of the power converter or control scheme or by better circuit board layout techniques.
What factors affect the inverter lifespan?
It is generally believed that the main culprits that affect electronic components are high temperature, dust, oxidation, moisture, etc. Therefore, the inverter lifespan is also affected by these factors, which requires operators to perform necessary maintenance to extend their inverter lifespan.
