FQA:

1.Which inverter is the most efficient?
High quality sine wave inverters are rated at 90-95% efficiency. Lower quality modified sine wave inverters are less efficient - 75-85%. High frequency inverters are generally more efficient than low frequency inverters.

2.What happens to solar inverters?
Capacitor wear

Electromechanical wear of capacitors is the number one cause of inverter failure. Inverters rely on capacitors to provide smooth power output at different current levels; however, electrolytic condensers have a shorter lifespan and age faster than dry components.

3.Can I use a solar inverter without a solar panel?
Yes. You can connect a regular inverter without solar cells. However, you need to choose the right size inverter.

4.Do solar inverters require maintenance?
Unlike a boiler, your solar panels do not require annual maintenance to work efficiently. You don't need to pay extra for maintenance packages to keep them running well.
