Each component performs a different role in a power system:
- Inverter: Converts stored battery power into usable electricity for your home and manages charging
- Battery: Stores energy for use during power outages
- Solar Panels: Generate electricity from sunlight
Important clarification:
The inverter and battery are the core of the system. They are what provide backup power.
- The inverter can charge the battery directly from NEPA (grid supply)
- This means your system can function effectively without solar panels
Solar panels are optional.
They serve as an alternative charging source, helping to charge the batteries when there is little or no NEPA supply, and reducing electricity or fuel costs.
In summary:
- Inverter + Battery = Backup power
- Solar panels = Additional/alternative charging source
For best performance and reliability, all components must be properly matched.
