FAQ

1. What is an off-grid inverter?

+

An off-grid inverter means that it works alone and cannot work with the grid. The off-grid solar inverter draws energy from the battery, transforms it from DC to AC, and outputs it as AC.
2. Can off-grid inverter work without battery?

+

Yes, it’s possible to use a solar panel and inverter without a battery. In this setup, the solar panel converts sunlight into DC electricity, which the inverter then converts into AC electricity for immediate use or to feed into the grid.

However, without a battery, you can’t store excess electricity. This means that when sunlight is insufficient or absent, the system won’t provide power, and direct use of the system may lead to power interruptions if sunlight fluctuates.
3. What is the difference between hybrid and off-grid inverter?

+

Hybrid inverters combine the functionalities of both solar and battery inverters. Off-grid inverters are designed to operate independently of the utility grid, typically used in remote areas where grid power is unavailable or unreliable. Here are the key differences:

Grid Connectivity: Hybrid inverters connect to the utility grid, while off-grid inverters operate independently.

Energy Storage: Hybrid inverters have built-in battery connections for storing energy, while off-grid inverters rely solely on battery storage without the grid.

Backup Power: Hybrid inverters draw backup power from the grid when solar and battery sources are insufficient, while off-grid inverters rely on batteries charged by solar panels.

System Integration: Hybrid systems transmit excess solar energy to the grid once the batteries are fully charged, while off-grid systems store excess energy in batteries, and when full, the solar panels must stop generating power.
