Because these systems are designed to shut off automatically when the grid goes down to prevent energy from flowing back into the grid and potentially causing safety hazards for utility workers.

If you have a battery backup system or a hybrid solar generator system that combines solar power, with other energy sources such as a backup generator or the utility grid, then you can still have power during a power outage. In this case, the solar panels will continue to generate electricity, which is stored in the battery bank or used to power critical loads directly.

Battery backup systems or hybrid solar generator systems can be more expensive than traditional grid-tied systems. However, they provide the added benefit of backup power during outages, which can be especially important in areas with frequent power disruptions or for households reliant on medical equipment or other critical loads.

Does a solar generator need a battery?

Yes, a solar generator typically needs a battery to store the electricity generated by the solar panels for later use. Without a battery, the solar generator would only be able to provide power when the sun is shining and the solar panels are producing electricity. The battery bank in the solar generator provides a way to store the excess energy generated during the day for use at night or during periods of low sunlight.

The battery bank in a solar generator is typically made up of several deep-cycle batteries that are designed to handle the charge and discharge cycles of a solar generator. 

The size and type of battery bank required will depend on the energy needs and usage habits of the user, as well as the capacity of the solar panels and power inverter. A professional solar installer can help assess your energy needs and recommend the best battery bank for your solar generator.
