Hybrid

A Hybrid System is a Solar Power System that you can install when you are still connected to the main Power Network, or PLN. Unlike an On Grid System, however, the Hybrid System has the capacity for power storage through battery utilization.

Essentially, this means that you will always have power, even if the main PLN system goes down. How long the back up power lasts will depend entirely upon how much storage capacity is available in the batteries you have installed.
