When your batteries get to their critical level and you don’t have a back up generator you will have 2 options:
- go without power to protect your batteries
- risk reducing the life of your batteries and continue using power
This choice normally needs to be made when you are using more power than normal. For example, when friends or family are staying and you want everything to run smoothly. If you want anxiety free power at any time, the only way to guarantee it is with a back up generator.
