DIY Battery Powered Backup Electric Generator Stationary or Portable SEE DESCRIPTION

View the step by step guide: http://www.instructables.com/id/How-t...

Be prepared for power outages with a standby battery powered generator. Build your own battery backup system for your home or business. A battery backup system allows you to power your essentials when the grid is down. Using sealed AGM deep cycle batteries, this system is safe for indoor use; you can install this system in your closet, in the corner of your office, or make it portable by using a cart.

By building your own battery backup system, you can size it to your desired needs. We will go over how to choose the right size battery and inverter, and how to put the system together.

You will need:

-1 or more sealed deep cycle batteries https://amzn.to/3BzJh2a

For this system I used the following:
-2 VMAX SLR155 12-Volt 155Ah AGM batteries connected in parallel (vmaxtanks.com)

-1 12V DC to AC 2000 Watt Inverter

-1 Vmaxtanks BC1220a 12V 20A 7-Stage smart charger

-1 Set of 2 gauge 6' 100% copper inverter cables (4Ga would have also worked, be sure to check the ratings of the inverter cables you buy)

-1 Pair of 4 Gauge 12" 100% copper link cables

**NOTE: Be careful when working with batteries and electricity. Do not short batteries. Use insulated tools. Follow all safety rules when working with electricity.**
