Let's face it, when the grid goes down your life slows to a crawl: 

  • No lights
  • No phone
  • No refrigeration
  • No computers
  • No home business

Stop getting left in the dark!

Simply install the Four Star 4,400 Backup Kit and you're ready to go when the utility grid is knocked out or unstable. Just decide which loads you want to run and you're back in business. Applications  This emergency Backup Power System is a must-have during hurricanes, tornadoes and other natural disasters!  If managed carefully, this system will run for days while powering up your:

  • Lighting
  • Cell phones
  • Well pump
  • Refrigerator
  • Internet
  • Security alarm

Not appropriate for: Air-conditioning, heating or agricultural irrigation pumps.

Seamless electrical coverage

This 240-volt backup power unit incorporates an inverter that monitors the grid for disruptions. When the grid goes down or is disconnected, the inverter switches to battery backup in less than a second, keeping your critical loads online until the grid comes back.  The battery banks of the Four Star Solar Backup 4,400 can be charged with grid electricity, or by generator, or by solar panels. They can also be expanded by adding additional batteries. See Battery Options below.

Add solar panels, qualify for the Federal Tax Credit

Easily add solar panels with our Solar Panel Add-on Options below. Adding solar panels expands the capacity of your backup power system and qualifies the whole purchase for a 30% federal tax credit. 

This is essentially a small offgrid power system with 240 VAC output. Read our Load Evaluation Worksheet to understand how to determine which critical loads you will be able to power. If you need to expand capacity you can add more solar panels and batteries, and those will qualify for an additional tax credit.

If you add the Solar Add On, your purchase of this backup power system will qualify for a Federal Tax Credit equal to 30% of the installed cost. Back to Top
