Kiss the Electric Company Goodbye
This large, totally off the grid, solar power system allows you to be your own electric company! This system is designed to power large off-grid homes with multiple computers, TV's, refrigerator/freezers, and no shortage of luxury appliances. It's also great for workshops, industrial studios or greenhouses. 

120/240 Volt, AC Power for your Off-grid Workshop
Fifty-four (54) American-made Suniva 285-watt solar panels and one MS4448PAE/3 Triple Power Center will give you all the power you need to run:

  • Table saws
  • Drills
  • Well pump
  • Lights
  • Fans
  • Appliances
  • And more!

True Sinewave Power
Clean sinewave power from the Magnum Energy inverters is the heart of this off-grid system. Your Power Center will convert the DC electricity produced by your solar panels into a clean form of AC electricity that is compatible even with sensitive electronics. 

Four Star Solar has assembled the three Magnum Energy MS4448PAE inverters, three charge controllers, and all the necessary safety components to create the Magnum Power Center. They have also pre-wired and tested the whole inverter system saving you time, money and eliminating the risk of “smoking” your inverters by installing them wrong.


120/240 Volt AC Power
This off grid solar system will deliver full power to 120 or 240-volt loads, and produce up to 2,017 kilowatt hours of electricity each month. Use our Off-grid Sizing Worksheet (PDF) to estimate your future power use. You can also call Wholesale Solar to customize any off-grid project you may have: 1-800-472-1142. We'll be happy to help you get started.
