Base Kit 3 Off-Grid 7.3kW Residential Solar Power System

Off Grid 7.3kW Solar Power System

This is the largest of our off grid solar power systems that altE has designed - just for you! Depending on your needs, we have a system to get your started.

How much power will I get from this system?

Base Components of this Off Grid System:

The solar panels and the pre-wired inverter/charge controller system and components are included in the base kit. Battery bank and Mounting solutions are options that you can add on.
