Provides the best of both worlds

For those who want to enjoy the perks of living off-grid while still having the assurance of grid-power when necessary, this Radian 15-panel grid-assist system is for you.

Enjoy uninterrupted power

This system comes with a Fullriver battery bank which enables you to enjoy the uninterrupted power of an off-grid system. You can draw power from your battery bank first, then from the grid if necessary. If the grid goes down, the included solar panels will continue to charge your battery bank until grid power is restored.

Pre-wired for easy installation

This will deliver full power to your 120 and 240 VAC appliances and produce up to 603 kilowatt hours of electricity each month. The Four Star Solar pre-built Outback Radian GS4048A power center comes complete with two Outback FM80 Charge Controllers and MidNite Solar surge suppression. The pre-wired power center and included electrical diagram provide for a simple and painless installation.Back to Top Back to Top
