If you have a big EcoFlow battery, you’ve probably been making great use of it during your travels. You’ve probably even have some EcoFlow solar panels to charge it with unlimited free energy—perhaps some flexible panels mounted to the roof of your RV. But the rest of the year, they sit idle. What a waste! If only there were some way to make use of these panels to feed your home electrical system in the day, store any excess in the battery, and discharge that to your home overnight, saving you hundreds of dollars a year on your power bill. That sort of system would pay for itself in a few years.
