More power when you need it most.
The Evergrid is an affordable retrofit that keeps solar power flowing when the grid goes down. The Evergrid is a stand-alone appliance that lets a grid-tied inverter function through an outage. It provides enough surge capacity to run refrigerators, lights and air conditioning—all for thousands less than a battery backup system.
More power in a single box.
Maxout's Polyverter is the first true all-in-one hybrid inverter. Featuring Maxout's patented optimization, as well as backup, surge and load shifting, the patented Polyverter is 1/3 the cost of similar systems. With all the electronics in one ground-level box, installation is a snap, components stay cool, and your solar array puts out more power than ever.
More power from your solar array.
Maxout’s patented Balancer will keep solar power flowing when the sun, or even the grid, is down. The Balancer, which installs between a string inverter and PV panels, provides emergency backup, storage, time-of-use load-shifting, per-panel optimization, and monitoring. All for less than one-third the cost of other solutions.
