Grossman: They dominate the residential stationary backup power generation market with over a 75% share. But that standby backup power generation market is just 5% penetrated in the U.S., so there's a long runway for growth.
They're also viewed as a clean-energy source, since their generators are run by natural gas, often replacing diesel generators.
And several years ago they got into residential solar battery storage. They made acquisitions. Now they're one of the leading solar power management systems along with Tesla (TSLA). There's an even longer runway for growth on the solar home battery side. So we see 15% growth for them for some time.
