Pros
- Runs 240 V loads such as a well pump alongside 120 V circuits
- 12,000 W surge for 20 seconds handles motor starts
- Switches to battery in 10 ms when the grid drops
- Cheapest way into a split-phase 48 V inverter-charger
Cons
- Needs a 240 V source to charge, so a 120 V-only generator won’t work
- No UL listing, so many inspectors won’t approve it
- 4,000 W is tight for 240 V pumps plus household loads at once
