Our verdict
A modular home-backup system, not a portable unit — the AC500 has no internal battery at all until you add B300K packs.
Best for: Serious home-backup builds where you're designing a system, not buying an appliance.
What we like
- 10000W surge is the highest here
- 5000W continuous handles whole-home loads
- 3000W solar input
Where it falls short
- Requires separate battery packs to function at all — budget accordingly
- Total system cost climbs fast
