Joel:
With these requirements, the inverter I recommend is a generator.

Wrenches,
Our customer has a fire protection pumping system that operates at 240VAC
and 22 amps with a 110 amps starting surge. The pump will only be used for
up to 4 hours in an emergency (but hopefully never). The customer wants an
inverter and battery (no generator or PV) in case grid power is destroyed
by fire. What inverter(s) do you recommend? Thank you very much for
sharing your off-grid knowledge.
Joel Davidson
