[RE-wrenches] Inverter for fire protection pump

[Joel Davidson]

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.
