I need to UPS a smart bakery oven (120v @ 14A) and related machinery (motors & computer control). I can make due with somewhere between 3kw - 4kw demand. I can size the battery storage as needed; that's not a problem. I can't find an appropriate inverter/charger.
I'd like an inverter/charger that charges via 240V but the output (inverter) is all 120V @ 60Hz, meaning the inverter is 100% carrying the load all the time.
Charging via 120V gets into circuit breaker issues at this load because when the grid power comes back on, the oven and other equipment is still running AND the batteries need charging resulting in more than 4kw demand at the load center after a power outage. High amperage circuit breakers for 240V are more available than what a load center can handle at 120V.
I want full sine wave because the machinery is all computer controlled.
