At those powers, yes. 48V or 400V.I'm curious is 48V is the way to go for an apartment backup system. I live in an area susceptible to power outages. I would need to power up 2 Frig/freezers-Full size, 1-Microwave, 2-Portable AC Units, Mics Computers/Phones. If this a good recommendation, then getting an all-in-one unit is what I would be interested in. My next question then is 3000W or 5000W? Which is best for my needs. Thanks in advance for any guidance.
