A power cut in the office means lost work, dead phones, and a server that took six months to set up going offline. You don't need a generator in the car park. You need 3600W of clean, silent output that kicks in before your equipment even notices.
The Powertech S3 runs on a 3072Wh lithium pack and delivers 3600W continuous. That's enough to carry a small office — multiple monitors, a printer, a fridge, a router — through a multi-hour outage without breaking a sweat.
The UPS function is the one that matters. When mains drops, the S3 takes over in milliseconds. Your server doesn't see a blip. Your POS terminal keeps ringing. Nobody panics.
Mains, DC, cigarette socket, USB-A, and USB-C outputs cover every device on the desk. Solar, mains, or DC recharging means you can top it up overnight or from a panel on the roof.
Standby mode keeps idle draw minimal when it's sitting ready between outages.
Need more than 3072Wh? The Powertech expansion battery (MB4105) adds another 2048Wh. Sold separately.
