PROTEK HOME BACKUP SYSTEMS

Protek 3kW Battery Backup System I

Add your own 24 Volt battery and the Protek backup system becomes the ideal system for powering household loads such as refrigerators, microwave ovens, power tools, lighting and small AC units during a short term power outage. It's perfect for areas prone to power outages. And since it's designed to accomodate the easy addition of solar panels, it's ideal for use in rural electrification projects, and situations where energy independence is desired, essentially anywhere where a reliable power source is needed but grid connection is not readily available or desirable.
