House UPS System
3000VA 120VAC


Our House UPS systems fill a market niche between portable generators and automatic standby generators.  Most power outages last less than a couple hours and these systems easily provide backup AC power for that length of time.  These systems are silent and fully automatic and transfer extremely fast when line power is lost.  No more guessing how long an outage will last and whether it is worth the trouble to drag out that portable generator.  For most outages which are short this system eliminates that trouble!

Or use this system with an automatic standby generator to continue to provide power while the generator is starting.

For details about how this system operates and its advantages click here.


What is included in the House UPS System?

We provide everything you need to install an operational system except for one circuit breaker that must be installed in your load center breaker panel and a connected wall outlet.  If you want to be able to provide backup power for a long-term power outage you will also need a portable or standby generator (not included).  System includes the following:

* UPS Module 
* Transfer Switch - 6 circuit (optional)
* short AC line cable
* battery charger (in UPS)
* AC Input Cord - 40' with NEMA L530P Plug (optional)
* AC Output Cord 10' with NEMA L530 Connector (optional)
* interconnecting battery jumper cables
* gel cell maintenance-free lead acid batteries (in UPS)
* external battery modules to extend run-time (optional)

We do not provide the circuit breaker for your load center panel due to the many brands of panels.  Purchase one locally that fits your panel.  It should be rated 30 amps.  Your installer will also need to wire this breaker to a 30A 120VAC NEMA L530R wall receptacle near the UPS.
