Emergency Power Supply provides the finest in backup
power supply units for the home and business.

Having started several years ago as a project to meet the needs of a homeowner whose basement flooded during outages because the backup sump pump could not keep up, we now have served thousands of customers throughout the U.S. and Canada with backup supply units for sump pumps, refrigerators, garage doors, fire doors, security doors, grills and gates, as well as providing systems for general use in the home or business for lights, lamps, computer, TV and much more:

We offer the EPS Sump Pump Guardian® and EPS Sump Pump Guardian PLUS®, effective, long lasting and easy to use backup power supply units that keep YOUR sump pump running at full capacity during a power outage.

Not only do they provide POWER ON DEMAND to operate your sump pump at full capacity, they are AUTOMATIC, requiring no maintenance or action on your part to perform its backup function.

There is no additional plumbing, ventilation or other construction needed to install the EPS Sump Pump Guardian® - just plug it into an outlet and plug your sump pump into one of the outlets on the EPS Sump Pump Guardian!

The EPS REFRIGERATOR GUARDIAN® is right now providing emergency power backup to refrigeration units in clinics, medical offices and pharmaceutical research facilities from New York to California, Vancouver to Nova Scotia as well as providing peace of mind to many homeowners. Feedback from our customers includes adulation at having preserved several thousands of dollars of vaccines during an outage and providing a supply of much appreciated ice during an outage.

No maintenance, no switch to flick, the EPS REFRIGERATOR GUARDIAN® provides immediate on demand power when your refrigerator freezer needs to operate. Strong 48v battery system provides 132 amp hours of stored power to power a clinical refrigerator when most needed!

EPS provides backup power for everything from commercial garage doors to Commercial/Industrial Doors and Security Systems, including parking gates, fire doors, and all types of security systems.

The EPS DOOR GUARDIANS provides backup for all types of access power needs, including parking gates, industrial or commercial doors, fire doors and security gates and systems. It comes in two versions: 20A capacity and 40A capacity, both of which will provide a high number of operations during a power outage.
