Which Type of UPS System Works Best with a Generator?

Which Type of UPS System Works Best with a Generator - Prostar


Do you have a generator to supply power during a lengthy blackout? You’ll get the most out of it if you connect your generator to a UPS system. But there’s more than one kind of UPS – it’s important to choose the right type of system so it will play nicely with your generator power.

A generator typically produces inconsistencies and fluctuations in voltage and frequency ranges. If the range is wider than what the UPS is willing to accept, your load will continue to run off the UPS and eventually deplete the batteries. This scenario would be typical with an off-line or line-interactive UPS system.

An on-line, double-conversion UPS system works differently and is the type of UPS we recommend for use with a generator. An on-line UPS continually converts incoming AC power – whether from the main power supply or a generator – into filtered DC power, and then reconverts it back into AC power with a pure sine wave. That’s the clean feed of power your sensitive equipment craves. And as another benefit, an on-line UPS filters variations in frequency as part of its everyday operation, so battery life doesn’t shorten prematurely.


When it Comes to Generator and UPS Compatibility, Size Does Matter

Your standby generator has to be large enough for any UPS – even an on-line system – to function properly. As your connected equipment cycles on and off, it can cause surges, spikes and sags that will make your UPS transfer the load to battery. To avoid this problem, make sure the generator you’re running has an unused capacity twice the kVA rating of the UPS system.


Don’t Forget About Grounding

If you pull the plug on your UPS to move it from the utility power supply to the generator, you’re also pulling the plug on the electrical grounding. A sudden loss of grounding on the UPS and all the equipment it powers could be a big problem: currents normally dissipated to ground through the UPS would find another path to get there, possibly through network cables, passing through other devices along the way.

Your in-house facilities manager or a local electrician should be consulted to make sure you have no safety or liability concerns. Your installation needs to maintain grounding, adhere to codes and minimize the chance of equipment damage, data loss and shock hazards.
