SYSTEM SETUP AND OPERATION GUDIE FOR THE 1 kW HYBRID POWER SYSTEM (HPS)
PRELIMINARY DRAFT
Theory of Operation
Models of Operation
Depending on the application, there are several operational models that can be configured using a
PRO-Verter:
DC-only/Inverter (automatic functions)
Operating conditions – All power generated is from DC sources and AC loads are supported by the
PRO-Verter’s Inverter function using energy stored in batteries.
Hybrid (automatic functions)
Operating conditions – The “Continuous Load” AC power requirement is LESS than the individual
Inverter or Generator/Grid AC power output ratings.
In the Hybrid model, the PRO-Verter serves as the primary power management device in a System,
using either Inverter AC power or Generator/Grid AC power to maintain the load. In the Hybrid
model, the batteries will cycle regularly to mitigate generator run-time and logistical support often
associated with operation in remote locations. Hybrid systems also provide the operator with a
flexible architecture that allows for the addition of multiple power sources, such as renewable power
generation.
Load Support (automatic functions)
Operating conditions – The “Surge Load” AC requirement is MORE than the Generator/Grid AC
output, but less than the Inverter AC output rating.
In the Load Support model, the Load Support model allows the use of a smaller generator based
on total loads operating over 24 hour period rather than a larger generator that is required for the
“peak” loads, which may only last for a brief period. The PRO-Verter can provide supplemental,
“surge” AC power (beyond what can be provided by a generator/grid AC source) during brief/
intermittent periods while allowing the “continuous” loads to be supported in the Hybrid model.
UPS (automatic functions)
Operating conditions – A PRO-Verter connects critical AC loads directly to grid/utility or prime AC
power when it is available, and provides backup power for the load by supplying Inverter AC (using
energy from a connected battery bank) when the Grid-Utility or Prime AC source is interrupted.
In the UPS model, “peak shaving” and the use of renewable power sources are also possible by
connecting a Power Hub.
Note about PRO-Verter model programming:
The PRO-Verter is usually pre-programmed at the factory for use in the application in which it is to
