Operator and Maintenance Manual for the PRO-Verter S 3000
PRELIMINARY
PRO-Verter Circuits and Functions
A PRO-Verter is the central power management device (i.e., the “brain”) for a hybrid or high-
efficiency electrical system. At its core, the PRO-Verter has a combination inverter/charger, which
operates in concert with its supporting circuits to provide the operator with a multifaceted solution
and seamless power for an application:
Primary Circuits
• Inverter – Transforms DC from a battery to AC for use by a load
• Charger – Converts AC from generator or grid to DC for charging batteries
• Photovoltaic (PV) – Optimizes and regulates DC power from PV panels to charge batteries
Support Circuits
• DC Voltage – “Battery monitor” circuit
• AGS – “Automatic generator start/stop” circuit
Recovery Circuits
• AC-powered System recovery (overdischarged batteries)
• PV-mediated System recovery (overdischarged batteries)
NATO Circuit
• DC load or battery charging circuit
28 VDC Regulated Output Circuit
• Low-wattage, voltage-sensitive DC loads
Both the primary and the support circuit functions of the PRO-Verter are managed by native
programming, which can be adjusted via user interfaces.
If the PRO-Verter is connected to an overdischarged battery, the recovery circuit enables the PRO-
Verter to restore the battery to service using a 120 VAC power source such as a generator or grid/
utility. This circuit is not programmable and is an optional feature. Active PV panels may also be
used to recover a System with overdischarged batteries.
The NATO port allows connection of a NATO 24V DC circuit to the HPS’s 24 V bus. This can be in
support of a 24 VDC load or to allow charging from an external 24 VDC source.
