Prosine 2.5/3.0 Installation & Operation Guide 1
Section 1: Features
Congratulations on your purchase of the Prosine inverter/charger. The Prosine inverter/charger uses
advanced high-frequency switching technology in the power conversion process. The circuits are
similar to those used in power supplies for computers and other modern electronic equipment. This
technology offers several benefits:
•
Light weight: for easy installation
•
Quiet operation: no transformer buzz
•
Clean DC output: filtered output for ideal battery charging
•
High surge capability: for hard-to-start AC loads
All Prosine inverter/chargers are approved for general use including residential, recreational vehicle,
marine, and photovoltaic applications based upon Canadian Standards Association (CSA),
Underwriter Laboratories (UL), and other regulatory agency standards. Prosine inverter/chargers meet
the stringent requirements of CSA 107.1 “General Use Power Supplies,” UL 458 “Power
Converters/Inverters and Power Converter/Inverter Systems for Land Vehicles and Marine Crafts,”
UL1741 “Power Conditioning Units for Use in Residential Photovoltaic Systems,” and other
standards.
Battery Charger Features
Dead Battery Charging Starts recharging batteries even if the battery voltage is near zero.
Power Factor Correction High power factor charging results in faster battery charging because
lower AC current is required from your generator or shorepower. When the AC source has limited
capacity, the charger leaves more current available for other AC loads on the circuit. On a 15-ampere
shorepower circuit, a Prosine charger delivers as much as 100 amps of DC current to the battery, while
non power-factor-corrected chargers typically can deliver only about 70 amps.
Automatic Three-Stage Charging Whenever AC power is supplied to the Prosine inverter/charger,
the “smart” charging capability of the Prosine provides a three-stage charge to quickly bring back
deep-cycle batteries to their full charge. Using microprocessor control, the Prosine precisely regulates
the voltage and current delivered to the battery, accurately charging the battery without risk of
overcharging and battery damage. Depleted batteries are taken through the recommended “Bulk”,
“Absorption”, and “Float” stages. The charging algorithm used in the Prosine inverter/charger is based
on the same charge cycle algorithm used in Xantrex’s proven Truecharge battery charger line.
Manual Equalization Charging The Prosine inverter/charger enables you to initiate an equalization
charge to optimize your battery capacity and rejuvenate your batteries. Equalization (for flooded
batteries only) helps reduce sulfation and extends battery life.
Battery Temperature Sensor Since battery temperature is a key factor in correct charging, the
charging formula must be adjusted (automatically and in real time) according to the actual battery
temperature to ensure that batteries are fully, but not over charged. For this reason, Xantrex has
included a battery temperature sensor with your Prosine inverter/charger and has temperature-
compensated the charge algorithm.
