Description
Flexcharge PV14 12v 14A Charge Controller for Photovoltaic Charging Systems
The PV14 is a cost effective shunting regulator designed for smaller 6V, 12V, or 24V Solar Only applications with a maximum solar charging current of 14A. Special order 6V or 24V units. The PV14 controller is easily expandable to handle charging currents up to 500A. We engineered this controller to be extremely efficient, accurate, and small (3" x 4.75"). It is Ideal for use in a marine environment. Use with Lead Acid or Gel battery technologies. Like the NC25A it also uses only 4mA to operate its circuitry. This controller is not for use with outboard motors.
Efficiency
The PV14 is an all solid state design using the highest efficiency components. All shunting type regulators must use a blocking diode in the charging path to block the battery voltage when the controller is regulating. The heat sink on the PV14 is used to dissipate the heat generated by the high efficiency blocking diode in the PV14.
We took great care to design the PV14 for long term operation in unattended locations; extensive transient voltage protection; high steady state voltage protection (it is not affected by continuous charging input voltages up to 50V, the point where the transient voltage protection activates); fully sealed electronics for 100% humidity operation; etc... The PV14 is designed for Install and Forget operation.
Simple to Operate
The PV14 includes an easy to read Charge Indicator. The peak charge voltage is factory set so there are no user adjustments to contend with. System wire connections are made by connecting to the controllers wire pigtails either by soldering or via a terminal strip.
Easy Upgrades
Upgrading the controller to regulate form 30 up to 500 amperes can be accomplished easily and is relatively inexpensive. Contact Flexcharge for details.
Energy State Taper Charge Process
This is the charging process used by all Flexcharge controllers. It has many benefits including greatly reduced gassing during charging and it allows for micro equalization of Lead acid as well as Gel battery technologies. Click on the link for more details.
