Flexcharge™ PV14-12 14A Charge Controller for Photovoltaic Charging Systems The PV14 is a cost effective shunting regulator designed for 12V Solar Only applications with a maximum solar charging current of 14A. The PV14 controller is easily expandable to handle charging currents up to 100A or more. 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 flooded, AGM, or Gel battery technologies. Do not use on Lithium batteries of any type. Like the NC25A it also uses only 4mA to operate its circuitry. This controller is not for use with outboard motors or any generator based charging system unless it is expanded. 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 components when the controller is shunting and the battery can no longer take any more charge. Dependability 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 40V, (the point after which 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 from 30 up to 500 amperes can be accomplished easily and is relatively inexpensive. Expansion Kits Contact Flexcharge for details. Charging Algorithm ExplainedThis 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. Features 100% Waterproof electronics for mounting in a marine environment. Uses Super High Efficiency Solid State Surface Mount Components. Oversize heat sink to keep the internal components cool . Circuit is machine assembled in the USA to ISO 9000 standards. Internal Precision Voltage Reference for high accuracy voltage regulation. Charging Indicator. 14 amp charging capacity for small to intermediate size solar arrays. Expandable to handle 35A, 60A or 100A of charging current, and multiple charging sources. Expansion Kits 35A, 60A, or 100A Charge Divert option. Consumes less than 5mA while charging and only 2.6mA at night. Built in Isolation prevents nighttime back flow of electricity from your batteries to the solar panel(s). Uses Energy State Taper charge algorithm for fast battery charging and super low battery electrolyte depletion. Looks for the full charged resting voltage of the battery to protect against overcharging. Charges a Zero Volt battery with full charge current. Most controllers will not charge a zero volt battery. No power wasting sample periods. Completely silent operation. UL listed encapsulation.
