PV14-(xx) 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.
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 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
