Flexcharge™ PV7D

The PV7D (for Dual and Single battery banks) is a cost effective shunting regulator designed for smaller 12V Solar Only applications with a maximum solar charging current of 7A. Special order 6V or 24V single battery bank units. These controllers are easily expandable to handle charging currents from 35 to 500A. We have engineered these controllers to be extremely efficient, accurate, salt water spray resistant, and very small (1.5″ x 2″). It is Ideal for use in a marine environment. Use with Lead Acid AGM or Gel battery technologies. Like the NC25A, they also use only 4mA to operate the circuitry. The PV7D controllers are not to be used with outboard motors or any generator based charging system. For Lead Acid GEL, AGM, and Flooded cell Batteries. Do not use on Lithium batteries of any type.

Efficiency

The PV7D are a all solid state design using the highest efficiency components. No heat sink is required on the PV7 because almost no heat is generated in the high efficiency solid state components.

Dependability

We took great care to design the PV7D for long term unattended operation; extensive transient voltage protection; high steady state voltage protection (it is not affected by continuous charging input voltages up to 33V, the point where the transient voltage protection kicks in); fully sealed electronics for 100% humidity operation; etc… The PV7D is designed for Install and Forget operation.

Simple to Use

The PV7D includes an easy to read Charge Indicator. The peak charge voltage is factory set so there are no user adjustments to contend with working with all lead acid battery types. System wire connections are made by connecting to the controllers five wire pigtails, either by soldering or on a owner supplied terminal strip.

Easy Upgrades

Upgrading the controller to regulate many hundreds amperes can be accomplished easily and is relatively inexpensive. Contact Flexcharge for details.

Energy State Taper Charging

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.
