Description
Flexcharge PV7D 7A 12V Marine/RV charge controller for dual battery banks
The PV7 (Single battery banks) and PV7D (Dual battery banks) are cost effective shunting regulators designed for smaller 6V, 12V, or 24V Solar Only applications with a maximum solar charging current of 7A. Special order 6V or 24V units. These controllers are easily expandable to handle charging currents from 30 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 or Gel battery technologies. Like the NC25A they also uses only 4mA to operate the circuitry. The PV7 & Pv7D controllers are not for use with outboard motors.
The PV7(D) are 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. No heat sink is required on the PV7 because small amount of heat that is generated in the high efficiency solid state components. See the PV7 Charging Efficiency Graphs located at this link
Dependability
We took great care to design the PV7(D) 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 PV7(D) is designed for Install and Forget operation.
Simple to Use
The PV7(D) 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 four wire pigtails, either by soldering or on to 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 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.
