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 Tape Charging Charging Algorithm Explained. 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. Features Cost Effective charge controller for Photovoltaic charging sources. Reverse polarity protected (Must have proper Fuse installed) Precision Auto assembled using proven Surface Mount Technology Sealed / potted electronics for use in high humidity and salt air environments. High efficiency components allows packaging in a very small enclosure. Safely Micro Equalizes Wet Cell Lead Acid and Sealed Gel battery technologies using the Energy State Taper Charge Process. ·Charging Algorithm Explained Expands easily into a high amperage controller. Up to 500A charging capacity with a charging efficiency increase to 99.95%. ·Expansion Kits All Solid State Design for extra long life and dependability. Factory Calibrated for charging lead acid Flooded cell, AGM, and GEL battery technologies. No user adjustments. Do not use on Lithium batteries Full 2 year repair or replacement warranty. Charging Indicator displays when the controller is passing charging current to the battery. Controller's circuitry eliminates back flow of current into solar panels during non charging periods.
Flexchargecontrollers are the controllers of choice for research projects around the world as well as solar systems on cabins, boats, and commercial projects. Sensitive data recording equipment is not affected by the Flexcharge Controllers because there is no EMI / RFI generated in the controller as is common on many others. Extremely high efficiency was a design goal for all Flexcharge controls. Little or no heat is dissipated from the controllers so all of the generated energy can be used. No matter if your system is a simple battery maintenance system or a large main power source, you will benefit from the efficiency and dependability of our products
