FLEXCHARGE Solar & Wind Charge Controllers

Ultra -High Efficiency Solar & Wind Charge Controllers

Waterproof and better than 99.5% efficient with charging currents of 0.5 to 25 amps, a 2-15% gain over competitors. Handles spikes up to 1,500V/A, so your controller won't be damaged by surges.

7 amp PV7D is a cost effective shunting regulator for smaller 6V, 12V or 24V solar only applications, expandable to handle charging currents from 30 to 500A. Works on single or dual battery bank systems and uses the FlexCharge Energy State Taper Charge Method for high efficiency, giving a full charge without gassing on 12V system with gel, AGM and flooded battery types. Reverse polarity protected and fully sealed for use in high humidity environments. Green LED indicator.

25 amp NC25A is a series regulator designed for alternative energy charging systems ranging from .1A to 25A. Ideal for solar (PV) and permanent magnet generators including outboard motors and smaller wind generators. Includes a charge divert feature for using excess charging source energy for other tasks, or for placing a load on permanent magnet charging sources such as wind generators to prevent over speed conditions. Draw: 5mA. Expandable up to 100A using an optional contactor. Green LED shows when panels are producing charge current and Red/Green LED display shows charging, divert and low battery levels.

      Comments about Flexcharge Solar & Wind Charge Controllers:

      I have had this controller for about 10 years and it simply gets on with the job with no worries. It controlls 2x90 watt Solar Panels and a wind generator on my 35ft Catamaran. I have 3 Battery banks and always have fully charged batteries including running the fridge 24/7. Pressuer water and LED lights everywhere. Never had any problems

      Comments about Solar & Wind Charge Controllers:

      Had 2 PV14s and 2 NC25s for several years.
      Both PV14s eventually drifted (lower) in their on @ off voltages. One now switches constantly because of minimal hysteresis (3-year @ 5-year life).
      Both NC25s need occasional readjustment to switch off at 14.1V. One NC25 melted in a Baja summer when used to control 2 parallel 135W panels (max output ~20A).

        With two batteries and one solar panel, I needed this product on longer trips. The PV7D allows me to sail longer before having to start the engine to recharge the batteries.

        • Waterproof

        Cons

          Best Uses

          Comments about Solar & Wind Charge Controllers:

          Researched a few of the controllers around and this seemed one of the best. Great service and support from the Flexcharge website and all my queries were answered quickly. Installed simply and is now keeping my batteries (an AGM and a wet-cell) topped up from my solar panel.

          Service and delivery comments:

          Still can't believe the speed and service you guys offer. Delivered to me on the other side of the world in less time and at a better price than my local boating supply chain can do!

            Comments about Solar & Wind Charge Controllers:

            The PV7D is the perfect solar controller for a vessel with separate house and start batteries. After having one for a year, the batteries are always topped up, virtually no water loss, and small size so can put anywhere. Simple, well designed, an on/off light, functional, easy to install.
