For GEL, AGM, and Flooded Lead‑Acid Batteries
Not for Lithium Batteries

Product Overview

The Flexcharge NC25A‑12 is an ultra‑high‑efficiency series regulator designed for solar, wind, and hydro (permanent magnet generator) charging systems from 0.1A to 25A. It includes a built‑in Charge Divert feature, allowing excess charging energy to be redirected to auxiliary loads or used to prevent wind turbine overspeed.

The NC25A can also be expanded to regulate 100A to 1000A+ charging sources and can charge multiple battery banks when used with standard battery isolators.

Industry‑Leading Efficiency

The NC25A holds a U.S. Patent for its innovative charging circuitry. While typical charge controllers operate around 96–97% efficiency, the NC25A achieves:

99.5% typical charging efficiency
99.9% peak efficiency
Only 4mA operating current

This means more of your solar/wind energy reaches your batteries instead of being wasted as heat. The NC25A effectively gives you the equivalent of an extra solar panel’s worth of recovered energy.

Dependability

Designed for remote, harsh, and mission‑critical environments, the NC25A includes:

Extensive transient voltage protection
High steady‑state voltage tolerance (unaffected by continuous input up to 100V)
Reverse polarity protection on battery connections
Fully sealed electronics for 100% humidity and marine environments
Install‑and‑Forget reliability

Simple to Operate

The NC25A includes:

Charge and Divert indicator LEDs
Peak charge voltage adjustment (13.8V–15.9V)
Easy‑access terminal strip for wiring

Monitoring equipment (voltmeters, ammeters) can be added externally if desired, but the controller itself is optimized for ultra‑low power consumption and long‑term reliability.
