Samlex Solar Panel Voltage Regulator

Samlex Solar Panel Voltage Regulators: Precision Charging for Every Application

When solar energy meets battery storage, the voltage regulator — commonly called a solar charge controller — is the critical link that determines how well your system performs and how long your batteries last. Samlex has been engineering power conversion solutions since 1991, and their solar charge controllers reflect decades of refinement built around one principle: precise, reliable regulation under real-world conditions.

What Samlex Brings to Solar Voltage Regulation

Samlex solar charge controllers regulate incoming solar power to protect your batteries and prevent overcharging. Rather than offering a single one-size-fits-all solution, Samlex provides a wide range of controllers from 6A to 40A capacity, with options spanning multi-stage, MPPT, and PWM controller types with series or shunt regulation, and displays ranging from simple LED indicators to bar graphs and multi-function LCD readouts.

Take the SCC-30AB as a prime example of Samlex's engineering approach. The SCC-30AB is a Series Type PWM Solar Charge Controller based on an advanced design using a microcontroller for digital accuracy and fully automatic operation, usable for 12V or 24V systems, with PWM battery charging optimized for longer battery life. It supports 30 amps of continuous charging capacity — enabling up to 360 watts for 12-volt panels or 720 watts of 24-volt panels — using a Series Mode PWM design for low-loss, higher-efficiency charging, and features four stages of charging (Bulk, Absorption, Float, and Equalization) for 100% return of capacity.

The MSK-20A is another standout in the lineup. The MSK-20A is a 3-stage intelligent Series Type PWM Charge Controller based on an advanced design using a microcontroller for digital accuracy and fully automatic operation, compatible with both 12V and 24V battery systems.

Built for RV, Marine, and Off-Grid Environments

Samlex solar charge controllers are used in conjunction with photovoltaic (PV) panels for uses such as automotive battery maintenance, RV applications, marine uses, and off-the-grid home battery storage systems. This broad application range is no accident — Samlex products are certified to industry standards and are field-proven for exceptional performance under the most extreme conditions.

Samlex solar charge controllers combine seamlessly with Samlex solar panels for a complete off-grid energy system. Whether you're maintaining a marine battery on a seasonal vessel or running a full off-grid cabin setup, the right charge controller is the foundation of an efficient, long-lasting solar installation.
