Samlex Flush Mount Solar Charge Controller w/LCD Display - 30A

The Samlex Flush Mount Solar Charge Controller with LCD Display – 30A is a pulse-width modulated (PWM) charging regulator designed to protect marine batteries from overcharging while maximizing energy harvest from solar panels. With a 30-amp rated capacity, this controller is well-suited for boats, RVs, and remote marine installations where reliable battery management is critical to system uptime and battery longevity.

This Samlex charge controller features a four-stage charging algorithm with eight selectable settings to accommodate most battery chemistries—lithium, AGM, gel, flooded, and more. The LCD digital display provides real-time monitoring of charging voltage, amperage, and system status, eliminating guesswork about charge progress. LED status indicators offer quick visual feedback, while optional battery temperature sensor compatibility (via the DC-BTS-A-C accessory) enables temperature-compensated charging for optimal battery health in varying climates. The flush-mount design integrates cleanly into cabin walls or deck boxes without taking up valuable space.

Serious cruisers, fishing boat operators, and liveaboard sailors depend on solar charge controllers to extend battery life and reduce reliance on generator run time. The 30-amp capacity handles two to four typical 100-watt marine solar panels, making it ideal for vessels with moderate power budgets. PWM regulation is the industry standard for marine systems because it efficiently transfers solar energy without the complexity of MPPT algorithms, translating to lower cost and straightforward installation. Whether you're powering cabin electronics, navigation systems, or refrigeration, this Samlex unit provides the controlled, monitored charging that keeps offshore systems running reliably.
