Product Details

4.5A PWM CONTROLLER: Morningstar Sunguard Pulse Width Modulation (PWM) 4.5A solar charge controller delivers reliable charging for smaller solar systems. It regulates power from the solar array that it delivers to batteries. Benefit from its low self-consumption and high energy harvest. RUGGED DESIGN: Made with 100% solid-state components and epoxy encapsulation for exceptional durability. It is rated for 25% over currents without the need for derating. The controller is easy to install, featuring outdoor-rated, waterproof connecting wires that ensure a secure connection to the solar module and battery. EASY INSTALLATION: Easy to set-up, with a convenient test-button feature and LED indicator. The test button allows you to verify correct installation by turning the lights on during the day, while the LED indicates selected lighting option. Its rugged design is made to withstand harsh conditions including seaside environments. LONGER BATTERY LIFE: This controller uses series design PWM charging instead of shunt, offering more efficient battery management. It includes temperature compensation for optimized charging and low self-consumption, which extends battery lifespan and enhances overall performance. TRUSTED RELIABILITY: Morningstar Corporation is a US company established in 1993 and is a global leader in manufacturing PWM and MPPT solar charge controllers, inverters, and accessories.

Customers like the size and ease of installation of the product. They mention it's great for small vehicle/boat solar systems, easy to connect, and comes with clear instructions. Some are also satisfied with its waterproofing and temperature compensation. However, some customers differ on functionality, build quality, and value for money.
