Morningstar Corporation Energy Controllers Editorial Review
The Morningstar Sunguard 6A Solar Charge Controller is a reliable and high-quality option for charging 12V batteries. It acts like a blocking diode, preventing energy flow from the batteries back to the panels. It is not suitable for charging two 12V batteries in series, as it is designed for a single 12V battery. The maximum voltage output of this unit is around 14.35 volts at temperatures between 0째F and 60째F. The compact and well-made design allows for easy installation and it is waterproof. Customers have praised its performance, durability, and user-friendly interface.
