Morningstar Sunsaver SS-20L-24V

Morningstar SunSafer SS-20L-24V is a robust PWM charge controller designed for industrial applications. Morningstar now offers the third generation of its advanced SunSaver products. Since its launch in 1996, over 1 million SunSaver controllers have been sold in 73 countries. These controllers are utilized in photovoltaic systems for applications such as oil and gas production facilities, telecommunications and metering systems, marine equipment, and remote residential homes. Many performance features from the proven older models, such as ratings, dimensions, and the practical user interface, have been retained. Additionally, the following advanced features have been added:

• Full electrical protection
• 4-stage battery charging
• Self-diagnostics to detect critical faults
• Multi-colour status LED
• 3 LEDs to indicate battery charge level
• Recovery function for exhausted battery
• Telecom mode for sensitive loads
• Limitation of maximum charge for sensitive loads
• Protective cover for terminals
• Other certifications
