Morningstar SunSaver SS-10L-24V: Professional 24V Management with Battery Safeguard

The Morningstar SunSaver SS-10L-24V is a rugged 10-amp PWM solar charge controller specifically engineered for 24V off-grid systems. Unlike the standard model, the "L" version includes an integrated Low Voltage Disconnect (LVD), which automatically shuts off DC loads when the battery reaches 23.0V. This essential feature protects your 24V battery bank from over-discharge, ensuring a longer service life and preventing costly system downtime in remote locations.

Designed for mission-critical industrial use, the SS-10L-24V features marine-grade epoxy encapsulation to protect the internal 32-bit microprocessor from salt air, humidity, and corrosive environments. It is a 100% solid-state unit with Class 1, Division 2 (C1D2) hazardous location certification, making it the preferred choice for oil and gas fields, telecommunications, and offshore monitoring.

High-Performance Industrial Features:

• Intelligent Battery Protection: The 24V LVD feature disconnects at 23.0V and reconnects at 25.2V, protecting AGM, Gel, and Flooded battery banks from permanent capacity loss.
• Extreme Environmental Hardening: Anodized aluminum enclosure and epoxy potting provide total resistance to corrosion, dust, and moisture ingress.
• Advanced 4-Stage PWM Charging: Precision Bulk, Absorption, Float, and Equalize stages (selectable for Sealed or Flooded batteries) maximize energy harvest and battery health.
• Hazardous Location Certification: UL/CSA Class 1, Division 2 (Groups A-D) approved for safe operation in environments where flammable vapors may be present.
• Temperature Compensation: Integrated sensor adjusts charging setpoints based on ambient temperature to prevent overcharging in summer and undercharging in winter.
• Unmatched Reliability: Field-proven design with a failure rate of less than 0.1%, trusted globally for over 25 years.

Technical Tip: When setting up a 24V system, ensure your solar panel configuration provides a Voc of less than 60V. For flooded batteries, simply remove the terminal jumper to enable the higher 28.8V equalization/absorption charge.
