Features

Efficient Solar Charging

• Advanced 3-Stage PWM Charging: Boost, Float, and Equalization charging; Equalization helps prevent sulfation in lead-acid batteries (excluding GEL and lithium).
  
• Automatic Temperature Compensation: Automatically adjusts charging voltage based on ambient temperature (-3.0 mV/°C/2V; excludes lithium).

Flexible System Compatibility

• 12V/24V Auto Detection: Automatically detects 12V or 24V battery systems.
  
• Supports Multiple Battery Types: Compatible with Sealed, GEL, Flooded, and lithium batteries.
  
• 55V Max Solar Input Voltage: Supports solar panel configurations with up to 55V PV input.

Safe & Reliable Operation

• Five Operating Modes: Light Control (10-min Delay), Light Control + Timer Control (1–14 h), Manual, Debug, and Normal On.
  
• Electronic Protection: Protects against overcharge, over-discharge, overload, short circuit, and reverse polarity.
  
• TVS Lightning Protection: Helps protect the controller from lightning-induced voltage surges.
  
• UL 1741 Certified: Certified for trusted safety and reliable performance.
