100A 96V MPPT Solar Charge Controller with 11.2kW PV Input and RS485

1. High-Power 96V Solar Charging

The KU-OG-06-002 is a 100 A MPPT solar charge controller developed for compatible 96 V battery-storage systems. It supports photovoltaic input power up to 11200 W, a 130–300 V MPPT range and maximum conversion efficiency of 98% for medium- and large-scale off-grid solar projects.

2. High-Voltage PV Input Management

• 11200 W Maximum PV Input: Supports compatible high-power photovoltaic arrays.
• 130–300 V MPPT Range: Tracks the array’s maximum power point across a broad high-voltage input range.
• 180 V Recommended PV Voltage: Provides a reference operating voltage for compatible 96 V system design.
• 300 V Maximum PV Open-Circuit Voltage: Defines the upper voltage limit for photovoltaic array selection.
• Dynamic Startup Voltage: Requires the photovoltaic input to reach approximately 20 V above the actual battery voltage before operation begins.

3. Intelligent Battery Charging

• 100 A Rated Charging Current: Supports high-current charging of compatible 96 V battery banks.
• Three-Stage Charging: Uses MPPT constant-current, equalization/constant-voltage and float-charging stages.
• Multi-Chemistry Compatibility: Supports sealed lead-acid, gel, flooded lead-acid, lithium iron phosphate and ternary lithium batteries.
• Custom Charging Parameters: Allows charging settings to be adjusted for other compatible battery types.
• Temperature Compensation: Supports charging adjustment according to battery and operating temperature conditions.

4. Wall-Mounted Industrial Construction

• External Wall-Mounted Design: Supports organized installation in solar equipment rooms and protected electrical areas.
• Temperature-Controlled Forced-Air Cooling: Adjusts fan speed according to the controller’s operating temperature.
• LCD and LED Display: Provides real-time operating data, system status and parameter adjustment.
• IP21 Enclosure: Intended for dry, protected indoor installation environments.

5. Communication and System Expansion

• RS485 Interface: Supports connection to compatible monitoring platforms and energy-management systems.
• Integration Protocol: Facilitates system integration, centralized operation and secondary development.
• Local Computer Monitoring: Supports compatible host-computer software for on-site system management.
• Optional WiFi Monitoring: Enables cloud access and mobile-app monitoring when the expansion module is installed.
• Parallel Operation: Multiple compatible controllers can be configured to expand total photovoltaic system capacity.

6. Electrical Protection

• Input Voltage Protection: Includes photovoltaic input undervoltage and overvoltage protection.
• Short-Circuit Protection: Helps protect the controller during abnormal output conditions.
• Temperature Protection: Responds when the internal operating temperature exceeds the configured limit.
• Charging Current Limiting: Prevents the charging current from exceeding the controller’s rated maximum
