60A MPPT Solar Charge Controller for 12V/24V/48V Battery Systems with RS485
A 60 A MPPT solar charge controller for automatically detected 12 V, 24 V and 48 V battery systems. It supports multiple battery chemistries, three-stage charging, RS485 communication, configurable load control, parallel expansion and up to 3408 W of photovoltaic input on a 48 V system.
1. Automatic Multi-Voltage MPPT Control
The KU-OG-06-001 is a 60 A MPPT solar charge controller for compatible 12 V, 24 V and 48 V battery systems. It automatically identifies the connected system voltage and tracks the photovoltaic array’s maximum power point, providing conversion efficiency up to 97%.
2. System-Specific Photovoltaic Input
• 12 V Systems: Support 20–210 V DC photovoltaic open-circuit input and up to 852 W of PV power.
• 24 V Systems: Support 36–230 V DC photovoltaic open-circuit input and up to 1704 W of PV power.
• 48 V Systems: Support 70–230 V DC photovoltaic open-circuit input and up to 3408 W of PV power.
• Automatic MPPT Tracking: Adjusts the operating point according to changing sunlight and module conditions.
• PV Array Selection: The array voltage must remain within the corresponding controller limits under all expected operating temperatures.
3. Multi-Chemistry Battery Charging
• Three-Stage Charging: Uses MPPT constant-current, voltage-controlled/equalization and float-charging stages.
• Broad Battery 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: Adjusts relevant charging parameters according to temperature conditions.
• Charging Current Limiting: Prevents charging current from exceeding the controller’s rated limit.
4. Load and System Management
• 60 A Charge/Discharge Rating: Supports compatible battery charging and DC load-control applications.
• Multiple Load Modes: Provides normally on, normally off and dual-period timer control.
• Parallel Expansion: Multiple compatible controllers can be configured to increase total photovoltaic system capacity.
• LCD and LED Display: Shows operating status, system data and adjustable parameters.
• Wall-Mounted Installation: Supports organized installation in protected indoor equipment areas.
5. Communication and Remote Monitoring
• RS485 Communication: Supports connection to compatible monitoring and energy-management systems.
• Integration Protocol: Communication information can be used for centralized management and secondary system development.
• Local PC Monitoring: Supports online monitoring through compatible computer software.
• Optional WiFi Module: Enables mobile-app and cloud-based monitoring when the expansion module is installed.
6. Protection and Environmental Design
• Electrical Protection: Includes overcurrent, high-voltage, low-voltage, short-circuit and reverse-input protection.
• Temperature Protection: Helps protect the controller when its operating temperature exceeds the configured limit.
• IP21 Enclosure: Intended for dry, protected indoor installation environments.
• High-Altitude Operation: Supports installation up to 5500 m, with power derating required above 2000 m.
