The Solar Mate SP600 is a high-voltage, transformer-isolated MPPT charge controller designed to efficiently convert solar energy into electricity for 48V lithium or lead-acid batteries. With a 600V open-circuit PV input and dual independent MPPT trackers, it maximises solar energy harvest while reducing system costs. Its high conversion efficiency (>97%), intelligent control features, and robust safety mechanisms make it an excellent choice for off-grid, hybrid, and energy storage applications.

Key functions:

1. High voltage & wide MPPT tracking: The 80-525V MPPT range minimises the need for a combiner box, reducing installation complexity and costs. With a 600V open-circuit PV input, it enables greater system flexibility and scalability.
2. Dual independent MPPT trackers: Designed for optimal solar energy utilisation, the SP600 supports two separate PV arrays, allowing installation on different roof orientations to maximise solar harvest.
3. High electrical safety & isolation: Featuring high-voltage reinforced insulation between the PV and battery, the SP600 ensures enhanced electrical safety and system reliability. Additionally, it includes built-in PV insulation resistance detection (earth fault detection) for improved protection.
4. Superior efficiency & compact design: With a maximum efficiency of over 97%, the SP600 minimises energy losses while maintaining high power density in a compact form, saving valuable installation space.

Additional intelligent features:

• Smart cooling system: Intelligent fan control minimises noise while optimising thermal management.
• User-friendly interface: LCD display + LED indicators provide real-time system insights.
• Advanced monitoring & communication: Equipped with RS485, CAN bus, and Bluetooth app support for seamless system monitoring and control.
• Programmable relay & dry contacts: Includes one programmable relay (dry output contact) and one dry input contact for customisable system integration.
• Parallel capability: Supports parallel connection of up to 15 units, enabling higher power capacity for large-scale installations.
• Battery compatibility & grounding: Works seamlessly with lead-acid and lithium batteries, with a CAN bus interface for lithium battery communication. The positive battery pole grounding feature meets telecommunication industry standards.

Versatile applications:

This high-performance charge controller is ideal for:

• Residential & commercial solar energy storage
