Description

The SMK 30A MPPT is designed for users who want premium performance in a smaller setup. Unlike standard controllers that require many panels in parallel, this unit supports high-voltage strings (up to 450Vdc), significantly reducing your wiring costs and complexity. It features RS485 BMS communication, allowing it to “talk” directly to your Lithium (LiFePO4) batteries to optimize charging cycles based on real-time cell data.

With its multi-stage charging algorithm and built-in circuit breakers for both PV and battery, it offers a level of safety and sophistication usually only found in large hybrid inverters. The intuitive LCD+LED display provides a clear view of your solar harvest and battery health at a glance.

• Best for: 12V or 24V residential systems using 1–3 high-wattage solar panels.

• Compatibility: Lithium, Gel, AGM, and Flooded batteries.

• Key Edge: High-voltage PV input means you can use modern 450W–600W panels with ease.
