Description

The SMK 40A MPPT is the “Swiss Army Knife” of charge controllers. Whether you are running a simple 12V cabin or a professional 48V home backup, this unit adapts automatically. It is built for the rugged Nigerian environment, featuring a heavy-duty heatsink for quiet operation and a built-in PV/Battery breaker that eliminates the need for external fuse boxes.

By utilizing high-voltage PV input (up to 450Vdc), it harvests more energy in low-light conditions compared to PWM controllers. The RS485 port ensures seamless integration with modern Smart Lithium batteries, while the multi-stage charging profile keeps older lead-acid or Gel batteries in peak condition by preventing overcharging cells.

• Best for: Medium-sized home systems (48V) or high-power 24V setups.

• Safety: Comprehensive protection against short-circuit, reverse polarity, and over-temperature.

• Monitoring: Dual LCD/LED display for real-time tracking of voltage and amperage.
