A versatile, high-performance charge controller built for any battery voltage. The SMK 40A MPPT automatically detects 12V, 24V, 36V, or 48V systems, delivering up to 99.5% efficiency with quiet, fanless heat dissipation for reliable daily operation.
The SMK 40A MPPT Solar Charge Controller is engineered to adapt to a wide range of solar systems — from small cabins and shops to medium-sized homes and office setups.
Its heavy-duty aluminum heatsink enables silent, fanless operation, making it perfect for indoor installations or protected outdoor environments where quiet performance matters.
With high-voltage PV input support up to 450VDC, it efficiently harvests solar energy even under low-light conditions, ensuring maximum output from your panels throughout the day.
The built-in PV/Battery breaker eliminates the need for external fuse boxes, simplifying installation. Meanwhile, the RS485 communication port ensures seamless integration with modern Smart Lithium batteries.
The controller automatically detects and supports:
No manual configuration required — it adapts to your battery bank instantly.
