PWM Solar Charge Controller, 12/24V Automatic Detection

【Automatic Detection】The solar charge controller automatically detects 12V or 24V battery voltages, simplifying the installation of your off-grid solar system without manual adjustment.
【Intelligent PWM Logic】Tandem pulse-width modulation regulation adjusts the current during the absorption and float phases, reducing sulfation and extending the life of deep-cycle batteries.
【CPU Thermal Control】The high-speed processor monitors the temperature in real time and dynamically adjusts charging parameters, preventing overheating in engine compartments or storage areas.
【Fanless Sealed Design】Passive heat dissipation via a solid aluminum heatsink eliminates dust ingress and fan noise, ideal for enclosed spaces in RVs, boats, or isolated cabins.
【Precise A/D Sampling】High-precision analog-to-digital conversion ensures stable voltage readings, keeping batteries 12V/24V deep discharge within their safe operating range continuously.
