YKYWTRWL 80A PWM Solar Charge Controller 12V/24V 1920W with USB, Multi-Circuit Protection

YKYWTRWL 80A PWM Solar Charge Controller is a high-capacity 12V/24V automatic-identification charge regulator with USB output and multi-circuit protection for systems up to 1920W.

This compact controller combines industrial-grade microprocessor management with MOSFET-driven PWM charging to maintain safe, efficient battery charging and load control. Designed for off-grid lighting, small solar arrays, and battery-based systems, it manages charge and discharge cycles, protects the battery and connected devices, and offers user-adjustable load modes. The ABS housing and aluminum heat-sink deliver durable operation across a wide temperature range while the included temperature sensor helps optimize charging performance.

How does the YKYWTRWL controller manage battery charging and protection?

The controller uses PWM charge control governed by an STM8 microprocessor to regulate charging and prevent overcharge, overcurrent, and reverse-connection damage. Temperature compensation and configurable thresholds keep battery health extended without complex setup.

• PWM charge mode with MOSFETs for low-loss switching
• Float, low-voltage disconnect and reconnection thresholds preset for 12V/24V systems
• Short-circuit, over-current and reverse-polarity protection
• Temperature sensor input for compensated charging behavior

What power and system sizes can this controller support?

This model supports automatic 12V/24V recognition and handles up to 960W on 12V systems or 1920W on 24V arrays, making it suitable for medium-to-large residential or remote lighting arrays. Check panel Voc against the 48V maximum before installation.

• Rated current: 80A continuous
• Max PV open-circuit voltage: 48V
• Max input power: 960W (12V) / 1920W (24V)
• Recommended cable cross-section: 25mm2 (3# AWG) for main runs

How easy is installation and daily operation?

The controller mounts with standard spacing and uses straightforward terminal connections for PV, battery and load. Onboard buttons let you select load operating modes and adjust charge/discharge parameters without specialized tools.

• Mounting holes: 98mm × 178mm, fits common enclosures
• Simple button operation for mode and parameter changes
• Low no-load consumption (<30mA) conserves battery when idle
• Includes a user manual and temperature sensor for setup

What design and durability features improve long-term reliability?

The controller combines a robust ABS plastic shell with a thick aluminum heat sink to dissipate heat effectively and resist physical wear. Electrical components and protective circuitry are chosen for steady performance across the specified operating temperature and humidity range.

• ABS housing for impact resistance and lighter weight
• Aluminum alloy heat sink with improved thermal conduction
• Operating range -10°C to 60°C; storage -30°C to 70°C
• Low loop voltage drop (<200mV) to maximize charging efficiency

Who this is for: Installers, DIY solar enthusiasts, and small-home or cabin owners who need a dependable mid-power charge controller with flexible load control and strong protection features. It’s especially useful where 12V/24V automatic switching, USB device charging, and a durable compact package are required. Review your panel Voc and cable sizing before purchase, and use the included user manual and temperature sensor during setup for best results.
