OOYCYOO 100A MPPT Solar Charge Controller 12V/24V — LCD Display, Dual USB, High-Efficiency MPPT Tracking

Designed for off-grid arrays, RVs, boats and small commercial installations, this OOYCYOO MPPT regulator converts varying solar panel input into the optimal charging current for 12V or 24V battery banks. With a 100A maximum charge current and peak panel power support up to 2600W (24V), the controller balances fast charging with battery safety through programmable thresholds, temperature compensation and several automatic protections.

How does this controller increase solar panel efficiency?

The MPPT (Maximum Power Point Tracking) algorithm continually finds the most productive voltage/current point on your solar array so the panels operate nearer their peak output. Compared with conventional PWM controllers, MPPT typically delivers 20–40% more usable energy under typical conditions.

• High tracking efficiency up to 99% with advanced MPPT algorithm
• Accepts panels with VOC up to 48V (suitable for 12V or 24V systems)
• Supports peak 1300W (12V) / 2600W (24V) solar input
• Automatic 12V/24V system detection for simple setup

What protections keep my battery and system safe?

This controller includes a suite of automatic safety features that prevent damage and prolong battery life. It monitors voltage and current in real time and responds to faults with automatic shutdown or recovery as needed.

• Overcurrent and short-circuit protection with auto-recovery
• Reverse polarity protection for battery and panel connections
• Battery low-voltage cutoff and automatic reconnection at recovery voltage
• Temperature compensation to adjust charging for battery longevity

How do I monitor and control the unit day-to-day?

An integrated LCD presents charge/discharge currents, voltages and operating modes on one screen so you can check performance at a glance. Manual controls let you open/close the load, reset parameters, or restore factory defaults without complex tools.

• Clear LCD with real-time voltage, current and status indicators
• Dedicated keys for load on/off and factory reset
• Parameter reset and time-controlled operation options
• LED indicators to quickly verify connections and lightning protection
