Why MPPT Technology Matters
MPPT stands for Maximum Power Point Tracking, a charging method that maximizes energy harvested from solar panels by constantly adjusting charging parameters. Unlike PWM controllers, MPPT controllers can improve charging efficiency significantly—often 20–30% in real-world conditions.
The OAE 60A MPPT solar charge controller uses MPPT to rapidly scan the full I-V curve of the solar array, identify the true maximum power point, and adjust in real time. This makes it especially effective under fluctuating sunlight, shading conditions, or when you use high-voltage solar panels feeding lower-voltage battery systems.
Key Features of the OAE 60A MPPT Solar Charge Controller
The OAE controller includes a broad set of features aimed at users who need flexibility, efficiency, and reliability.
1. Auto 12V/24V/36V/48V Battery System Detection
Users do not need to manually configure system voltage. Once the controller is connected to the battery, it automatically identifies whether the bank is 12V, 24V, 36V, or 48V. This helps avoid setup errors and speeds up installation.
2. Supports Four Charging Options
The controller includes four charging profiles:
- Sealed
- Gel
- Flooded
- User-defined
These ensure compatibility with AGM, sealed, gel, flooded/wet batteries, and lithium battery packs.
3. Max 150V Solar Panel Input
The max 150V input solar controller capability allows users to run multiple solar panels in series, reducing wire losses and improving efficiency over long runs.
4. High MPPT Efficiency (Up to 97%)
The OAE MPPT controller includes an advanced tracking algorithm offering up to 97% transfer efficiency and rapid maximum power point tracking within seconds.
5. LCD Display with Real-Time Data

- System mode display
- Historical records
- English and Chinese menu language options
6. Multiple Load Control Modes
Load control options include:
- Manual mode
- Light control (dusk-to-dawn)
- Light control + timer
- Always on mode
These allow users to automate lighting, pumps, ventilation fans, and other DC loads.
7. RS485 Communication
For those who need remote management, the controller includes RS485 communication. With an optional adapter, users can add Wi-Fi monitoring and view real-time system information through an app.
8. Strong Protection System
Included protections:
- Overcharging
