About this item
POWLAND 120A MPPT Solar Charge Controller
The POWLAND 120A MPPT Solar Charge Controller is a high‑capacity solar charge regulator designed to optimize energy harvested from your solar array and protect your battery bank. Using MPPT (Maximum Power Point Tracking) technology, this controller maximizes power conversion efficiency and enhances system performance in residential, off‑grid, RV, and larger solar setups.
Key Features
☀️ 120 A Maximum Charging Capacity
This controller can deliver up to 120 amps of charging current, making it suitable for medium to large solar systems with substantial panel arrays.
🔌 Wide Voltage Compatibility (12 V to 96 V)
Automatically detects system voltage across a wide range — from 12 V up to 96 V — so it works with many solar configurations without manual switching.
📈 Up to 98 % MPPT Efficiency
Advanced MPPT tracking algorithms help extract more solar power from your panels — up to about 30 % more energy than traditional PWM controllers.
📊 Smart LCD Display
Integrated LCD shows real‑time system data such as:
- Solar array voltage & current
- Battery voltage & state
- Charging stage and mode
- System faults and warnings
This helps you monitor performance and troubleshoot quickly.
🔋 Multi‑Stage Intelligent Charging
Provides a 3‑stage charging profile (bulk, absorption, float) to safely and efficiently charge a variety of battery types, boosting battery life and performance.
🔐 Comprehensive Protection Features
Built‑in safeguards include:
- Reverse polarity protection
- Overload and over‑current protection
- Open‑circuit protection
- Temperature compensation/over‑temperature cut‑off
These features protect both controller and battery against common faults.
🔋 Battery Compatibility
Supports multiple battery chemistries including:
- Lead‑acid (AGM, Gel, Flooded)
- LiFePO4 lithium batteries
Ensuring flexibility across system designs.
How It Works
The controller continuously analyzes the PV array output and battery needs, adjusts the operating point to find the maximum power point, then matches the solar panel output to the battery voltage. This ensures maximum solar power extraction and efficient charging, especially under varied lighting conditions like early morning or shaded panels.
