PowMr 45A MPPT Solar Charge Controller

The PowMr 45A MPPT Solar Charge Controller is a highly efficient, intelligent, and robust solution designed to maximize the performance of off-grid solar systems. Featuring advanced Maximum Power Point Tracking (MPPT) technology, this controller ensures that solar panels operate at their maximum efficiency, providing optimal energy to your battery bank under all weather conditions.

Supporting 12V and 24V battery systems, the PowMr 45A MPPT controller is suitable for a variety of applications including home solar setups, small commercial installations, solar backup systems, RVs, farms, workshops, and rural solar systems.

Advanced MPPT Technology

At the heart of the PowMr 45A controller is intelligent MPPT technology. Unlike traditional PWM controllers that waste excess voltage, MPPT controllers track the maximum power point of solar panels and convert extra voltage into charging current. This leads to faster charging, higher energy efficiency, and maximized utilization of available solar power.

The PowMr 45A offers up to 99% tracking efficiency and 98% peak conversion efficiency, making it a perfect choice for cloudy, rainy, or partially shaded conditions.

Automatic 12V / 24V Detection

The controller automatically detects the system voltage (12V or 24V) and adjusts charging parameters accordingly. This smart auto-detection simplifies installation and reduces the risk of incorrect setup, making it user-friendly even for beginners.

Multi-Stage Battery Charging

The PowMr 45A MPPT controller uses a three-stage charging algorithm to protect and prolong battery life:

• Bulk Stage: Delivers maximum current for rapid charging.
• Absorption Stage: Maintains a stable voltage to complete charging safely.
• Float Stage: Keeps the battery fully charged without overcharging.

This charging strategy ensures safe, efficient, and long-lasting battery performance.

Battery Compatibility

The PowMr 45A supports a wide range of battery types:

• Flooded lead-acid batteries
• AGM and Gel batteries
• Lithium-ion batteries
• LiFePO4 batteries

Users can also define custom battery profiles to match specific system requirements.

High Power and Reliability

With a rated charging current of 45A, this controller can handle medium to large solar panel arrays efficiently. It ensures stable charging and long-term system reliability, making it ideal for both residential and commercial applications.

Comprehensive Protection Features

The controller comes with multiple safety features to protect your system:

• Overcharge and over-discharge protection
• Short-circuit and overcurrent protection
• Reverse polarity protection
• Over-temperature protection

These features ensure the longevity of batteries and connected devices.
