Features and benefits

Why I love EASUN POWER 80A/100A MPPT

Advanced MPPT Technology: The core of this controller is its advanced Maximum Power Point Tracking (MPPT) technology, boasting an efficiency greater than 99% and a peak conversion efficiency exceeding 98%. This ensures that your solar panels are always operating at their optimal power point, extracting the maximum possible energy from the sun, which translates directly into faster battery charging and greater overall system output, especially beneficial during fluctuating light conditions.
Versatile Battery Voltage Compatibility: With automatic detection for 12V, 24V, and 48V battery systems, and a configurable setting for 36V, this controller offers exceptional flexibility. This broad compatibility means it can be seamlessly integrated into a wide range of existing or new solar setups, reducing the need for specific voltage matching components and simplifying system design for various applications.
Comprehensive Multi-Stage Charging: The controller employs a sophisticated 3-stage charging mode, which includes an equalization charging function, specifically designed to optimize battery performance and extend their lifespan. This intelligent charging process prevents overcharging and ensures that batteries are charged efficiently and safely, accommodating various battery types such as Lead-acid (AGM/GEL/Flooded) and Lithium batteries.
Robust Protection Features: A full suite of protection functions is integrated to safeguard both the battery bank and the solar array. These include battery overcharge protection, high and low temperature protection, reverse polarity protection, overcurrent protection, controller over-temperature protection, PV array short circuit protection, and PV reverse polarity protection. These critical safeguards ensure the longevity and reliability of your entire solar power system, minimizing risks of damage from electrical faults or environmental extremes.
High-Speed DSP Processor and Communication: Utilizing DSP processor technology, the controller guarantees high-speed operation and superior performance in managing complex power algorithms. Furthermore, it supports RS485 communication with Modbus protocol, enabling seamless integration into larger monitoring and control systems. This feature is invaluable for advanced users and system integrators who require remote monitoring, data logging, and precise control over their solar installations.

Authentic Feedback Analysis:
⭐ 5.0/5 | AliExpress Shopper (CL): «Arrived in a few days, already installed and working correctly. It looks well-made and of good quality.»
⭐ 4.0/5 | n***n (US): «The box stated ‘lithium battery’ but my inverter detects it as ‘gel battery powered’. I feel somewhat misled, though the unit itself works well. I ended up with a cheaper battery type than expected.»
⭐ 4.0/5 | V***y (UA): «The controller performs as expected, providing stable charging. However, the documentation could be more comprehensive regarding battery type configuration.»
