30A Solar Power Controller PWM Battery Charging Controller 12V-48V Lithium Battery Solar Charge Controller with Bulk/Boost/Float Charge LCD Display 12V/24V/36V/48V Auto Detection Dual 5V USB Output Controller ( Item#: E23781-30 )

The controller uses numerical control technology design, LCD display, automatic operation. Its pulse-width modulation (PWM) type battery charging mode, as well as control technology, will greatly extend the battery life.
This controller is suitable for the solar energy system (independent system), control the charging and discharging process automatically. The battery charging and discharging process of the controller is optimized, which can prolong the battery life and improve the system performance. Its self-test function and electronic protection function can avoid controller damage due to installation errors and system failures.

Features:
Integrated Charge Presets: Integrated charge presets combined with adaptive charge logic are well suited for most common battery types, such as LiFeP04, Gel and flooded lead-acid.
Flexible Application: Automatic identification of 12V/24V/36V/48V system voltage.
Multi-stage Charge Algorithm: The multi-stage charge algorithm is specifically engineered to optimise each recharge cycle and charge maintenance over extended periods.
Adaptive Boost Charge: Adaptive boost charge monitors the battery's response during initial charging and intelligently determines the appropriate boost charge duration for each individual charge cycle. This ensures that the battery is fully recharged regardless of the discharge level or capacity and avoids excessive time at the elevated boost charging voltage (that can accelerate battery aging).
Protection Against Overheating: When the equipment temperature exceeds 85°C, the control automatically stops charging. Resume charging when the equipment temperature is 75 °C.
Safety Assurance: Output short circuit protection, discharging protection, protection against reverse polarity connection.
Silent Operation: Totally silent operation since there is no cooling fan or moving parts, cooling is via natural convection.
Lithium Battery Compatible: Compatible with Li-ion (LiFePO.) batteries; when the battery type parameter is set to Lithium battery the charge cycle settings are altered to suit.
Warning: Do not charge Li-ion batteries if the battery temperature is below 0°C.

Compatible with lithium-ion and lead-acid battery, support user-defined batteries.
Automatic identification of 12V/24V/36V/48V system voltage.
A variety of protection functions to ensure the normal operation of the device and extend the battery life.
Natural air cooling heat dissipation, to achieve totally silent operation.
The 2.4-inch LCD screen enables real-time monitoring and parameter configuration.
Small size, light weight, easy and quick installation.
Built-in 2 USB ports with output of 5V and 2A.
User friendly setup, fast and easy commissioning via front panel LCD.
