【Product Description】
This is an Infinisolar MPPT (Maximum Power Point Tracking) solar charge controller which offer an efficient, safe, multi-stage charging process that prolongs battery life and assures peak performance from a solar array. Capable of supporting up to 1560 watts on 12 volts, 3120 watts on 24 volts, 4680 watts on 36V and 6250 watts on 48V. This off-grid controller was designed for large-scale solar projects, both mobile and stationary. (Note: The solar panel, battery and inverter are not included in product list!)

【Advanced MPPT Technology】
The solar controller adopts the latest optimized MPPT technology, which can quickly track the maximum power point of the photovoltaic array in any environment and obtain the maximum energy of the solar panel in real time. The photovoltaic utilization rate is ≥99% and the maximum efficiency is ≥98%.

【Unlock 30% More Solar Power】
Comparing to other MPPT controllers which limit solar arrays to 4800W (48V 100A System ), our controller safely supports 6250W solar panel installations. This design harvests 30% more solar energy even in low-light conditions to ensure the higher power for battery charging.

【Compatibility With Various Battery】
The inverter features wide battery compatibility, allowing connect to 12V/24V/36V/48V Lead-acid (AGM, GEL, FLA, SLA...) batteries, Lithium (LiFePO4) batteries and user-defined batteries. The max battery charging current is 100A, setting range is from 10A to 100A.

【Smart Charging Algorithm For Different Battery】
Compared to other inverters, we have adopted 3-step charging algorithm for lead-acid battery, 4-step charging algorithm for Lithium battery, unlocks 30% longer battery life with precision parameter tuning.

【Battery Equalization Charging】
Extend battery lifespan by solving the problem of voltage difference between each battery cell. Our MPPT controller's active balancing technology precisely equalizes individual cell voltages during charging, eliminating weak-cell overcharge risks and permanently maximizing battery storage capacity.

【Parallel Operation Supported】
The controller supports parallel to increase solar system's total capacity and boost overall power output. This design perfectly accommodates large-scale solar installations while enhancing system reliability and stability. (Critical note: Parallel units are unlimited, provided your battery bank can handle the combined high-current charging input.)

【Accurate Temperature Compensation】
With the included temperature sensor, the MPPT charge controller can measure battery temperature, and make a compensation that can keep the charging performance as in normal condition and extend battery life. BTS ratio can be set from -60mV/℃/cell to 0mV/℃/cell as you need.

【LCD Display & LED Indicators】
LCD screen and multiple LED indicators for displaying system operation information, allowing you to set parameters like charging current, voltage, etc.

【Wired PC Monitoring】
Through the RS485 interface and communication cable, wired PC monitoring of controller can be realized. The communication cable is included in the package list.

【Smart Cooling & Dust-Proof Design】
The built-in smart fan dynamically adjusts its speed based on controller temperature, runs faster for maximum cooling under high temperature, slows down for low noise operation. It utilizes an aluminum alloy shell for superior heat dissipation performance, better than plastic shells. Its dust-proof cover effectively shields against dust ingress, ensuring prolonged lifespan in challenging environment.

【8-Level of Safety Protections】
Meant to safeguard your system, the self-diagnostic capability can assess and protect against reverse polarity, PV over-voltage, PV over-current, battery overcharging, short-circuiting, and reverse current etc.
