【Product Description】
This is an Infinisolar MPPT (Maximum Power Point Tracking) solar charge controller, which offers 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 the product list!)【Advanced MPPT Technology】
The solar controller adopts the latest optimised 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 utilisation rate is ≥99% and the maximum efficiency is ≥98%.【Unlock 30% More Solar Power】
Compared 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 higher power for battery charging. Up to 245V 6250W PV input, allowing you to connect more solar panels for the whole system.【Compatibility With Various Batteries 】
The inverter features wide battery compatibility, allowing connection 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 Batteries 】
Compared to other inverters, we have adopted a 3-step charging algorithm for lead-acid battery, a 4-step charging algorithm for Lithium battery, which unlocks 30% longer battery life with precision parameter tuning.【Battery Equalisation Charging】
Extend battery lifespan by solving the problem of the voltage difference between each battery cell. Our MPPT controller's active balancing technology precisely equalises individual cell voltages during charging, eliminating weak-cell overcharge risks and permanently maximising battery storage capacity.【Parallel Operation Supported】
The controller supports parallel operation to increase the 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 conditions 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 RS-485 interface and communication cable, wired PC monitoring of the controller can be realised. 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 temperatures, and slows down for low noise operation. It utilises an aluminium alloy shell for superior heat dissipation performance, better than plastic shells. Its dust-proof cover effectively shields against dust ingress, ensuring prolonged lifespan in a 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.
