High-Efficiency Charging,automatically detects 12V, 24V, 36V, and 48V solar battery voltages,Multiple Electronic Protections,Up to 12 Units in Parallel
1. Features
1) Integrated Charging Presets
Integrated charging modes include adaptive charging logic, suitable for most battery types such as flooded lead-acid batteries, gel-sealed lead-acid batteries, and lithium batteries. Specific charging parameters for each battery type can be found in Section 3.5.
2) Versatile Application
Compatible with 12V/24V/36V/48V system voltages.
3) Multi-Stage Charging Algorithm
The multi-stage charging algorithm is designed to optimize each charging cycle. After the batteries are fully charged, it maintains battery capacity by applying preset charging parameters in specific charging stages.
4) Maximum Power Point Tracking (MPPT) Technology
MPPT technology tracks the maximum power point voltage (Vmp) of the array as it varies with weather conditions, ensuring the collection of maximum power from the array throughout the day.
5) High-Efficiency Charging
Innovative MPPT technology with a tracking efficiency of up to 99.9% and a peak conversion efficiency of up to 97%, reducing power consumption, minimizing heat generation, and lowering operating temperatures.
6) Supports Up to 12 Units in Parallel
The parallel operation function allows for easy expansion of the solar panel configuration and energy storage capacity limits, thus increasing the scale of energy storage. For detailed parallel operation guidelines, refer to Section 7.
7) Adaptive Boost Charging
During the initial charging phase, adaptive boost charging monitors battery response and automatically determines the duration of the boost stage for each independent charging cycle, ensuring that the battery is fully charged at any discharge level or capacity while avoiding overcharging during the boost charging stage (extends battery life).
8) Durable and Secure
a. Photovoltaic input overcurrent
b. Photovoltaic array short circuit
c. Reversed photovoltaic polarity
d. Overvoltage protection for batteries
e. Overdischarge protection for batteries
f. Over-temperature protection
9) External Temperature Probe Configuration
Enhance precision in battery temperature monitoring by configuring an external temperature probe. This ensures accurate temperature compensation for optimal system performance.
10) Forced Air Cooling
Built-in cooling fan for forced heat dissipation, improving overall device operational efficiency.
11) Lithium Battery Activation
Compatible with lithium batteries. When the battery type parameter is set to lithium batteries, the charging cycle will be adjusted to accommodate the needs of lithium battery charging. Additionally, when connected lithium batteries are in a protected state, the controller will activate the lithium batteries with the energy from the solar panels, with current not exceeding the lithium battery protection voltage and current range.
Warning: Do not charge lithium batteries when the temperature is below 10 ℃.
