1.1 Features
⚫ 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.
⚫ Versatile Application
Compatible with 12V/24V/36V/48V system voltages.
⚫ 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.
⚫ 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.
⚫ 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.
⚫ 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.
⚫ 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).
⚫ Durable and Secure
a. Photovoltaic input overcurrent
b. Photovoltaic array short circuit
