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.
Compatible with 12V/24V/36V/48V system voltages.
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.
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.
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.
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.
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).
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
Precisely monitor battery temperature. When the battery temperature exceeds 65°C, charging is stopped, and when the battery temperature drops below 55°C, charging is resumed to protect the battery.
Built-in cooling fan for forced heat dissipation, improving overall device operational efficiency.
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.
The controller device is capable of standalone operation for individual units and can also support
a maximum of 12 units in parallel operation. When operating in parallel, communication between
the parallel controllers is achieved through communication lines. The parallel controllers are
installed at the same horizontal height.
Each controller must be connected to a separate solar array. One solar array cannot be
simultaneously connected to more than one controller. The input power connected to each
controller should not exceed the rated input power of a single controller.
Parallel controllers are connected to the same battery bank.
