PowMr Efficient 35A MPPT Solar Charge Controller with Multiple Electronic Protections and Efficient Three-Stage MPPT Charging
1. Features
1) Integrated Charging Presets
The integrated charging modes include adaptive charging logic, making them suitable for most battery types, such as flooded lead-acid, sealed gel, and lithium batteries. Specific charging parameters for each battery type can be found in section 3.7.
2) Flexible Application
Compatible with 12V/24V system voltages.
3) 25A/35A/45A Charging Controllers
Available in 25A, 35A, and 45A charging current options to meet the needs of various solar energy storage systems.
4) Multi-Stage Charging Algorithm
The multi-stage charging algorithm is designed to optimize each charging cycle, maintaining battery charge through preset charging parameters for specific stages once the battery is fully charged.
5) Maximum Power Point Tracking Technology
MPPT technology tracks the maximum power point voltage (Vmp) of the array, which varies with weather conditions, ensuring maximum power is collected from the array throughout the day.
6) Efficient Charging
Innovative MPPT technology with tracking efficiency up to 99.9% and peak conversion efficiency up to 97%, reducing power consumption, heat generation, and operating temperature.
7) Adaptive Boost Charging
During initial charging, adaptive boost charging monitors the battery's response and automatically determines the appropriate boost stage duration for each independent charging cycle. This ensures the battery is fully charged at any discharge level or capacity, avoiding overcharging during the boost stage, thereby extending battery life.
8) Durable and Safe
a. Overcurrent protection for PV input
b. PV array short circuit protection
c. PV reverse polarity protection
d. Battery overvoltage protection
e. Battery over-discharge protection
f. Over-temperature protection
9) Accurate Battery Temperature Monitoring
When the battery temperature exceeds 80℃, temperature compensation is automatically performed, reducing charging power to protect the battery.
10) Lithium Battery Activation
Compatible with lithium batteries, the charging cycle will adapt when the battery type parameter is set to lithium. If the connected lithium battery is in protection mode, the controller will activate the lithium battery using energy from the solar panels, with current not exceeding the lithium battery protection voltage and protection current range.
Warning: Do not charge lithium batteries when their temperature is below 0℃.
