Why Shengqi
Key specs can be checked in the datasheets; samples can be requested for verification.
Integrated Hardware & Software
System design, PCB layout, embedded software and production ramp-up are handled by our in-house team.
High-Efficiency MPPT
MPPT boost topology with synchronous rectification — early low-light start and stable peak tracking.
Coulomb Counter + AI
Built-in coulomb counter precisely tracks battery capacity, ensuring runtime on cloudy and rainy days.
Smart Connectivity
Selected models offer Bluetooth or IR; Bluetooth models support WeChat mini-program tuning and OTA, with radar / IoT interfaces available.
Outdoor Protection
Potted, open-frame and light-source series are IP65-rated; the potted range adds an aluminum housing and -40°C to 80°C operation.
Multiple Protections
Controllers feature overcharge/over-discharge, reverse polarity, PV short circuit, LED open/short circuit and over-temperature protection.
Core Specifications
Tracking efficiency measures peak capture; conversion efficiency measures how much energy reaches the battery.
