SQ-MPPT-4188Boost Integrated Light Sources
Boost Integrated Light Sources
Boost integrated light-source driver — 20A charging, up to 60W LED drive, 8-segment dimming with adaptive dawn boost, suits 80W PV panels.
Product Features
- Designed for single-cell LiFePO4 systems — cells in parallel, no battery protection board needed, high capacity utilization, lower PACK cost
- Industrial-grade MCU all-digital technology — no trim resistors, strong anti-interference, no aging or drift
- Charging conversion efficiency up to 95.37% and MPPT tracking efficiency ≥99.9% with significantly reduced temperature rise
- Smart charging management (MPPT + CV trickle) keeps the battery in shallow charge/discharge cycles, greatly extending service life
- Smart LED drive: automatic light control, 8-segment dimming with independent power per segment
- Adaptive dawn-boost function with freely configurable duration and power
- Complete protection: battery reverse-polarity, PV reverse-polarity, reverse discharge at night, under-voltage, LED output open-circuit
