SQ-MPPT-5013-20WOpen-Frame MPPT Controllers

Open-Frame MPPT Controllers

MPPT boost IR controller — 8A charging, up to 30W LED drive, suits 25W PV panels for low-power street lights.

Designed for single-cell battery systems — cells in parallel, simple PACK, no external battery protection board, lower cell capacity / internal-resistance matching requirements, high capacity utilization and lower Li-battery production cost
MPPT tracking efficiency ≥99.9%, system efficiency up to 95%, charging conversion up to 92% — high charging and LED drive efficiency keeps temperature rise low
Smart charging management: MPPT charging with CV trickle charge, and energy management that keeps the battery in shallow charge/discharge for a much longer service life
Smart LED drive management: automatic light control (on at dusk, off at dawn), 8-segment timer dimming with independent power per segment
Flexible parameter setting — IR communication, discharge curves freely programmable via engineering remote
Industrial-grade MCU all-digital technology, no trim resistors, strong anti-interference with no aging or drift; IP65 rated
Complete protection: no night-time reverse current into the PV panel, battery under-voltage and recovery protection, charging protection, LED output open/short-circuit protection
