SQ-M360B-SDPotted Controllers
MPPT Boost Mains-Complementary Bluetooth
MPPT mains-complementary Bluetooth controller — 25A charging, 60W output, 80W mains direct-supply; switches to mains at low battery, suits 80W PV panels.
Product Features
- Industrial-grade MCU all-digital technology — no trim resistors, strong anti-interference, no aging or drift
- Designed for single-cell LiFePO4 battery systems — no battery protection board needed, cells in parallel, high capacity utilization, lower PACK cost
- Synchronous rectification topology: MPPT tracking efficiency ≥99%, charging conversion efficiency up to 95%, output conversion efficiency up to 92%
- Mains direct-supply mode — mains kicks in automatically when battery voltage drops below the configurable threshold (default 3V)
- 12V mains supplement input, mains power configurable via mini-program; built-in coulomb counter with AI algorithm ensures runtime on cloudy/rainy days
- IP65-rated design with aluminum housing, low temperature rise, reliable in harsh environments
- Bluetooth & IR communication, OTA upgrade, radar / IoT module interface; discharge curve configurable via WeChat mini-program or engineering remote (8 time segments + dawn boost)
- Complete protection: overcharge, over-discharge (current-limited), battery reverse-polarity, PV reverse-polarity, PV short-circuit, LED open/short-circuit, over-temperature
