10A MPPT Solar Charge Controller LCD

Size: 133 × 70 × 50 mm. Designed for ease of integration — terminal labels (PV/BAT/LOAD/USB) are laser-etched and corrosion-resistant; screw terminals accept 10–16 AWG wire with torque specification marked for repeatable, low-resistance connections. Core MPPT engine achieves ≥99.5% tracking accuracy and up to 98% conversion efficiency, backed by component-level validation — including low-ESR capacitors, shielded inductors, and thermally anchored MOSFETs. MPPT algorithm prioritises stability over speed during low-SNR conditions (e.g., fog, heavy overcast), avoiding oscillation that wastes energy. LCD provides persistent, non-volatile display of five operational metrics: charge current (A), discharge current (A), total generation (kWh), total discharge (kWh), and internal temperature (°C) — all updated every 2 seconds. Load control supports both light-dependent and time-based activation, with user-settable hysteresis to prevent flickering near threshold. USB outputs feature current-sharing logic and individual over-temperature shutdown — if one port overheats, only that port disables while the other remains functional. Protection logic uses redundant sensing (voltage, current, temperature) and hardware watchdogs to guarantee fail-safe response — e.g., reverse polarity detection cuts PV input within 10ms, before any component stress occurs.
