Core Key Features
✅ 30A PWM Charging & 12V/24V Auto Voltage Recognition30A rated charging current for 300W-600W solar panel arrays; automatic 12V/24V voltage detection removes manual adjustment, compatible with all mainstream 12V/24V batteries (LiFePO4, lead-acid, gel, AGM)—universal fit for residential, mobile and outdoor solar systems.
✅ Backlit LCD Real-Time System MonitoringClear backlit LCD screen displays critical data at a glance: solar panel voltage/current, battery voltage/SOC (state of charge), charging current/mode, load status and fault codes—optimize charging performance with no professional technical knowledge required.
✅ 3-Stage Intelligent PWM Charging ModeAdopts Bulk → Absorption → Float three-stage charging, perfectly matching battery charging characteristics to maximize energy harvest, avoid overcharging damage and significantly extend battery cycle life.
✅ Comprehensive 24/7 Multi-Protection SafeguardsFull-system protection including overcharge, over-discharge, reverse polarity (solar/battery), short circuit, over-temperature and reverse current protection (nighttime anti-discharge)—prevents wiring errors and component damage for total peace of mind.
✅ Integrated Charging + Load ManagementBuilt-in light and time control functions for optional solar load connection (e.g., outdoor lights, small appliances, water pumps); ultra-low standby power consumption minimizes energy loss during system idle time.
✅ Rugged, Weather-Resistant & Space-Saving DesignFlame-retardant ABS casing with dust-proof and splash-proof construction for indoor/outdoor installation; clearly marked wiring terminals and easy wall-mounting for hassle-free DIY setup, ideal for compact spaces.
✅ User-Friendly One-Button OperationSimple button control to switch display data, customize charging parameters and set load working modes; all settings are saved automatically with no repeated calibration—suitable for solar beginners and enthusiasts alike.
