SRNE HP2440N 40 A Smart Solar Charge Controller
Overview
Robust 40 A PWM controller for 12 V / 24 V off-grid PV systems
Advanced 3-stage charging algorithm (bulk, boost, float) with equalization for lead-acid batteries and dedicated programs for sealed, GEL and lithium chemistries
Built-in temperature compensation automatically adjusts charging setpoints (lead-acid only), extending battery life
Key Features
Auto Voltage Detection: instantly recognizes 12 V or 24 V systems—no manual switches needed
Multi-Battery Support: select flooded, sealed, GEL or lithium profiles via the LCD menu
3-Stage PWM Charging: efficient bulk, boost and float charging, plus periodic equalization
Five Load Modes: pure light control, light + timer (1–14 h), manual on/off, test/debug, always-on
User-Friendly Interface: dot-matrix backlit LCD with two-button navigation for quick setup and real-time system status
Optional Connectivity: RJ12 port with TTL-232 or Bluetooth (Modbus) for PC or mobile-app monitoring
