MPPT Solar Charging Controller 12V/24V 40A IP32 Waterproof Fast Response for RVs Home Yachts

Feature: 1. MPPT Algorithm: The maximum power tracking algorithm can significantly improve the energy efficiency of the system, and the charging efficiency is 30% higher than that of the PWM method. 2. Features: Locate better operating point of the I‑V curve at a high speed, faster response speed and higher tracking efficiency, MPPT tracking efficiency is as high as 99.9%, and circuit energy conversion efficiency is as high as 98%. 3. Comprehensive Electronic Protection Functions: Features battery reverse connection protection, PV reverse connection protection, PV short circuit protection, charging overcurrent protection. 4. Support for Modbus Protocol: In line with the communication needs of various environments and occasions. Solar energy systems such as households, power stations, off‑grid, base stations, RVs, yachts, ships, etc. can be used. 5. Device View: You can view the operating data and status of the device with an external LCD screen (not included) or Bluetooth module (not included), and support to modify the controller parameters. 6. Built‑in Temperature Detection: Through derating charging, it can still keep stable operation under extreme temperature environment without fan. Support a variety of batteries, users can customize charging parameters. 7. Current‑Limiting Charging: When the solar panel power is too large and the charging current is higher than the rated value, the controller automatically reduces the charging power to make the solar panel work at the rated charging current.
