Product information

Description

QOLTEC 40A MPPT solar charge controller for 12V/24V systems with an integrated LCD display provides efficient battery charging by continuously tracking the maximum power point of connected photovoltaic panels. The controller automatically detects system voltage (12V or 24V) and applies the MPPT algorithm to extract higher charging current compared with traditional PWM regulators, improving energy harvest from solar arrays in small to medium off-grid installations, recreational vehicles, boats and backup setups.

Advantages

The MPPT algorithm increases charging efficiency by optimizing voltage and current from solar modules, which can result in faster battery recharge and reduced power losses. The unit supports both 12V and 24V battery systems and delivers up to 40A output, enabling compatibility with a variety of battery capacities. The built-in LCD display shows real-time status, system parameters and allows access to configurable charging profiles and protection settings. Integrated protections include overcurrent, overvoltage, reverse polarity and temperature compensation, helping to maintain battery health and system safety.

Suitable for

  • Small and medium off-grid solar installations
  • RVs and motorhomes
  • Marine systems and boats
  • Home backup and stand-by battery systems

Key specifications

  • Maximum charging current: 40 A
  • Supported battery nominal voltages: 12 V / 24 V (automatic detection)
  • MPPT tracking for improved power conversion efficiency
  • LCD display for system status, settings and real-time parameters
  • Built-in protections: overcurrent, overvoltage, reverse polarity and temperature compensation
  • Suitable for lead-acid and similar battery chemistries with configurable charging stages

How to use

Install the controller in a dry, ventilated location close to the battery bank and away from direct sunlight. Connect the battery first, observing correct polarity, then connect the solar panel array following the manufacturer’s wiring recommendations. The device will automatically detect system voltage and begin MPPT regulation; use the LCD interface to review charging status, adjust charging parameters if needed and set battery type or charging profiles. Verify wiring and protections before leaving the system unattended.

Usage recommendations

For best performance, size the solar array and battery capacity so the controller operates under its rated current limit, allow adequate ventilation around the unit, periodically check cable connections and configure the correct battery type and charging voltages via the LCD to prolong battery life and ensure safe operation.
