Supports GEL and LiFePO4 battery types and is designed for off-grid PV systems, RVs, boats and residential solar setups.

## Long description

QOLTEC MPPT Solar Charge Controller 80A is a multi‑voltage regulator designed for off‑grid photovoltaic systems that require efficient battery charging and system monitoring. The controller supports 12V, 24V, 36V and 48V battery systems and integrates Maximum Power Point Tracking (MPPT) to optimize energy harvest from solar panels. Built‑in features include an LCD display for local status and settings, Bluetooth connectivity with a companion mobile APP for remote monitoring and parameter adjustment, and a temperature sensor to apply temperature‑compensated charging. The device supports GEL and LiFePO4 battery chemistries and is intended for residential solar arrays, RVs, boats and similar installations.
Advantages
The MPPT algorithm increases charging efficiency by continuously tracking the panels’ maximum power point, which can yield higher energy capture compared with PWM controllers. Bluetooth and APP connectivity enable remote monitoring of voltage, current, and charging state, as well as convenient adjustment of charging parameters. The integrated temperature sensor ensures safer and more accurate charging by compensating charge voltage based on battery temperature. The LCD provides immediate local feedback on operating status, and support for both GEL and LiFePO4 batteries adds installation flexibility.
Suitable for
Small to medium off‑grid residential PV systems
RVs and camper electrical systems
Marine and boat battery charging
Remote cabins or workshops with solar power
Key specifications
Rated charge current: 80 A
Supported system voltages: 12 V / 24 V / 36 V / 48 V (automatic or manual selection depending on installation)
Charging algorithm: MPPT (Maximum Power Point Tracking)
Battery types supported: GEL, LiFePO4
Display: integrated LCD for status and settings
Connectivity: Bluetooth with mobile APP for monitoring and configuration
Temperature compensation: built‑in temperature sensor for charge voltage adjustment
Intended use: off‑grid solar charge regulation for battery systems
How to use
Mount the controller in a dry, ventilated location near the battery bank and within the recommended wiring distances for safety. Connect the battery first, observing correct polarity, then connect the solar panel array to the controller input, and finally connect the load output if used. Use the LCD to view system voltage, charging current and mode; navigate menus to select the correct battery type (GEL or LiFePO4) and system voltage if manual selection is required. Pair the controller with the vendor APP via Bluetooth to access real‑time data, historical parameters and to change advanced settings. Ensure fuses or circuit breakers are installed according to wiring best practices before commissioning.
Usage recommendations
For optimal performance, size the solar array and wiring to keep voltage drop low and stay within the 80 A continuous current rating. Configure the controller for the correct battery chemistry and enable temperature compensation to extend battery life. Periodically check connections, clean panel surfaces and monitor the APP logs to detect irregular charging events early.
