## Summary description

MPPT solar charge controller QOLTEC 10A for 12V/24V systems with LCD display. Implements maximum power point tracking to optimise solar panel output and charge batteries efficiently up to 10 A. Compatible with 12 V and 24 V battery systems, features an LCD for status and settings, and provides protection functions for safer charging. Suitable for small off-grid and backup applications.

## Long description

MPPT Solar Charge Controller QOLTEC 10A for 12V/24V systems with LCD display is a compact regulator designed to optimise power harvesting from photovoltaic panels and manage battery charging for small off‑grid and backup installations. The controller supports both 12 V and 24 V battery systems and adapts its charging profile using maximum power point tracking (MPPT) to increase charging efficiency and reduce energy losses. An integrated LCD provides real‑time status, voltage and current readouts, and access to configurable charging parameters. Built‑in protections guard against overcharge, reverse polarity and short circuits to ensure safer operation.
Advantages
The MPPT algorithm improves energy conversion compared with simple PWM controllers, allowing higher battery charge current under variable sunlight conditions. The controller’s automatic system voltage detection simplifies setup for 12 V or 24 V battery banks, while the LCD display gives clear feedback on system voltage, charge current and mode settings. Protective functions reduce the risk of battery damage and provide a level of operational safety during installation and use. Its compact footprint and straightforward interface make it suitable for rapid deployment in small installations.
Suitable for
 Small off‑grid photovoltaic systems for cabins, sheds or boats
 Backup power setups for routers, CCTV or small appliances
 12 V or 24 V lead‑acid and compatible battery banks requiring regulated charging
 DIY solar projects where compact MPPT regulation is desired
Key specifications
 Maximum charging current: 10 A
 Supported battery voltages: 12 V / 24 V (automatic detection)
 MPPT tracking to optimise panel power output
 LCD display for status, voltage, current and configuration
 Protection features: overcharge protection, reverse polarity protection, short circuit protection
 Suitable operating environment: indoor or sheltered outdoor installation
How to use
Mount the controller on a stable surface in a dry, ventilated location. Connect the battery first, observing correct polarity, then connect the solar panel array to the PV input. The controller will automatically detect the system voltage (12 V or 24 V) and begin MPPT regulation. Use the LCD interface to view real‑time voltage and current and to adjust charging parameters if needed. Verify protective indicators on the display during initial commissioning and consult the product documentation for parameter ranges and fault codes.
Usage recommendations
For optimal performance, match the solar panel open‑circuit voltage and array configuration to the controller’s recommended input range and keep battery connections tight and corrosion‑free. Place the controller away from direct weather exposure and heat sources, and periodically inspect wiring and terminal tightness. When used with lead‑acid batteries, follow manufacturer guidance for charging voltages and temperature compensation if available.
