Hybrid single-phase inverter Qoltec off-grid 53874, 4kW 1MPPT, WIFI

Hybrid inverter – energy independence for your home

This off-grid hybrid inverter from Qoltec is the heart of a power system based on solar energy. It is designed to power electrical devices with energy from photovoltaic panels, offering independence from the power grid. The device is perfect for both home installations and places where access to the grid is difficult or impossible. Thanks to the built-in MPPT charge controller and compatibility with various types of batteries, it ensures efficient collection and use of solar energy.

Functionality and versatility

The inverter converts direct current (DC) from photovoltaic panels into alternating current (AC) used by household appliances. It has a built-in MPPT charge controller with a power of 120A, which maximizes energy harvesting from the panels, even in variable sunlight conditions. It is compatible with LiFePO4, AGM, GEL and DEEP Cycle batteries, giving you a lot of freedom in choosing an energy storage system. The built-in BMS (Battery Management System) monitors the condition of the batteries, ensuring their optimal operation and long life. In addition, remote monitoring via Wi-Fi (available application for Android/iOS) allows you to continuously monitor the system's operation and quickly respond to any problems.

User comfort and safety

A clear, touch LCD screen makes it easy to configure and monitor the inverter's parameters. The device has protections against short circuit, overheating, overload and battery overcharge, which guarantees safe operation. Automatic restart after AC power is restored minimizes downtime in energy supply. The housing with RGB LEDs informs about the device's operating status. The IP20 protection class provides protection against touching with fingers and against solid objects larger than 12.5 mm – ideal for mounting in dry and well-ventilated technical rooms.
