Qoltec off-grid 3.5kW single-phase hybrid inverter, 1MPPT 53870

Hybrid Inverter – Energy Independence for Your Home

This Qoltec 3.5kW off-grid single-phase hybrid inverter is the heart of a solar-powered system. Designed for off-grid operation, it converts energy from photovoltaic panels into usable electricity in your home, providing independence from the power grid. The device is perfect for both new and modernized installations, offering flexibility and efficiency.

Universal Application and Compatibility

The inverter allows you to power electrical appliances directly from solar panels or stored energy in batteries. It is compatible with various battery types – LiFePO4, AGM, GEL and DEEP Cycle – giving you a wide range of choices. The built-in MPPT charge controller with a power of 100A and the AC charger 80A ensure optimal use of solar energy and efficient battery charging. This makes the system efficient even in variable sunlight conditions.

Intelligent Energy Management and Monitoring

A multifunctional LCD display allows you to continuously monitor system parameters such as voltage, current, power and battery charge level. The ability to connect a compatible Wi-Fi module (product code 53963) enables remote access to data and full control over the installation. The built-in BMS (Battery Management System) takes care of the safety and lifespan of the batteries, protecting them against overcharging, excessive discharging and overheating. The MPPT regulator increases power intake from photovoltaic panels even with weak sunlight, and the intelligent charger design optimizes the battery charging process.

Safety and Reliability

The inverter has short-circuit, overheating and overload protection, which guarantees safe system operation. Automatic restart after AC power is restored ensures continuous operation. Protection class IP20 means resistance to dust and ensures safe operation indoors. The device meets the required safety standards confirmed by the CE certificate. Installation should be carried out by a qualified installer with appropriate permissions to maintain the warranty validity.
