Qoltec off-grid 53875, 1.5kW 1MPPT single-phase hybrid inverter

Hybrid Inverter – Energy Independence for Your Home

This single-phase Qoltec hybrid inverter is the heart of an off-grid system, designed to convert energy from photovoltaic panels into usable power. The device combines the functions of an inverter, solar charge controller, and battery charger, providing independence from the power grid. An ideal solution for both demanding installers and users looking for a stable and ecological power source.

Key Features and Applications

The Qoltec inverter allows for efficient use of solar energy, charging batteries during the day and powering electrical devices from the stored energy. In the event of a power outage, the system automatically switches to battery power, guaranteeing continuous operation. The built-in MPPT charge controller with a power of 80A maximizes energy harvesting from photovoltaic panels, even in variable sunlight conditions. A clear LCD display allows you to monitor system parameters and configure settings.

• Off-grid mode: The inverter is designed to operate in systems independent of the power grid.
• MPPT controller: Maximum Power Point Tracking (MPPT) technology ensures optimal use of solar energy.
• Multifunctional LCD display: Allows monitoring of system parameters and configuration of settings.
• Solar and battery charger: 2-in-1 function – charging batteries with solar energy and powering electrical devices.
• Pure sine wave: Provides stable and safe power for sensitive electronic devices.
• Protections: Built-in protections against overload, overheating and short circuit protect the device and installation.
• Expandability: Compatible with an additional Wi-Fi module (available separately), enabling remote system monitoring.

Construction and Operating Parameters

The inverter is characterized by a solid construction and high efficiency (95%). It has IP20 protection, which means protection against touching foreign objects with a diameter greater than 12.5 mm. Automatic restart after AC power is restored minimizes the risk of system downtime. The device has a built-in RS-232 communication port for advanced diagnostics and configuration. Cooling is provided by two fans minimizing the risk of overheating during intensive operation.

The rated power is 1500 VA / 1500 W, and the nominal input voltage is 230 VAC. The device operates at a frequency of 50/60 Hz (automatic detection) and works with 12 VDC batteries, offering a maximum battery charging current (PV) of 80 A. The MPPT operating voltage range is between 100 – 450 VDC, and the degree of protection is IP20.

The manufacturer's warranty is 24 months, which confirms the high quality of the product and Qoltec's commitment to customer satisfaction. Remember the necessity of installation by a qualified installer with appropriate permissions to maintain the warranty validity.
