Qoltec Hybrid Solar Inverter Off-Grid 4kVA | 4kW | 120A | MPPT | LCD | Wi-Fi | BMS | Sinus

The performance of a photovoltaic system depends on the selection of the right inverter, or solar inverter. The inverter performs a key function in this system, changing the DC current generated by the photovoltaic panels into AC current used by household appliances. The off-grid hybrid inverter combines the photovoltaic system, the energy storage and the power grid. It uses excess solar energy to power consumers and charge the battery. When energy production is greater than current demand, the excess current can be transferred to charge LiFePO4, AGM, GEL batteries, allowing energy to be stored for later use, such as at night or on cloudy days. The hybrid inverter can automatically switch to off-grid mode, supplying energy from the batteries.

Increase in electricity production with a significant decrease in operating costs

The battery charging inverter uses a state-of-the-art 120A MPPT charge controller to maximize the power drawn from the photovoltaic panels, using advanced maximum power point tracking technology. Having this feature significantly affects the efficiency of the photovoltaic installation-they can maintain high power even in low sunlight conditions. In addition, the controller controls the battery operation and charging process and protects the battery from damage.

Continuous monitoring of battery performance

The built-in BMS battery management system is crucial for the long-term life of the battery in an off-grid system. The BMS monitors and manages battery parameters, ensuring optimal charging, discharging and protecting against overcharging or over-discharge. This allows users to enjoy a reliable source of energy for many years.

Continuous monitoring of battery performance

The product is equipped with a multifunctional, easy-to-use LCD display with control panel. Facilitates monitoring of the entire photovoltaic installation . Allows you to configure the input voltage range for home appliances and personal computers or change the priority settings of the AC/Solar charger. In addition, the display records data and informs about failures, reacting accordingly if any of the parameters exceed the norm. If a fault occurs, the inverter shuts down.

Remote management using a dedicated mobile app

With the SmartESS mobile app for iOS and Android devices, users can monitor and control the unit via their smartphones. This makes it possible to quickly detect possible faults or performance reductions in the installation.

RGB lights

The solar inverter housing with RGB diodes is an attractive design element for modern spaces combined with functionality. The use of RGB LEDs allows the colours of the housing to change dynamically. The RGB LED backlighting not only adds to the aesthetics, but also plays a practical role in informing users of faults.
