Qoltec Modular Hybrid Solar Inverter Off-Grid 8kW | 120A | 48V | MPPT | Sinus

The efficiency of a solar PV 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 solar PV panels into AC current used by household appliances. The off-grid hybrid inverter combines the solar PV system, energy storage and the power grid. During the day, it charges the energy storage from the photovoltaic panels. The energy storage unit powers household appliances from the stored energy during the day, and when the batteries are discharged, it draws energy from the grid. The inverter works in off-grid mode, using excess solar energy to power consumers and charge the battery. In the event of an emergency, current is drawn from the solar PV system to the energy storage and can safely and uninterruptedly ensure the continuous operation of our appliances.

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.

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.

Possible increase in system capacity to 48kW by connecting 6 units in parallel.

The product comes with a 24-month warranty from the date of purchase.
