Qoltec Modular Hybrid Solar Inverter Off-Grid 6200W 120A 48V MPPT 12 units BMS AGM GEL LiFePO4 Sinus Wi-Fi option Power factor 1.0

Be energy independent

How does the hybrid inverter work in off-grid mode ?
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, converting the DC current generated by the photovoltaic panels into AC current used by household appliances. The off-grid hybrid inverter connects the photovoltaic system, energy storage and the 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 or energy storage 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.

Maximize the possibilities with MPPT technology

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.

Multifunctional touch-screen LCD display
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.

Advantages of a modular inverter
Connect up to 12 units in parallel
To increase the power and efficiency of the system, up to 12 inverter units can be connected in parallel.
Advantages of combining 12 units:

– Ability to gradually increase the power of the system depending on demand.

- Greater reliability in case of failure one unit the rest of the system continues to work.

- Better energy management – Intelligent load sharing between units ensures energy efficiency.

- Loss reduction – The ability to operate within an optimal range of voltages and intensities improves system performance.

- Flexibility – The ability to adjust the configuration to different operating conditions (e.g., PV priority mode, battery priority mode, hybrid mode).

Battery Management System (BMS)

Manages battery parameters for optimal charging and discharging
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.
