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 electricity production while significantly reducing 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. This feature significantly enhances the efficiency of the photovoltaic installation—maintaining high power even in low sunlight conditions. Additionally, the controller manages battery operation, regulates the charging process, and protects the battery from damage.

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 protection against overcharging or over-discharge. This allows users to enjoy a reliable source of energy for many years.

Multifunctional LCD display

Continuous monitoring of battery performance.

The product is equipped with a multifunctional, easy-to-use LCD display with a control panel. It facilitates monitoring of the entire photovoltaic installation, allows configuration of the input voltage range for home appliances and personal computers, and enables changing the priority settings of the AC/Solar charger. Additionally, the display records data, informs about failures, and reacts accordingly if any of the parameters exceed the norm. If a fault occurs, the inverter shuts down.
