Description - Be energy independent
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.
Why should you choose a hybrid inverter?
pure sine wave inverter, automatic restart during power restoration, easy-to-read 4.3-inch LCD multifunctional touchscreen display, 120A MPPT charge controller, ability to be powered by mains or generator, ability to change AC/Solar charger priority settings via LCD display, intelligent charger design for optimal battery performance, configurable input voltage range for home appliances and personal computers using the settings on the LCD display panel, configurable battery charging current according to devices and personal computers via settings on the LCD display panel, cold start function, built-in Wi-Fi for mobile monitoring (Android/iOS app available), reserved communication port for BMS (RS485, CAN-BUS, Rs232), housing with RGB LEDs. Maximize the possibilities with MPPT technology
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.
Battery Management System (BMS)
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.
Multifunctional touch-screen LCD display
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.
Manage and monitor easily
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.
Unique combination of functionality and aesthetics
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.
