Power You Can Rely On
The central component of the system is a 5,000W hybrid inverter that provides stable power both in normal operation and during grid interruptions. This is enough power to support the operation of major household appliances, medical equipment, or smart home system elements. In case of peak load, the system provides up to 10,000 VA of instantaneous power, withstanding the start-up fluctuations of energy-intensive devices such as pumps, air conditioners, washing machines, etc.
Pure Energy Without Failure
The inverter guarantees a pure sine wave with < 3% distortion, ensuring stable and safe operation of even the most sensitive electronics. Switching from grid to backup power takes less than 10 ms.
Modular Battery System: Flexibility and Scalability
The VEZHA is equipped with two battery modules (each 5.12 kWh), which together provide a capacity of 10.24 kWh. These lithium-iron-phosphate (LiFePO₄) cells provide high efficiency, have enhanced thermal stability and can withstand up to 6,000 deep discharge cycles (80 % DOD). Each module is equipped with an intelligent BMS system that monitors temperature, voltage, current, and protects against short circuits, overloads, and overheating. The system can be scaled up by adding two more modules if required, for a total capacity of 20.48 kWh.
Revolutionary Wireless Architecture
A distinctive feature of the PowerWall VEZHA is the absence of traditional connection cables between the inverter and the battery module. Instead, it uses a unique power interface that transfers energy and data within the system without any wires. This greatly simplifies installation, increases reliability and reduces transmission losses.
Intelligent Energy Exchange
The VEZHA does not just store energy, it manages the flow of energy between sources, consumers and the battery. Thanks to a modern topological scheme, the system automatically determines where it is more appropriate to take energy from – from PV panels, the grid or batteries – and where to send it.
Photovoltaic Power Under MPPT Control
The MPPT Integrated PV charger (5.5 kW) is one of the most efficient controllers in its class. It continuously monitors the maximum power point of the solar array, adjusting the parameters according to the intensity of solar radiation and the temperature of the panels. The system supports an input voltage of 120 to 500 V and an MPPT range of 120 to 450 V, and a maximum current of up to 100 A.
Compactness Without Compromise
The PowerWall VEZHA has a very compact body with a depth of only 140 mm. The system can be easily integrated into the interior of a city apartment, a technical room in a private house or a server room in an office. The inverter weighs 25 kg, each battery pack weighs 45 kg, and the dimensions are 500 × 400 × 140 mm (inverter) and 500 × 500 × 140 mm (battery). Vertical installation is recommended.
Operation According to Tariff Zones
The VEZHA’s time-based charging and discharging function enables it to effectively adapt to multi-zone tariff plans. For example, the batteries are charged at night, when electricity is cheapest, and supplied during the day. This avoids expensive daytime tariffs. In combination with solar panels, this guarantees significant savings every month.
Unlimited Expansion: Parallel and Three-Phase Connection
One of the key advantages of the system is its scalability without loss of efficiency. Up to six VEZHAs can be combined on a single phase, delivering up to 30 kW of power and 120 kWh of energy. It is also possible to create a three-phase 380 V system, which is the optimal solution for private estates, office complexes or small industries. The three-phase connection allows for even load distribution and full interaction with equipment.
Everything Under Control: The 2E Smart Energy Mobile
The 2E Smart Energy mobile app, compatible with iOS and Android, offers extensive real-time monitoring capabilities. It allows you to control the amount of energy generated by the panels, determine how much the system consumes, how the batteries are recovering and which operating modes are activated. The software provides flexible analytics tools, an event log, and easy mode settings.
Certified Safety and Stability
The PowerWall VEZHA is designed to meet the highest quality and safety standards. The system is CE (EN62109-1) and EMC (EN61000) certified, IP20 rated, operates in a temperature range of -15 to +55 °C and is resistant to humidity up to 95%. Air cooling ensures stable operation and the noise level does not exceed 60 dB, which allows the VEZHA system to be used in residential areas without discomfort.
