Impressive Compactness
The PowerWall VEZHA is designed to meet the needs of urban apartments, private homes and offices. With a housing depth of only 140 mm, it can be easily integrated into any room without disturbing the harmony of the interior. It has an elegant, modern and technologically advanced look, making it a successful design solution.
A Wire-Free System
One of the significant advantages of the VEZHA is the absence of conventional cables between the inverter and the battery modules. Thanks to the unique power interface, both energy and data are transmitted wirelessly. This not only simplifies installation, but also ensures maximum system safety, durability and reliability.
Powerful Lithium Iron Phosphate Energy Storage
The energy-saving component of the VEZHA is based on lithium iron phosphate (LiFePO₄) batteries. This is a new generation of battery technology that provides high energy efficiency, safety and stability. The module has a capacity of 5.12 kWh. The system includes up to four such modules, for a total of 20.48 kWh of energy available for power supply.
The integrated BMS (Battery Management System) controls each module individually and the entire battery: it monitors voltage, current, temperature, and protects against overvoltage, overheating and overload.
The New Generation Inverter: The Heart of the VEZHA System
The VEZHA inverter does more than just convert direct current to alternating current – it works as a multifunctional energy brain. It has a power output of 5,000 W with a peak output of 10,000 VA. It produces a pure sine wave with less than 3 % distortion, switches instantly in the event of a power outage (< 10 ms) and fully adapts to the needs of household appliances, servers, power tools and even high-power equipment.
The built-in dual digital control algorithms allow for precise voltage and current control, regardless of load or external conditions. The inverter operates over a wide input voltage range of 90 to 280 VAC, making it suitable for use even in unstable power grids.
MPPT Photovoltaic Module
The VEZHA is equipped with a 5,500 W MPPT (Maximum Power Point Tracking) module. Its function is to determine and maintain the maximum power point of the solar array in real time. This means that even in cloudy weather or in the evening, the system will operate as efficiently as possible, getting every available watt from the PV panels.
Tariff Scenarios
The intelligent multi-zone tariff function enables the VEZHA to recharge when it is most beneficial – at night or during the day using solar panels. The user can set the time intervals for charging and discharging the batteries, optimising costs, reducing the load on the grid and maximising benefits.
Ready to Scale: Parallel and Three-Phase Connection
For larger installations, the VEZHA is designed to be expandable. You can combine up to 6 inverter systems per phase – that’s 30 kW of power and up to 120 kWh of stored energy. And there is also the possibility of connecting to a three-phase system: three VEZHAs form one 380-volt three-phase station capable of providing power for large enterprises or residential complexes.
Control in the Palm of Your Hand: The 2E Smart Energy App
With the 2E Smart Energy mobile app (available for iOS and Android), you can always have information on how much energy is stored, what the load power is, what the solar output is, and the status of each module. The interface is clear, informative, and most importantly, it operates in real time.
