Hybrid Power
The heart of the system is a powerful hybrid inverter with a rated power of 5,000 W and a peak load of up to 10,000 VA. It is designed to provide full power to the devices under any conditions. The inverter does not just switch to standby mode in the event of a power outage – it does so in a fraction of a second (< 10 ms). The device converts the direct current from batteries or solar panels into a pure sine wave of alternating current with a frequency of 50 Hz. This is important: this waveform is safe for sensitive household appliances, computers, medical devices, etc. Distortion does not exceed 3 %, which confirms the signal quality.
15.36 Wh of Accumulated Power
The PowerWall VEZHA is equipped with three modular batteries with a total capacity of 15.36 Wh. Each module is a self-contained battery based on lithium iron phosphate technology (LiFePO₄), which combines environmental friendliness, safety, and durability. The battery has a service life of up to 6,000 cycles at 80 % discharge depth. The system’s feature is its modularity: you can start with one battery (5.12 kWh) and expand the system to four modules, i.e. up to 20.48 kWh, if necessary. The intelligent BMS (Battery Management System) is responsible for monitoring the status, protection and interaction of the modules.
Wireless Architecture
2E engineers have taken a step forward by abandoning traditional cable connections between the inverter and batteries. The VEZHA uses a wireless power bus to transfer power and exchange data. This not only greatly simplifies installation, but also eliminates potential points of failure, making the system neat and aesthetically pleasing.
Managing Charging According to Tariffs
The VEZHA supports the tariff charging/discharging function. This allows you to set the system to automatically recharge during periods of lowest tariffs, such as at night, and discharge during the day when electricity is more expensive. Or, you can use daytime solar energy to avoid grid consumption entirely. This functionality significantly increases cost-efficiency, allowing you to «play» with tariffs and reduce your bills.
Photovoltaic Efficiency
The VEZHA has a highly efficient PV MPPT (Maximum Power Point Tracking) controller that handles up to 5,500 W of solar energy with a maximum current of 100 A. Its purpose is to determine the maximum efficiency point of the solar array in real time and dynamically maintain it. Thanks to a wide range of operating voltages (120-450 V), the system operates efficiently in all weather conditions.
Pure Sine Wave
The digital control architecture ensures stable operation of the inverter through a dual closed-loop current and voltage control system. Pulse Width Modulation (PWM) technology produces a stable, pure sine wave output – without jerks, pulses or oscillations. This allows even the most sensitive appliances to be connected safely.
Smart Scaling
The system is easy to scale as needed. For a household user who needs basic autonomy, the VEZHA can operate as a standalone unit. But if the needs increase, the system supports the parallel connection of up to six inverters. This is up to 30 kW of power and up to 120 kWh of total battery capacity. This is enough power even for a private house with electric heating, a restaurant or a workshop. Need a three-phase system? The VEZHA is suitable for this as well. Three units can be combined into one complete 380 V three-phase system with a voltage of 398 V between the lines and 230 V between the phases and neutral.
Everything Under Control: The 2E Smart Energy App
Managing your system is as easy as installing it. The 2E Smart Energy mobile app, available for iOS and Android, allows you to monitor your entire system in real time. In particular, you can control the charge level, generation power, consumption and status of all modules. It is a full-fledged control panel in your pocket, available anywhere – at home, in the country or when travelling.
Reliability in the Details
Every detail of the PowerWall VEZHA has been thought out to the smallest detail. The batteries operate in a wide temperature range (charging: 0-45 °C, discharging: -10-45 °C) and have IP20 moisture protection. Cooling is provided by air, with a noise level of up to 60 dB. The system is CE certified and complies with EN62109-1 safety requirements and EN61000 electromagnetic compatibility standards.
