Reliability and Power in One Solution
The 2E PowerWall VEZHA backup power system is the answer to today’s energy instability challenges. Equipped with a powerful 5,000W hybrid inverter, it not only provides stable power during power outages, but also supports the function of selling electricity back to the grid. At its heart is a 5.12 kWh battery module that can store energy for later use at any time. And all of this is housed in a fairly compact body measuring 500 × 400 × 140 cm.
Game-Changing Innovations
The VEZHA operates with a wireless connection between the inverter and battery modules. There are no thick cables – data and energy are transmitted through a unique power interface that ensures high efficiency and reliability of the system.
The key advantage is the use of lithium iron phosphate batteries (LiFePO4). They guarantee high performance, stable operation in a wide temperature range and have a service life of 6,000 cycles at a discharge depth of 80 %. The integrated intelligent BMS control system ensures safety and control of each cell, and the modular design allows for scalable capacities of up to 20 kWh.
Maximum Solar Power with MPPT
The VEZHA PV module is the epitome of efficiency. Thanks to MPPT (maximum power point monitoring) technology, the system adapts in real time to changing lighting conditions, getting the most out of the solar panels. The MPPT module supports up to 5.5 kW of power, operating in a wide voltage range from 120 to 450 V.
An advanced control algorithm enables the VEZHA system to efficiently combine energy flows from the sun, grid, batteries and loads, providing fully digital current and voltage control. All consumers receive a pure sine wave, which is necessary for the most demanding household and professional appliances.
Intelligence That Optimises Every Kilowatt
The system supports multi-zone tariff plans. This means that the user can set up charging and discharging schedules according to daily tariffs, making the most of cheap nighttime electricity or solar power during the day. This approach can significantly reduce energy costs.
Great Scalability
The VEZHA PowerWall system has no scalability limitations. By connecting up to six units, you can achieve up to 30 kW of power and 120 kWh of energy in a single-phase network. Or create a three-phase 380 V system by combining three inverters. This opens up the possibility of using the PowerWall VEZHA not only at home, but also at enterprises, offices or commercial establishments.
Always Under Control – 2E Smart Energy
The 2E Smart Energy app, available for Android and iOS, allows you to monitor the system in real time. From your smartphone, you can view the current load, battery status, energy sources, consumption history, and more. This transparency makes managing the VEZHA system not only easy, but also surprisingly efficient.
