PowerWall VEZHA is a unified solution for use in apartments, houses, and offices. Thanks to its ultra-compact form factor (the system is only 140 mm deep), the device doesn’t clutter up space while maintaining interior aesthetics. PowerWall 2E VEZHA is a cutting-edge backup power system featuring a powerful 5,000 W hybrid inverter.
Maximum efficiency – minimum hassle
PowerWall VEZHA employs a revolutionary wireless connection technology between the inverter and battery modules, eliminating the need for thick cables, as energy and data transfer within the system occurs through a unique power interface.
A completely new topological circuit in the power module enables energy exchange among photovoltaic, grid, battery, and load components. The system also supports photovoltaic and grid charging functions.
The photovoltaic charging module uses an advanced optimized MPPT monitoring technology that quickly identifies the maximum power point of the solar array in any environment, ensuring maximum real-time solar panel energy output. In addition, the MPPT features a wide voltage range and supports a maximum photovoltaic array power of 5,000 W.
The grid charging module uses an advanced control algorithm to implement fully digital dual closed-loop voltage and current regulation. The wide AC input voltage range and comprehensive input/output protection functions ensure stable and reliable battery charging and protection. The inverter module features a fully digital intelligent design, uses modern PWM technology, outputs a pure sine wave, and converts DC to AC power – ideal for household appliances, power tools, and other AC loads.
Three main inverter modes of the VEZHA system:
- SOL – photovoltaic priority. The “Solar First” mode switches to grid power when the solar array does not supply enough energy or when battery charge drops below a set level.
- UTI – grid priority. Operates from the grid, switching to the inverter only in case of grid power failure.
- SBU – battery priority. The load is powered primarily by the solar system and battery; the system switches to the grid only when the battery voltage or charge falls below the set level. The battery can continuously supply energy to the load even when grid power is available.
