PWHESS03 is the new generation of home energy storage system developed by Powerwise. It is a house-hold energy storage system adopting the longevous and environmentally friendly lithium iron phosphate batteries as the energy storage carriers and taking solar power generation as the main power supply. It could store the electricity emitted by solar energy into the battery and realize self-emitting and self-using. The redundant electricity emitted by solar energy is sent back to the grid through grid connection. Apart from saving energy, it could gain economic benefits through selling electricity to grid.

System Characteristics:
On-grid and off-grid working model. The electricity emitted by PV is stored into
Battery for self-using and the redundant electricity is connected to the grid
Advanced battery management system. It ensures that the system will get off the
Grid quickly when the grid power failure and turns into the off-grid model to
Operate. Guarantee the electricity safety
Solar energy, as the main power generation energy, is converted to power grid
Supply when it is insufficient, in order to ensure that the load has no power failure
And could charge electricity to battery
The system owns MPPT charging function and could ensure the maximization of
Solar power generation
Advanced battery management system: Adopt active balance technology and
Ensure lithium battery cycle life and discharge capacity maximization
Modular design: Support parallel operation function, single machine 3KW and
Could support 4 sets to output 12KW power to the maximum

Communication mode: RS485

Main Applications:
Green residence
Community and small industrial sites
Communication base
Areas with poor grid stability or without electricity
Areas adopting TOU power price
