Is the BESS container weatherproof?

Yes, optional containers feature an IP65 rating with fire protection and ventilation systems.

What battery technology is used?

The system uses LiFePO4 lithium batteries with high energy density and smart BMS.

What are the available solar panel options?

N-type Monofacial or Bifacial panels ranging from 420W to 750W with black or silver frames are available.

Can this system work with my existing solar panels? What if I have a diesel generator?

Yes,this hybid inverter accepts PV input from any standard panels(350w-750w) and has a dedicated generator port.It can automatically switch between solar,battery,grid,and generator-giving you true energy independence.

Can I add more than two units later? How far can I scale?

Yes.You can start with 2 units and add one unit at a time-no need to reconfigure. Each new unit is auto-recognized by the EMS. Pay-as-you-grow scaling.
