Applications

Residential photovoltaic self-consumption
Backup during grid outages
On-grid, off-grid, and hybrid homes
Condominiums and small businesses
Balcony solar system under waitlist

Highlights

LFP chemistry, modular expansion, and compatibility with major inverter brands.
Color display, intelligent cloud control, OTA updates, and O&M diagnostics.
On-grid/off-grid switching below 20 ms in the integrated systems shown in the material.
The balcony line offers Wi-Fi/BLE, IP65, and a 10-year warranty, but is not yet available for immediate sale.

Residential flow between solar panels, inverter, battery, loads, and grid

Residential hybrid flow

Photovoltaic generation feeds loads, stores surplus in the battery, and maintains grid connection through the hybrid inverter.

On-grid flow prioritizing loads, battery, and grid export

Single-phase on-grid operation

The operational priority is to serve loads, recharge storage, and export the surplus to the grid.
