Residential Single-phase Distributed Energy Storage System Panda-S Series PAN 3000B-S1~PAN 6000B-S1

Residential Single-phase Distributed Energy Storage System Panda-S Series PAN 3000B-S1~PAN 6000B-S1

Modular design for the whole system enables stacked installation for flexible energy capacity expansion.

This product supports GPRS/WiFi/RS485/USB interfaces, LCD display, app and web page remote monitoring.

The style of white appliance makes it a good fit among modern home appliances.

A design featuring light and slim requires simple installation
and little space only. This product supports zero power off with seamless switching between off-grid and on-grid.

Smart air cooling for thermal dissipation at low temperature rise with multiple
protection against over-voltage, under-voltage, over-current, over-temperature and other functions.

Ultra wide PV voltage range of 120-550 V and ultra large current of 13.5 A support panels for large capacity.
