P-6 36kWh Stackable Home Energy Storage
Price on request
The P-6 stacks 36kWh of LiFePO4 energy — one control unit on top of four 9000Wh battery modules — behind a 5500W bidirectional inverter. With a 5000W MPPT solar controller and 2500W fast charging, it turns rooftop PV into round-the-clock whole-home power for European households.

P-6 — Stacked for Whole-Home Solar Independence
The P-6 is a stackable home energy storage system built around one control unit and four 9000Wh LiFePO4 battery modules — 36kWh of usable storage in a single 750 x 490 x 1035mm footprint. Its 5500W bidirectional inverter powers the essentials of a European home: fridge, freezer, lighting, heating circulation pumps and home office loads, day and night.
Paired with rooftop PV, the 5000W MPPT controller (60-130V input) stores the sun’s daytime surplus and releases it after dark — raising self-consumption and keeping the household running through grid outages. A 2500W fast charger restores the full stack from the grid in about 5.5 hours when solar is not available.
Each white module carries LiFePO4 chemistry at 51.2V / 9000Wh with the battery type printed on the front, and the whole stack rolls on a black base with four swivel casters for final positioning. The smart LCD on the control unit shows charge level, power flow and system status at a glance.

Frequently Asked Questions
What can the P-6 run during an outage?
With 5500W of output and 36kWh of storage it covers the essentials of a European household through the night — fridge, freezer, lighting, heating circulation pumps and home office loads.
How does it charge from solar?
Connect rooftop PV to the MPPT input (60-130V, up to 5000W — suggested PV size 5000W). The controller stores daytime surplus for evening and night use.
How long is a full charge?
The 2500W fast charger restores the 36kWh stack from the grid in about 5.5 hours; with sufficient solar, PV tops it up during the day.
Where should it be installed?
A dry indoor space — utility room, basement or garage. Operating range is 0-55°C while charging and -20~60°C while discharging. Installation by a qualified electrician is recommended.
Who is the P-6 designed for?
European homeowners with rooftop PV who want higher self-consumption, whole-home backup through outages, and a compact stacked system — plus small properties such as guesthouses and rural businesses.
