Where the all-in-one range meets the grid
The hybrid variants add what a grid-interactive site needs: CT sensing at the service entrance, load management, generator input, and on the LV models, three-phase output at 380 V from a 48 V battery.
That last point is the unusual one. Most three-phase systems in this power class use a high-voltage battery; running 380 V output from 48 V keeps the battery in the same ecosystem as the single-phase cabinets and avoids a high-voltage safety regime on a residential site.
Single-phase and three-phase
The single-phase variants cover 7.2 kW and 12 kW, with 10 kWh to 32 kWh. The three-phase LV variants run 12 kW and 15 kW with 16–32 kWh, and supply unbalanced loads — which is what a farm or a workshop actually has.

Applications
Grid-interactive homes
Charge from PV, hold a reserve for backup, and shift load into the evening peak.
Farms and workshops
Three-phase 380 V output from a 48 V battery, with unbalanced load capability for real site conditions.
Small commercial
12–15 kW with 21–32 kWh covers a shop, guesthouse or clinic with generator backup.
FAQ
What makes it hybrid?
It accepts grid, generator and solar inputs and manages all three, rather than only charging from PV and discharging to load.
Do the three-phase variants need a high-voltage battery?
No — they run a 48 V battery, which is unusual in this power class and avoids a high-voltage stack.
Can it run without the grid?
Yes, with generator support on the AC input. The transfer is automatic on the backup output.
Which variant for a house?
7.2 kW single-phase with 10–16 kWh for most houses; 12 kW with 21–32 kWh where there is an EV or a heat pump and electric cooking.
