PLENTICORE BI battery inverter for AC-coupled storage
Country: Germany · Model: PLENTICORE BI
The PLENTICORE BI battery inverter, rated 5.5 or 10 kW, adds 5.1–66 kWh of high-voltage storage to a PV plant that is already running. It connects to the AC grid in parallel with the existing plant, so the original inverter and modules stay in place.

Description
AC coupling leaves the DC side of the running plant untouched, so the retrofit needs no equipment swap. The battery connects to one DC input with SUNCLIX connectors, at 120…650 V and 26 A charge and discharge current. That is where the model names come from, as BI 5.5/26 and BI 10/26 give power in kW and battery current in amps. On the grid side it connects 3N~ 230/400 V, with 7.94 A rated current on the smaller model and 14.43 A on the larger. Power flow metering and charge control use data from the Smart Energy Meter, and the battery link runs over RS485. Efficiency is 96.6–96.7 % battery to grid and 96.8 % grid to battery. The IP65 housing weighs 17.9–19.9 kg and runs at −20…+60 °C. It suits a plant built first, with storage added later.
How to choose
Choose the model by discharge power, 5.5 or 10 kW, and size the battery separately within 5.1–66 kWh. Three-phase backup and capacity up to 230 kWh call for the PLENTICORE BI 25 at 25 kW with 25 kVA backup. When the PV plant is still on paper, it is simpler to fit a PLENTICORE G3 hybrid at 4–20 kW or a PLENTICORE plus with its 7.5 kW battery DC channel from the start.
