Description
The inverter sits between the high-voltage battery and the site grid and controls charging and discharging. It has no PV inputs, its three SUNCLIX ES DC inputs take batteries at 95–880 V with up to 68 A charge and discharge current. On the 3N~ 230/400 V side rated current is 36.3 A and maximum 40 A, with efficiency up to 98.3 % in both directions. When the grid fails it switches to three-phase backup at 25 kVA and delivers 27.6 kVA for at least 5 s to cover motor inrush. Changeover takes under 30 s with an automatic backup box and under 10 s with the Auto BackUp Switch. A capacity of 5 kWh suits a private house, 230 kWh is already commercial storage, and one unit type covers both cases. The IP65 housing weighs 22.3 kg and runs at −20…+60 °C.
How to choose
The deciding figure is discharge and backup power, 25 kW per unit with a charging rate above 1C where the battery accepts it. If PV inputs and a battery are wanted in one housing, take the PLENTICORE G3 hybrid in class L at 15–20 kW. Retrofitting storage of 5.1–66 kWh to a small home PV plant only needs the PLENTICORE BI. On a large site the generation stays with PIKO CI 30 / 50 / 60 grid-tied inverters at 33–66 kVA.

FAQ
What backup power does the PLENTICORE BI 25 deliver?
Three-phase backup at 25 kVA continuous and 27.6 kVA at start-up for at least 5 s.
What battery capacity does the PLENTICORE BI 25 support?
A system with this inverter can range from 5 to 230 kWh, with batteries wired to its three DC inputs.
Can low-voltage batteries be used with the PLENTICORE BI 25?
No, only high-voltage batteries with a total of 5–230 kWh are listed, at 95–880 V.
Which breaker protects the PLENTICORE BI 25 output?
A B40 or C40 breaker, since maximum output current is 40 A against 36.3 A rated.
Can PV modules be connected to the PLENTICORE BI 25?
No, all 3 DC inputs are meant for batteries. The modules feed a separate grid-tied or hybrid inverter.
