System overview
The G3 PLENTICORE is a hybrid inverter that can be used as follows.
As a PV inverter
If the inverter is used as a pure PV inverter, only PV generators are connected to the DC inputs. There must be at least one PV generator connected to the inverter.
The energy generated can be used for self-consumption in the house grid or is fed into the public grid.

Hybrid inverter (product upgrade required)
If the inverter is being used as a hybrid inverter, PV generators and a battery are connected to the inverter.
For the battery to be detected at DC input 3, the battery function product upgrade must be activated in the inverter using an activation code.
The inverter is used to directly provide energy for self-consumption or to store surplus energy in the battery storage unit. The stored energy can be used for self-consumption in the house grid. Surplus energy that can no longer be stored is fed into the public grid.
In addition, energy from other AC energy suppliers (park controllers), e.g. PV systems, combined heat and power (CHP) units or small wind turbines, can be temporarily stored.

Battery inverter (product upgrade required)
If the inverter is being used as a pure battery inverter, there will be a battery connected to the DC 3 input only.
For the battery to be detected at DC input 3, the battery function product upgrade must be activated in the inverter using an activation code.
The inverter with connected battery storage is used to store energy from energy suppliers (park controllers) produced in the house grid, e.g., by other PV systems, combined heat and power (CHP) units or small wind turbines. The stored energy can then be used for self-consumption in the house grid.
There is the option to connect PV generators to the free DC inputs (hybrid inverter).

Product upgrades
Product upgrades can be activated using activation codes. This requires PLENTICOINs.
The PLENTICOIN is a single-purpose voucher for product upgrades. The PLENTICOIN can be redeemed in the KOSTAL Solar online shop against the required activation code (e.g. battery upgrade). The PLENTICOIN is purchased through specialist wholesalers.
The following product upgrades are available and can be obtained in the KOSTAL Solar Webshop using PLENTICOIN:
- Battery upgrade
Enables a battery to be connected to DC input 3. - Cable upgrade
Increases the basic power level of the inverter by up to two levels, e.g. 15 kW > 17.5 kW > 20 kW.
Power classes
The inverter is available in three sizes, S, M and L, with a basic power level of 4.0 to 20 kW.
The basic power level can be increased by two levels using an optional product upgrade (power upgrade) to make system planning as flexible as possible.
The power upgrade can also be done later, without having to replace the inverter.
The power activated in the inverter can be marked on the type plate. The activated power is also shown in the inverter's parameter report, available from the Webserver, and on the inverter's display.
Size | Basic power | Level 1 | Level 2 |
|---|---|---|---|
PLENTICORE S G3 | 4.0 | 5.5 | 7.0 |
PLENTICORE M G3 | 8.5 | 10 | 12.5 |
PLENTICORE L G3 | 15 | 17.5 | 20 |
