System overview
The PLENTICORE plus G2 is a three-phase hybrid inverter that can be used in three-phase grids.
The inverter 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.

As a hybrid inverter (product extension 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 the DC input for the battery, 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.

Product extensions
Product extensions can be activated using activation codes. PLENTICOINs are required for this.
The PLENTICOIN is a single-purpose voucher for product extensions. The PLENTICOIN can be redeemed in the KOSTAL Solar Webshop for the required activation code (e.g. battery extension). The PLENTICOIN is purchased from specialist wholesalers.
The following product extensions are available and can be accessed with the PLENTICOIN in the KOSTAL Solar Webshop:
The product upgrades can then be activated using the KOSTAL Solar App, the inverter display or the inverter Webserver by going to Additional options and entering the activation code.
- Battery upgrade
Allows a battery to be connected to the DC input for the battery.
