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.
