February is all about KOSTAL – and the PLENTICORE plus G2. The hybrid inverter has just received a performance update and has been available at a particularly attractive price point since the beginning of the year. This makes it an appealing choice both technically and economically for new installations and repowering projects (read more).
To mark our anniversary, “40 Years of EWS”, we are taking things one step further together with our partner for inverters, storage systems and e-mobility – with the following promotion:
The first 40 partner companies to place an order of at least four PLENTICORE plus G2 units in February 2026 will receive 4 PLENTICOINS free of charge (total value: at least €400).
Battery function included
With this promotion, the battery function for each purchased G2 model is effectively included for free. This is because still only 1 PLENTICOIN (instead of the original 3 PLENTICOINS) is required to activate the battery function on the G2.
Alternatively, you can also use the PLENTICOINS in the KOSTAL Solar Webshop to purchase activation codes for a power upgrade of the KOSTAL PLENTICORE G3 or to unlock the comfort function of the KOSTAL ENECTOR. Further details on PLENTICOINs, the single-purpose voucher, can be found on KOSTAL’s information page.
All terms and conditions in the anniversary calendar
Would you like to secure one of the 40 benefit packages? Full details of the promotion can be found in our anniversary calendar.
We offer the PLENTICORE plus G2 in six power classes ranging from 3 to 10 kW. For information on prices and availability, please visit our QuickShop.
Together with KOSTAL, we look forward to your participation!
