Questions about the promotion

Frequently asked questions about the Golden October Deals

Answers about discounts, expansion and included items.

Which BK products take part in the promotion?

Marked BK products receive a 10 % extra discount. The extra discount increases to 15 % for eligible order values of €2,799 or more.

How is the extra discount calculated?

Where can I see the final promotional price?

The applicable extra discount and final promotional price are shown at checkout.

What is the difference between BK215 PLUS and B215 PLUS?

The BK215 PLUS main storage unit is the system base. B215 PLUS is a compatible expansion battery that adds capacity, but does not automatically increase output power.

Can I expand an existing BK storage system?

That depends on the exact model, hardware version and approved configuration. Check the compatibility information or ask DRBO Greenenergy to check your system before ordering.

Which extra discount applies to sets?

The extra discount applies only to marked BK products and sets. The information on the respective promotional product applies.

What role does EV3600 play in the BK system?

EV3600 is a bidirectional inverter for compatible systems in the BK215 and BK215 PLUS ranges. Available functions and required accessories depend on the selected configuration and current manufacturer approval.

Is EV3600 included in every BK set?

No. EV3600 is available individually and in selected sets. Check the included items for the specific product variant before ordering.
