The page adds a rough 8% VAT street price for mid-2026 Poland and checks inverter size and battery family. It is a shopping list sketch, not a quotation and not a design for your roof.

Prices are street sketches, not a shop. Models go out of stock. Cable length, earthing, a scaffolding day and the DSO application are not in the list. Pair families (Huawei+LUNA, Fronius+BYD, Sungrow+SBR) matter more than a bargain price.
