Hei

Tilasin teiltä KSB 31i aggregaatin, ja se saapui 8.6.2026.

Kone sinänsä toimii hyvin. Olen vain ihmetellyt sekä nettisivuillanne että koneen kyljessä olevia teholukemia, joissa ei tunnu olevan logiikkaa.

Nettisivulla (https://konner-sohnen.fi/products/inverter-generator-ksb-31i) moottorityypiksi ilmoitetaan KSB 210i ja sen tehoksi 5,4 hv. Suurimmaksi sähkötehoksi ilmoitetaan 3,0 kW. Olen tätä ihmetellyt jo pidemmän aikaa, että näin pienellä hevosvoimamäärällä saadaan tuollainen sähköteho aikaiseksi. Kuten hyvin tiedätte, kaikkien häviöiden jälkeen moottorin hevosvoimamäärä pitää olla reilusti kaksinkertainen saatuun kilowattimäärään nähden. Tässä tiedossa oli jotain kummallista.

Satuin nyt vertailemaan muita Basic -sarjan invertteriaggregaatteja ja hämmästyin erilaisia tietoja.

Koneelle KSB 28i annetaan seuraavat tiedot: moottori KSB 210i ja teho 7 hv.

Koneelle KSB 30i annetaan seuraavat tiedot: moottori KSB 210i ja teho 7 hv.

Eli kaikissa aggregaateissa on sama kone, mutta versiossa 31i olisi eri teho. Uskallan vahvasti päätellä, että teidän nettisivulla on KSB 31i:n kohdalla typo, kirjoitusvirhe. Hevosvoimien sijasta sinne on kirjattu teho kilowatteina. Ja sama virhe on tullut tuotantolinjalle tarraan, joka liimataan tuuletuskopan säleikön keskiöön.

Kaikki nämä huomiot on kerätty liitetiedostoon.

Parhain terveisin

je ne peux toujours pas utiliser mon produit : il m' a été livré sans son bouchon d'huile !!!!!!!!!!!!!!!

Von der ersten Beratung bis zur Lieferung hat alles hervorragend funktioniert. Das Verkaufsteam war sehr freundlich, kompetent und stets schnell erreichbar. Wir haben einen Notstromgenerator für Haus gekauft, die Lieferung erfolgte schnell und der gesamte Ablauf war unkompliziert und professionell.

Besonders erfreulich ist, dass auch unsere Nachbarn links und rechts aufgrund der positiven Erfahrungen ebenfalls Generatoren bei dieser Firma gekauft haben. Das spricht für die Qualität der Produkte und den hervorragenden Service.

Wir können diese Firma mit bestem Gewissen weiterempfehlen.

Vielen Dank, Alexander, für diese tolle Rückmeldung! Es freut uns sehr, dass Sie mit unserem Service und Produkt so zufrieden sind. Wir schätzen Ihr Vertrauen und Ihre Weiterempfehlung sehr. Wenn Sie in Zukunft weitere Unterstützung benötigen, sind wir gern für Sie da!
