Inverter generator KS 4000iE S

Q: Are there inverter generators that start themselves when the power goes out in the house?

Yes, the Könner &amp; Söhnen KS 4000iE S and KS 6000iE S inverter generator models fully support the function of automatic backup in case of power failure. Despite the fact that the official article of these models does not contain the abbreviation ATSR, they are structurally equipped with a special 8-pin ATS connector on the control panel and have a built-in electric starter. To build a full-fledged auto-start system and ensure uninterrupted power supply to the house, the Könner &amp; Söhnen KS ATS 4/25 Gasoline automation unit is connected to these generators.The principle of operation of such a connection is fully automatic: as soon as the power supply to the house disappears, the ATS unit instantly reacts, starts the engine and switches the house&#39;s power supply to the generator. When the electricity supply from the central network is restored, the automation independently turns off the generator and imperceptibly transfers the object to the main line. This provides maximum comfort, because you do not have to go outside to start the system yourself.

*** Fuel consumption depends on many factors, such as load, fuel quality, season, altitude, technical condition of the generator.

ATTENTION! The product is sold without engine oil or gasoline. Before the first start, engine oil for four-stroke gasoline engines must be added. We recommend 10W-30 or 10W-40 oil. Always check the oil level before each use. Use only unleaded gasoline with an octane rating of 90–95 containing no more than 10% ethanol.

Leider war die Angabe " auslieferung ohne Motoröl" falsch. Somit durfte ich Die Hälfte wieder absaugen.
Augenscheinlich ein sehr gutes Gerät.
Nach einigen Jahren könnte ich mehr sagen.
Augenscheinlich ein deutsches Produkt.
Aber produziert wird es laut KI im Ausland, gelagert in Polen und von da versendet.
Das ist leider auf der Website nicht erkennbar.
Die innovative Entwicklung scheint aber tatsächlich deutsch zu sein.

Alles funktioniert super! Schnelle Bearbeitung und Liferung!

Voor de Nederlandse handleiding.
Scroll helemaal naar beneden en de handleiding staat helemaal linksonder.

Заказ отримали, дякую велике

Accu is goed bereikbaar.
2 schroeven losdraaien, kap verwijderen.
Accu zit direct rechtsonder je kunt er zo bij.
U wou een stille aggregaat daarom zitten er kappen omheen. Ik vind uw opmerking niet passend !

Frequently Asked Questions

The 4.0 kW inverter easily copes with the starting loads of household appliances. It is designed for the simultaneous operation of the heating system of the house, a pumping station, a large refrigerator, a TV and a router. In addition, the power reserve allows you to start a washing machine (in the mode of quick washing in cold water or washing without strong heating). Also, the generator power is enough to turn on a regular air conditioner in the heat to cool the room or use a microwave or hairdryer while other appliances are resting.
