GreenAkku – Victron Energy powered Tiny House

Victron Energy dealer Bosswerk GmbH & Co. KG or GreenAkku as they are usually known are based in Nettetal, about 30km West of Düsseldorf. They have developed the Tiny House you see in the photo above.

GreenAkku will be attending Caravan Salon Düsseldorf 2018 in FG Hall 11/11-03 later this week, between Aug 25th – Sep 2nd, where their Victron Energy powered Autarkes Tiny House will be on show.

Additionally Victron Energy’s display will be in Hall 13/D82 and Victron Energy dealer Accusysteme Transwatt GmbH will be in Hall 13/E64.

If you are not familiar with the tiny house movement then I’d like to refer you to an earlier blog which explains all: At home with Victron Energy – The Tiny House revolution

If you are familiar with Tiny Houses then why not jump right in and check the spec of GreenAkku’s fully loaded Autarkes Tiny House.

Self-sufficient Autarkes Tiny House – micro living without loss of comfort

Exterior construction & weights

This lightweight construction method ensures a payload reserve for the installation of furniture and technology, without exceeding the maximum permissible payload of 3.5t. The permissible gross weight of 5.4t ensures a safety reserve even with full tanks, by utilising 3 axles rated at 1,800kg each from Knott GmbH.

Exterior & interior dimensions

Interior accommodation & facilities

 

 

Water

500l fresh water tank, pressurised water system and rain collection system – where rainwater landing on the roof is passed via 2 pipes into the tank.

It’s clear that if you  can manage to get along to Caravan Salon Düsseldorf 2018 there are multiple stands showing Victron Energy products and interesting implementations of those products, for exciting leisure activities – such as energy self sufficiency in a Tiny House. Worth a visit I’d say.
