What is Wiring Unlimited?

A Victron Energy book by Margreet Leeftink, Information Developer for Victron Energy B.V.

Wiring Unlimited is all about electrical wiring of systems containing batteries, inverters, chargers and inverter/chargers – and going by the testaments on the Victron Community, an invaluable resource.

Wiring Unlimited’s primary purpose is to aid in the understanding of the basic principles behind certain electrical concepts and how they apply to Victron Energy products and the installation of such products.
