Wiring Unlimited - instructive book from Victron Energy

Victron Energy has published a free book full of useful information about electrical wiring of batteries, inverters, battery chargers and inverter/chargers. 
The book puts the emphasis on 'correct' wiring of systems to prevent problems at a later stage. Wiring faults often cause an energy system to underperform or even not work at all. 
This book is intended for anyone involved in the development, installation, commissioning or troubleshooting of a DC/AC energy system.
