B) What is the real risk
C) Will anything prevent it actually charging
D) If you have a virtually flat battery in a storm, what should you do if you need to keep driving!

It then lists three methods, any one of which could be used. Fitting an earth rod is the most cost-effective and quickest way to comply with regulation 722.411.4.1.
Other methods include fitting a costly isolation transformer and incorporating special circuitry in the charger which monitors the incoming supply and disconnects the charger including the earth path if a fault condition is detected, the version 2 of my zappi charger has this functionality.
