Recommended as an install on any generator line, or any AC power line that may have occasional and unfortunate spikes - crucial for protecting your 240V appliances.

Designed to offer a 'safe' discharge route in the event of an alternator spike (IE when a battery charge event is interrupted with a fuse blowing).

Does not, on its own, make a direct alternator/lithium connection suitable. We always recommend battery to battery chargers for that!
