You have a technical question ? We have your answer ! (FAQ)

Dolphin Charger has manufactured marine battery chargers since 1996, so we know what technical questions arise when purchasing, installing or using a boat battery charger or inverter, or any power supply unit onboard ships and vessels.

Since 1996, Dolphin Charger has manufactured and distributed tens of thousands (over 100.000 units, actually) of boat battery chargers and marine inverters. Our Client Service has been of assistance to hundreds of professional customers (distributors, marine electricians, ship builders…) and end-users (boat captains, pleasure boat owners…) such as yourself.

We have collated all their queries into a very hands-on « FAQ » for your own ease of use. This FAQ features questions and answers about « Sizing : chosing the right equipment » ; « Installation : mount and cabling » ; « Charging advices » ; and our « Warranty » policy.
