Start with the loads and installation assessment, then shortlist equipment.
List what needs electrical power
Create a list of the appliances and systems you intend to run, including which are used together. Give the list to a marine electrical specialist and ask them to assess the relevant demand and starting requirements. Avoid choosing a generator from the boat’s length alone. Explain whether the aim is occasional charging support, extended time away from shore power or a different operating pattern.
Review the installation with specialists
Discuss available space, service access, cooling, exhaust, fuel supply and the boat’s electrical arrangement with the installer. A generator is part of several connected systems, so a catalogue output figure cannot establish suitability. Ask the supplier to identify every installation assumption. Nanni lists marine generator equipment alongside propulsion products, providing a route to a model-specific discussion.
Compare the supported package
Request a quote for the complete commissioned installation, including controls and any required changes to associated systems. Ask about local service access, parts availability and the exact operating and maintenance documents. Confirm who will demonstrate normal operation and explain the installation at handover. Keep the electrical assessment and final equipment schedule with the boat’s records.
