Step-by-step instructions
List modifications
Ask what was added or replaced, such as solar, lithium banks, inverters, air conditioning or satellite equipment.
Request diagrams and receipts
A good installation history includes component model numbers, wiring changes, fuse protection and installer details.
Look for visible warning signs
Note unsupported batteries, unprotected cable pass-throughs, inconsistent labeling and heat damage without opening energized equipment.
Verify normal operation
Ask the seller to demonstrate charging, inverter transfer, alarms and disconnects with a competent operator.
Get an independent review
A qualified marine electrician should assess high-current and AC additions before you rely on them offshore.
Safety note
Do not mistake a tidy cable bundle for evidence of safe circuit protection. Never remove covers from live panels during a showing.
Key takeaway
The best evidence of a good refit is both safe operation and clear documentation.
