Before you start
Gather the appropriate supplies and review the specific equipment manual.
- Marina electricity tariff
- Shore power meter
- Appliance energy data
Step-by-step instructions
Identify the billing method
Check whether electricity is included, metered per kWh or subject to minimum charges and local taxes.
Measure the largest consumers
Air conditioning, water heaters, dehumidifiers and battery charging often dominate AC energy use.
Compare charging losses
Shore charger and inverter losses can make wall energy consumption higher than stored battery energy.
Estimate daily use
Multiply average appliance kWh by expected days and compare with the marina rate.
Review invoices
Track unexpected increases and inspect appliances or ask the marina to verify meter readings where appropriate.
Safety note
Never use unapproved shore-power adapters or exceed a pedestal rating to support heavy AC loads.
Key takeaway
A little energy tracking can prevent marina utility bill surprises.
