Recommendations use Victron's continuous output rating at 25°C (77°F). Engine rooms and lazarettes run hotter than that, and output drops as temperature rises, so we size new installs with about 25% headroom over the loads you tick.

• Sizes and weights for Victron units come from Victron datasheets. Older units use manufacturer or dealer specs.
• The fit check compares box dimensions only. Leave room for cable bends, airflow and service access, and measure before you buy.
• Wattages for appliances are typical figures. Check the label on yours if you're close to a size limit.
• Prices and stock are from onboardmarinegoods.com and may change. The product page is always current.
