What this video covers

Disable the inverter function of an inverter/charger when leaving a boat unattended at a dock.0:32 If shore power fails, an enabled inverter will automatically draw from the battery bank to power AC loads, potentially depleting and permanently damaging expensive battery banks within a short period.1:59 While the inverter component must remain off, the charger component should stay enabled to maintain battery health while connected to shore power.1:28 Boat owners should inspect their vessels at least once a month to verify shore power connectivity, monitor bilge activity, and ensure dehumidifiers are functioning.2:57 Frequent checks help mitigate the risk of catastrophic battery failure and other winter storage issues. Disabling the inverter prevents the unit from draining batteries during an unexpected shore power disconnection.0:57
