What this video covers
The electrical system upgrade on a 1988 Irwin involves replacing three 20-amp-hour AGM house batteries with a 460-amp-hour Epoch lithium battery and installing a Victron energy system.▶ 18:39 The installation includes a Lynx shunt, Lynx distributors, and a MultiPlus 3000-watt inverter-charger.▶ 1:10 Wiring requires custom-length two-aught cables, which are crimped and heat-shrunk rather than soldered to prevent connection failure from heat.▶ 1:26 A significant challenge involves sourcing metric-sized lugs compatible with Victron equipment, as standard US hardware stores often stock only imperial sizes.▶ 14:21 The project also integrates 1,000 watts of solar power through multiple MPPT controllers, with a disconnect switch installed in the lazarette for maintenance.▶ 11:04 Programming the lithium battery requires technical support from the manufacturer to enable discharge settings.▶ 16:28 The final configuration separates the house lithium bank from the AGM starting and windlass batteries, with the alternator wired to charge both engine-related batteries.▶ 18:58
