Electrical Bench

Battery, charge and heater bays under the bench seat.

Story

The bench brings the van’s storage, charging, conversion, distribution and monitoring hardware together in one place. Two 12 V, 400 Ah EG4 LL batteries make an 800 Ah bank, alongside the Lynx Shunt and Distributor, 3,000 VA MultiPlus-II, SmartSolar MPPT 100/50, Orion XS 12/12-50, Cerbo GX MK2 and GX Touch 50.

It accepts 480 W of solar, alternator charging through the Orion, and 30 A / 120 V shore power through the MultiPlus. From there, the WFCO and Blue Sea panels distribute AC and 12 V circuits; the electrical documentation tracks 52 loads and their routes.
