The EcoFlow setup
The power setup centers on a purchased EcoFlow DELTA Pro 3, an expansion battery, and a separate 12 V DC fuse panel.
EcoFlow's US product page, reviewed on 2026-09-21, lists the DELTA Pro 3 base unit at 4096 Wh and describes the base-plus-extra-battery bundle as 8 kWh of storage with 4,000 W of output. Storage capacity is energy, measured in Wh or kWh; the inverter's output rating is power, measured in W. These are manufacturer ratings, not physically verified as-built capacity or output.
The receipt describes the base unit as 4000 Wh and the expansion battery as 4096 Wh. Physical labels and exact owned models still need confirmation against the manufacturer's specifications. A separate DCHOUSE 12-way fuse panel is owner-reported, but its exact SKU and the installed wiring path are unconfirmed. A purchase record does not establish a completed or tested installation.
Before relying on this setup, the battery connections, mounting, ventilation, charging paths, 12 V distribution, and protection need documentation and qualified review. The product link identifies the DELTA Pro 3 family; it does not establish compatibility or safety of the van's installation.
This is a record of the build, not an installation guide. Reported completion does not establish inspection, structural adequacy, or safety.

This is the shared electrical installation bundle also referenced in the solar, heater, and shore-power stories. It includes the power station and expansion battery, but no EcoFlow-only labor allocation or completed-system verification is inferred.
A shared bundle is not an additional charge for every system. Where repeated across stories, it refers to the same recorded charge; do not add those repeated references together.
Recorded line amounts, not a current quote or a complete installation total. Discounts and tax remain unallocated; no grand total or per-system labor split is inferred.
