How buying this works
Roam Wired does not stock this item. The button above hands you over to the seller's own shop, where you place the order, pay and arrange delivery directly with them. Nothing is added to a Roam Wired basket, and we never see your payment details.
We list it because it is the part our calculator would specify for a build like yours, not because we make the most on it. How we make money
Delivery and returns
Delivery cost, delivery time and the returns window are set by the seller, not by us, and Roam Wired's own £10 / free-over-£250 UK delivery does not apply here. Check their delivery and returns terms on their product page before you order.
Your consumer rights, including the 14-day right to cancel a distance sale, are against the seller who took your order.
Warranty and support
The manufacturer's warranty is handled by the seller you buy from. If something fails, raise it with them and quote their order number — we cannot open a claim on your behalf.

Overview
15.36kWh Off-Grid Power Kit
15.36kWh of lithium and a 3,000W inverter. Four 300Ah Core Mini packs — the largest storage kit Renogy list here, and genuinely more than most conversions will ever need.
- 15.36kWh of LiFePO4 storage, four 300Ah packs
- 3,000W inverter, 6,000W surge, under 50ms mains transfer
- Battery monitor included
- Optional 4 × 200W ShadowFlux panels
- Each battery 384 × 194 × 253mm, 25.0kg
- Battery max continuous discharge 200A, 380A peak for 10s
Who this is really for
Not a panel van. Fifteen kilowatt-hours suits an off-grid cabin, a mobile workshop, a film unit vehicle or a large motorhome running air conditioning — applications where the load is genuinely high and the vehicle can carry 100kg of battery. For a two-person conversion, the 10.24kWh kit is already generous and the 5.12kWh systems are the sensible starting point.
The weight is the constraint
Four 300Ah packs is 100kg of battery alone. Before anything else, check the remaining payload on your chassis and plan where that mass sits — low, central, and properly restrained on all axes.
Before you order
Renogy offer this with and without solar, and the components differ between configurations. Confirm on their page exactly what your chosen variant includes — in particular whether a charge controller is part of it — before ordering.
