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
7.68Kwh Off-Grid Power System
7.68kWh of lithium, a 3,000W inverter, a 60A MPPT controller and a battery monitor. Two 300Ah packs — a week of genuine autonomy for a full-time motorhome, with the charging and monitoring already specified.
- 7,680Wh, two 300Ah LiFePO4 packs
- 3,000W inverter, 6,000W surge, 90% maximum efficiency
- 60A Rover MPPT controller and battery monitor
- Battery 150A continuous charge, 200A continuous discharge
- Each battery 384 × 194 × 253mm, 25.0kg, IP65
- Optional 4 × 200W ShadowFlux panels
A properly balanced system
The ratio matters more than any single number. 7.68kWh of storage, 800W of optional array and a 60A controller means solar can realistically refill the bank in summer, while the 300A of combined charge acceptance means an alternator or mains charger can do it in winter. That balance is what the individually-bought systems usually get wrong.
The battery monitor is the part people skip
A shunt-based monitor tells you state of charge from actual coulombs in and out, not from resting voltage — which on lithium is nearly flat across the whole usable range and therefore useless as a fuel gauge. Included here rather than bought later.
Before you order
Two 300Ah packs is 50kg of battery before the inverter, controller and any panels. Check the payload. The inverter works between 0°C and 40°C and shuts down below 10V DC, so it wants to live inside the insulated space.
