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
12V 50A Dual Battery Charging 200W Solar Flex Bundle
A 50A dual-battery charger with MPPT solar input, bundled with a 200W flexible panel. The bigger version of the same idea — enough alternator current to genuinely refill a 200Ah bank on a driving day.
- 50A DC-DC charging from the alternator
- Trickle charges the starter battery as well as the leisure bank
- MPPT solar input built in
- 200W flexible panel included
- Charges while driving and while parked
50A changes what a drive is worth
At 50A you are putting roughly 600Wh into the bank for every hour of driving. A two-hour trip is most of a day's consumption replaced — which between November and February, when 200W of roof produces very little, is what actually keeps a conversion running.
Check the alternator and the battery
Fifty amps at the leisure end means appreciably more drawn from the alternator once cab loads are added, so confirm your alternator has the headroom. Also check the battery: several packs cap charge current at 100A across all sources, so a 50A charger plus a large array can approach that limit.
Before you order
The 200W flexible panel is a meaningful contribution in summer and a modest one in winter. If your roof can take rigid panels, they will outlast and outperform the flexible one — but the bundle is a tidy, single-order way to get a complete charging system.
