FREE System Voucher
As well as a free system design, we are giving away an Electrical System Voucher this Black Friday for you to spend on electrical components at Roamer.

You can put the money towards any products stocked by Roamer from leading brands Victron, Garmin Safiery, Blue Sea and many more. Also includes battery cables, fuses or isolation switches.
To take advantage of this fantastic deal to upgrade your electrical system, all you need to do is buy a Roamer battery before midnight on Monday 1st December. Minimum spend of £500 on system parts before System Voucher can be applied.
How does it work?
Roamer stock a wide range of Victron parts as well as solar panels, cables, fuses and everything else you need to install a complete off-grid electrical system. To take advantage of our Black Friday deal, simply follow the steps below:
Terms and Conditions
After completing your purchase of a Roamer battery, you will receive an email invitation to book your free consultation. If you haven't had an email after 24 hours (don't forget to check your junk folder!) please contact us on hello@roamer.com
The electrical consultation will be with one of the Roamer tech support engineers or system designers. Depending on your situation, the consultation will involve either:
30 minutes to chat about your existing electrics, answer any questions, recommend new upgrades, help you set up chargers or remotely configure Victron equipment (Cerbo GX required), or:
30 minutes to discuss a new electrical system based on Roamer and Victron components. We will also create a wiring diagram and a full parts list and provide a quote for all parts. Note that wiring diagrams can only be provided for new systems using Victron and Roamer, if you already have your components or wish to use other brands then we can discuss these and help you configure them to work with your battery but cannot provide a wiring diagram.
The value of the voucher will be calculated as 10% of the total amount spent on batteries via roamer.com during the sale period. There is a £500 minimum spend on other components but you can only use the voucher up to the value of the components purchased, there is no cash equivalent and if you do not use the full voucher then the unused balance left over will be cancelled. Standard prices and shipping charges apply.
Offer applies to batteries purchased via roamer.com only, trade accounts and purchases made via a reseller or installer are excluded.
The free electrical consultation has a normal value of £120 and is not redeemable for cash. The voucher can only be put towards products that Roamer stock and is not redeemable for cash.
The Black Friday/Cyber Monday deal applies to retail customers who purchase Roamer batteries between 00:01am 14th November 2025 and 23:59pm Monday 1st December 2025. The consultation must be booked for a date before 15th January 2026. The voucher must be redeemed before 23:59 on 31st January 2026.
