Is Sunstore a Legitimate UK Company?
Yes. Sunstore Solar is a legitimate UK solar business trading through SUNSTORESOLAR LTD, an active company registered in England and Wales under company number 07814446.
The company was incorporated in 2011 and operates from a physical base in Goring-by-Sea, Worthing, West Sussex, where it provides sales and technical support alongside its off-grid solar business.
Sunstore specialises primarily in off-grid solar systems, including equipment for homes, cabins, workshops, campervans and motorhomes. Its range includes complete solar kits, batteries, inverters, charge controllers and pre-wired system options.
There are several useful trust signals for buyers:
- Active UK-registered company
- Physical business address in West Sussex
- Operating since 2011
- UK-based phone and email support
- Established off-grid solar product range
- Independent customer feedback
- Long-standing involvement in leisure-vehicle solar installation
These factors don’t automatically mean Sunstore will be the right supplier for every project, but they do make it very different from an anonymous marketplace seller or short-lived online solar brand.
What Does Sunstore Sell?
Sunstore specialises in off-grid solar equipment and complete solar kits, with systems ranging from small remote-power setups through to larger installations for cabins, workshops and off-grid homes.
Its current range includes:
- Off-grid home solar systems
- Solar kits for cabins, sheds and workshops
- Campervan, motorhome and caravan solar kits
- Solar panels
- Lithium and other battery-storage options
- Inverters and MPPT charge controllers
- Victron Energy equipment
- Pre-wired solar systems
- Cables, mounting equipment and other accessories
If you’re looking at vehicle solar, see our Sunstore 100W Solar Vehicle Kit review for a closer look at one of its smaller campervan and motorhome systems.
One of Sunstore’s main advantages is that buyers can choose between individual components and more complete system packages. Pre-wired options can also reduce some of the electrical assembly involved in building an off-grid system from separate parts.
For anyone still deciding how much solar capacity they actually need, it makes sense to size the system first rather than choosing a kit purely on price or headline wattage.
What Are Sunstore’s Kits Like?
Sunstore’s kits are generally aimed at buyers who want a more complete off-grid system rather than piecing everything together from separate marketplace components.
Depending on the system, its kits can include:
- Solar panels
- MPPT charge controllers
- Inverters
- Lithium or other battery options
- Cables, protection and connectors
- Pre-wired equipment boards
- Mounting hardware and accessories
Sunstore also uses established third-party equipment across parts of its range, including Victron Energy components. The exact panel, inverter, battery and controller supplied can vary between systems and according to availability, so it is worth checking the full component list before ordering.
For a larger fixed setup, see our Sunstore 4800W Deluxe review for a closer look at one of its higher-capacity off-grid systems.
Pre-Wired Options
One of Sunstore’s more useful features is its range of pre-wired systems. These can remove some of the complexity involved in assembling controllers, inverters, fuses and other equipment from individual parts.
They are still proper electrical systems rather than completely plug-and-play appliances, so larger installations may require suitable electrical knowledge or professional help.
Support Is Part of the Appeal
Where Sunstore differs most from cheaper mass-market kits is the level of UK-based technical support available when choosing and setting up a system.
That can be particularly useful if you are unsure about:
- System sizing
- Battery capacity
- Inverter requirements
- Cable sizes
- Component compatibility
- Expanding the system later
For buyers who already know exactly what components they want, there may be cheaper ways to build an off-grid system. For anyone who values system guidance, pre-wired options and UK support, Sunstore has a clearer advantage.
Customer Service & Reviews
Customer support is one of Sunstore’s stronger selling points, particularly for buyers who are new to off-grid solar or need help choosing compatible components.
Sunstore provides UK-based phone and email support before and after purchase, covering areas such as system sizing, battery capacity, wiring and component compatibility.
Independent customer feedback is generally positive, with recent reviews frequently mentioning:
- Helpful technical advice
- Support with system sizing and setup
- Clear communication
- Well-packaged orders
- Assistance when problems arise
The overall review volume is relatively modest compared with large national retailers, so I wouldn’t judge Sunstore purely on a headline star rating. However, the pattern of feedback supports its reputation as a specialist supplier where technical support is part of the service.
Delivery, Returns & Warranties
Sunstore’s policies are fairly straightforward, but larger off-grid systems can have different lead times and warranty terms from smaller stocked products.
| What to Check | Current Position |
|---|---|
| Standard delivery | Typically 1–3 days for qualifying stocked orders |
| Larger systems | Lead times can be longer depending on stock and system size |
| Returns | 30 days for eligible unused goods returned in new condition |
| Return costs | Original delivery and return postage are generally not refunded |
| Product warranty | At least 1 year, with longer cover on some components |
| Victron equipment | Many controllers, chargers and inverters carry 5-year warranties |
| Workmanship | Sunstore states a 2-year workmanship guarantee for work carried out at its workshop |
Warranty length should always be checked against the exact components in the system. Panels, batteries, inverters and controllers can each have different manufacturer cover, so avoid relying on one headline warranty figure for the whole kit.
For larger systems, it is also worth confirming lead time and stock availability before ordering, particularly where specific panels, batteries or pre-wired assemblies are required.
Who Is Sunstore Best For?
Sunstore is best suited to buyers who want specialist off-grid equipment with UK-based technical support, rather than simply choosing the cheapest kit available.

Final Verdict: Is Sunstore Legit?
Yes. Sunstore Solar is a legitimate UK solar supplier with an active registered company, a physical West Sussex base, established off-grid product range and UK-based technical support.
Its main strength is not being the cheapest option. It is the combination of off-grid specialism, system guidance, pre-wired options and support before and after purchase. That makes it particularly well suited to buyers who want more help than they would typically get from a budget marketplace kit.
For straightforward off-grid projects, cabins, workshops, campervans and larger systems, Sunstore is a credible supplier worth considering. Just check the exact components, lead time and warranty terms before ordering.
