This complete 200W off-grid solar charging kit pairs a high-efficiency monocrystalline solar panel with the industry-leading Victron SmartSolar MPPT 75/15 charge controller, giving caravans, motorhomes, boats and cabins a reliable way to keep a 12V leisure battery topped up without mains power. The panel's multi-busbar cell design extracts more current from the same cell area, while its wider, lower-profile 1038 x 992mm footprint and 8 pre-drilled mounting holes make it straightforward to fit securely to a roof or deck without a separate bracket kit.
The panel is supplied pre-wired with 90cm of solar cable and MC4 connectors, with a further pair of 5m MC4 extension cables included to reach the SmartSolar controller wherever it's best sited, plus a mounting set and fused battery cable to complete the installation. The controller then intelligently tracks the optimum power point to extract the maximum usable charge from the panel across the day, from early morning through to low-angle winter sun.

Battery Compatibility
Informational — Wide, Low-Profile Panel Shape
At 1038 x 992mm, this panel is noticeably more square in shape than a typical elongated 200W panel, which can suit roof layouts where a long, narrow panel wouldn't fit well — for example alongside roof vents, aerials or skylights on a caravan or motorhome roof. Check available roof space against these dimensions before ordering.
Safety — Charge Controller Required
This solar panel must never be wired directly to a battery. The panel's open-circuit voltage will overcharge and damage an unregulated 12V battery. It must always be connected through the supplied Victron SmartSolar MPPT 75/15 charge controller, which manages the charging profile safely.
Why This Kit Works Well Together
Pre-Drilled Mounting Holes for Simple Fitting
Eight factory-drilled mounting holes let the panel be bolted directly to a compatible roof rail or bracket system without needing to drill the frame yourself, speeding up installation for both DIY and trade fitters.
True MPPT vs Basic PWM Regulation
The SmartSolar MPPT 75/15 continuously hunts for the panel's maximum power point rather than simply clamping voltage like a cheaper PWM controller, converting a larger share of the panel's rated output into usable battery charge throughout the day.
Multi-Busbar Cell Design
The panel's multi-busbar cell layout reduces internal resistance losses and extracts more current from the same physical cell area, helping the panel perform better in the warmer ambient temperatures often experienced on vehicle and boat roofs.
Bluetooth Monitoring Without Extra Hardware
The SmartSolar controller's built-in Bluetooth lets you check state of charge, charging stage and daily yield from the free VictronConnect app on a phone or tablet, with no separate display unit or monitoring shunt required.
Adaptive Multi-Stage Charging
A temperature-compensated bulk, absorption and float charging profile is applied automatically, protecting battery health over repeated charge cycles rather than simply pushing a fixed voltage at the battery regardless of its condition.
Wide Format Suits Constrained Roof Layouts
The panel's wider, shorter profile can be easier to position around roof-mounted obstructions such as vents, aerials and skylights than a single long, narrow panel of equivalent output.
Suitable For
- Motorhomes and campervans needing dependable off-grid charging for lighting, USB devices, water pumps and a small 12V TV.
- Caravans and static holiday homes that need a maintenance-free way to keep a leisure battery charged between trips.
- Canal boats, narrowboats and liveaboard vessels where quiet, fuel-free charging is preferred over running an engine or generator.
- Garden offices, sheds, cabins and small off-grid setups running from a single 12V battery bank.
- Installations where roof space is a squarer or more constrained shape, where a wider, shorter panel profile fits more easily than an elongated one.
What's Included
- 1 x 200W monocrystalline solar panel with 90cm pre-fitted solar cable and MC4 connectors (SWG-200M).
- 1 x Victron SmartSolar MPPT 75/15 Retail charge controller with Bluetooth.
- 1 x Mounting set with 4 plastic corner brackets, 2 side brackets and a 3–7mm double-entry cable gland (SET_BR).
- 1 x pair of 5m 4.0mm² solar extension cables with MC4 connectors on one end and bare cable on the other, for connecting the panel to the charge controller (5QM40).
- 1 x 5m dual-core 6.0mm² battery cable with a 20A fuse fitted in a fuse holder, for connecting the charge controller to the battery (BCAB560FH).

Compatibility Note — Panel Voltage vs Controller Rating
A single panel from this kit runs well within the controller's 75V maximum PV input, giving headroom should the system later be expanded with a second panel in series. Always recalculate combined Voc against the controller's 75V limit — particularly in cold weather, when open-circuit voltage rises — before adding further panels.
Frequently Asked Questions
Why is this panel a different shape to other 200W panels?
At 1038 x 992mm, this panel is closer to square than the more common long, narrow 200W panel format. This can make it easier to fit onto roof space that's constrained in length but has more width available, or where a longer panel would clash with existing roof fittings such as vents or aerials.
Can this kit charge a 24V battery system?
The SmartSolar MPPT 75/15 auto-detects and supports both 12V and 24V battery banks. However, this panel is rated for 12V nominal use; for a 24V system you would typically wire two panels in series, keeping the combined open-circuit voltage safely under the controller's 75V limit.
Does this kit include everything needed to mount the panel?
Yes. The panel has 8 pre-drilled mounting holes in its frame, and the kit also includes a mounting set with 4 plastic corner brackets, 2 side brackets and a 3–7mm double-entry cable gland for a weatherproof cable pass-through.
How do I monitor the system once it's installed?
The SmartSolar MPPT 75/15 has built-in Bluetooth, so you can pair it with the free VictronConnect app on a smartphone or tablet to view real-time charging data, battery voltage, daily energy yield and historical charging stage information — no separate display or shunt is required.
What size battery bank can this kit support?
A 200W panel through a 15A MPPT controller is well suited to leisure battery banks up to around 250Ah at 12V for light-to-moderate daily loads such as LED lighting, USB charging, water pumps and a small 12V TV. Larger banks or heavier daily loads may benefit from an additional panel.
Is the panel waterproof and suitable for permanent outdoor mounting?
Yes. The panel uses a sealed, tempered glass front, an anodised aluminium frame and a waterproof construction rated for permanent outdoor use in all UK weather conditions, making it suitable for year-round mounting on a vehicle roof, boat deck or cabin.
