Description
400W 12V TOPCon Monocrystalline Fixed Solar Panel
This 400W 12V TOPCon monocrystalline fixed solar panel is designed for compatible caravan, RV, 4WD, shed, cabin and off-grid installations requiring a rigid framed panel.
Check before ordering: the panel measures 1722 × 765 × 30mm. Confirm the available mounting area and that the controller or inverter can accept 27.13V open-circuit voltage and 18.97A short-circuit current.
Compare this model with other fixed, shingled, bifacial and portable options in StarPower’s 400W solar panel range.

Controller and Battery Compatibility
Check the controller’s maximum PV voltage, PV current limit and charging output before connection. The battery-charging profile must suit the battery chemistry. Browse MPPT solar charge controllers and lithium batteries.
For multiple panels, series wiring increases array voltage and parallel wiring increases current. Recalculate the complete array and use appropriately rated cable, connectors, fuses and isolation.
Suitable Applications
- Caravans and motorhomes with sufficient mounting area
- 4WD and camping battery systems
- Off-grid cabins, sheds and remote systems
- Ground-mounted solar arrays
Installation and Output
Use secure structural support and follow the installation instructions. Rated output is measured under standard test conditions; sunlight, temperature, shade, mounting angle, cleanliness, cabling and controller efficiency affect actual output.
FAQs
Can this panel charge a lithium battery?
Yes, when used with a compatible controller set to the correct lithium charging profile.
Is a regulator included?
No regulator is listed as included. Select a controller that is compatible with the panel’s voltage and current and the intended battery system.
