Shop caravan and RV solar gear to keep your batteries topped up when you’re off-grid. Solar is ideal for running everyday 12V loads like lights, pumps, fans and device charging, especially when you’re parked up for a few days.
To choose the right solar setup, start with your battery system (usually 12V) and your battery type (AGM or Lithium). Then match your solar controller/regulator to your panel input and battery profile. In many setups, an MPPT controller is the most efficient option, especially when panel voltage is higher than battery voltage.
If you’re adding or upgrading solar, also consider cable size, connector type, fuse protection, and where the panels will be mounted (roof vs portable). If you’re unsure, checking your current controller model and battery type is the quickest way to choose compatible parts.
It depends on what you run each day and how long you want to stay off-grid. As a rough guide, higher daily usage (fridge, lots of lighting/device charging) needs more panel capacity and adequate battery storage. The goal is to replace what you use each day, not just “top up”.
MPPT regulators are generally more efficient and usually harvest more power from your panels, especially in cooler weather or partial shade. PWM regulators are simpler and cheaper, but can be less efficient. For most caravans, MPPT is a solid upgrade.
Yes—but you need a controller/regulator that supports lithium (LiFePO4) charging profiles or adjustable settings. Always confirm your controller is compatible with your battery type before installation.
Fusing is recommended to protect wiring and the system, especially on runs from roof panels to the controller. The correct fuse and placement depends on panel output and cable size—protect the cable and place protection as close to the source as practical.
Common causes include shading, dirty panels, loose connections, undersized cable, a controller set to the wrong battery type, or a blown fuse. Start by checking the controller display/settings, then inspect wiring and connectors.
Roof solar is always working when there’s sun and is convenient. Portable solar can be positioned in full sun while your van sits in shade. Many people use a combination depending on travel style.
It depends on the setup. Roof panels often use MC4-style connections into the controller. Portable panels may use Anderson-style plugs. Match what you already have and confirm polarity before connecting.
