Delivery options to:
Choose countryThe ALLPOWERS SP037 is a portable 400 W solar panel for charging portable power stations when camping, travelling in a motorhome or staying off-grid. Its five connected segments fold for transport, with an integrated handle for carrying.
Positioning and energy generation
Adjustable supports let you set the panel's angle towards the sun. The polycrystalline silicon cells have a declared efficiency of 19–22%. Actual energy generation depends on sunlight, tilt, temperature and shading.
- Electrical output: 400 W rated power with a ±5% tolerance; maximum power point voltage of 37.4 V and current of 10.6 A.
- Connection: MC4 connectors with MC4–XT60 and MC4–DC cables included.
- Surface protection: ETFE lamination and an IP67 protection rating.
Compatibility and use conditions
The supplied cables support connection to compatible ALLPOWERS S1500, S2000, S2000 Pro and R4000 power stations. For other brands, check the permitted voltage, current and solar input type before connecting.
The panel can stand beside a motorhome or be temporarily mounted on a vehicle while parked. It must not be used or left in that position while driving. The IP67 rating is not a recommendation to operate the panel in heavy rain.
