Allpowers SP037 400W Portable Solar Panel
The ALLPOWERS SP037 is a foldable solar panel with a rated power of 400 W and a tolerance of ±5%, designed for charging portable power stations while camping, traveling in a RV, staying at a summer cottage, or in locations without access to the electrical grid. The panel uses polycrystalline silicon cells, and the declared conversion efficiency is 19–22%. The open-circuit voltage is 45.3 V.
Foldable design for easy transport
The panel consists of five interconnected segments, allowing you to reduce its size after use and transport it more conveniently in a car or RV. An integrated handle makes it easy to carry, and adjustable legs allow you to position the panel at the optimal angle relative to the sun. This solution works well whether you’re camping, at a summer cottage, in the garden, or during an extended stay off the power grid.
Rated power of 400 W and efficiency up to 22%
The rated power of 400 W allows the SP037 to be used to charge power stations with higher capacity. The voltage at maximum power point is 37.4 V, and the current is 10.6 A. The declared cell efficiency ranges from 19% to 22%, though the actual amount of energy generated depends, among other factors, on sunlight exposure, the panel’s angle of inclination, temperature, and the degree of shading.
MC4 Connectors and Extensive Connection Options
The ALLPOWERS SP037 uses MC4 connectors with a rated current of up to 25 A. This is a parameter of the connector itself—the panel achieves a short-circuit current of up to 11.45 A. The included cables allow the panel to be connected to compatible ALLPOWERS power stations, such as the S1500, S2000, S2000 Pro, or R4000. For devices from other brands, check the required voltage, current, and solar input type before connecting.
ETFE Surface and IP67 Rating
The panel’s surface is protected by an ETFE laminate, which safeguards the cells during outdoor use. The design is rated IP67, meaning it provides full protection against dust and resistance to brief immersion in water under specific test conditions. However, this rating should not be interpreted as a recommendation to operate the panel during heavy rainfall.
For RVs, camping, and off-road use
The panel can be placed next to the RV or temporarily mounted on the vehicle while parked, allowing you to use the available space to charge the power station. It is not intended for use or to be left in this position while driving. Once charging is complete, it can be folded up again and prepared for further transport.
