Solar panel Allpowers SP037 400W portable

ALLPOWERS SP037 400 W Portable Solar Panel

The ALLPOWERS SP037 is a foldable solar panel rated at 400 W with a power tolerance of ±5%. It is designed to charge portable power stations when camping, travelling in a motorhome, staying at a holiday cottage or in locations without access to the electrical grid. The panel uses polycrystalline silicon cells, with a declared conversion efficiency of 19–22% and an open-circuit voltage of 45.3 V.

Foldable design for easy transport

The panel consists of five interconnected segments that fold down for convenient transport in a car or motorhome. An integrated handle makes it easier to carry, while adjustable supports help position the panel at an angle suited to the available sunlight. It is suitable for use while camping, at a holiday cottage, in a garden or during an extended stay off-grid.

400 W rated power and up to 22% efficiency

The 400 W rated output makes the SP037 suitable for charging higher-capacity power stations. Voltage at the maximum power point is 37.4 V, and current at the maximum power point is 10.6 A. The declared cell efficiency is 19–22%. Actual energy generation depends on factors including sunlight, panel angle, temperature and shading.

MC4 connectors and connection options

The ALLPOWERS SP037 uses MC4 connectors rated for currents of up to 25 A. This is the rating of the connectors; the panel’s short-circuit current is up to 11.45 A. The included cables allow connection to compatible ALLPOWERS power stations, including the S1500, S2000, S2000 Pro and R4000. Before connecting devices from other brands, check their required voltage, current and solar input type.

ETFE surface and IP67 protection

An ETFE laminate protects the panel surface during outdoor use. The IP67 rating indicates full protection against dust and resistance to brief immersion in water under specified test conditions. It does not mean the panel is recommended for operation in heavy rain.

For motorhomes, camping and off-road use

The panel can be placed beside a motorhome or temporarily mounted on a parked vehicle to make use of the available space while charging a power station. It is not intended to be used or left mounted while driving. After charging, fold the panel for transport.
