OSRAM BATTERYcharge SOLAR 100W OHPS100 – portable solar power for 12V batteries
The OSRAM BATTERYcharge SOLAR 100W OHPS100 is a portable, foldable solar panel designed for charging and maintaining 12V leisure batteries. Delivering up to 100W of solar power, it provides a practical way to support an auxiliary battery when a campervan, caravan or RV is parked away from a mains electricity supply.
Key benefits
- Up to 100W solar output for charging and maintaining a 12V leisure battery.
- 12V/10A charge controller with overcharge protection.
- USB output for charging small electronic devices.
- Monocrystalline solar cells housed in a robust aluminium frame.
- IP65-rated construction designed for outdoor use.
- Works in overcast conditions and does not require direct sunlight to begin generating power.
Where is it designed to be used?
OSRAM specifies the OHPS100 for 12V leisure batteries in caravans, campervans and RVs as well as general outdoor use. It is particularly useful when a vehicle is parked off-grid and the auxiliary battery needs a solar charging or maintenance source.
The quoted 100W is the panel's maximum power rating. Actual available power will vary with sunlight and operating conditions.
Charge controller and USB output
The system incorporates a 12V/10A charge controller with overcharge protection. OSRAM separately specifies a maintenance current of up to 4.95A. The 10A controller rating should therefore not be presented as the panel's confirmed charging current.
A USB output is also provided for small devices. The current product datasheet does not specify the connector format or the electrical rating of that USB output.
Construction and outdoor use
The monocrystalline panels are mounted in an aluminium frame with a sturdy aluminium stand. The design is foldable for transport and storage, while the IP65 rating supports outdoor use in accordance with the manufacturer's intended application.
Typical applications
- campervans with a 12V leisure battery,
- caravans and motorhomes,
- RVs,
- off-grid camps and outdoor use,
- maintaining a 12V leisure battery while parked.

Package contents
OSRAM confirms a solar panel with charge controller, an approximately 5 m battery lead and battery connection clamps. The technical specification separately lists a 4.92 m power cable and a 1.0 m clamp cable.
Installation and compatibility
The plug-and-play design is intended to simplify setup. The current manufacturer documentation confirms use with 12V leisure batteries. Compatibility with 24V battery systems is not stated and should not be assumed.
Frequently asked questions
Does it work in overcast weather?
Yes. OSRAM states that the panel can generate power without direct sunlight, although actual output will vary with conditions.
Can it be used with a 24V battery?
The current manufacturer documentation specifies 12V leisure batteries only.
Does the 10A controller mean a constant 10A charging current?
No. 10A is the controller rating. OSRAM separately specifies a maintenance current of up to 4.95A.
Can it charge USB devices?
Yes. A USB output for small devices is included, although its detailed electrical specification is not stated in the current datasheet.
