Product Information

Full details

The OSRAM OSP500 is a solar-operated battery maintenance device designed for 12V vehicles, ideal for owners of seasonally used vehicles like caravans, classic cars, and motorcycles. Its key benefit is maintaining optimal battery charge using free solar power, preventing battery discharge from constant electrical system consumption. A potential caveat is that its performance is best in direct sunlight, though it can still function in sufficient daylight.

Extended Product Information

FAQs

What type of batteries can the OSP500 maintain?

The OSP500 is designed for all 12V lead-acid and VRLA vehicle batteries.

Can this device charge a completely dead battery?

The OSP500 is a battery maintenance device, not a rapid charger. It is designed to maintain the charge of a healthy battery and prevent it from discharging further. It cannot revive a deeply discharged battery.

How do I know if it's working?

While there isn't a specific indicator light for charging, you can observe the battery voltage over time or rely on the fact that it's actively offsetting the vehicle's continuous power draw. Ensure the solar panel is clean and receiving light.

Is the OSP500 waterproof?

Yes, the OSP500 has an IP65 waterproof rating, making it suitable for use in various weather conditions.

What is the cable length provided?

The OSP500 is supplied with a 3-meter (approximately 9.8 feet) length cable.

Can I use this for my motorcycle battery?

Yes, the OSP500 is ideal for maintaining 12V motorcycle batteries, especially during periods of non-use.

Does it require any special installation?

No, installation is simple. You can either plug it into a 12V DC power outlet or connect it directly to the battery terminals using the included clips.

Troubleshooting

Device not maintaining battery charge

Ensure the solar panel is clean and exposed to direct sunlight or sufficient daylight. Check all cable connections for security and corrosion. Verify the vehicle's 12V battery is healthy and not deeply discharged.

Battery clips connected incorrectly

The OSP500 has polarity reversal protection. Disconnect the clips, ensure the red clip is on the positive (+) terminal and the black clip is on the negative (-) terminal, and reconnect.

Reduced charging performance on cloudy days

This is normal. Performance is best in direct sunlight. While it operates in overcast conditions, the output will be lower. Ensure the panel is clean for maximum efficiency in available light.

12V DC plug not providing power

Check if the vehicle's 12V accessory socket is functional by testing it with another device. Ensure the socket is active (some are only powered when the ignition is on).

Pros and Cons

Setup, Compatibility & Care

Setup:

  1. Placement: Position the solar panel in an area that receives maximum sunlight. For vehicles, this could be on the dashboard or exterior.
  2. Connection: Choose one of the provided connection methods:
  • 12V DC Power Plug: Insert the plug into your vehicle's cigarette lighter or 12V accessory socket.
  • Battery Clips: Connect the red clip to the positive (+) terminal of your 12V battery and the black clip to the negative (-) terminal.
  1. Polarity Protection: The device has built-in protection against incorrect connections. Ensure connections are secure.

Compatibility:

  • Designed for all 12V lead-acid and VRLA vehicle batteries.
  • Suitable for cars, motorcycles, caravans, RVs, boats, and other vehicles with a 12V battery system.

Care:

  • Solar Panel: Keep the surface of the solar panel clean. Wipe with a soft, damp cloth periodically to remove dust, dirt, or grime that can reduce efficiency.
  • Connections: Ensure the battery clips and DC plug remain clean and free of corrosion.
  • Storage: Store the unit in a dry place when not in use for extended periods, though it is designed for outdoor weather resistance.
