About this item
  • Adaptor alows you to connect several solar panels in parallel (to common positive and common negative terminals)
  • Connected panels can then be run through the same solar charge controller
  • Features a 10A blocking diode, to prevent backflow of power from the battery back to the solar panel
  • Ideal for large solar arrays, or can also be used as a blocking diode for a single panel
  • Has a male T4-compatible connector and a female T4-compatible socket, to easily plug into the end of solar panel cables. Scroll down to Product Description for more information.
Product description

This T4-compatible adaptor with a 10A blocking diode allows you to connect several solar panels in parallel (to common positive and common negative terminals) and run them through a single solar charge controller. It eliminates the risk of back flow of power through solar panels, particularly when different sized solar panels are used in the same array, or when one or more solar panels are prone to shading. The adaptor can also be used for a single solar panel as a blocking diode, to ensure that no battery power is fed back through the solar panel at night time. Subject to the maximum current and voltage rating of the adaptor (1000V 10A DC), it can also be used in more complex solar arrays with multiple strings of solar panels connected in series, in parallel, to ensure that power only flows in one direction. The adaptor features a male T4-compatible connector and a female T4-compatible socket, so it can easily plug into the end of a solar panel cable with a compatible connector. The adaptor can be easily disassembled if a diode inside needs to be replaced, and quickly reassembled. It is also fully waterproof, and suitable for outdoor application. Please contact Photonic Universe if you have any questions about this product.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days โ€” so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
