- 4mm Solar Connector Disconnect Tool
Get to Know Your Gear
The panel features a junction box, 4mm solar connectors (compatible with MC4), and metal eyelets at each corner for mounting. The panel is flexible, with a minimum bend radius of 0.4 meters in the lengthwise direction.
Installation and Usage
The Flex 100i includes four mounting holes, one in each corner, for installation in your desired configuration. The panel must be secured or fastened to a stable surface to ensure efficiency and prevent damage over its lifetime. If you have concerns about installation, consult a professional.
Disconnecting Panels: The included 4mm Solar Connector Disconnect Tool is required to safely disconnect the solar connectors. Push the prongs of the tool onto the connector tabs to release the connection.
Connecting Multiple Panels
When connecting multiple panels, you must consider the voltage input limitations of the device you are charging. The total input is affected by whether you use a series or parallel configuration. Consult the Goal Zero website for information on the optimal setup for your specific device.
