The GSE Micro-Inverter Fixing Screw is the dedicated fastener used to attach a micro-inverter or power optimiser directly to the mounting rail of a GSE On Roof or GSE Ground System frame, using the slotted fixing holes built into the rail.
GSE frames include slotted mounting holes specifically for this purpose, allowing micro-inverters and optimisers to be positioned and secured at the point in the array that suits the cable run, without additional brackets or drilling into the rail.

Please Note
Always check the micro-inverter or optimiser manufacturer's installation manual before fitting, to confirm mounting orientation, torque and any manufacturer-specific bracket requirements. GSE specifies compatibility with all micro-inverters and optimisers on the market via the rail's slotted fixing holes, but individual device manufacturers may have their own mounting recommendations.
Purpose-Built for GSE Rails
Sized and threaded to engage the slotted fixing holes on GSE On Roof and Ground System mounting rails.
Wide Device Compatibility
GSE's mounting rail is designed to be compatible with all micro-inverters and optimisers on the market.
Flexible Positioning
The slotted hole pattern allows the fixing point to be adjusted along the rail, so the inverter can sit close to the relevant module string.
No Extra Drilling
Uses the rail's existing slots, avoiding the need to drill through the frame to fit inverter mounting brackets.
Straightforward Access for Servicing
Because the screw fixes into an open slot rather than a blind hole, inverters can be repositioned or removed for servicing without damaging the rail.
Suits Roof and Ground Installations
Used on both the GSE On Roof rail system and the GSE Ground System, wherever the slotted rail profile is present.

What is this screw used for?
It fixes a micro-inverter or power optimiser to the slotted mounting rail of a GSE On Roof or GSE Ground System installation.
Will this fit any micro-inverter brand?
The GSE rail's slotted fixing holes are designed to be compatible with micro-inverters and optimisers from any manufacturer. Always check the inverter's own installation manual for mounting specifics.
Do I need to drill the rail to fit an inverter?
No. The screw engages the pre-formed slotted holes already present in the GSE rail, so no additional drilling is required.
Can the inverter position be adjusted after installation?
Yes. Because the fixing uses a slotted channel rather than a single fixed hole, the inverter can be slid along the rail and repositioned as needed.
Is this the same fixing used on the GSE Ground System?
Yes, the GSE Ground System rail uses the same slotted fixing principle for mounting micro-inverters and optimisers.
