The SigenMicro AC Branch Unlock Tool is a small handheld tool designed to safely disconnect a SigenMicro microinverter from the AC Trunk Cable on a rooftop solar array. The trunk connectors are deliberately locking and weatherproof, so a dedicated tool is needed to release the branch connection without damaging the cable or connector body.
It is used whenever a microinverter needs to be removed, replaced, or re-positioned — for example during fault diagnosis, servicing, or a PV module swap — allowing the installer to unclip the branch lead cleanly from the AC Trunk Cable and reconnect it, or a replacement unit, without disturbing the rest of the trunk run.
The tool is fork-shaped, sized specifically to the SigenMicro branch connector, and is part of the same accessory family as the AC Trunk Unlock Tool, which performs the equivalent job on the trunk couplers rather than the individual microinverter branch connections.

Please Note
This tool releases the connection between a SigenMicro inverter and the AC Trunk Cable specifically. It is a different tool to the SigenMicro AC Trunk Unlock Tool, which is used to open the AC Trunk Coupler for wiring — the two are not interchangeable.
Purpose-Built Fork Design
Shaped specifically to grip and release the SigenMicro branch connector without applying force to the surrounding cable jacket or trunk cable.
Safe Microinverter Removal
Lets installers disconnect a single SigenMicro unit from the AC Trunk Cable for replacement, relocation, or fault-finding, without cutting or damaging the cable.
No Damage to Locking Connectors
Designed to release the connector's locking mechanism cleanly, so the branch connector can be reconnected and remain fully weatherproof afterwards.
Compact Handheld Tool
Small enough to carry in a standard installer tool bag alongside the SigenMicro AC Trunk Unlock Tool for full rooftop connector servicing.
Part of the SigenMicro Accessory Range
Designed as a companion tool to the AC Trunk Cable, AC Trunk Coupler, AC Trunk Terminator and Port Cap, covering the full connector servicing kit for a SigenMicro installation.
No Ongoing Consumable Cost
A one-off tool purchase for the installer or maintenance team — not a per-use consumable item.

Important Safety Information
Disconnecting a live microinverter from the AC bus must only be carried out by a qualified electrical installer with the system safely isolated where required. Always follow the manufacturer's system wiring and safety guidance before working on rooftop connectors.
What does the SigenMicro AC Branch Unlock Tool actually do?
It releases the locking connector that joins a SigenMicro microinverter to the AC Trunk Cable, allowing that inverter to be disconnected for replacement or maintenance.
Is this the same as the AC Trunk Unlock Tool?
No. The AC Branch Unlock Tool disconnects an inverter from the trunk cable, while the AC Trunk Unlock Tool is used to open the AC Trunk Coupler for wiring two trunk sections together.
Can the connector be reused after being unlocked with this tool?
Yes, the tool is designed to release the connector without damaging it, so the branch connection can be reconnected and remain weatherproof.
Do I need this tool for a standard SigenMicro installation?
It is not required for initial installation, but it is a useful tool to have on hand for any future microinverter servicing, fault diagnosis, or replacement work.
Which SigenMicro models is this tool compatible with?
It works with the full SigenMicro range connected via the standard AC Trunk Cable system, including the 400, 500, 800 and 1000W models.
