A compact field checklist for polarity, torque, cable entry, fuse failures and SPD status.
1. Installation checks
Verify string polarity, conductor preparation, terminal torque, gland sealing, protective earthing, fuse compatibility and circuit labels before energization.
2. When a fuse keeps opening
Do not simply install a larger fuse. Check reverse-current exposure, string faults, wiring damage, fuse class, temperature conditions and coordination with the module maximum series fuse rating.
3. Request project guidance
Send the string data, single-line diagram, installation environment and target market to sales@vioxsolar.com for a project-specific discussion.
