C&I Distributed PV Safety Solution
Factory, campus and logistics rooftops share a profile: large area, dense strings, frequent servicing and complicated ownership. A safety proposal has to answer more than "can it shut down" — it must answer what the retrofit costs, how long to commissioning, and who maintains it afterwards.
The four questions owners actually ask
These rarely get asked in a technical seminar, yet each one decides whether the project is signed.
From the business side
- Do we have to take an outage? A single lost production day can cost more than the equipment
- How many holes get drilled? Every penetration in a metal roof is a future leak
- Does the module warranty survive? Touching string wiring invites disputes
- Who maintains it? Every extra brand is another ledger the O&M crew won't accept
Our answers
- No outage: the device opens before work starts; other strings keep generating
- No drilling: clamped or screwed to the module frame, roof membrane untouched
- No topology change: string wiring stays as designed, module warranty intact
- One entry point: open interfaces to existing O&M systems, no forced replacement
Three layers, deployed block by block
A megawatt rooftop is rarely one plane — it is several buildings joined together. The design networks each block separately, so a fault in one does not take down the rest.
