Malaysia’s National Energy Transition Roadmap (NETR) sets a net-zero 2050 target and a phased build-out of rooftop and utility-scale solar under the Large Scale Solar programmes. As module-level rapid shutdown shifts from good practice to procurement expectation, Hisolarmate offers a cable-free, standards-aligned solution already proven in tropical conditions.
Malaysia’s solar pipeline is growing through the LSS programme and a fast-expanding commercial and industrial rooftop market, with data-centre and industrial-estate demand adding further pressure on grid capacity. In that environment, how a rooftop array behaves during a fire or emergency isolation stops being a technical footnote and becomes a procurement question.
The National Energy Transition Roadmap sets a phased renewable build-out towards net-zero 2050. Module-level isolation supports the safety case for that growth.
Large Scale Solar programmes bring utility-grade procurement discipline to safety requirements — including how faults are isolated at array level.
Factories, logistics parks and industrial estates are adding rooftop PV at pace. Cable-free retrofit matters where existing structures cannot take new trunking.
Where fire services must enter a roof area, being able to bring array voltage down quickly and verifiably is the difference between a safe intervention and a standoff.
Safety case support for distributed and utility-scale solar, with third-party-verified operating data available for qualification review.
Module-level isolation across multi-roof and multi-inverter sites, with expansion capacity designed in from the start.
Retrofit without shutdown or new cabling, plus remote monitoring that reduces the need for on-site inspection.
MC4 plug-in installation, roughly half the wiring terminations, and documentation packages suitable for handover.
Figures below are our tested and delivered values. Competitor references are drawn from public sources and third-party test reports and are provided for objective comparison only.
| Reference | Requirement | How we meet it |
|---|---|---|
| NEC 690.12 | Array boundary down to 80V within 30s | Down to ≤1V within 25s — a margin of 79V over the limit |
| IEC 62109 / IEC 62548 | PV power conversion and array design safety | CE and IEC 62109 referenced product design; array-level isolation architecture |
| MS IEC series | Malaysian adoption of IEC PV standards | Design basis aligned with IEC; documentation available for local review |
| Fire-service coordination | Emergency isolation and fire-brigade interface | Gateway emergency-stop button plus dry-contact interface for fire-system integration |
| PDPA 2010 | Personal data protection | The safety system processes equipment telemetry, not personal data; deployment options discussed per project |
Our closest regional reference sits in the same climate band as Malaysia: a factory rooftop in Southeast Asia, running unattended under sustained heat and humidity.
LDSW Smart Shutdown Device, Smart Network Controller and PV Safety Cloud Platform — wireless, cable-free and retrofittable without shutdown.
For BESS deployments: oxygen displacement, deep cooling and explosion control act together to interrupt thermal runaway before deflagration.
For project evaluation, sample testing and commercial discussion in Malaysia and the wider ASEAN region.
