Sigenergy Sigen Gateway HomePro Three Phase

• Manufacturer Sigenergy

The Sigenergy Sigen Gateway HomePro Three Phase is the high-speed transfer switch and power-distribution hub that unlocks true whole-house backup for Sigen PV-battery systems. Sitting between the grid, Sigen inverters, HV batteries, rooftop PV and an optional diesel generator, the gateway performs seamless 0 ms switching, advanced load-prioritisation and anti-back-feed protection—features that commercial-grade installers now expect on premium residential projects.

Core performance

Instant continuity – solid-state relays deliver 0 ms load-side disruption when the grid fails, so heat pumps, servers and security circuits remain online.

High-power architecture – handles 30 kW, 380/400 V 3-phase at 45.6 A per phase for both grid and backup ports, matching today’s larger inverters and EV chargers.

Integrated bypass circuit – a mechanical bypass ensures continued power flow during service or firmware updates, increasing system availability.

Smart port for generators – supports two-wire auto-start and full monitoring, letting clients top-up batteries during long outages.

Rapid export protection – real-time current sensing with 350 ms anti-back-flow response fulfils DNO zero-export mandates.

Installer-focused advantages

Drop-in commissioning – DIN-rail gland plate, rear cable entry and auto-addressing with Sigen Controller cut install time to under an hour.

Multi-source flexibility – orchestrates PV, ESS, grid, generator and V2X simultaneously, allowing future EV-to-home upgrades without extra switchgear.

Load priority engine – define essential vs. non-essential circuits; the Sigenergy Sigen Gateway HomePro Three Phase sheds non-critical loads to extend battery run-time automatically.

Code compliance built-in – over-current, over-voltage, islanding and surge protection are pre-certified to EN & IEC standards, streamlining DNO approvals.

Remote firmware & diagnostics – via Ethernet, installers can push updates, read fault logs and adjust load settings without a site visit—reducing O&M costs.

Ideal applications

Premium homes or small businesses needing uninterrupted three-phase backup up to 30 kW.

Sites with on-site gensets where automatic, smart control is mandatory.

Projects planning future V2X or additional Sigen battery stacks—scalability is native.

By integrating the Sigenergy Sigen Gateway HomePro Three Phase, installers deliver a single, intelligent switchboard that protects revenue, simplifies call-outs and gives end-users bullet-proof energy resilience.
