Optimiser. Gateway.
SolarSync™.
Panel-level MPPT, rapid shutdown and monitoring. Data runs over the DC cable, so there is no Wi-Fi to fail on the roof.
One string. One gateway. Any certified inverter.
The gateway sits in series between the string and the inverter. Power flows through; data rides the DC cable.
Archai iOPT 800W
Fits behind each panel. Tracks the maximum power point, reports live data and drops output to 0 W on shutdown.
Every panel at its peak
Shade, soiling and mixed orientations no longer pull down the string.
Shutdown at the panel
Voltage drops at each module for safe maintenance and emergency access.
Wired data
Communicates over the existing DC cabling. Fewer dropouts, fewer callbacks.
Genuine Stäubli MC4. The premium-panel standard.
Every Archai optimiser ships with genuine Stäubli MC4 connectors (PV-KBT4 / PV-KST4), the connector family that premium module makers fit to their panels.
- MULTILAM contact: sprung copper lamellae hold contact resistance below 0.25 mΩ
- Rated 1100 V DC (IEC) / 1500 V DC (UL), 39 A on 4 mm² cable
- IP68 mated, IP2X finger-safe unmated, −40 to +85 °C
- Like-for-like only: certification under IEC 62852 covers a mated pair from one maker. Cross-mating voids it and is a leading cause of DC arc faults.
- Positive click-lock, opened only with the Stäubli tool

Archai GT Data Gateway
Sits in series between the string and the inverter. Reads optimiser data over PLC, sends it to SolarSync, and triggers rapid shutdown.
Fit optimisers
One per panel, MC4 in and out.
Wire the gateway in series
Last OUT+ to inverter PV+. First OUT− through the GT ring to PV−. Add a 90–264 V AC supply.
Self-test, then map in SolarSync
10-minute self-test from the GT button, then place each optimiser on the layout.
