Order of Work
Confirm the site
Verify the site against Choosing the Location and the G3 limits: altitude ≤ 4000 m, adequate clearances, and correct airflow path.
Mount the unit
Follow Kent G3 Mounting — wall load-bearing, clearances, and the ±5° verticality rule.
Earth it
Complete Kent G3 Earthing before any PV, battery, or AC wiring.
Wire in order
PV wiring → Battery wiring → AC wiring → CT & Meter → Comms & Parallel → GEN & Smart Port if used.
Commission and check
Run Kent G3 Commissioning, then complete the G3 Commissioning Checklist.

Which metering kit you have matters. The CT scheme ships a 100 A/50 mA CT set. The meter scheme ships the three-phase meter plus 120 A/40 mA CTs. More than three units in parallel requires a separate 300 A/5 A kit. Check the kit against the order before leaving the warehouse — ratios and wiring details are on CT & Meter. [KNB-VAL-08]
Handling
Two people are required to lift and hang this unit. Use the carton cutouts and the heat-sink handles. Lower the unit slowly onto the mounting bracket — the G3 weighs up to 42 kg.Wiring Overview
Conductor sizes and OCPD ratings are determined by local electrical standards on top of the platform figures given on each wiring page. The backup loads panel must not be electrically connected to the main service panel at any point — not even temporarily during testing.Common Mistakes
- Leaving the warehouse with the wrong metering kit for the order type — only verifiable at the site.
- One-person lift on a 42 kg wall unit.
- Tying the backup subpanel to the main panel “temporarily” and never removing the bridge.
