Why is grid import capped at 10.5 kw

Q&A and troubleshooting

Following on from my previous post, I suspect this may be related to the AC input current limit.

My grid connection is single-phase, rated at 63A. While charging the battery overnight, I normally see grid import capped at around 10.5 kW, which corresponds to roughly 45–46A. On a few occasions—when the battery charger and my EV charger were running simultaneously—I’ve briefly seen imports of 14–15 kW, so I know the supply itself can deliver more.

This makes me think there may be:

  • An AC input current limit set in the Quattro

  • A GX system-wide limit overriding the inverter setting

  • Or a dynamic limit via ESS / DVCC that I’ve overlooked

Could someone advise:

  • Where the authoritative AC input current limit should be set (VE.Configure vs GX)?

  • Whether ESS or DVCC can silently cap grid import under normal conditions?

  • And which value would be appropriate for a 63A single-phase supply?

Any guidance would be very much appreciated.

Thanks again.
