question

Thanks for your help Rob. I can see at 4.3.9 in the manual here: https://www.victronenergy.com/live/ess:design-installation-manual#gx_device_-_ess_settings

It states:

4.3.9 Limit charge power

This setting limits the amount of AC power used by the Multi for battery charging. The limit also applies to AC power received by the Multi from a grid-tie PV Inverter.

In other words, this setting limits the flow of power from AC to DC.

• This setting does not reduce the charge power coming from MPPT Solar Chargers.

• This setting only applies to utilities connected to AC-in: In inverter mode, the 'charge-current setting' - as configured in VEConfigure - is used to control power coming from grid-tie PV Inverters.

There appears to be some potential contradiction here in terms

1. "The limit also applies to AC power received by the Multi from a grid-tie PV Inverter"

2. "This setting only applies to utilities connected to AC-in"

Apologies if this is a stupid question but I just want to double check I understand this, especially the last point. Assume that the 'charge-current-setting' is set to 0. Does this mean that per my diagram above: if I have a grid tied PV inverter connected to loads on the the AC-out, that any excess power which isn't used by loads on the AC-out will be used to charge the batteries but no power will be drawn from the grid via AC-in to charge the batteries?
