Quattro: Set charge current depending on AC-IN ?

Am I the only one to miss this feature?


Quattro 5kVA, AC-IN1: Generator AC-IN2: Grid

I would like to set the max. charge current for the generator somewhere below its nominal capacity (somewhat around 8A), I would like to keep the charge current setting for grid as is - which is 1A.

In other words: When connected to grid, charge the battery as little as possible, when connected to generator, charge with generator capacity.

VEConfigure: No dice. Only one global galactic value can be set here for the charger.

Any ideas how to achieve that feature or shall I include that in my Victron prayers?

Take a look at the charge current control assistent.

That looks like it could do the job, although I need it for quite the inverse use case than is described (less charge for grid, more for generator), but that will probably not matter.

So if the Genset can deliver - say - 1800VA continuous and is rated 7.8A, I would limit AC-IN1 to say 7.5A and set the charge current limit (because it is in DC Amps and a 48V system) to ... 30A, right?

To limit the current on the AC input you could just use the input current limit at the 'grid' tab.
