Argofet Battery Isolator Multiple Inputs

I have a two LionEnergy UT1300 lithium batteries being used as two separate house batteries on a sailboat. I’m using a Victron Orion TR Smart 30 amp DC to Dc charger to charge both batteries independently through a Victron 200 amp 2 output Argofet battery isolator when the engine is running. I also have a Victron MPPT 30 solar controller charging the batteries when the boat is on its mooring and the engine is off. The solar panels are 2 x 100 watt but looking to upgrade as they’re not producing anywhere near 100 watts. Lastly I have a Victron Blue Smart 15 amp 110/12 volt charger I use when shore power is available.

Is it ok or correct to connect multiple source power inputs into the Argofet Battery isolator? All three (Dc to DC, solar, and 110/12) wouldn’t be supplying power at the same time, at most it would be the DC to DC charger and shore power 110/12 volt or Dc to DC charger and Solar. All sources combined would be 75 amps maximum, well under the 200 amp rating of the Argofet battery isolator.

Thank you for your advice.

All the Argofet does is isolate the batteries and allow charge to both. There is no difference when comparing all 3 devices connected directly to a single battery the battery will charge. You may be able to tweak the settings like having the DC-DC go into absorption early and use the solar charger for example. I have done this I have both solar and DC-DC on my boat and set the DC-DC to absorption at 13.6V and the solar will go to 14.4V.

Just monitor and see what the system does and tweak if its not doing what you like.

Thank you very much for the quick response.

I will try adjusting the settings and see how they affect the system.

Thanks again!
