Victron Smart Shunt

The transition from a Magnum 12V inverter to a Victron 24 really pushed pushed this along, but the remote management capability of Victron is far superior to the Magnum. The fact that I can now remotely monitor/configure the inverter is just awesome. All this other monitoring was a HUGE bonus.

 

And now?
AGS is your next assignment....

 

Funny...been talking to Orlando about that.

Already bought the controller, just trying to decide where to install components.. The 410 has the remote start panel in the cabin, generator engine gauges by the fuel selectors, need both sets of wires to meet up somewhere...

The unit I bought is supposed to have a remote start function (I want to be able to start from this panel or a remote switch at the helm), but not working as expected, and my Chinese reading comprehension is a little low...




And if I get that working, why not go to the next lever and add an Auto transfer switch to both mains? Would start up and switch to the genny output.

 

I thought you decided on a Victron Quattro?? That would solve all of the transfer issues, simply.
The Cerbo/Quattro can be configured to start the genset based upon battery SOC and availability of shorepower.
The only thing missing is to figure out a way to convert the relay status on the Cerbo to a sequence to start the generator. I planned a simple timer relay for start/stop of the Onan sequence.
Plus the Cerbo/Quattro can sense if the generator in fact started and is producing power and if not it will re-perform the sequence up to X times.

 

I opted for a multiplus at this time. The Quattro was 3X the price, and not sure that where I'll end up and the Multiplus 2x120 has a lot to offer as well.

 

Switched the charger to a lower voltage AGM setting. 13.6 - 13.7 on all 3 batteries seems a little bit more reasonable.



the .2 Amp draw on the starboard shunt is correct…the Cerbo is on that side and is pulling 4 watts. Pull the fuse and it goes to 0.

 

Interesting - AGM float voltage should be 13.0 to 13.8 depending on temperatures.
Your LIFePo4 batteries should have a bulk/absorption charge at 14.0 to 14.6 and not really have a float. The confuser is when there are simultaneous discharges from the boat demands. At least that is how I understand it.
I would be cautious having an AGM charge profile on your lithium batteries; first that it is too low of a voltage to properly equalize (maybe the BMS will take care of this) and secondly to ensure the charger doesn't go into a desulftation mode.
Just my thoughts...

 

These are the AGM start banks (2x Group 31 AGMs plus the generator start battery) connected to the ProNautic 1240P. The Lithium batteries and inverter are not installed yet.

I switched to AGM Preset 1 vs AGM Preset 2 and per the table above, I think this works a whole lot better. Still actual voltage is about .1V - .15V higher on the Victron Smart Shunts than what shows on the charger display itself.

 

Ah - understand.
