Hello,
I am having a heck of a time trying to figure out a way to make two ET112s work together, and display information, in a split phase configuration. This is somewhat necessary as we have boats that have 2 separate 30amp 125v marine shore inlets.
I have found a basic workaround to at least have the total AC loads displayed by making one Grid and second one Generator, but they are not displayed together on the panel, only the total is used.
This is manageable, but I am a bit confused of why the Cerbo can't determine that the two ET112s are separate lines on the same system and enable split-phase configuration. It seems a very basic change in settings on the Cerbo side, which would enable a world of opportunity.
As a Marine Electrician and Electronics Installer, we run across a ton of people who would like an easy way to get the data about their vessel but not have to spend a ton of money right now. Installing a Cerbo is such an easy way to introduce them to the Victron product line and then slowly bring them into the fold with batteries, inverters, and other products. Sadly, cost is always an issue and most of my clients are gunshy on spending $20K on an entire electrical system overhaul. Getting the units like ET112 to work in split phase environment would give them the ability to see their shore power or generator load while also not having to spend a ton of money. Adding Smart Shunts would then allow for battery status and load management. This would get them used to the available information, and then when the time comes they will buy the Victron Inverter and LiFePO4 batteries that will easily fit into the system.
