Due to unavailablity of the bigger Quattro II in time, it looks like I'll end up using a Multiplus II 48/10000 for my boat build. This means having an external switch between generator and shoreline, so I'm looking for ideas about how to do this and how to change the AC current limit.
I could use a relay controlled by the Cerbo GX to do the switchover, if the MP II can be used to detect whether AC is present at the input or not, with an assistant to switch over -- for example, have the relay default to shoreline, then if there is demand for AC power (e.g. to charge batteries) and there is AC present use this, if not flip the relay over to the generator and start it, then reverse all this when AC demand is over (I won't always need an AC source, boat has solar panels fitted).
Is this possible, and if so has anybody tried it?
A second issue is how to change the AC current limit, the generator can supply 38A but the shoreline will typically be 16A -- but could also be 32A if the bollard allows this (not common on UK canals). Can the Cerbo GX change the MP II current limit depending on whether shoreline or generator is selected?
If none of this works then I'll have to fit a manual changeover switch, and manually change the AC current limit, either by just entering a new value (prone to error) or providing soft buttons to select the correct value -- again, can this be done by an assistant?
Yes a Quattro would be much easier, but for various reasons I don't want to use the old model... :-(
