IDEA...charging house battery(set) underway.
It seems that the chassis alternator/VR system will often not fully charge the house battery(set) due to voltage drop between the two, or overcharge, boil the electrolyte away, for a deeply discharged...

Bumping, because I am still wondering what to buy :).
Will a good isolator, e.g. Sure Power also regulate the voltage to my house batteries, and change it according to their SOC? Or do I need to do something more?
An isolator does not regulate battery voltage, but rather will isolate the main and house batteries during discharge.
The vehicle alternator is regulated and it provides adequate charging for the main battery while the engine is running.
If the house battery is stored some distance away, and they are not getting charged while driving, the culprit is probably undersized charge cables.
The convertor will charge the batteries while connected to shore power.
