I bought the Magnum which is a hybrid. That means it is similar to a grid tie inverter for a solar application, although it's not a solar controller. I bought the extra modules for it to be able to start the generator automatically if the temp inside either the Airstream or the Sprinter gets above a set point or the battery charge falls below a certain percent. Magnum has real engineers that you can talk to if you get their contact info on-line
Actually, Magnum's hybrid inverters bear almost no resemblance to grid-tie models.
What the MSH series of inverters provides is 'load support' that allows you to access the power reserve in your battery bank to supplement any insufficient grid or generator source to start and run say...... a roof A/C from a single 2000 watt generator or 15 amp shore cord.
The MSH will seamlessly provide the additional amperage to start the A/C unit and will back off it's assist after the compressor starting surge is complete, allowing the 2000 watt genny to 'operate' the running loads of the A/C alone. The cycle repeats as needed.
The biggest issue to remember is the type of batteries you are using and the size of that bank. Lead batteries are subject to Peukert effect which effectively diminishes the practical, usable size of any lead battery bank by an exponential factor that is dependent on both the size of the load and size and type of battery used.
Lithiums show no effect from Peukert losses.
