I would anticipate you would have to run the generator a bit in the evening and morning, depending on previous days sun and power usage. The nice thing with a AIO is it would run the cabin from the generator power while charging the battery until solar kicked in.
This model supports much more solar, but is not as plug and play. You could wire it with extension cord ends like Will does for demos, make your own MC4 connections for PV and use Anderson connectors for the battery. All easy to do, just time and a bunch of little components to gather.
Price wise, this seems to be the going rate. MPP and Growatt have comparable models in the 24v range. MPP and EG4 are the seem to be the go to for 48v systems.
im comparing magnum to the mpp. Magnum is 3x the cost, and it doesn’t have a charge controller. What’s magnum got to justify higher price? What does mpp not have? Usually you get what you pay for.
but I really like these new all in ones. It’s been a few years since I was “into” solar. Things have changed.
