No Inverter Charging After Solar
2016 Bounder with factory Magnum 2000W inverter/charger. I added a couple solar panels and Victron 75/15 MPPT charge controller. Charge controller was wired directly to the batteries (4x 6V in series/parallel).
Without the solar panels connected, the battery charger will not charge using the generator. No settings have been changed on the charger side and using the Victron app the charger was turned off/on with no difference.
I understood this would be an issue when the solar panels were plugged in, but why won’t the inverter/charger work as-is?

I believe that's referred to as "Operator Error". 
Glad you figured it out!

As for your comment about expected a problem when the onboard magnum when the solar is active, why is that?
My Midnight Solar Classic 150 and the onboard charger are ok together.

My understanding is that the solar charge controller won’t begin charging until battery voltage is below 13.1V (Victron specs). If the generator/charger is charging the batteries it will typically be above 14, so is the solar charge controller actually doing anything at this point?
Inversely, if solar brings the battery voltage above the trip point for the onboard charger, I would expect it to not begin charging until the batteries are below this voltage “trip point”.
This second scenario will probably never happen to me...I currently have 200W solar and a residential fridge. It’s mainly just to reduce generator run time.

Anything under 12.7 volts will get a good charger, whether 120 volt or solar powered, to supply voltage to the batteries.
They maintance 13.2 volts in float mode to keep the batteries up.
In cloud cover or night time, the charger will handle it, otherwise the solar will.

I know that symptom of a problem well - yep, self inflicted problems are my speciality  !
Another good test to see how power is flowing, is to lick you fingers and stick them into an outlet. You then get to be Tim The Tool Man (Shake it off!), Link from Mod Squad (Curls your hair!), and it's a preventative measure to keep the plaque from building up...
GLAD IT WAS THE MAN BEHIND THE CURTAIN, non problem !

Adding solar
I’m not sure I totally understand all the benefits but I am planning on adding solar panels on my 43’ American Revolution. Can anybody out there give me the basics in a nutshell? How many panels will I need? I understand they will keep my batteries charged when not hooked up to shore power or the generator is on.
