My inverter and charger are separate so it's not making sense why batteries are not charging when inverter is off. I don't remember this being the case before.

no charging when inverter is OFF
We need a lot more information about your system and your components to help you.
Right now I'm looking for possibilities based on a typical system. I don't want to go too deep on specifics yet...just some common root causes that apply to most systems. Thanks
Are these victron systems? If so, what models. How are they connected? What battery? What bms? It is relevant. No one can help you with such vague information. As per the site terms, please detail your installation.
Victron Smartsolar MPPT charger, Giandel inverter and Amperetime Lithium batteries. Charger and inverter are both connected to battery bank thru master fuse. 1400W, 24V system (12V batteries connected in 2s2p arrangement).
I just re-read the last sentence.
You have only one fuse for the Charger and Inverter together?
This sound like the fuse is blown.
Please use SEPERATED fuses for the MPPT and Inverter.
Are your batteries fully charged? When your charger is OFF, what is the voltage of the battery pack? Are you sure the MPPT is actually charging the battery bank, or is it just offsetting the amps used by the inverter / load? Did any settings in the MPPT change? Could the BMS in the battery, block charging current. Any way to reset?
Change you charge the batteries with a standard charger?
The batteries had been drained (22V) triggering the inverter alarm and shutting it down. This has happened before and seems typical. After removing all loads and turning inverter back on the batteries began charging. When I turned inverter off the charging stopped. This is not typical. I don't see how the inverter can affect charging like that. Thanks
Since the MPPT need 5V more then the battery Voltage to startup, maybe your panels do not deliver enough voltage (hence at least 27V) while starting the Inverter it pull down the voltage deeper and the battery start charging.
However, your question lake of info's, e.G. which kind of Batteries, which Solarpanels, in series or parallel?
