"Here - Hold my Beer"
Hi fellow DIYSOLARFORUM fanatic's and hopefully @MPP Solar USA - Ian Roux and maybe @Will Prowse @Otisd85 AND @BentleyJ is reading this also (since they seem to have had the same issue)... (Ian below is really a cut and paste of what my boss SAM just sent you earlier in an email) ... ////
Hoping you can help. I am going to try to make the issue as simple as possible, but I'm going to ramble.
We have a LVX-6048.
The LVX6048 is hooked up to an array of solar panels and also a 12000W generator.
THE PROBLEM IS::: The generator ONLY charges the battery when the Inverter is turned off.
If the inverter is turned on and the generator is running - the MPP senses the power coming in from generator BUT DOES NOT CHARGE THE BATTERIES and the batteries are still draining.
The panels DO charge the battery when the Inverter is on.
I have read on diysolarforum something about needing to have the operator out in the middle of nowhere bridge L1 + L2 but the last thing we need to do is ruin this.
Do you have any advice ...???

OK - here comes the additional info - i am including all of the below that MPP Solar Taiwan asked for BUT honestly was no help. They kept asking us to plug and unplug stuff - waste of time ... BUT the below is just in case it answers a question for you that could help resolve this. Below are some field notes from my engineer on settings.
The zip file are screenshots one of the kids took last night at the site of the MPP screen

Here are my parameters. We are using a FLOODED battery 48V 2000Ah (2000) ....
WHEN WE TURN OFF THE INVERTER- THE GENERATOR STARTS CHARGING THE BATTERIES !!! WE NEED FOR THE INVERTER TO CHARGE THE BATTERIES FROM THE GENERATOR WHILE THE INVERTER IS ON. If the generator is charging the batteries NO power (120V) is working since inverter is off.
01 SBU
05 BLU
06 BYE
07 LTE
08 LTE
10 SNU
11 90A
13 90A
14 FLD
all the others we went with the default that the system had ....
We are using a generator not UTILITY POWER.
BUT we have setting #10 as SNU which means that when the generator kicks on it should automatically charge the battery along WITH the solar. Right now its dark in the Texas oilfields. Generator is running - Your screen shows that it sees the generator running. 120V going in - 120V going out. BUT it is NOT charging the battery. And the battery is currently being discharged at 20A.
IF WE TURN OFF THE INVERTER THEN THE GENERATOR WILL SHOW A SOLID LINE TO THE BATTERY AND THE BATTERY WILL START CHARGING ...
GENERATOR RUNNING - NOT CHARGING BATTERY - MPPSOLAR DOES SEE THAT ITS PRODUCING 120v BUT NOT CHARGING BATTERIES???
GENERATOR IS RUNNING - NOT CHARGING BATTERIES - 120v OUTPUT IS WORKING
GENERATOR IS CHARGING BATTERIES - INVERTER IS OFF - NO 120v COMING OUT ...
GENERATOR IS OFF - INVERTER IS ON - 120v WORKING
GENERATOR IS ON - INVERTER IS ON - 120v OUPUT WORKING
INVERTER OFF - NO 120V OUTPUT - BATTERIES IS CHARGING via generator
