I have growatt SPF 12000T DVM-MPV connected to 3 phase old diesel generator 80kw 250amp(we connected 2 phases). I set all applicable settings to at least 80amps but growatt still showing 30am ac input.

We have 3 felicity solar 10kwh batteries in parallel which can take 120amp charging. What am i doing wrong.
 
You are not confusing AC and DC amperage? AC voltage means different amps for the same wattage.

I dont think so. Reading the ac input off the inverter

I don’t think the issue is the batteries. It cant be coincidence that the growat default ac input is 30amps and that is what it is showing . Somehow the changes we made on the settings are not being executed.

You are confused between AC input Amp into the charger and DC output Amp being drawn by the batteries, those two Amp are not interchangeable.
 
Thank you for your replies. My main concern is ac input is only showing 30amps which is the default setting when the generator is capable of much more. I will need find how much amp is going into the battery and use the conversion factor. I did speak with signaturesolar and I may need to completely turn off the growatt for settings to change to 80amps max.
 
Reading through the manual I do see a setting (#11) called maximum utility charging current that gives 30a as default. Note this is DC charging current and not AC input power. You would want to raise this by pressing the up button until your reach the amount of DC charging current you want. Than you must press enter to set it. Your setting (#2) for the maximum charge current from both utility and PV has to be set first higher than what you set the max utility charge current at. Its default is 80a. I would up this to what you expect PV and utility to max out at. Be careful not to exceed maximum battery charging current.

Yeah i set both of those higher. I think it just needs to be reset for those changes to actually take affect. This is in a remote location so once I go back, I will try disconnect reconnecting power and see if it fixes it. I report back.
