I noticed today that one of my 3000EHV inverters has a pretty significant amount of error on battery current. It's constantly 10A higher than actual. Calibration on PV current isn't great either. My other 3000EHV is within 1A. Has anyone found a way to calibrate these?

Where are you seeing this information?
Are you getting any error codes on the inverter?
Are you getting any error codes on the inverter?
No error codes. I initially noticed the discrepancy in data provided by Solar Assistant. I then confirmed it on the inverter's LCD screen.

What are the exact readings it's giving you?

Are you BMS communicating with the master inverter, or do you have it set to lead acid? Also, how many batteries do you have?
I have two Lifepower 4 batteries. The inverters are set for user mode. Solar Assistant is gathering data from the BMSs.

It appears to be just reactive power in the lines, but we will conduct some tests to confirm. Currently, we are a bit short-staffed due to the holiday weekend, but we'll update you with the results as soon as we have them.
