PARALLEL OF MULTIPLE MPPT'S WITH ESS ASSISTANT

GOOD DAY

HERE IS MY SETUP

MULTIPLUS2 5KVA

250/100 MPPT

250/60 MPPT

CCGX

SMART METER

240AHR GEL AGM BATTERY( ONLY FOR GRID FAILURE)


I HAD ONLY ONE MPPT(250/100) AND MY PEAK WAS ABOUT 3.6KW OF SUN DURING THE DAY, AND I ADDED THE 250/60MPPT YESTERDAY.

WITH THE BLUETOOTH APP I MADE ALL THE BATTERY VOLTAGES THE SAME IN BOTH MPPT'S

AFTER THE FIRST DAY THE SMALLER MPPT MADE 9.5KW OF SOLAR YIELD AND THE 250/100 MADE ONLY 6.5KW SOLAR YIELD.

MY CONCERN IS THAT THE SMALLER MPPT IS WORKING HARDER AND I TRULY KNOW IT CAN HANDLE ITS JOB. I JUST WANT TO KNOW IF THERE IS A SETTING THAT I MIGHT HAVE MISSED WHEN CONNECTING MULTIPLE MPPTS IN PARALLEL?
