Hi everyone 👋👋
another weird problem faced me in my career in solar systems
so this time the problem is little confusing i need your help guys
i have installed 2 5kw 48v felicity inverter
300 48v felicity lithium battery
16 jinko 585w solar panel

and connect each other on parallel as split phase as they say in the user manual
everything is working fine when the output from solar panels to the load , the load is balanced in the 2 inverters
i use the output priority to (SUB) so as i know that the loads is form solar panel as they have the enough wattage of load

but the problem when the grid is on (Note: i used grid just to bypass the load of home Not for charge ) the units have unbalnced on load so one inverter have load more than the other
pic one shows how much output load on each
pic:2 show how much solar panel is generate
i notice that the right side inverter is always have much load than the left one
so how can i fix that problem
