is there a diagram or unit that will allow me to take a cord directly from the wall plug and power from solar panels to combine the two? i’m needing about 900 watts combined between the two. only unit i’ve seen thus far can only do 250 watts

WOW!!! DANGEROUS!!!!!!

NO! you need to first take the DC voltage from the solar panels and convert it to AC

Next you need the AC from the solar panels to be sine wave (NOT A MODIFIED SINE) and then you need to sync the output from the solar panels to the grid.

This requires a control panel.

It would be far simpler to have an automatic change over from your solar panel (battery bank, power inverter) to change over when the grid falls.
