Does EP800 has grid-assist function?

EP800 has 7600W AC OUTPUT (BACKUP). What if the load exceed 7600W? For example, if the load is 9000W. Will the EP800 be able to draw extra 1400W from grid to support the total load (9000W)?

@speeder2005
If maximun load not more than 110% (8360 watt) then it will run approx 10minitus. For 9000W load it will show over power alarm and cut off backup.
But its grid-tied, like when you use backup mode, 7600 watt use for backup load and rest use for charging EP800.

thanks! So to power 9000w load, I may need to add one more ep800 to run in parallel, right?
