HELP Error code 26 and 27

[ernie34]

hi


sorry to post this

I have just followed the guide to install an additional battery, all ok except for these two error codes?

26 = grid voltage fault

27 = grid frequency fault

as you can see from the photos the power is coming from the panels but not going anywhere else ?

I've looked it up and google says it will just balance and clear the errors?
is this correct ?


thank you in advance

All sorted system working as normal.

Just shut system down and rest it?
