Inverter Off Line

Help - Both my App and Web are showing the Inverter as being "off-line" I have an AIO and Gateway which was commissioned on Friday and everything has been OK. What steps do I need to take to get the inverter back on line?

I have this issue a lot, since I started keeping track ive had to manually shut down and power up the AIO on
October 10th, 16th, 27th
November 8th, 15th, 17th, 20th, 21st (today)

Looks like its going to be a daily affair now.

The system will operate as it should you just wont be able to access the portal or any settings so if you don't keep changing things you could wait and hope it comes on by itself.

EDIT
Looks like its gone off completely now as im drawing from grid as well, good bloody god.

Jellybaby Thank you. My Electrician is back tomorrow so Ill ask him how to do this. Have GivEnergy given you any advise?

KCowling I have been pressing the power button on side of aio (hold for a few seconds in then let go) and wait for it to click then flipping the breaker switch next to it in the casing down then powering the AIO off in the gateway til the light goes out on the AIO then flipping the power back on in the gateway, pushing the breaker up on the AIO unit I flipped down and waiting, can take a few minutes for inverter to kick back online (you will be running off battery before that sooner) but id wait for sparkie so he can show you himself so you can see visually what to do.

I don't think its a cable connection issue as I had this problem when I was on wifi as well as connected via LAN, something has to be going on with the units or their software and its increased from every 1-2 weeks to 2+ times a week since going on beta firmware.
