Giv ac 3.0 led flashing green

The led on our inverter is flashing green following a power cut, during which we mistakenly switched the inverter off. The dongle is showing blue and the software is working. However the batteries are not charging. Suggestions most welcome?

Flashing green means ‘waiting’ either for excess generation in order to charge and/or there is no energy remaining in the battery to discharge. This has probably happened every day since it was installed but you’ve never seen it before.

Thanks DMGN. On more general matter: is there a manual that explains the various LED signals and how to manage issues that they indicate?
