Hi,
I’ve been following this thread because my unit has been working great for almost four years and now has suddenly start displaying the same issues as the OP.
I’ll try and attach a video of it throwing a wobbly when the sun comes out. Unfortunately I will have to reduce its size in order to post it.
Strangely enough it does tend to be OK with absolute minimum power coming from the solar panels, but as soon as the sun comes out it cannot seem to cope.
I distinctly remember getting my electrician to sign and date the ten year warranty card before I posted it off, so I’ve emailed Earthwise and will await their response.
Its excellent that one poster has worked out the issue and fixed it. Maybe Earthwise will send me a new unit and I can return this one for them to repair and sell as a factory refurbished.
🤞
