January 16, 20242 yr Specs: Sunsynk 8kW - FW M 6.0.2.4 / S 1.7.2.4 / C E.4.3.0 Battery: 2x Freedom Won eTower 5kWh. Seem to have a strange issue that I haven't observed before, my inverter is bouncing between charging and discharging when getting to the SOC set on my timer. Recording of it doing this below. Any idea on why this may happens? Timer Settings:

Any idea on why this may happens? Timer Settings: Try setting your first and last time to 00:00 (midnight) and let us know if it sorts this problem out. That's what worked for me on my unit with similar symptoms. I've seen this fix both my Sunsynk as well as others' Deye's so it's presumably a bit of a firmware bug on both.

Unfortunately not, ended up chatting with Freedom Won, they updated the batteries firmware, couldn't test though as the batteries were already full. Big props to Freedom Won for their support. It was lighting fast and the gent that helped me was knowledgeable. I initially logged it with Sunsynk, the agent logged in, he changed all my SOC to 90% and enabled grid charge for all slots then told me it's "fixed"... 🤦♂️ I also changed my aux back to an output as I had it as a gen input, either that resolved the issue or the battery firmware upgrade fixed it. Rock solid again 😃 Edited January 22, 20242 yr by spotity
