AC Master V0.00 Error 003

The SBV 4600 has failed. When the AC Plug was in the outlet, there was a loud hum and it never kicked on to charge. AC output also failed to switch on. Solar DC input still works and DC output still works. Opened a ticket Monday via email and no response. Called and left message yesterday. This is 1 of 2 units running Time of Use for me and now I am.down to 1 unit. Not enough to support a 1pm-7pm grid TOU without spending a few days reconfiguring the power design.

I have the same issue. Zendure support respond 3 weeks later that they will replace the SBV.

Looks like there's a quality with the AC Inverter. How Long worked your SBV? Mine worked for about 4 months.

Will the replacement units be newly constructed units, or are they refurbished previously returned units?

Expert, it very much seems like an inverter issue. This one was operating since April, so around 4 months. The first unit "popped" in June, only 2.5 months in. The new unit shipped has a much brighter dispaly and is very quiet. I think the updated/upgraded internals. I still have not received the Home Panel, but instead utilize a Generac 30A gen plug to a 100A transfer panel. A litle archaic, but it was working. Time of use from grid and nighttime usage was very minimal. With only 1 unit operational, i have pulled off of the generator panel setup and went back to extension cords. Kind.of.a.painful mess.

Now, the replacement unit is here and running. I don't know If it's a new or refurbished one. But it looks like it's new.

Same problem for me except I also saw smoke coming out out the unit. It's been off since and it's being replaced 😕

Look for my posting here titled something like "the last update fried my SBV's AC unit". Mine was replaced, too. But the new one has the very same issue: When connected to AC input, but set to not to charge, it emits smoke. I managed to pull the plug before the replacement got fried, too. Hopefully, this hasn't damaged it too much. However, I found out what the issue is: I have protected my the grid built by the SBV by grounding one of the two wires and putting in a RCCB switch. Apparently, though, the SBV's inverter gets fried when one of its output wires comes back via the PE wire, while it is set to not to charge. I have explained this to the support, explained that I suppose there will be more customers doing this, and asked for their engineers' opinion on this. Then my support ticket was closed. 🙁
