They say it doesn't rain it pours.... Haven't experienced any power outage in almost 4 years but that changed this morning.

2 week newborn needed food this morning and halfway through feed lights die. Apparently grid went down 4 hours earlier and sunsynk went into shutdown at 9% soc. Fault 56

I turned off and on again alarm gone thought power would kick in when there was some light but no. Not one watt coming through DC. It's very overcast but the voltage is 274v and I usually got 400w at this stage with this level of overcast.

It's odd as DC light is on and shows as follows on screen. Maybe everything is just to low and I will need to wait for grid.

Any other ideas?

Needless to say my wife is not happy, couldn't have happened at a worse time with the little one...

Check what your batteries SOC is set to come back on. I think mine was defaulted to 20%.
 
What snotface said, there is a startup SOC that would have been set. Once the batteries are at that level, the inverter will kick on and the load part of the inverter will start working.

Sorry OP, that really sucks. We had that happen plenty of times when our LO was younger. It led to many a miserable night when we realised his bottle warmer turned off and we never noticed, and had to warm up water on the gas stove like primitives while trying to console a screaming child.

Was just gonna say what a weird post from you. :ROFL:
Your system has been smooth sailing all this time.

Anyway hope you get sorted.

Same thing happened to me and I dropped the SOC to like 5% or something just for it to kick in.

The batteries are 9% now and restart shutdown low bat all 5%...





Solar is still zero watts and 280v on both mppts.



They are 6x545 ja solar panels on each string.

Just to be clear inverter appears to be running ok but there is zero solar input and grid is down.

Yeah smooth sailing till today

Zero solar input turned out to be a blown DC fuse in my case

These are all good, I switch DC off and everything drops.
When on
watts zero
volts 280
amps 0.2

Pls note my DC light is on but normal light is not
 
My system is barely getting 1080w solar at the moment. 36 panels. Weather is supposed to be clearing up soon.
My battery SOC settings:
Shutdown: 2%
Restart: 5%

At my wits end did two hard restarts didn't help. The system seems to be on just no solar... Might just need to wait for grid... Unless someone has another thing to try

All sorted hard reset the third time worked!

Always the third time hahahaha.

Glad you are sorted.

Coincidentally, I had to do the same to my neighbors system this morning. Exact same problem. They are away on holiday. And asked if I could check out what's going on. Turns out his units were finished, and the solar was too pap.

Thanks man was a terrible start to the day - whole day seems a blur when its time to feed bottles to be sanitised its cold miserable baby crying and you just trying to hold it all together :)
 
What batteries are you using? As I've learnt what the Inverter thingks and the BMS thinks are two different things.

My Dyness will shutdown once it goes below 15% come hell or high water of what the Inverter thinks and similarly the restart value also needs to be 15% or higher.

Unless you force it into AGM mode there is no way around this. Hence all my values are set to 15% as lowest SOC allowed.

Have you identified what was the cause?

Not sure what your redundancies are, I have generator and 2 x9kg gas and two plate as back up.

Thats just to make sure we can have a hot meal and hot drinks.

Seems like everything overall was just a tad too low and needed a proper restart.

We have gas heaters, and gas two plate as a back up too with battery powered lights were just caught off guard but ready for next time which shouldnt happen again
