All things Sunsynk (Deye, Inge, etc...)

Can the smart people here please explain how I'm being dumb.

On Sunday I had a load of 6KW and battery at 35% (the minimum level I allow during that timeslot). PV was generating 4KW and 2KW coming from Municipal supply.

I then set the battery minimum to 30% assuming I would get 4KW from PV and 2KW from battery. However this was not the behaviour. Battery was being discharged at 5KW and PV throttled to 1KW.

Have I messed up settings somewhere?

The SS/Deye inverter will always use available PV where possible. I don't think you can set it to limit PV even if you wanted to.
Maybe a cloud/shade at the wrong time? Or some weird adjustment as settings were changed.
Not easy to replicate i guess, but worth trying again to test? Or does it use proper PV amount now?

Sounds like you had something that was affecting PV production. Or your load was too fast, it takes time for the MPPT to ramp up.

Thanks. I guess it is normal then, but a little strange.
To give more detail, I have 2x5.32kwh Sunsynk batteries, and the master makes the clicking sound. They are both connected directly to the battery disconnector, with equal length cable (according to installer). And installer used the Sunsynk connectors and added (crimped?) cabling (so not the Sunsynk battery pack cables).
Batteries seem to be performing perfectly fine though, about 2 months in now.

Recently installed and can confirm similar clicking sounds-almost like it turns on/off. I have not investigated it enough, but to me it sounds like switching between charge/discharge. If it was in my house I'd be a bit ticked off at the sound (heh), but away in the garage it's not a bother. Seems to be working fine for me.
On that point, what discharge rate is yours set to?

Same, also find the 8kw inverter fans much noisier than expected, so thankfully it's tucked away in the garage. The sound of free electricity is OK from far away.

I've set my battery discharge max under battery settings to 155A, since I have a 160A battery disconnector fuse and the inverter max continuous should be like 160A? I don't know if I'm understanding this concept correctly but so far so good. However, I have all the slots on the timer settings set to 4700w (ends up being about 5kw actual discharge). So while on grid it remains within 5kw (the recommended 50A per battery), and without grid/PV it will max at approx. 7.9kw.

These limits are safe for me, mostly peak around 6.6kw (geyser+kettle+toaster). Would take some effort between the wife, domestic, geyser and loadshedding to cause a trip.
 
Anyone else have their sunsynk app go down and the inverter now showing the wrong time? Lols

Edit1: nvm, seems it has synced again, been having connectivity issues most of the evening so probably just that, hoping the stats on app fix themselves. Will see tomorrow.

Edit2: stats for yesterday are still broken on the app. Seems I'm missing the Load. I've unticked "sync" time on the inverter basic settings for now.

Sounds like we have the exact same setup haha- also an 8KW unit

Mine is set to 185A (installer did), and the recharge rate is set to 40. Think that needs to change. Fuses are also 160A-seen that recommended from most installs I've read.
So far my max load I've been able to do is around 7Killowats with the geyser (3kW), oven(2KW) and microwave(1KW) + sundry stuff on. Was pulling from the batteries, solar and grid, so have not tried just on battery yet.

Change the bold to 7kw before @Speedster sees it

I changed my grid charge to 40A yesterday due to the terrible weather in CPT on a 5Kw inverter. Have a 200A fuse kit though, so all still running smoothing.

The previous 25A was super slow charging the batteries from grid.

I also believe it is normal operation. It sounds like relays opening and closing. I have had no issues with my batteries since they were installed and it is now 6 months later.
 
So this new update to the web Sunsynk connect app.. Anyone manage to find anything from Sunsynk explaining whether they added any new features or if this is just an interface 'upgrade'?

Haven't seen anything new other than the black and white interface. Would have thought they would at least add some colours to the battery levels

Seems like only a theme change for the website. I can however see what seems to be other people's events. That is not my equipment.

The date at the top of website is also live, so it changes daily. Previously was a set date.
 
Hey everyone, apologies if this has been asked I can't seem to find a direct answer since there is so many topics around ZERO Export to load/ct. What I would like to know is: If you are using surplus PV to power non critical loads WITH an external CT on the AC GRID. Will those loads still be given power if the GRID GOES DOWN?

Scenario:
Its around mid day and you are pulling 1500w on your non critical loads, your PV's are pushing surplus in to the non critical load powering that 1500w load so as to not pull from grid, suddenly at that moment the grid drops completely (I know right?, impossible!) What will happen to the non critical load? will the inverter still power the non critical load (while it has enough surplus PV to do so WITH the grid now down) or will it panic and JUST supply critical load?

Asking in context of a deye 5kw system with external CT.
Thanks all!

No. The grid port (which is used to power non-essentials) is switched off during load shedding.

The moment the grid goes down anything on non-essentials will turn off.

Only loads connected to the load or gen/aux ports can be powered during loadshedding.

Thanks for the quick reply Speedster! I was kind thinking that is what would happen.

Thanks again.

Just got mine installed today
8kW Deye
8x 465W JA Solar Panels
1X Deye 5kWh battery.

The installer suggest we install an automatic changeover for the aux to use excess pv or grid.

Tested at around 16H30 today and maximum we could see was 1.6kW from the panels. North facing, no shading.
He says it will take some time (a few days) to for the panels to reach their full potential. Is this true?

It shouldn't take time, but 16h30 isn't exactly optimal production time
