Did you perhaps take note of how they connected up the new battery? Asking as I might look at getting a third Sunsynk battery. The cables of both my batteries are currently connected up directly to the terminals on the fuse holder. I do not think there will be enough space for a third battery. I might have to look at the cabling method Sunsynk recommends for multiple batteries.

I actually had the same concern, and honestly didn't (forgot to) look. I'll open up the trunking a bit later and look. I suspect they just managed to fit a third set of cables on the terminal but I will check.

Would CT coil being installed close to the inverter in the garage and not by the main DB in the house 40-50m away potentially be the cause? I often see this cited as an issue, but my understanding is that it relates more to systems with non-essential loads of which I have none - all loads on essential.

So could the long cable run affect grid import measured? I.e. by the time the AC reaches the CT @ inverter-side, losses already materialised and CT only records what remains post-loss?

Never paid much attention to how the CT connects and communicates to the inverter. Does it need its own 'connection' to the inverter or will it somehow still 'talk' to the inverter if installed in the house by main DB where AC is dispatched to the inverter?

The CT needs to be installed on your incoming eskom feed, before ANY loads like right by the mains breaker. If its installed anywhere else, something in your DB or circuitry may be impacting the CT. The inverters have their own built in CT's on their inputs/outputs etc. and often the difference that is measured between the inverters CT and the external CT to get your non essential readings.

Of course if you have no non essentials or nothing else between the incoming feed and your inverter then it doesnt matter if the CT is installed near the inverter.
 
Not sure if this has been answered, but hoping someone can help: my 5kw Sunsynk inverter shows loads that are not on the inverter (ie. geyser), as it can feed excess electricity to it (only when there's power though). Does this impact the capacity of the inverter? I noticed it was running at 6kw the other day, likely due to the geyser also being on at the same. Does it mean it's close to tripping or is the load actually say 3kw if the geyser is using 3kw? Alternatively, will the inverter drop the amount it's sending out to non-essentials if it's at capacity to avoid tripping?

It can do passthrough up to about 8(?) kW IIRC. 5 from your DC sources and the balance from AC.

When grid goes down, you're only left with your DC sources. If you go above 5, the inverter will trip. Your geyser being on non-essentials means you don't have to worry about it, but you still need to keep an eye on the other appliances...

Okay, thanks. So when there's power I can go to around 8kw, but without it will only be the 5kw before tripping.

On the non-essentials you can go up to whatever Eskom could handle before. Non-essentials are not on the inverter per say, they just fed from the inverter if set and when possible (grid up).
On the 'Load' or 'essential' you can do 5kw when no grid/AC, and 8kw when there is grid/AC.

I just did a random unscientific test on our new Body Corporate's Deye 5kW inverter. It can comfortably support 4kW of load, while charging the battery at 2kW. I assume there are redundant internal circuits, which function as you describe.

The instruction manual says maximum passthrough current is 35A, which equates to 8kW at 230V. I don't have enough loads to test your 8kW blend of DC plus AC, but that makes sense for a hybrid inverter.

Up to 50A on the 8kw sunsynk.

I didn't have loads and battery was nearly full using the excess pv but it was pumping it all to the grid which is similar to running a load. 916291565.jpg

My head hurts trying to figure out all the circuits involved with solar/MPPT/grid-tied and battery/DC charger/inverter built into one package! These are obviously very capable devices, with the ability to handle more than the 'nameplate' rating, plus a margin for safety and transient overcurrent. Ironically our Body Corporate one is only ever going to be used as a UPS...

Took a look now, they have connected the new battery up to terminals on the middle battery and that battery then connects to the fuses. I guess that makes sense.
 
I came home today, to find that the neighbours have cut down all their trees which stand between my panels and North East! Not only that, but a section of roof that was always in the shade, will now have full sunshine.

I think I need a second string of panels now.

Should have made them install a busbar while they were at it. Maybe when you add the next one.

Downside is you'll need new battery cables, because each battery cable needs to be the same length irrespective of their distance to the busbar. But the benefits outweigh this...

Thanks for checking.

My only concern with that would be the cable length differences. That always confuses me. I would like to avoid one battery being worked harder than the others.

Anyhow, I took the plunge yesterday and bought the type 1/2 cable sets for the Sunsynk batteries. Will get those installed in preparation for the new battery.

NGL, it's a bit strange to have a random draw for just an inverter and expect the winner to get it installed and set up themselves. They would need at minimum battery storage to test it, and PV to really make good use out of it.

I guess somebody might already have a system and just replace the inverter, but what if some random person wins it and then just sells it, sounds like it'll be a pain to try enforce restrictions on the winner.

Would make much more sense to include at least a battery and the installation with the prize, or am I missing something?

It's what I would do.

And if for my new home, I would just buy some storage, panels and installation, around 80K. A great system for just 80K is still better than no system at all.
 
Has anyone had their Sunsynk inverter sent into the repair Centre recently? My inverter had a F20 fault come up and did not function thereafter even after resetting the inverter and battery numerous times. Installer came through and also could not get the inverter to work. Inverter has been at the repair center for over a week now. What is the turnaround time now as i know there was issues previously with long waiting periods for the inverter to be looked at?

Not from personal experience, but word on the street is that it can take 2-4 weeks. Pretty poor service, especially considering the Eskom service in this country, and the initial commitment from Sunsynk (David Drake himself) 3 years ago to provide loan units, which seems to have fizzled out.

Solis have indicated that they will provide a replacement unit if one of theirs fails under warranty, let's hope that they keep their promise.
