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

I get the same now and then on the one UP5000 battery.

Battery two in the battery bank of 6 batteries.

If the temp was really that high then all of them would have similar temperatures so I think it's just the sensor on this one. View attachment 1871553View attachment 1871554

Strange, in my case this specific battery has the lowest temperatures and cycles of the three I have, the other two that are cycled more and 'used' more don't have these temperature spikes. Hopefully just a sensor fault as the cell temperatures seem to be fine.

I had to go to swap out my communication board it took me longer to drive there then for them to test my one and issue me a replacement board.

Im about 10km away from them

those little com boards? the rs232 ones? its dead simple to repair, its a smd cap that shorts to ground, i'll try find the repair article, its literally just using a tweezer and popping it off

So this is the newest of the batteries in the bank.

Whenever I added a new battery the new battery is always added as battery 1.

I recall that pylontech manual indicates that any new battery should be the first battery in the bank.

I'm planning to finish my battery bank by adding another 2 more UP5000 batteries which go I into position 1 and 2 in the bank.

Its pretty much what they seem to do when they replace them , but meh why must i do it if they going o do it at no cast

Figure this as good a place to ask without starting a separate thread.

We're renting out our old place to family, it's got solar installed, was there when we bought the place and worked well for a good few years now so we've never really messed around with it.

So apparently last night the power went off; nothing tripped, no obvious issues, they did have microwaves and kettles on at the same time but nothing crazy.
They moved that changeover switch in the pic attached to city power and everything came back on. And when they move it up to Inverter Up the power goes off.
That switch to the right, the load from inverter switch, for some reason I feel it was up and is now down but they say it feels like it can't move back up - they try and it feels pretty stiff.
Everything else appears OK; the inverter shows solar being generated, even shows like we're running on solar.
Any ideas?

We've reached out to the company that installed it but not sure they still exist as we've had no response just yet so figured I'd ask here and hopefully someone tells me Sepeng, you're an idiot, just do step 1 and 2 and you're OK. Else we'll just get someone out there to have a quick look.
Or you can just call me an idiot with no further steps I'm OK with that as well.

Yea going to be that load from the inverter breaker, might needs to be replace if it does not want to go up

With the "inverter load" switch in the off position and the changeover in the grid position all your circuits are now being treated as non essential loads (with no essential loads)

This is why you are seeing PV still being generated and used to supply the loads. If the grid goes down the system will not supply any load since they are all now non essential loads.

If you turn the "supply to inverter" to off then you will be using grid exclusively.

It is not clear from the picture, is that green led on (lit) or is it off (it should be off, since the " inverter load" breaker is also off) ?

for those that own these different makes, is Sunsynk the best make to get for just a normal to largish home installation with batteries? Sunsynk inverter + Sunsynk batteries

there are so many makes and models out there

Not sure which three you refer to, but Sunsynk end Deye are identical (apart from minor firmware differences). Deye is the OEM.

just thinking about brands, everyone has different ones and if they had to do things over would they still choose what they have or change..

I have a deye. If I had to do it again I'd just pick whichever of the two is cheapest at the time keeping in mind that since I use HA, I'd prefer the one with the Solarman dongle.

Sunsynk is a reseller of Deye hardware and build their own version of the firmware/cloud software. Its a smaller company than Deye.
These days if I had to buy I would go for Deye over sunsynk if that hardware was my choice.
Another solid choice would be a Solis inverter.

 

[wingnut771]

I think @Lupus is happy with his luxpower. They seem keenly priced too. Cheap enough to buy 2.

For me, I would still go with a deye but I want to spin my spinny meter backwards.

it depends on what you want each have features that the other may not have (but also your installer and you should know how to install and set this up as i see lots of people dont make use of this) I only have personal experience with Deye . Sunsynk and Luxpower
between Deye and sunsynk they the same my preference is Deye (app is better IMO) but whichever ever of the 2 is cheaper go with that one
Luxpower is good as well but i find their app a bit cumbersome
I went with Deye and at the time sunsynks app was better but deye has improved a lot , if i were to do over i would go with Deye again

We have a SunSynk inverter and if I were to do it again I would seriously consider a Victron system since their pricing has become a lot more competitive and their functionality is fantastic.

That's an interesting view. What can the victron do that your Sunsynk can't?

That's an interesting view. What can the victron do that your Sunsynk can't?

One of the biggest things with the Sunsynk, like many other inverter systems, is that once you have maxed out the MPPT's it is difficult or complicated to add more PV arrays. The Victron is almost like a Lego set, need more PV arrays, just add another standalone Victron MPPT to your existing system. Sure, you can make a plan with micro inverters via the Aux port or something with the Sunsynk but the Victron system is a lot more flexible and expandable. I also prefer the VRM portal to any other inverter management portal I have seen, especially Sunsynk's standard portal or app.

I understand that for many they have more than likely spec'd their system well and won't need to expand in the future but for us, our roof orientation is such a mess that adding more panels to our existing PV arrays will see us get a bit better yield but an entirely new array on another part of our roof is not possible with our Sunsynk inverter.

Saw something interesting in the graphs yesterday. The garage were my Sunsynk inverter is located got rather toasty and I think it derated my PV production at around 11:30 and again at around 12:30. Not a cloud in the sky and I can only think it was heat related on the AC side of the inverter.

Put aircon.

Put aircon.

I have placed a small USB fan in there for now to blow over the heatsinks and see if that helps.
