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

I have the 5kW Sunsynk inverter.
Would like to add another 4x 465W, 2x facing east, 2x facing west) JA solar panels. The same as the 6 currently installed.
The are rated at 50Voc Open Circuit.
I suppose linking the each set of 2 panels in series then. The the 2 strings in parallel.

It's like you've been ignoring this piece of info every time it's posted. Let me put it for you in simple maths:
2 x 50V < 125V
 
I came here to ask the same question. I forgot how to work out the max number of panels per MPPT. My ex-brother-in-law is looking for a system. 16kW Sunsynk. How many panels can he install per MPPT?

According to the Sunsynk specs the max PV Input voltage is 450v. So if I say we go with some 545w Canadian panels for instance with a VOC of 49.4V, would that be 10 panels per MPPT, or rather play it safe and go with 9 panels per MPPT?

Definitely go with 8. While one can safely overspec on amps, you don't want to take any chances on voltage. Also remember colder weather increases voltage so you want to leave room for that.

Edit: if your panel specs are correct (i.e. 545W at 49.4V) those panels are about 11A. That inverter can do 26A on each of the 3 MPPT, so one can easily parallel those panels if he wants to go for more. As an example, 2 strings of 5 would work well.

Edit 2: so max of those panels would be 2 strings of 8 per MPPT.

Got it thanks
 
Hi guys

Long time lurker and learning from you all. I have finally got the guts to commit to a 8kw Sunsynk, 2x5kw sunsynk batteries and 5kwp solar. Installation is on Monday.

My average kwh a month is roughly 600 +- looked at my COJ bill for last 12 months and captured in a spreadsheet.
Just completed my prepaid conversion and the UI device is a great piece of kit that shows current watts consumed. The installer said this is the new type as he also replaced the box outside. I already had a smart box outside that was replaced 10 years ago. So not sure how new this is?

So, i switched on a few devices this morning to see how much electricity I can use at the same time simulating a possible real live scenario.
switched on geyser + base load - load jumped to 3400w
switched on oven - load jumped to over 4400w
switched on kettle - load jumped to over 6400w
Managed to peak at just over 7000w

We will obviously not use our electricity like this but wanted to see the figures to get an idea.

My dilemma now is, what do i put on essential and what not? For me it seems like i can have both my oven and geyser on essential load. What do you guys think? I will probably never have both on at the same time. Looking at controlling my geyser with smart switch to run once a day during sun hours.

Am i crazy to think this? Thanks.

I have a similar setup. I left everything on essentials. No splitting of loads. Works great for me.
I have 2 geysers that run staggered during mid-day for an hour both. Both are on CBI Astute timers.
 
Can i asked the installer to add a CBI astute while they busy? is it quick to do the install? Need to buy one tomorrow.

I have 2x geysers on a changeover switch and timers so they run on non-essentials normally but in a pinch I can isolate one and run it off essentials. Wasn't expensive to add the changeover switch.

Welcome to the mad scientist society!

Awesome system you're putting in!

I'm have the 5kw inverter, so I had to pick between what to add to the essential list and non-essential.

If you have the space to cover your peak load, then why not add it is my view - one thing to be careful of though is making sure you and your family are aware when there's load shedding so that you don't have geysers, oven, aircons etc running off your batteries (with stage 6 and potentially higher stages looming, you want to keep some space in those 2 x 5kw batteries).

We put one plug in our kitchen on essentials and it's been amazing - the other night our load shedding was "extended" as usual because of a fault, and we were able to run a pressure cooker to make a full dinner. For me personally, that's a massive win.

Enjoy man!

Hi and welcome to the wonderful world of self generation. I also have everything running on essentials, with a couple of smart switches making sure the heavy loads are not on at the same time.

CBI Astute is very quick to install.

About 2 weeks. Not sure if it was cos it was in December and I didnt follow up or chase.
I guess thats the problem when you are your own installer and not approved.

Just got the confirmation now that it's been done - thanks man!

Interesting to see that while I've updated the time to refresh every 60 seconds - the graph still only shows every 5min - do you guys know if there is a way to change the graph to also reflect every 60 seconds.

@RonSwanson - any other cool settings you found by having advanced access... I feel like a kid with a new toy all over again!

The CBI's are very quick to install, shouldnt take more than a few minutes. I'm sure they wouldnt mind doing it while they are there but it is easy enough to do yourself. I have installed 4 in my house

Make sure you install a plug point on non-essentials for your prepaid keypad as it cant communicate through the inverter.
I only converted to prepaid after my solar and I had all plugs on essentials. I had to install a new plug point on non-essentials to get my prepaid keypad to connect to the meter.

It can communicate, as long as the grid stays up. The plug on non-essentials is to ensure that the keypad and meter are always in sync.

The problem is when the grid goes down (and takes the meter with it), the keypad stays up and it can go out of sync when the grid comes back...

The graph at the bottom is for an overview. Go "Equipment" on the top bar, then choose from a range of graphs under Output, Input, Battery, Grid, Load and Custom. In "Custom" you can pull graphs of up to 10 parameters of what you want with 60s granularity.

Another undocumented feature is on the inverters' interface, in the six block Information screen, press and hold Enter to view the inverter's AC and DC temperature values.

How do i do this with existing plugs? i have 4 plug breakers in DB board for the entire house. how do i isolate one plug e.g in the kicthen?

Apologies if this has been asked before, but how did you convert to prepaid? I'm also ditching the post paid once my solar panels arrive.

These devices should be added to calc peak.

Washing machine
Tumble dryer
Toaster
Air fryer
Heater
Stoveplate (unless you have gas)

If you have everything on Essentials (like me) you have to be prepared to manage 'cos you have no room for pass-through and have to keep peak use within the inverter range.

Thank you for that. I will run some more tests.
My peak load can never go above 8kw if everything is on essential, correct?
Can you explain the pass through scenario please? Let's say i have stove and washing machine on non-essential. Can my peak go above 8kw, the rest will pull from grid?
