June 18, 20215 yr Yea! if you have one or two batteries your settings will be more important, different story if you have many. i like to change my settings often according to weather so the remote feature will be awesome. Edited June 18, 20215 yr by Nexuss
June 18, 20215 yr okay, so I changed the timer settings to the below, the last line being 19:20 with 50% SoC and watched the inverter's clock change over to 19:20 but it didn't start using the batteries to power the load... you can see in the flowchart shows that it's not using the batteries but the values don't add up. PV is zero (correct as the sun is down) but the reading at the CT shows 56W but the "UPS" (inverter load) is 1061W which would've been about correct. So where is it getting the power to supply the "UPS" load? I have a digital amp meter on the line from the grid supply to the inverter and it was showing 4.7A which is about correct for the load of 1102W at 228V.

If you set 50% soc at 19:20 it will get the battery up or down to 50% and keep it there. IF the battery was allready at 50% it would do nothing just like you saw, If the battery was say at 80% it would use the battery and go down to 50%. If it was say at 30% and you dont have the grid charge tick it would also do nothing except prioritise pv to the battery when its in the daytime. If you have the grid charge tick it would use grid to charge up to 50 and keep it there. Hope that makes sense .

Also sounds like your CT coil is installed incorrectly. If the ups loads are supplied from the grid, the CT coil should show this. This is a pic of mine from this morning.

I've had my Sunsynk 5kW 1P installed for just over a week, and am mightily impressed with it. Less so with the dongle and Solarman in general. Often the inverter is offline, and sometimes both the inverter and the logger are offline. The latter may be for lack of a decent WiFi signal strength, but I'm also running a RIOT module, which displays no such signal strength problems.

I had to use a wired antenna as i could not get it to connect with the one the supplied,it was very frustrating lol.
June 19, 20215 yr i have had my Sunsynk for about 7 months, i don't feel the need to modify any settings at all, only last two weeks with load shedding and typical Cape Town rainy drizzly days on end, had to set grid charge to get battery capacity high enough for load shedding
June 19, 20215 yr 6 hours ago, Achmat said: Also sounds like your CT coil is installed incorrectly. I agree the CT should be reading at least the load value when using grid power for the supply. What could in incorrect about the CT installation? It is clipped around the live cable between the council supply/meter and the dirty DB. The only non-standard I can think of the that my CT is extended about 17m from the inverter to get to that DB. It is getting a positive value reading which implies it is the correct way round on the cable at least... It does not run next to any AC cable except at one point where it crosses an AC cable. The CT cable does run along the roof trusses, next to a PV cable though, but I believe it's only AC cables that are a potential issue. Edited June 19, 20215 yr by RhysMcW

Did you ensure that there are twists in the wires, at the same intervals, and in the same direction as the original? This is very important, protects the signal against EMI, RFI and crosstalk.

Reasonably close is good enough, you don't need to use a Vernier.
June 19, 20215 yr It could also be connected at the incorrect points on the inverter. I know with my 8kw sunsynk inverter I had it initially at the incorrect ports on the inverter.

Yes this , we need lots of pictures if you can,should make diagnosis easier.
June 19, 20215 yr 1 hour ago, RhysMcW said: here are pics from this evening I still think there's an issue with the CT coil. It should be reading more power coming from the grid. Can you post a pic of the connection on the inverter? This is mine currently. Not using battery or solar and all loads supplied by the grid.
June 19, 20215 yr And remember to set the grid charge rate in the battery second screen. Some questions from my side: Why do you have Zero Export Power set to 100W? Does your meter trip if if is set to zero? Why are you limiting charge rate from solar to 35A? If you have 2x Pylontech US3000 in parallel, then they should be able to handle 70A. Same goes for the battery charge rate from grid (second battery screen), you have it at 25A.
June 20, 20215 yr 16 hours ago, YellowTapemeasure said: Try this: thanks @YellowTapemeasure, just set to that, will see how it goes tonight. Just curious, the "Max Sell Power" value of 5500, should I set it to that, with having the 5kW inverter?

I set Zero Export Power to 100W based on what I've read on the forums (here and the Synsynk one). I have a pre-paid meter, haven't had it trip out yet but also don't want it charging me for any current that does happen to go go out, as I've heard most of these newer meters do, but I guess I could reduce that a little and see how it goes. But I'll probably play more with that once I've got the CT issue sorted, haven't had a chance to go ceiling crawling yet... For the battery charging, I had it at 35A as the Pylontech specs has 37A but I wasn't aware I could have that per battery, thought it was the recommended limit regardless of number of batteries connected together. I've upped that to 70A now, thanks. The grid charge I had low to potentially use less grid to charge the batteries, but that was a carry over from my Infini (which never really worked well anyway) so have also upped that too.
June 20, 20215 yr Edit , nevermind i did not see that you have a bi directional meter sorry lol Max sell power of 5500 is fine. Edited June 20, 20215 yr by Nexuss
