Another Solar Journey Thread

yeah looks like CT is placed either in the right place (incoming Eskom feed) or is facing the wrong way or is not working properly

If it was facing the wrong way it should be showing negative values correct?
 
Everything is complete and looking good.
Thank you @Mzezman for the screenshots.

The issue was that the CT sensors was placed in the bottom section of the inverter where the pins are. After chatting to the installer and showing him that non-essential loads are not showing up, he moved the CT sensors inside the DB board instead. This solved the problem.

Glad its all sorted - a number of installers do that (put the CT inside Inverter) which negates the whole Essential vs Non-Essential setup.
 
I have a new set of questions.

1. Is it possible to power the essential loads from the battery and non-essential loads from the grid at the same time without changing the system mode to zero export & limit to load. Basically I dont want the non-essential loads to use up my battery in the evenings but I also want excess PV to power the non-essential loads in the day.

2. Is it possible to update the logger invterval to less than 300 seconds?

3. How do I know if I have the latest firmware for the inverter and logger?

3 - check this forum post
2 - Do you have the Solarman or Sunsynk logger? If Solarman then i don't think its possible. Not sure about Sunsynk
1 - The only way that i know is via the system mode as you mentioned... Its possible through automation tools like Solar Assistant + Home Assistant, but there is no inherent way on the inverter. Unless (and its a bit gimmicky) you set the non-essentials to come on at a time that the work mode is using grid power vs battery

Thanks once again.

I guess I will schedule the non-essentials to come on during the day and keep battery charged for most of the day.

Almost there. Just a few small issues to sort out:

1. One of my geysers is tripping since they connected everything up.
Click to expand...
Rookie mistake. The probably have the geyser on the non-essentials side, using a neutral from the essentials side. These cannot be mixed, get them to cut the neutral over to the correct side.

milan188 said:
2. The non-essential load is not showing on the inverter. I believe it may be something to do with CT sensor. The "Limit to load" system mode is unticked.
Click to expand...
Again, probably the mixed neutral issue.

3. I can't change the data logger interval on the website or app I think only the installer can change it.

Get them to give you "CEO" access, if they will allow it (dependent on your support contract)

4. The inverter firmware probably needs an update.
Click to expand...
Get them to order one through the portal.

Question - The SOC on the battery info bounces between 99% - 100% is that a problem?
Click to expand...
Maybe, maybe not. If more than one battery then it could be balancing. Is Comms good? LiBMS screen showing what it ought to?

Looks like it. But it is sorted now. My DB is a bit messy behind the covers.

The issue here was the CT sensor needed to be placed before the inverter

He said he will change it to 60sec which I am happy with

Looks like I have the latest one based on posts on Powerforum.

Everything looks good. Will check again today.
 
Not sure if this battery fluctuation between 99% and 100% is normal.

@RonSwanson @Mzezman how does your SOC look


There's a small outflow of 30w from the battery to the inverter.

How do you know that it's going to the inverter? To me it looks like those Greenrichs are balancing themselves, it will probably disappear after a day or two. Interesting that there does not seem to ba a slowdown at 88-90%, Pylontech and Hubble have it.

You need to do a custom graph with PV, Grid, Aux, Battery and Load watts in it if you want to find out where it's going (if anywhere at all).

i echo Ron that it may just be balancing as this is a new install. Mine have gone through multiple cycles but also they are a different brand (Dyness 0.5c) so they may behave differently anyways
 
@Mzezman just had a look at my flow diagram on the inverter. My load for the house icon is not showing correctly. When there is no non essential load the amount is showing - 65000W then when I add a 4kw non essential load it goes to - 61000W.

It is not impacting anything (the stats and diagrams all look fine). If the CT coil was the wrong direction it should just show the negative of the non essential load.

Any ideas on what's the issue.

Limited space and more expensive because it was going to be on a flat roof.

I am not too worried about that. My usage during peak times is not too high and prefer the longer hours a East West config gives. The installer showed me some data of similar configs and I am happy with the expected performance.
Click to expand...
I agree with longer.


I have 8 x 545w panels north facing and def want to place other 8 EW for longer hours.

Or maybe another 8 North facing but then 4 or 6 panels EW.

But before then 2 x 5kw batteries.

But probably 2024 as 2023 other minor priorities.
