The fan would work fine I imagine if it fixed to a heavy weight on top of the inverter to counter balance the fan, problem is that I have the inverter in the utility and the wife already gives out a bout the noise of the inverter fan.
I was actually in a house the other day and saw these radiator reflectors and was wondering if I could put some fins against the wall behind the inverter would I get more passive cooling, the radiant heat from the inverter would heat the plate and cause the air to rise, I think that this may work well for me as I have the inverter 50mm out from the wall already
@Jonathan Have you any idea of what temps you were seeing before the fan install ?

The charging I’m talking about above (up to 80% is actually coming from solar) say from 8am-10am. Then it hits 80% and I stop charging the battery and feed it to the grid until 3pm.
But I am charging from grid at night also because is it’s cheeper (prob not the right word- more financially beneficial in the end) to fill the battery between 2-4 am for 12 cent rather than use excess solar that I can get 21 cent for exporting during the day. So the more I put into the system at night; the sooner I am exporting the following day. I know it seems backwards; but I aM considering charging the battery fully each night even during these times of plentiful solar.
so I’m charging at night based on this rule:
target_soc: >- {% set solar_forecast = states(entity_solar_forecast)|float %} {% if solar_forecast > 25.0 %} 75 {% elif solar_forecast > 20.0 %} 80 {% elif solar_forecast > 15.0 %} 85 {% elif solar_forecast > 10.0 %} 90 {% elif solar_forecast > 5.0 %} 95 {% else %} 100 {% endif %}
ok so 7.5 kWp of panels on a 6kwh inverter.
It clips all the time; on days like yesterday the highest it got was 6337:
if the battery was full that would of been a straight line capped at 6kwh.
take the 18th; there are moments when I spiked to 7251w:

Ahh yeah, I kind of see what your doing now. Makes sense.
I'd have a slightly different opinion myself on that one. I'd max charge the battery at night and not mess about with a 80% stop. Why? Well any clipping you experience will be 100's of watts at most for a hour or two. While dropping to 80% of a (what?) 10Kwhr battery is 2kw give or take.
I also think your clipping isn't a result of having an non-full battery, I think your clipping is because the panels isn't as hot as other days. If I take 3 days this week (including the glorious yesterday) and chart them against each other I see.....
Today (in red) I saw occasions where it was generating more than the glorious blue skies yesterday, esp when the sun came from behind a cloud. I'm not sure that battery state not being full is actually stopping you from clipping. It's just co-incidental.
Certainly with my inverter battery status makes zero difference in clipping/non-clipping for me.
Btw - it's probably pennies either way - but it's interesting to do the optimizing for fun :-)

Ha. You’re really having a hard time believing this one. This is just how things work with a high voltage DC battery. Here are the same days directly from the huawei app; I can export the data if I need to yeah.
And here are the battery SOC for the same days:

Have any Solarman/Home Assistant users noticed a discrepancy between what their Solarman and Home Assistant apps are reporting?
Both are using the same logger data but Solarman is 7KW less than Home Assistant.
I can only assume that Solarman is dropping some data. Whereas, my Home Assistant (running on my local network) is capturing all logger data.
Note - Home Assistant has only been running since the last week in March.

Hello everyone,
I am delighted to have found this forum and spent around two hours reading through a thread from page 1 to 41. Although I have no experience with coding, I have been following various YouTube videos and have successfully used the pysolarmanv5/solismod to control my Solis 3.6 inverter with a DLS-W logger. I have two Pi set up, one running HA continuously and the other running solismod, pysolarmanv5, and mqqt.
I am facing an issue during the setup, where I keep receiving the "No Socket Available" error when I execute the script solismod/main.py.
I believe this was due to the fact that my second Pi was connected to an AP router, which was connected to a switch. However, I have now connected my second Pi to the same switch as the first Pi, which is running the HA system. There has been no "No Socket Available" error for also 24 hours.
Currently, I have to manually check if the script is still running by using "sudo ps -ef | grep main.py". I am concerned that if the script is shut down due to the "No Socket Available" error, then my automation will not work.
To avoid the script shutdown due to network issue, power cut...etc, I have used "sudo crontab -e" to run solismod/main.py at @reboot.
My question is, is there a way to set up a script or something that will continuously check if the solismod/main.py is running? If the script has stopped running or exited, then it will automatically restart the script. Also, is it possible to set up a status indicator on HA dashboard to check the status?
I apologise if my description is unclear. As I mentioned earlier, I have no knowledge of coding, Python, or Pi OS. I am thrilled that I have come this far, and everything is working as expected. This is the last thing I need to ensure that the system is stable. Thank you for your time, and I hope someone can help.
Best regards, Madison
