What is it that you're trying to do again? Dynamically derate the inverters to stick within 6kW export limit?

decob · 25-03-2023 7:17pm

Just recently gotten access to my inverter remotely - just looking menu items i have and where i will need to go to switch the (load/grid shifting) setting later in the month or next month to not charge the battery over night... just looking here should that charging/discharge should be that high at 96/97 ?

Yes exactly I'm already polling one inverter and will do the same with the second so until I source a CT that isn't stupidly priced I was going to attempt to derate using the python module. Would you know is the 3050 register writeable?

Jonathan · 25-03-2023 10:41pm

Yup. Its a holding register so FC3 to read, FC6 to write.

Do you need an official Solis CT? Can you get a cheaper one by just matching up the CT ratios? Don't bother with a MyEnergi clamp though. Wrong ratio.

tnegun · 26-03-2023 10:36am

I'll give it a shot thanks, I've ordered the correct spec(3000:1) CT from Ali Express and ordered the Solis CT connector as a sample from Exceedconn. They are very keen to break into the Irish metering market with me as I may have exaggerated demand to obtain a sample for a reasonable price 😅 both are weeks away though.

Depends on your goals. Mine is set low to run all night to charge but i dont have a ultra cheap 3am burst rate... I set mine to 10 and that fills me to about 5kwh to 100% over 8 hours.

Tbh i have disabled it now untill September since its basically spring time light now. But if you have a larger battery you might still fill overnight for a few more weeks.

decob · 26-03-2023 6:58pm

https://www.boards.ie/discussion/comment/120403437#Comment_120403437

No i only have a 5kwh battery - and on a standard day/night rate - so no ultra cheap burst rate...

yankinlk · 26-03-2023 7:41pm

https://www.boards.ie/discussion/comment/120403736#Comment_120403736

Then it that case... If you want to charge all night... Change it to 10... Set charge time to 00:05 to 7:55am in winter and 00:05 to 8:55 am in summer time (ei) ... Different times if in northern ireland! Also check each provider...they might have different night rate times.

If you want to partially fill the battery reduce the rate rather than the time. Low and slow should create less heat and hopefully extend battery life.

graememk · 27-03-2023 7:51pm

Had been having Grid over voltage errors on my dad's solar install, but the grid voltage was fine. Turns out the inverter was reading 27V too high,

Put a support ticket in with solis, on saturday, got a reply back this morning with a "Firmware has updated and calibration has done. Kindly observe the system"

Yep system is spot on, they used the calibration offset and set it to -27 (previous limit was -5) It must have a Modbus register.

I did submit photos showing the problem, (had the probes on the AC of the isolator) Had to tape the Multimeter to the inverter as I ran out of hands.

I've been trying to derate with

modbus.write_holding_register(register_addr=3049, value=5500)

It doesn't return an error but querying the register immediately after shows no change, any thoughts on why not?

Jonathan · 29-03-2023 1:57pm

https://www.boards.ie/discussion/comment/120415811#Comment_120415811

No idea unfortunately. Might be worth changing via the screen first and then scanning the modbus registers to see what you've changed? At least that would confirm correct register and that it takes effect.

graememk · 29-03-2023 6:44pm

Ive something setup using the power % on register 3051 (well thats the one Im calling) but changing 3052 as its 1 off. in the doc i have 3029-3050 is reserved.

tnegun · 29-03-2023 10:14pm

3049 or 3050 offset by 1 seems to be the correct register on both of my 4G inverters. If I get time tomorrow I'll try as @Jonathan suggested and configure the limit on the inverter itself and see if I can find the register that gets updated.

tnegun · 30-03-2023 11:25am

Ok so it's definitely the correct register as limiting to 55% on the inverter is reflected by the register changing value to 5500.

In case I'm doing something silly this is the python snippet and output returned when trying to set to 50%

modbus = PySolarmanV5(inverter[0], inverter_serial, port=inverter[1], mb_slave_id=1, verbose=0)

print(modbus.read_input_registers(register_addr=3049, quantity=1))

print(modbus.write_holding_register(register_addr=3049, value=5000))

print(modbus.read_input_registers(register_addr=3049, quantity=1))

Output

[5500]

5000

[5500]

your writing to a holding register but reading from a input register, Example from my code... (also how do you get a entire codeblock to go into code snippet instead of just doing it line by line?

    if 0<=pwrLimit<=11000:
      modbus.write_holding_register(3051, value=pwrLimit) #set power limit %output
      x = 3051
      val = modbus.read_holding_registers(register_addr=x, quantity=1)[0]
      print(val)
    else:
      print("input out of range")

You mean like above? Just select the text and over on the left side of the "edit box" there is a paragraph marker, in there you can select code block.

tnegun · 30-03-2023 2:07pm

I think it's starting to make sense. I thought that a register could be treated as both input and holding depending on its purpose and what I was trying to achieve. So input register 3049 is not the same as holding register 3049?

I may have used the wrong terminology for the python code too when I said snippet I just meant it wasn't the full script I had just pulled out the lines relevant to this.

tnegun · 30-03-2023 2:18pm

That was it writing to the holding register 3051 allows me to manipulate the output of the inverter! I dropped it to 10% for a few mins as can be seen below.

Jonathan · 30-03-2023 2:39pm

https://www.boards.ie/discussion/comment/120419801#Comment_120419801

Input and holding registers are usually in separate (non-overlapping) numeric ranges. I've noticed that on my Solis, I can query input registers both as an input (as expected) or holding registers (out of spec), so the Solis doesn't seem to implement the Modbus spec correctly.

I'm dealing with just a standard inverter, but if you have the newer logger you can get remote access

jkforde · 31-03-2023 8:06pm

https://www.boards.ie/discussion/comment/120425243#Comment_120425243

yes indeed

1. request remote access from Solis EU support: euservice@solisinverters.com

2. get one of the new data logger sticks

https://www.youtube.com/watch?v=RyjOH5-XK-4

3. click on Inverter in the Device tab in Solis Cloud app, then in top right, click on Control Inverter. the ability to set charge and discharge times and amps if in the Self Use settings

The CT and connection arrived so I'm trying to configure a Backflow Power limit on a Solis Mini-3000-4g but I can't get any limit above 1000w to stick. It accepts it but returning to the setting shows 1000w. The menu structure is different from the manual so I may be on an older firmware version. Under EPM I don't have a CT test or meter type option just the ability to turn EPM On or Off, Set the CT ratio and the Backflow power limit. I've tried configure with the Grid On and Off and also EPM On and Off.

When I switch the EPM Off the backflow setting holds but as soon as I turn it on it reverts to 1000w. I've opened a ticket with Solis but thought I'd try here too! The P_EPM shows on the information screen shows Positive for Export and Negative for Import is that correct so its detecting the CT I'm just not sure of the polarity.

poker--addict · 21-04-2023 10:50am

Why am I drawing from grid and battery and solar panels? Seen this grid drawing the last few days? Is it a brief moment in time as battery ramps up or what setting is the issue?

jkforde · 21-04-2023 10:58am

the Solis Cloud app display is literally just a 5min snapshot of the system's state, better to watch the screen on the inverter for real-time flows. that import is probably just system balancing going on.

poker--addict · 21-04-2023 9:46pm

that was the wrong screen shot !

is 200 watts standard inverter usage? Presuming the 580w -370W in photo below reflects inverter use ?

Mine is getting quiet warm, wouldn't fancy leaving my hand on the steal elements/heat exchange grill at back...?

buzz11 · 14-05-2023 3:50pm

Question for anyone with multiple solis inverters, what is the address setting for each inverter? all 3 of mine are set to 01 but I suspect this is incorrect

Jonathan · 14-05-2023 5:20pm

https://www.boards.ie/discussion/comment/120596381#Comment_120596381

Are they all on distinct RS-485 buses/data loggers? You can condense down to a single RS-485 network by addressing each of the inverters uniquely.

graememk · 14-05-2023 5:50pm

I suspect its just for the loggers, and the inverters arent connected to each other. leave alone.

buzz11 · 14-05-2023 8:16pm

https://www.boards.ie/discussion/comment/120596745#Comment_120596745

I should have described it better, theres 1 hybrid and 2 non hybrid inverters.

The problem is that the backflow limit is not working, even though its set correctly.

The solis support pages are woeful but it seems to indicate that each inverter should have its own address but theres no specific instructions that I can find.

tnegun · 14-05-2023 9:06pm

How are you managing export with an EPM? How are the inverters measuring the export?

buzz11 · 15-05-2023 11:15am

https://www.boards.ie/discussion/comment/120597558#Comment_120597558

the hybrid manages the exporting and should cut its generation when it approaches the set limit.

I’ve opened a ticket with Solis support so will report back. The installers should’ve done all this but they were in too much of a hurry to the next job 🙄

jkforde · 15-05-2023 11:56am

just fyi, Solis ticket support can be very slow (snowed under I suspect) so I'd follow up with them on euservice@solisinverters.com

tnegun · 15-05-2023 3:27pm

If you view the export on the hybrid is it displaying it correctly? I've only got string inverters but once one was properly registering the export (CT in the right place and direction) it worked pretty flawlessly.

Daveq · 04-06-2023 10:53am

Ive noticed a few things with the graphs in my Solis app. Does anyone else find the same?

Time is 1hr behind on the graph but the app refresh time knows the correct time?

Screenshot_2023-06-04-11-42-29-47_fffb7a36b95fd26011ab6c25a1351116~2.jpg

The temp for the inverter is different between the graph and the main page readout.

However, if I add another parameter to the graph, it fixes it!

And one last one, I assume myenergi is more accurate for import/export because it seems to align wih my bill, but quesyia why wouldn't my battery supply all power needed over night? Seems to give half the power needed at a given time. Am I missing a setting?

I have the 5g Solis hybrid inverter with connected Puredrive battery + Eddi/Zappi. I got caught in the myenergi v5 firmware issues yesterday and so had to reset the Eddi/Zappi but managed to get it all going again. Im not sure why, or how it would be related to the Eddi/Zappi reset, but one thing im noticing today is that the Solis is exporting surplus PV rather than charging the battery (battery is at 90%). Ive unplugged the EV and the Eddi is at max temp...

Ive done a lot of searching but am unable to find where in the Solis settings I can change the logic to be - once there is surplus PV it should go to the house and then charge the battery (if battery is <100%). Am i missing something obvious here?

Jonathan · 04-06-2023 1:11pm

https://www.boards.ie/discussion/comment/120676174#Comment_120676174

Any chance you've inadvertently changed the Solis to Feed-In Priority mode.

mag · 04-06-2023 2:20pm

https://www.boards.ie/discussion/comment/120676404#Comment_120676404

its in self use mode.

I have it integrated into home assisant. What I would lke is to put the logic in that once the house is being serviced by surplus PV then the battery needs to be charged to 100% before zappi/eddi and export last.

daughy · 05-06-2023 9:29am

Hi guys, I'm not sure if anyone else has come across this issue, I'll try my best to explain my situation.

I have been back and forth with emails to Solis but they actually can't solve this issue or pretend they know what they're talking about, after my inverter was updated the soliscloud and the app are not showing the SOC of my battery, my battery is a lifepo4 generic brand, not in the inverter list, but even if it was a diy install with singular cells undoubtedly someone has maybe come across or found a workaround for this issue, I'm using user defined for my battery, set the over voltage pro to 54 volts, under voltage pro to 48 volts, over charge to 90% which I'm not sure is working as my battery will charge to 100% and just a little over 54 volts, this might be over charge protection in the event that the inverter charges from the grid and stops at 90%, I'm not sure as the manual for the inverter is terrible.

Over discharge to 20% and force charge to 19%. The DOD at 80%… The rest is just the float charge which is disabled etc,

I can see the history of the SOC in the app, and the soliscloud, I can see the SOC in the main display of the inverter, I can see the SOC in home assistant, but cannot see the SOC in the app or the soliscloud.

It's not a big issue but Solis don't have an option for a diy lifepo4, but did give the option for lead acid before I updated, there thinking is if you pick a different brand than what they want you to pick in the battery list you will void the warranty, I'm way past the warranty at this stage.

I have asked them to give the inverter an update for lifepo4 diy.

Any suggestions welcome 🤗

daughy · 05-06-2023 9:55am

If the inverter is set to over pro at the 54 volts I have set it to, is there a shunt inside the inverter?

I know a full 100 amp 48 volt battery can charge fully each cell to 3.65 volts, and I have seen the voltage just go a little above the 54 volts I have set in the inverter OVV pro, but why will the battery say it's charged to 100% when it reaches this target?

Should the battery say it's approximately 90% or 95%…

Is what I set the over charge % at 90% correct and the inverter thinks at 90% charged it's 100%.. very strange
