I agree, logically they should be flipped around and no that's just one month, totals are:

Well it looks like we had it all wrong lads, we are not losing 10-20% on AC-DC-AC but we are making some free kwh using magic, according to Solis 🤣

Manion · 10-01-2023 11:07am

Yep,

But the sensor takes it as difference between values over the time period, which is pretty constant, so that shouldn't be a factor.

You've probably sorted this already Vicrom, but I have a similar setup. Trick for Solis is to switch up DIP 6 on the master battery, CAN should work fine then

Big Lar · 15-01-2023 4:40pm

Hey lads have Seplos BMS and settings in Solis inverter are as user defined, I want to drop the Equalizing charge setting down to 55.5 but cannot figure it out at all. I can change it and when I go Save & Send it just goes back to normal, cant seem to find the setting in the BMS either.

Any ideas

Manion · 15-01-2023 5:31pm

The manual stats it takes it's value from Equalizing voltage under the battery configuration.

Big Lar · 15-01-2023 7:51pm

Thanks for the thought @Manion but I dont see it

Is that not it just there on the left side, fifth down?

That's from the energy tab.. I think

Ah true. I misread. Thought his was showing a power value and in what direction, but the energy tab just shows energy for each node and power energy.

I've been trying to get the tesla-style-solar-power-card working, but it's almost too smart

I've it setup, yep it needs a lot of inputs, all my monitoring is done in EmonCMS so I could do all the required calculations there and feed them into home assistant.

Hello, system commissioned today with 6kw Hybrid Inverter. S5-EH1P6KK-L

I noticed that it is prioritising battery charging rather than house demand. I haven't found how to change this around. There was a period during the sunshine today, that it was using some grid power to meet house demand while charging the battery at max rate from PVs.

The Solis apps show in 5 minute cycles so you need to check the inverter screen for a true reading. They also fluctuate readings between things when under high loads for a few seconds so it might look like you are using power from somewhere or sending it somewhere but it might be just the inverter reconfiguring the loads on screen.

ELM327 · 26-01-2023 10:01am

Yes, ignore web portal and check the screen

What is going on? Battery is being charged from grid every couple hours?

The inverter was set to charge from grid for one hour at 1am. See screenshot from couple days ago.

I turned charging from grid off yesterday, and now this morning it is doing this?

rameire · 01-02-2023 9:00am

looks same as mine,

its to bring the battery back up to the SOC from the FOC.

axe2grind · 01-02-2023 9:16am

I can understand that, but why discharge/drain to house at c100+Watts in the intervening periods. I thought the battery would near enough stay static.

axe2grind · 01-02-2023 9:41am

This is my Mum's system. I have the same battery and inverter, and the underlying discharge is c0.037kw. My Mum's is c0.110kw.

Do we want backup supply on disable or enable? This setting relates only to feeding a back up plug beside inverter??

What does it mean by optimal income?? Disabled? Is this optimal incoming power to battery? Ie charging from grid, and I need to enable to charge over night?

poker--addict · 14-02-2023 5:58pm

Guess this all looks ok? And next step is to make sure it stops discharging at 20%

anyone know what this 'Grid Side' icon is all about on the web portal ?

Never saw it before today.

poker--addict · 15-02-2023 3:14am

So battery appears to stop discharging, but it is charging from the grid at just 200W per hour. Why might it be trickle charging?

it appears to have started the 200w trickle once it depleted and not during the overnight grid time?

yankinlk · 15-02-2023 7:19am

I thought that was normal behaviour of any battery once it reaches the bottom percentage? SOC I think? Mine is 10%. If I go below it charges back up to that....

poker--addict · 15-02-2023 7:40am

But I want it to fully charge at night, will need a far higher rate of charge

yankinlk · 15-02-2023 11:14am

https://www.boards.ie/discussion/comment/120242491#Comment_120242491

Yeah sure. So do I. But battery is meant never to go to zero empty. System normally setup to keep it at a minimum capacity at least

poker--addict · 15-02-2023 12:51pm

Can any one with a solis inverter and lifepo batteries please share a photo of their Solis inverter settings. Particularly helpful if using a JK BMS to manage it and not using inverter to define state of charge

at moment inverter thinks battery is at 53.5V and won't charge it with the excess solar. BMS is only 52.7 V and suggests 42% charged

brendandonlon · 21-02-2023 10:22am

Hi all - I have a "charging battery at night / not draining the battery when charging EV" settings question…

Thanks to your help, I now have remote access to the Solis settings controls without having to crawl into the attic - so I'm now looking at creating my charging / discharging settings with two goals:

– Create a battery charging window during smart meter night rate period in winter; I'll use this to tinker with the length of time or the charging current every few days to ensure I'm avoiding using day rate from grid.

– Create a "protect the battery" charging window at s set time every night (probably the night boost 2am to 4am) to allow for EV charging at cheapest possible rates. Based on all the learnings here, I know the trick is to set a charge period with a current of zero or close to zero, so that the Zappi can't pull anything from the house battery during this time period.

However! I've discovered that my second period charge / discharge settings don't seem to be actually adjusting the charging current. It's sticking with the charging current from the first setting.

You can see below I've got 30amps going in or an hour at 10.30pm (I've set it low to avoid the Solis inverter fan coming on, as the inverter is above our bedroom in the attic…)

But when the second charging time period comes up, the charging current stuck with 30amps, rather than changing to 1amp, as I asked it to.

I've tested this with a couple settings - no matter what amps I set as the output for the second interval, it sticks with the charging current settings from the first interval.

Any ideas?

The app defines three different charge periods, but my inverter screen only permits a single charge current to be defined for all three.

I suspect this is what is happening here. Perhaps Solis will introduce this in a future firmware version.

yankinlk · 22-02-2023 4:39am

@brendandonlon I can't do multi period charge rates either, maybe it's the firmware version ... I agree with @Jonathan maybe futures.

You can still achieve what you want by charging all night thru the 2am window to 8am. Battery won't discharge doing the charge window. Even if it's full, it will just stop charging but not discharge. And if you want it to say finish before 2am then just adjust the amps.

Why not charge the battery and the ev at 2am...is it just the noise of the fan stopping you? Maybe we can come up with a solution for that....

brendandonlon · 23-02-2023 8:50am

Thanks @yankinlk and @jon1981 - that makes sense. I’ve actually raised this as a ticket with Solis support, so it will be interesting to see if there is a fix,or it’s just another quirky difference between the UI on the website vs the UI on the inverter itself…

However, now that I’ve been tinkering with the charging settings for a few nights, I’m more confident that I can get all (or most) of the night-time charging done within the 2am to 4am super-low night rate period - at the same time as charging the car, as @yankinlk suggested.

I actually thought it wouldn’t be possible to pull enough power from the grid to both feed a 7kWh EV car charger and top up my Pylontech batteries at full-whack at the same time. But this is what happened on the first night. (The inverter stuck with the charge rate of an earlier time period in the night, even when I had told it to send nothing to the house batteries between 2 and 4am). It looked like the house batteries were filling at at rate of 5kWh when they were charging at a rate of 80a - given that my total Pylontech capacity is 14kw, that should be plenty for two hours in winter.

Given this, I actually don’t think I’ll need to send more than 30a to the battery during the 2am to 4am period to keep the house off-grid during the day for most of the year. But if I need to dial this up in winter months, I suspect I can get used to the fan noise. It woke me up the first night - but that’s because I wasn’t expecting it, and in my sleep-deprived state I was then shocked to discover the battery and the car were both being filled at max rate at the same time.

I’m presuming it’s OK for the inverter and the battery to be filled at max rate like this? And that it’s OK for the overall load on the house to be pulling this much power (approx 13kWh) from the grid? And that the huge rise in operating temperature of the inverter during this period is OK?

Snippet below will sync the inverter time with your PC.

from pysolarmanv5 import PySolarmanV5

def main():

   modbus = PySolarmanV5("192.168.1.100", 12132154)

   print(modbus.read_holding_registers(register_addr=43000, quantity=6))

   time_now = list(map(int, time.strftime("%y %m %d %H %M %S").split()))
   modbus.write_multiple_holding_registers(register_addr=43000, values=time_now)

   print(modbus.read_holding_registers(register_addr=43000, quantity=6))

Yes all fine. My max (on a standard 12kva domestic connection) draw on a nightly basis is 15-16kW. Charging the car at 7kW, batteries at 2.5kW, other batteries charging at various rates and also domestic appliances running.

The solis will tell you in the info screen, think its the third page, how many amps are being drawn from the grid. Keep this at or below 63 and you'll be fine. Assuming you have a standard 63A CU 80A ESBN fuse

tnegun · 23-03-2023 5:16pm

I'm using pysolarmanv5 to try read and set power limiting on a Solis 4g inverter. I'm getting "umodbus.exceptions.IllegalDataAddressError: The data address received in the request is not an allowable address for the server." when attempting to query the register storing the current value. Does this just mean the register I'm querying doesn't exist(I can query others)? Or could it be I don't have permission to view it?

Jonathan · 23-03-2023 6:44pm

That's a 0x80 Modbus error reply from the inverter. Are you 100% sure you have the right Modbus function (input vs holding register)?

tnegun · 24-03-2023 12:52am

I'm not sure I've tried to read it with

modbus.read_holding_registers(register_addr=43051, quantity=1) and

modbus.read_input_registers(register_addr=43051, quantity=1)

but both return the same error

mickey15ie · 24-03-2023 8:13am

Morning All,

I have 2No. 5KW Dyness Batteries & a Solis Invertor. Is there any way to remotely access the invertor to set the times the batteries charge from the grid?

Ya. Open a ticket with solis and they will enable it in the soliscloud app and website. It works only on the web for me not sure why. Click on inverter and look for inverter control in upper right.

graememk · 24-03-2023 8:34am

Needs the newer logger though. It can be done locally on the older logger. But it's dealing with some code& automation

Are those registers correct? They look to be for the Solis Hybrid. From what I can recall you have a Solis String inverter?

Try the registers listed in Section 5.6 of the PDF below (note they are off by one; 3000 = 2999 etc).

Yes you're absolutely right it's a string inverter I think I went down a rabbit hole looking for the register. It looks like I'm after - 3050 Power limit actual - I queried register 3049 and got a value back of 11000 so it currently set to 110%? Or have I got it wrong?
