All things Sunsynk (Deye, Inge, etc...)

Have Deye inverter, option isnt available.

You can get them to activate remote control on the Solarman app.

Just register a business user on the Solarman Business app.

Mines is one slot, 1am to 3am to charge to 60%. From 3pm to 1am battery soc is supposed to be 90% so if we use grid so be it.

With this settings covers most load shedding slots including the 4 hour slots we used to have from 8 pm 12am

Sun usually does the rest during the day to get battery to 100% with other workloads

I haven't changed inverter settings in weeks so that is saying something to me. Nice not to worry about it too much.

Would you mind posting a screenshot of the Work Mode Grid

Told you it's been a while since I looked there .From 4pm and not 3pm battery is when battery is expected to be at 90%

I get an error that it's been added to another plant - probably the installer - how do you remove it?

They need to request them to delink the plant from the installer. You can always grant the installer access as a user later on.

Any idea where the DC temp is measured?

DC is battery temp...

 

[AchmatK]

DC is battery temp...

There's a different DC temp sensor.

The sunsynk has an internal DC and AC temp sensor.

The battery temp is the internal battery temp as reported by the BMS of the battery.

This from the Solarman Business app.

Edit

I don't think you would want to see a battery at anything over 35° so that DC temp in the graph is definitely not the battery temp.

@AchmatK and any of the other SA users, have toy connected your BMS up to SA directly or via CAN? Do you get any additional stats that way?

Currently i have mine via CAN but the plan is to go direct into the BMS - you DO get much more info, cell temps and voltages (average, min, max), cycles etc

Depending on your battery brand this may void your warranty, proving that you connected directly to the BMS could be difficult though.

It it possible to add more rows? Or will this only ever work in 4hr intervals

According to the manual there are only six.

Can someone link me to a post that explains how Grid Charge works again in System Work Mode - I keep forgetting.

Using the above picture.

If I have the battery set to 40% (as per his second setting) - what happens if Grid Charge is not selected and it gets to 40%. I know if I have Grid Charge set - it keeps it at 40% - if Grid Charge is not set - and there's no sun - does it just keep dropping?

It will stop using the battery at 40%, grid charge will ensure it's topped up to 40% and then any load will be fed by grid power unless obviously the power goes out then it will draw from the battery regardless.

So basically, if it gets to 40% - the house load uses grid power until the battery moves above 40%.

What happens if grid is lost, battery drops to 20% - grid comes back up - and grid charge is not selected, does it stay at 20% and use grid power for the house - or does it charge back up to 40% even though grid charge is not selected?

 

[DrJohnZoidberg]

Yes. You would obviously need to have solar coming in then to get it above 40%.

What happens if grid is lost, battery drops to 20% - grid comes back up - and grid charge is not selected, does it stay at 20% and use grid power for the house - or does it charge back up to 40% even though grid charge is not selected?

I've not had experience with this scenario but I don't think it would use grid if not selected for that time slot. There might be some other rule that overrides this to get the battery up to the minimum value but I've not go my batteries that low yet to find out.

It will do that either way.

Grid charge applies to the second scenario. If you have it set to 40% and the grid goes down, it will continue discharging the battery until your shutdown value. When the grid comes back, it will use the grid to charge back to 40%.

If grid charge isn't ticked then it just won't charge back to 40%...

Ah - this is what I misunderstood then - I thought 40% is what it'd maintain from where-ever it could get power. (when grid charge is not selected). I thought grid charge was just the priority.

Assume your batteries are at 50% and the next slot on the inverter is set to 80%. If you don't select grid charge it can only charge if there is more solar than your load. It will not use any power from batteries until you are above 80%.

If you do have grid charge selected when you go into the next slot, it will immediately start charging from AC and solar if available.

Same rules apply during loadshedding. While there is grid power you will never go below the set %. Without grid it will go down to shutdown value. Grid charge only toggles if you want the batteries to be charged via AC or not when power comes back on.

 

[furpile]

I have grid charge ticked from 15:00 - 18:00 and 18:00 - 21:30.

So if the battery isn't properly charged by late afternoon, there's some time to charge it before evening. If there's load shedding in that slot, then the next slot will charge it.

I find this doesn't require any fiddling. The only time I'll change something is to untick those 2 slots when load shedding stops. Which hasn't happened since September...

The only downside with this setup is that when there is bad weather you are charging your batteries from grid every night and then discharging them again in the morning. This uses extra energy for the conversions and adds extra cycles on your batteries.

I prefer to keep the battery charge higher in this case. So use grid power until loadshedding and then use the batteries. But this requires more fiddling so there is always a compromise.

Ok, great - it makes my "automations" easier as I can then just change the grid charge option to maintain a level if there isn't solar - and a load shedding slot is on the way. (I can also use estimated solar to drive this)
