Deye Battery Setup pages Read!!!

[HowTo]

@RonSwanson need some info.

I see under Deye inverter Battery setting there is a Grid charge tick setting when the battery has reached a selectable Soc setting.
Nice to have. See attached pic.

Is there a setting under SunSynk inverter also available. Will post my Battery setup 3* pics

You can do that by ticking the grid charge under the Time of use setting for the particular SOC. If the battery is less than that % then the grid is used to top up

Sunsynk does not have that on the battery screen, and it is doubtful that it works on the Deye (being labelled "No Use "). And if it did work, it would be confusing, because as @Mzezman has pointed out, you already have the ability to control battery charge from grid or genny from the TOU settings. So there's no utility to the setting.

Ok next question. If no tick is being used on Grid. No Tick according to manual means discharge to certain level SOC.
What happens if Soc 25% is reached or any other SOC level.. Does it now take from Grid to recharge without being ticked?
See attached pic.

I was worried if you have 3 day of no Sun you will get to point that batteries are depleted. Need something to charge batteries,

For eg if you tick grid charge at 60%, and it goes down to 25% overnight, it will use the grid as a supplement to pv to top up the batteries between 9-11am...

@Mike Hoxbig
Then the best would be to alter all Soc setting to 30% 100% and tick all Grid. If I'm correct at any given time if SOC levels reach 30% 100% the Grid will recharge batteries to XXX% depending how much time was left in that window period.

Then the best would be to have only one rows 11:00 to 14:00 30% 70% SOC and Grid ticked..
Also don't forget Power needs a value.

Then the best would be to have only two rows 00:00 to 12:00 and 12:00 to 00:00 at 30% SOC and Grid ticked..

Remember it uses the grid to charge up batteries to the set SOC for that time period. So if you set all your SOC to 30% then grid would only top up batteries to 30%

Yes, but it will still charge from PV regardless though, and if Gen is ticked it will charge from Gen.

If 25% SOC is reached, during the time period of the first (and last) entry, then it will service essential loads from grid. If no grid, then it will use battery until your shutdown SOC state is reached.

If that's your objective, sure. It's actually easier then to just untick "Use timer".

In which case you’ll want to set the SOC requirement under the battery menu to whatever % you fancy to charge from grid I guess?

Although that setting is Grid Start which makes it sound like it works the other way around.

Are these pages related ? 50% setting to each other. From 8kW SynSynk installer manual. 5kW installer manual use Batterie voltage not so clear.

My biggest concern currently if Sunshine is not there for a couple of day's.
Sun power harvesting is poor.
With 9.2kW batteries in total I can last 1.5 day's. In other words I need to recharge at some point.
Even if I tick both the 80% SOC. I could easy last till the next day.
Then the 50% I refer to are the related? Think @SauRoNZA touched on comment #10

Shutdown is only relevant under grid loss.

So it’s the lowest it will go when there is nothing else.

Would not make sense having your shutdown and SOC time settings the same because then it would simply turn off immediately when the grid power is lost.

Restart as was explained in the other thread is when the inverter will start working again. Your 50% seems very high in that case, but I guess for the lower capacity it might make some sense.

I’d probably make restart 20% in your case.

Remember that under cloudy conditions performance is degraded, but there is still a bit. If your loads are low, the excess generated will always be pumped into the battery. Even with my 6K panels and 5K inverter I have never reached shutdown (which is 21% because I have 3x US3000Bs).
What is your panel kWp again?

Mine sorry for the late reply.
Panels 6*455W JA

OK so you have 2730kWp.

Ok want to get more panels for house project.
Wat to look for? 12 panels in total. 6 this month and 6 next month,
House facing East and West.
