Hi everyone. I have a question. 

Say you have load on essential and grid(non-essential) and you setup the timer to run the batteries down for a bit in the evening, if the grid is still on will the batteries supply both loads? 

Yes,it will 

If that grid is loadshed, will only the critical loads be powered? Can you choose to power one or the other with the grid present or will it just power both ? 

 

Yes as I understand when loadshedding comes only the critical loads are powered. 

@Steve87, you are right, didn't notice the op saying grid is down

Tariq my original question was with the grid still on. Will the battery still feed non-essential loads if you set timer to run batteries down in the evening. 

From my very limited knowledge of the Sunsynk & it's architecture, you cannot use that battery to power the non essentials at all. The only part that can reach the non essentials is the PV. The main reason for this is that this employs a Grid Tied architecture. It's an Off grid machine & a separate Grid Tied machine in one. The output of the Nonessentials is the Grid tied output & the Off grid out put is the Essentials. No physical way to bridge theses two to get the benefits of one or the other. 

But I must admit a very good design indeed. However, I still prefer to be able to power all the loads as I choose.

I'm not sure about that. As when used in some countries that don't have loadshedding you can purchase power at night to charge your batteries and feed it back during the day when power is higher. These setups don't even have PV. 

I believe batteries WILL power grid tied loads but I need to make 100% certain first. 

That is the Golden question, could we please get someone who can debunk this for us @Leshenthis is your chosen Equipment...Can this machine power the loads from the battery as stated above to the non essentials or is that only reserved for PV & Grid blending??? Sorry to put you on the spot but it's a very intriguing question & will do a lot for the overall understanding of this already well engineered machine. 

I believe I read on this forum that you can put your non-essentials on the AUX port of the Sunsynk and then based on settings on the inverter you can send power via the AUX port under certain conditions? I also believe that you can't power non-essentials on the grid side of the inverter when the grid is down. This opinion is purely based on what I think I read on this forum. 😅

Correct. You can't when the grid is down. 

When grid is up PV can feedback to non-essential. The big question is can battery feedback to non-essential when the grid is up?

From my reading it can but I would like to confirm 100%

It can and does. In fact, it cannot not. (unless you disable it sending power to non-essentials altogether)

Hi All

So I think you can use the aux port and stipulate the amount of load you want to run off it for non essential but once grid fail there will be no power to non essential loads

So I do it this way ,I feedback to my non essentials thats the geyser and Oven that way  I make the most of my solar energy.  So zero export and limit to load unticked.

Don't you feed to the grid with zero export unticked?

 It should be tick that is applied.

Hi Steve. The battery will power both essential and non essential as in the OP question. The only time the battery will not power non essentials is when limit to load is ticked but then the PV will also not power the non essential loads. 
 

Side note, you can also use battery power to feel back into the grid.

It definitely can

Thanks Leshen this clears up a lot of confusion...

So I think you can use the aux port and stipulate the amount of load you want to run off it for non essential but once grid fail there will be no power to non essential loads 

In the Aux port settings on the inverter you have a %SOC value for when it is to start feeding power from the inverter and then a setting for at what %SOC value it should stop. 

As long as the inverter is connected to the grid and the grid is up, it will power the non-essential items from the inverter until it reaches the %SOC disconnect value as which point it will stop supplying power from the inverter and the devices will get power from the grid. 

If the grid is down it does not/cannot supply power to devices on the Aux/Non-Essential port.

Thank you Leshen

Hi, just to confirm what @Leshen has said above. My set up currently has the geyser on the non essential side. Zero export ticked and limit to load unticked. When the grid is up, I can power my geyser during the day from pv/battery. when the grid is down during loadshedding the geyser will not receive any power. My geyser is on a cbi astute switch which I can schedule to come on during the day to use available pv. What I have done is to set my TOU settings on the inverter with 100% SOC during the time slots that i run my geyser(early morning), This way it will not use any battery for that load and only use grid. during the midday slot the PV will power the geyser unless its not enough and then it blend in some battery power(enough time in the afternoon to recharge back to 100%). This setup has been working well for me besides for some manual adjustments to the timing when loadshedding during my normal geyser time slots...hope this helps.
