I have a 5kw Sunsynk paired with 2x Pylontech UP5000.

I have both my geyser and stove connected to Non-Essentials and everything else in the house connected to essential loads.

Today I noticed that in Solar Assistant despite indicating correctly that my oven draw is on Non-Essentials that its using battery to power it? How and why would it do that?

My understanding was that Non-Essentials will never be powered by battery?

There are many topics that explain this. 

One setting is to lower the Watts that may be used from battery. 

The other is to use the timer to keep the battery at a high SOC during certain time slots without the using grid to charge. 

Try it out at a time when you are using the oven or other non essentials you can see are switched on. 

I hope I remember correctly.

I assume all of the above is related to the timer functionality?

Lowering the wattage is probably not the best solution as I'd still run say the dishwasher quick cycle (>2200watts and consumes 1kwh) at night occasionally

Ideally I'd like for it not to be able to draw anything out of the battery from non-essentials. Not sure how this could be achieved via SOC.

So by using the dishwasher and it uses some battery power you have indicated you have to then use grid during the night to recharge as you need battery recharged at 08h00.

If you set the timer at 90% for a 19h00 to 22h00 and use grid not ticked. Say the battery was at 92% or above 90%. Then switch on the dishwasher and see if the battery drops to below 90% due to this non essential. 

Once you get to 90% it should use grid for the dishwasher. 

Users of Sunsynks can add to this post to help you out if I missed the boat.
