Thank you Leshen

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

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%

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.

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.

My electrician says he is using Shoto batteries with sunsynk inverters. I looked the battery up and it's quite a bit cheaper than sunsynk batteries. What do you guys think? Will it be a good idea to go cheaper or will it cost more at the end of the day?

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

So when I do my install I must have the grid neutral and the inverter load neutral separated in my DB? So there will be 2 separate neutral bars? And then ofcourse install a relay. Does the relay earth have to go to a ground spike or can it go to the earth from the inverter/municipal DB earth?

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?

I'm new so forgive a simple question. I'm starting to collect 18650 batteries slowly. What should I get to charge/discharge the batteries to test them? Ohm and mAH is also important I suppose.
