Terminal3k Posted April 10, 2022 Posted April 10, 2022 I have a 5kw sunsynk inverter. I have noticed that sometimes if everything goes on at the same time then it goes into the red. I know it can handle over 5kw for a short period. What happenes if the ac loads goes into the red for a long period? Quote
Nexuss Posted April 10, 2022 Posted April 10, 2022 (edited) If its on the grid side nothing will happen as its not going through the inverter , If its on the essential side its fine as long as grid is available and the total current is below 35 amps , if you go above 35 amps the inverter will shut down and come back on after a few min.

So the electrician said he separated the geyser. Does this mean it's on the grid side? When I turn the geyser on, it still pushes the ac loads up and takes electricity from PV. Is this normal? Sorry I don't quite understand how it doesn't go through the inverter, but it still shows up on the inverter ac loads and takes from pv Edited April 10, 2022 by Terminal3k Quote

Yes that is correct ,If he separated the geyser its on the grid side ,and yes the inverter can send power to the grid side loads as well . The most simple way to understand this is think of the cable going to the inverter ,it can receive and send power through this one cable. It has a current sensing coil on your main grid incoming wire that enables it to do this and its one of the reasons why this inverter is so awesome ! Quote

Thanks, I assume then it won't heat up the geyser when there is loadshedding? If it's on non-essential then it shouldn't take from the battery? Edited April 10, 2022 by Terminal3k Quote

When you have grid available essential and non essential are both supplied from the battery if necessary. Quote

So I can test by flipping the mains on the DB board and then see if the geyser turns on or not. This will tell me if the geyser is on essential or grid.... Quote

This will tell me if the geyser is on essential or grid.... If you have more PV power than what the geyser uses it can still switch on but would be from PV and not the battery. This is what Nexuss implied that the inverter can send power both ways from battery or PV even to non essentials. When you have a lot of PV any load on the whole DB can get p-ower from PV if the grid is on. Edited April 10, 2022 by Scorp007 Quote
