Hey Everyone,
Have just set up my first Victron ESS system. I set a Grid Set Point of 50W and have noticed the system maintains a very stable ~100W of grid use:
I also tried dropping the setpoint to zero; but still maintains solid ~100W. I understand that the system doesn't maintain perfect setpoint, but I thought it would be closer than this?
These are the settings in my ESS. Have I got something wrong??
Cheers
Just to confirm you dont have any loads on the ACIN side so you're using the internal ct in the inverter to measure the grid?
Normally the internal CT is faster to react than ET112 so I find it tends to be more accurate when using that over the external meter which is odd. Does the behaviour persist even if you turn on loads?
What @matt1309 said. I too am having issues with it not zeroing out my smartmeter and pulling a fair bit of watts, so before you spend money on a CT check the ve config and then if you have access to a clamp meter put it on the ac input and switch off the load on ac out of that’s how it’s wired, Then see what wattage the unit uses according to the manual it uses 18watts with no load Then branch out from there could be parasitic draw, hope that helps
