Goodwe 5048 - Sems portal conflicting readings

Recommended Posts

Any one here that has experienced this: Sems portal graphic only goes up to 50% SOC for batteries even if they are charged at 100%. Now with bad weather they are showing 40% but the graphic shows 20% - see pics below.  Should we maybe try a soft reset on PV Master?

Hi all, I also have a Goodwe ES5048, i don't have a battery yet. But i don't understand why my Meter is spiking below 0kw. This is very strange. Please help, maybe it was installed incorrectly. But according to the wiring diagram, the arrow on the CT is supposed to be facing back to the grid and that's how we installed it.

That's normal and not caused by a problem with your installation. When the yellow line is on zero you are not drawing from the grid. When it goes UP you are feeding back into the grid. When it goes down you are drawing from the grid. 

 I often think I would have redesigned that interface, but I can't think of a way that it would be totally intuitive (to me, though I'm now used to it).

Got it thanks, but now what is strange to me is, the load and the meter is the and the flat lining after 6pm, that is when most things are on in the house, during the day, the pv is curved along side with the load, but there is not much on except the spikes you see from the geyser timer kicking in. Somewhere something is wrong with my system, maybe the inverter is confused because there is no Batteries connected. 

If you look at the picture attached, shouldn't the Grid LED be blinking during the day when the solar is on be solid at night when I'm using power at night? On mine it is solid while the panels are actually providing power and at night it blinks when I'm actually using grid power. It does not makes sense15846897042374507830696003339409.thumb.jpg.7b31ed8960c8b22a5bfa03c95468a8b8.jpg

Well... at night the system DOES draw from the grid. We see this about 3:45 in the morning. 

I don't like the app on the phone because it doesn't allow much room on the Y axis and so small fluctuations of power are quite hard to see. Try using the browser on your PC - you have more screen real estate and thus more detail.

The yellow energy LED should blink when you are drawing from mains.

That said, I'm not a technical guy. I have a Goodwe inverter, but in a hybrid setup rather than grid-tie. So I can't give confident information about how the system should behave. But I would expect the energy LED to blink when the inverter is drawing from the grid (not necessarily when the non-backed up circuits are drawing).

If you had somebody install for you, then give them a chance to sort it out. If you did it yourself or the installer does not help, then contact

He is very helpful. He may take a while to get back to you with a solution as he will look at your system's data to try to understand what is happening.

Thanks for the info. This is stressful because my prepaid meter is chowing units as if no solar has been installed. Its business as usual for that prepaid meter. The Spike on the load and meter at night and during the day is the geyser timer kicking in. Not much else is running during the to draw up to 2000w, besides the geyser, it's the fridge, tv, wifi and fire tv stick which shouldn't be over 1000w. But in the evening the load is flat and that is when the load from the grid is running.

Yes, I agree, the inconsistencies is that in the evening around 6pm when the solar panels stop producing power, that Blue Grid LED changes from static to blinking as if the Grid is no long connected, that is not possible as I don't have a battery and I'm drawing power from the Grid. And the SEMS portal show little to no load from 6pm whereas I am using the Grid.

Do a meter test on the app to see if your meter is connected correctly.

Do you have a change over switch to bypass your inverter?

Where are you situated, I know of a Goodwe installer who is pretty jacked and he's an electrician so that also helps.

It turns out that my CT was installed incorrectly, it is now in the right place facing the right direction, my graphs are now on point. Can't do a meter test without the battery it seems.

Yes please get me his details. My Ezmeter and CT are now set up correctly, now I have a problem with the Battery, I was having trouble sourcing a Pylontech or Dyness so I opted for a MaxLi 3.3kw LiFeP04 battery and it's not supported so I had to self define but it looses sync every 2 days. Inverter says battery is 68% and the battery bms says it is 10%.
