July 18, 20223 yr Sorry if this is in the wrong place since I have installed my inverter on Sunday I am unable to read my pre paid meter. it shows error -30- I have tried all the plugs in my house, inverter side and grid side but nothing seems to work. If I go to my gate motor in the front of my property and plug it into a socket then the meter reads just fine, if I run to my house before the meter battery goes flat it will sit on a reading without changing and then eventually go into error -30- I have tried unplugging the ct coil from the inverter to see if that helps, but it doesn’t. because I don’t have solar I am testing the work mode out so I can cycle my batteries. I have ticked to not export to grid, I have an 80watt trickle set. I don’t know if it’s something to do with my wiring because at this point it’s my only explanation. please excuse my quick drawing. But it’s just to show you how things are connected

July 18, 20223 yr The inverter blocks the powerline communication. You have to install it on a non-essential circuit.

As in under my earth leakage as per my drawing or like under my stove or geyser circuit breaker? but would not that restrict flow to my geyser or stove when I have pv connected because then the ct coil will restrict power to those circuits? Edit: Wait, are you talking about the ct coil or the plug in meter? The plug in meter is connected on one of the non essentials circuits on circuit breaker for my non essential plug points.. the plug point is not on my load side for the inverter because i have my crypto miner on it. The grid feeds my crypto miner Edited July 18, 20223 yr by Derek Ramos
July 18, 20223 yr Yes, I am talking about your meter. Does it work when you disable the inverter? BTW, I hope your drawing is incomplete and you actually also have an earth leakage after the inverter.

I tried removing the ct coil wires but didn’t work, I will try the inverter. 13 minutes ago, P1000 said: BTW, I hope your drawing is incomplete and you actually also have an earth leakage after the inverter. Yes, I have quite a few protection devices going into the inverter and then going out the inverter to my essentials are also a few, earth leakage and surge, earth/ neutral bond relay sorry the drawing is basic just so you can see how I’ve wired everything up.
July 18, 20223 yr Author 1 hour ago, P1000 said: Yes, I am talking about your meter. Does it work when you disable the inverter? I switch my change over switch so my essentials can run from the grid, turned the inverter off on the side button, then switched off my double pole breaker that feeds the inverter. now my meter came back on. switched the double pole breaker to inverter on, so the inverter has power but does not work because it’s on off status, meter stays on… switched the inverter to on status and now it doesn’t work again.. this is even when I still have my mains connected via the change over to my essentials load my inverter is new, not connected to any internet dongle yet and also the firmware is still old.. would this make a difference I don’t need to switch my main supply for my inverter off, as soon as switch the status of the inverter to off via the green button the side of the inverter then my meter comes back on.

July 18, 20223 yr Author Would wiring the 63amp isolator and the 63amp earth leakage like this drawing compared to my other drawing make a difference? I feel like the problem is somewhere here.

I feel like the problem is somewhere here. No it would make no difference. Both drawings are the same with respect to getting the grid power to the plug where the meter is connected.
July 20, 20223 yr Author so I changed the wiring to my second diagram just because I’m trying everything at this stage, now the meter doesn’t trip when it’s switch on but does trip when the essentials are running through the inverter, this is weird because the meter is connected on the non essentials side. sometimes it doesn’t trip when the essentials is running through the batteries and sometimes it does. It tripped last night at about 10pm. Was still tripped by 1am… this morning at 7.30am it was fine and working. I have no clue what’s going on. I have requested an update for the inverter via sunsynk website.
July 20, 20223 yr Author Can someone explain to me why I have 1.5amps of power on the grid side graph. It reduces slightly in amps when I switch of my essentials circuit breaker which is very odd because the problem is the essentials are running on the batteries so why would that make any difference to what is going through the inverter? That amperage is almost constant all the time?

July 20, 20223 yr Author @Scorp007 The ct coil is installed as per my diagram, but the arrow on the ct is facing the inverter direction. The sunsynk 8kw manual says that the ct coil must be connect on no.5&6 terminal with the voltage on no.5 which I’m assuming is the white wire, if connected with the white on 5 the the ct coil shows minus figures so I swopped the wires so the white is on 6 , as I read in the manual. The 38watt is the grid trickle because I set it for 40 watts and when I change the grid trickle that value changes accordingly. The 730 watt I assume is what my essentials are pulling, crypto miner is 700 watts and when my geyser switches on then that 730watts changes to around 4300watts as my geyser is 3600watts. But the 40 or 38watt will stay constant Edited July 20, 20223 yr by Derek Ramos

The ct coil should usually have the arrow pointing back to the grid if I remember correctly. Will have to go check mine again.

But the 40 or 38watt will stay constant Yes the manual shows arrow to the inverter. Also the manual seems correct in indicating what wire colour goes where. Not to confuse matters. The CT does not measure any current from essentials if fed from the battery. It only measures power fed back to the grid or from the grid. If connected wrongly it will show a negative reading so it seems it is connected correctly. Still not sure why the CT sees 730W which is coming from the grid but the grid reading is only 38W?

On a Sunsynk it is the opposite.

If Im running on ups only so the inverter only uses the batteries when I have load shedding then that LD value is what my load is. But if I’m running on batteries and have a grid trickle ticked at 40 watts then the LD value is on 40 or 38watts. I’m assuming if I don’t tick grid trickle and leave that value at 0 then maybe the LD value will sit at 0. Ld is what I’m allowing from the grid into my load ( essentials while using the batteries I assume. What I don’t understand is why I have 1.5amps displayed on my screen just above the ct coil Edited July 20, 20223 yr by Derek Ramos LD
July 20, 20223 yr 14 minutes ago, WannabeSolarSparky said: Here are the settings I am using... So we get back to the CT measurement. Yours shows the CT in the right position and that it draws 49W from the grid as it should be. Derek's graphic does not show the CT? In your case one can see PV is feeding your non essential load and PV is also proving the battery charging power.

Yes, feeding all essential, non-essential and battery. With the essential loads taking priority. Edited July 20, 20223 yr by WannabeSolarSparky
