All things Sunsynk (Deye, Inge, etc...)

A friend had a Deye inverter system installed at their house. They have some cheapo LED ceiling light units in some of the rooms in the house.

Soon as load shedding hits, these ceiling light units has a glow, no other lights have anything. Why would this happen?
Soon as load shedding ends and municipal supply returns the glow is off.

Earth neutral bond wasn’t done correctly.

Get them to come back out and do it properly.

Other lights likely aren’t earthed and/or aren’t LED which requires very low power to illuminate.

I will let them know. Installer has no issue fixing issues and doing changes till the customer is happy. Thank you.

This is a safety concern more than anything else.

Basically there is no earth while being Load Shed.

It's floating earth. The earth-neutral bonding relay isn't installed or isn't installed properly, so you will notice about 50v between earth and live or neutral which causes the LED to glow. One of those Ellies surge arrestors plugs also give clues about this earth issue. If the LED on E is lit then there's no earth. It's a safety issue if you have faulty electricals in an appliance... Earth leakage won't trip.

My installer also didn't fit the relay so I DIYd it. Got this:

Earth Neutral Bridge Box Single Phase 25A

Earth Neutral Bridge Box Single Phase 25A

You can save alot by just getting the relay instead of the whole box. Mine fits nicely behind the panel of the inverter in the left corner. Very easy to install. I'll see if I can get the relay part number.

Out of interest, on the Ellies plugs, will the Earth light up only when running on battery - or will it also light up when grid connected?

It should remain the same, irrespective of whether grid is present or not (loadshedding). In other words, both the live and the neatral lights should remain illuminated and earth ligh off.

If the earth light is off when no grid is present the there is a faulty earth.

Hello guys,

I have a 5KW Sunsynk inverter. I have a question regarding the CT Coil. What issues may I see if the direction of the CT coil is toward the grid instead of toward the inverter?

I had solar installed recently and set up my inverter so that excess solar is exported to the non essential loads but not to the grid. My installer says that the CT coil is pointing to the grid but the inverter behavior seems to be more or less as expected, except for one thing - every now and then, I notice that for a second or two, the inverter shows that a little is being exported to the grid. Is this normal behavior or a result of the CT coil not pointing to the inverter or something else? Other than this, it seems fine as when I switch on my geyser or stove, then it draws the power from solar.

You need to have a little trickle to the grid otherwise it causes some prepaid meters to trip into a tampering state.

Thats normal yes, you can see all the sunsynk guys in the "show your solar..." thread have some grid feedback.
 
Hi Guys
I have only had my system for a few months now and looking for some guidance on the solar production others are getting from their panels.
- 5KW SunSynk, 7 x 550W Panels in a single string on one MPPT
- Tiled Roof at ~18 Deg almost facing ~NNW, Gauteng
The peak solar I am seeing on clear sky day is ~3300W (load is demanding more) vs theoretical max is 3850W. With cloud edge it peaks higher sometimes on cloudy days.
Is this the normal expected yield do I have losses somewhere?
Interested to hear what others consistently get vs their total installed capacity.
Cheers

Seems about right - with a NNW facing roof you miss out on some capacity at peak (11-1pm). The heat also reduces efficiency of the panels

He probably means his peak which would be mid-afternoon. I agree, the heat is probably the factor, but would be interesting to compare others peak vs theoretical peak.
 
Good day

I have a 5KW Deye inverter no panels. What are the settings to get optimal efficiency from the battery? The settings are still at default since the installation.

what are they set to and what (if any) issues are you experiencing with the defaults?

If you have no panels I'd have the batteries set to charge to 100% and run down to max during LS. What batteries have you got?

Thanks Speedster. I have a 5.12 Shoto. I was just wondering if there were any settings to maximise output. I will leave settings as is.

Thans Mzezman. I do not have any issues persay. I do however experience at times, that there is a F34 error and battery beeps when we are not on load shedding. Not sure if it does go over the 5KW mark this happens? I reset and it goes back to normal operation. Just curious to know why when it is on Grid power
