Subject: Issue with Zero Export to CT - Seeking Assistance

Hello everyone,

I recently installed an 8kW Deye inverter, equipped with 8 x 550W solar panels, and a 10.6kW lithium battery from SA Lithium. Ideally, I'd like to divert any excess solar energy to power non-essential appliances when the battery is fully charged. To achieve this, I followed the instructions to install a CT (Current Transformer) on the grid line and selected the "Zero Export to CT" option.

Now, I'm experiencing a positive power reading on the external CT, and my Load Consumption reading takes both essential and non-essential loads into account. However, during load shedding events, the non-essential appliances switch off, and the load consumption reading (house icon) drops to 0kW, even though my essentials continue to be powered by the battery.

Does anyone have a solution to this issue? Your assistance would be greatly appreciated.

Thank you.

That is not an issue, it's working exactly as it is meant to. Non-essentials are off during load shedding.

On the deye app the house icon is the non-essentials, the ups is essentials.
 
Anyone with the Sunsynk 5.32kwh batteries notice a clicking sound repeatedly come from the battery when it's full?
Usually notice this when there battery is fully charged, LiBMS screen shows charge amps as 0A. And then every few seconds the battery makes a clicking sound like a switch/relay. Generally when solar is still available. Is this normal?

My House Icon shows 0W when the Zero Export to CT is on and the UPS just increases :(

During load shedding, non essentials will always be off. They are not on the UPS side but the non-essentials side. The only time the inverter will power them is when Eskom is present and there is excess capacity as configured on the inverter.

If you want them to be powered during load shedding, put them on the essentials / ups side. Or have a changeover switch that allows you to switch them between non-essentials and UPS.
 
Thank you I think I’ve managed to grasp it , I’ve also understood now the Home Load (non-essentials) feeds from the battery when the Time Settings have the battery less than 100% and I don’t want this Need to do some tinkering in Home Assistant to remote control the inverter and switch between Zero Export to CT in the day to Zero Export to Lod at night

I still don't understand why the aux is not utilised more. In most installations the house is either split between the ups port and non essential loads before the inverter.

The aux port allows you to have more control over loads that would normally be on non essential and can be powered during load shedding.

Try looking at using the aux output for the non essential loads. No need to tinker with HA as you can set it based on battery SOC

I've looked into the AUX port but I've read a lot that's it very unreliable, unless I'm only reading people complain about it :X3:

How old are those complaints?

I had issues 3 years ago when I installed my 8kw sunsynk. There were some updates after but by then I moved all my loads to the ups. I haven't looked at using it again as I've got other plans for the aux port as an input so it's currently not being used.

Between last month and 2 years, it's no worries though , just set up the system this week so I'll continue playing around, might just try add the geyser for now to the AUX have monitor the behavior , ideally looking at getting a heat pump and moving it to essentials.

Much appreciated :)

No you can do it keep is non essential and you Don't need to have a changeover switch can still keep them on non essential but have them powered during Load shedding to a point, Its not really explained really well in the manual but as long as you have it split already.
not sure the sunsynk equivalent(but it can do it ) but on deye under gen port usage activate smart load output

this is my setting
the 100w is use solar for these as long as PV gen is over 100w
below the micro inverter input the off (55% on mine) basically if my batteries are over 55% and power goes my non essentials are still on , if below it goes off - also seems to work in conjunction with TOU settings so say if its below 55% and power goes non essentials go off but if pv charges the batteries over 55% and i go to the next section in the TOU non essentials come on

Really interesting, thank you! Although I’m guessing your Non-Essentials load is connected to the gen port?

You're referring to aux/gen, not non-essentials I think.

You're conflating non-essentials with aux/gen port. You can't power non-essentials (grid port) during loadshedding, no matter what you do with the settings. You can however power aux/gen port connections during loadshedding.

Yes sorry connect what ever you have as non essential load items to the Gen port and switch on Smart Load Output
 
Yeah, not sure I like it but will give somem time, they could have at least fixed some bugs like the incorrect generation purpose figures...

Can the smart people here please explain how I'm being dumb.

On Sunday I had a load of 6KW and battery at 35% (the minimum level I allow during that timeslot). PV was generating 4KW and 2KW coming from Municipal supply.

I then set the battery minimum to 30% assuming I would get 4KW from PV and 2KW from battery. However this was not the behaviour. Battery was being discharged at 5KW and PV throttled to 1KW.

Have I messed up settings somewhere?

My two Sunsynk batteriess are making the same clicking sound. Asked two of my friends with the same batteries and they report the same clicking sound.

Thanks. I guess it is normal then, but a little strange.
To give more detail, I have 2x5.32kwh Sunsynk batteries, and the master makes the clicking sound. They are both connected directly to the battery disconnector, with equal length cable (according to installer). And installer used the Sunsynk connectors and added (crimped?) cabling (so not the Sunsynk battery pack cables).
Batteries seem to be performing perfectly fine though, about 2 months in now.
