Hi fellow SS users. I am just starting a DIY install and wanted to ask the best cable to use for extending the CT coil to a max of 20m?

From what I know shielded twisted pair using the same pair is the key to success. So was thinking cat6 would do the job?

CAT5e also works fine - mine is extended 20m using CAT5e

Great, thanks. Ill give this a bash and enable "priority load"

Yes export is intentional.

There are a few things, like pool pump and microwave, on non-essentials but the rest is on essential load.

I think Priority load should help your situation. Look at HunterNW's graph on the previous page in this link, the solar is being used to charge batteries while powering the load from the grid. Only once the batteries are full does it run the load off solar if there is enough. And then you are wasting the rest of the day's production. With Priority load enabled the solar will immediately be used to power the loads and only the excess will be used to charge batteries, which will then only be full later in the day. This way you will make much more use of your solar power.

This is how mine is configured, I also use "non essential".

I don't export that's why "inverter power limiter" is set to 0w so you can set yours to 5000w or something.

I also have loadshedding and keep my SOC\v higher as well as having the grid top up the battery. So uncheck the grid boxes and change the SOC.

How are you exporting solar?

 

[B-1]

How are you exporting solar?

You need to tick the solar export to feed the non essentials. Then set "inverter power limiter" to limit the export past the CT coil to 0w.

These screens are not the most logical.

Sunsynk and Deye need to hire a proper UI and UX designer - those inverter screens are terrible

Instead they seem to create video after video to explain something that could be intuitive.

Its probably intuituive for them but not for everyday users. Even the lingo used - Zero export (when you are actually exporting to non-essentials)

Deye actually have quite a good video.

Purchasing power problem

Hello, I have an installation with 2 deye 3p hybrid inverters. But i have a purchasing power come to grid constantly day and night. I don't understand where the problem comes from. This continuous power is about 10 to 15% of the power of the load (see attached graph). Can anyone help me to solve ...

We, too have joined the cool kids club. Still trying to figure out what works for us. They initially installed the wrong inverter and after they came to replace it the app now doesn't work and we have to wait three weeks to have the gateway reset

Are you sure you want to use the grid between 1 and 5pm to charge your batteries? Considering you'll likely have a lot of PV available - seems a waste

Goodluck in understanding your usage trends and finding out what works best for you. What are the other components of your install?

The idea is that we drain the battery at night and that it should charge up during the day using solar. From 23:00 the house is on "idle" and minimum power is used anyway right up to about 8:00. We will see, might change it again.

Right now we have a 8kw inverter, with one 5kw battery and 6 x 450w panels. We opted for a bigger inverter and less panels to start with, and will add more panels and batteries as we have the funds.

By lunchtime you might have the battery fully charged anyways - see how it goes for a few days.

Sheesh, I am so confused now.

If I want my excess PV (ie. after batteries are full and all essentials are powered) to be used to power non-essentials, then I would tick "Zero Export"

Question is, what are the other settings you would need to select for this.

Checking the Sunsynk manual - I see this:






So to me, it looks like one should only select "Zero Export"?

Yes.
If you ever get confused, check the realtime flowchart, the picture will show the CT coil. If you tick "limit to loads" the CT coil will disappear.

It helps to realise "zero" is a verb and not a noun in this instance. You are telling the inverter where to zero the export - either at load, or at the CT.

This would be easier:

As as user i would like to:
1 - export to non-essential loads but not the Grid
2 - export to non-essential loads AND the Grid. If i export to the grid i want to set the amount of power exported

I find the Deye wording to be more intuitive

 

[TheJman]

Thanks so much all! Really appreciate it!! Sheesh their descriptions are not great - I gotta pick up their lingo so I stop getting so confused.

So just to confirm, if I want excess Solar to be used to power non-essentials, then I tick "Zero Export" and "Solar Export". I then set the Inverter Power Limter to 0. Thereby ensuring I'm not feeding back into the grid?

Question:

1. If I set the above, will it only draw from the excess PV to power the non-essentials, or will it also draw from the battery?
2. What would ticking "Zero Export" and "Limit To Load Only" result in?
3. What would ticking only "Zero Export" result in?

Sorry for all the questions.. real noob here with this and trying to learn.

Thanks all!
