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

[RonSwanson]

It is doing the same thing today. It is frustrating as it is throttling solar generation to use stored power and supplement from the grid.

Any other ideas anyone?

Post pics of ALL the settings, plus a video of the behaviour.

Is there anyone who runs multiple aircons (for heating or cooling) at the same time for a few hours? What is the consumption like?

Depends on the BTU and temperature. Our 18,000 unit in the lounge uses around 1.3 kW. The 12,000 BTU in the room uses around 1 kW. NB these are inverter models so the draw is constant. Non-inverter models are less efficient...

Cool. I have been doing some reading and they say some inverter type aircons can idle at 500W when it has reached its temperature.

My bedrooms do this. Once they reach temperature they idle between 400w and 600w for a 12000 BTU unit.

Alright. I should be sorted once I increase my battery bank. I have been in this house (new build) for almost a year now and I just need to prioritize a few things (fireplace vs aircons + battery bank).

24000 BTU inverter AC set to 20^C

and then heating at 23^C

That is good. What aircon is this? I plan on getting Daikin ones towards the end of the year.

In fairness, that current draw would be relative to the temperature outside, and how hard the AC is working. It is pretty tricky with inverter ACs.
I have a 12000BTU inverter aircon (Samsung Windfree) that fluctuates between 400 and 1500W.

My 24 000 BTU inverter aircon on the lounge idles at 1kw.

I switched it on at 3pm and off at about 17:30

True, I unfortunately don't have data from last summer for the lounge temp. Only added a sensor there this year.

This was today;



If I look at last summer, December, when it was ~29^C outside, the consumption is higher but once it's at temp I get the same 300W draw. The spike at the end is probably because we lowered the temperature to make the place cooler before the timer turned it off for the night or because of loadshedding - I can't remember, it's too long ago :



For the past week I've been using the AC everyday, it's a really nice feeling to be able to run it for "free".

I have preinverter aircons ie old school. The 18 000 btu are klapping 2500w start up and then settle on about 2000w and then the 9000btu klaps about 1500w max

have a look on the rating plate .aircons use different gasses some are R134 some are R22 and still others use blended gasses ,the newer gasses run at a higher pressure ,cool quicker and run at a lower amp .on the rating plate it may give LRC ,that will be start up current the other rating will be running current at a full charge weight ,if too high your aircon tech can change your current consumption by changing the fill ,some charge by current some by weight .

Trying to figure out the minimum number of panels that can go on a 5kw Deye inverter. Datasheet says 150v.

The 545w Canadian solar are 40v. So am I correct in saying I need 4 as a minimum?

Daikin FTW.

Have 12000 and 24000 BTU (inverter types).
Quiet, super efficient and proven over decades to outlast most other brands.

There's a reason you see so many of them in the Middle East, SE Asia and other warm regions. Toyota of AC brands.

Try get the R32 gas type if budget allows.

Yes

Ouch. That would drain my battery in no time

Thanks. I see ACDirect has a few of them. I'll check a few installers around my area if I can have a packaged deal.

Seems the impact of higher temps + low VOC on my panels shaves around 1000Watts in peak solar production even in crystal clear weather. Efficiency is around 80% today at peak

Might be I can get higher peak efficiency in winter times, but dissapointed at the drop in peak solar due to higher temps in Durbs today, and it's not even proper summer yet.

Might need to rethink these panels and their strings
