I mean for example the Chint smart meter has a version that takes input from a CT coil instead of having to be mounted inline to measure current. Can the Eastron SDM230 do that? I would go for Chint but the Chint store on Ali Express insists that its meters are not compatible with Deye...

Can the Eastron SDM230 work with a CT coil instead of being inline?

Is this from your own firsthand experience? Because Deye support was trying to talk me into purchasing a Chint-3P meter as being the only compatible one with my hardware... But they're expensive compared to the single phase ones...

Oh well moot question since I have just realized that the compatible smart meters (Chint and Eastron) can work with a CT coil instead of being inline. Now next question: my Deye inverter is a SG01 version, which has a "meter con" port on the board. However when in "zero export to CT" work mode...

Has anyone managed to get their Deye inverter to accept data from one of the RS485 CT clamps available on the market? The compatible inline smart meters are not a good option for me due to wire size and also because a non-invasive solution is much preferable. Analog CT clamps are not an option...

So now I am stumped. I checked the reading at the meter last night (it's an old-style disk mechanical meter with 3.6Kh) by timing one revolution and calculating that the pull from the grid at the meter is only 17W (12 minutes and 42 seconds for one revolution). However, near the inverter, I have...

50W would be vaguely acceptable but 300+!? And unaccounted for... If I turn off the grid breaker near the inverter, the meter stops. It's definitely the inverter doing that, there does not seem to be a "leak" upstream. I will take a reading over several hours tonight.

I'll drop a message to SA support see what comes out.

60.0

Solarman shows 2 decimal places for the value I am interested in (grid frequency). See attached screenshot. Not sure why this does not make it to SA. Edit: SA is connected to the inverter via RS485

I have a Deye 8kW inverter. Since I have no net metering, I set it up to use the battery power at night. However, I noticed that the inverter continuously pulls 1.3-1.6A from the grid (300 to 370W) at night AND this power does not seem to be accounted for in the metrics. Any clue? See attached...

I have established communication with SA's MQTT server via Mosquitto but all the values I am getting are limited to one decimal place. Is there any way to adjust that?

Can anyone comment on linking SolarAssistant to Home Assistant, vs going with just Home Assistant with the Deye plugin?

That was it! Completely missed it, thank you!

Is there a way to access / set all the inverter settings with SA? I have a Deye hybrid inverter and I see only the work mode and TOU settings, none of the battery / grid settings...

Deye 8kW Hybrid Inverter. Yes it has TOU but that's not the point. We have a crappy grid here with wild voltage and frequency fluctuations which destroys appliances. If the inverter remains connected to the grid all the time and the inverter is programmed for normal acceptable voltage and...

Hello, Is it possible to run the Deye as an offgrid inverter and only switch on the grid when needed to charge the batteries? I see in the battery setup that there is a "grid signal" feature, which could potentially be used to control an external "normally open" relay or contactor to connect...

Is deye.com even a legit website of Deye? Their official website is deyeinverter.com and their official alibaba page is deyeinverter.en.alibaba.com and these pages make no mention of these batteries. There is also a deyeess.com website. Looks dodgy too.

On Amazon it shows this... Go figure... It's a jungle out there, how is anyone supposed to find their way through that mess??

I live in Asia so most of the stuff we get is Chinese. Many DC MCB say "non polarized" yet they show + and - symbols on the schematic so what gives!? Example here: https://s.lazada.com.ph/s.5YZbR

Although it could be argued that the directional breaker on the good battery would prevent its discharge into the shorted one... Non polarized dc breakers seem hard to come by.

True and very good point. Are class T fuses non-polarized?

Yes I agree but a catastrophic discharge current (short circuit on the load side) seems a lot more likely than a catastrophic charge current (other than maybe from lightning, which the PV circuit should be protected against)?

I can wire it that way and put a test load on it and measure that the currents are approximately equal with an ampmeter.

It is polarized, as per the schematic that is printed on it. Which is why I want to wire it that way.

Assuming same length and gauge wire and decent crimps, it should be close imo?

So I have this 63A dual pole DC breaker and I want to make it a 126A breaker to protect the positive side only. Can I wire it like this to achieve the intended effect? (wires coming from + pole of the battery)

Ow and from the Sol-Ark manual - also a Deye rebrand: So there is definitely an absorption stage and it stops at 0.02C - not user-definable.

hmmm reading the Sunsynk manual, which is a Deye rebrand I think, it seems there is an absorption stage but it seems the cutoff (current or time) cannot be user-defined? From the Sunsynk manual:

Can't find a boost setting either for the Deye or MPP Solar, and at a glance also not Luxpower (TBC). So does it mean that these three just switch off altogether right after the bulk stage without holding the absorption voltage at all?

Reviewing the document below, specifically the note about the accumulation / saturation / absorption stage on page 5, I notice that most popular all-in-one inverters (Deye / Sol-Ark, MPP Solar, LuxPower...) do not seem to have a setting for the accumulation stage cutoff. They however all have a...

Hello, I have a 100Ah 2p8s pack made of EVE 50Ah cells I recovered from a commercial rack pack. The bus bars appear to be welded or glued to the cells' terminals so no way to reconfigure the cells. I performed a top balance by charging each pair of cells to 3.65V with a bench PS (while they are...

PV array voltage range for both 8kW and 11kW units is 90 to 450. Typically around 350 Voc string would be ideal for efficiency.

Please be so kind to specify which better alternatives you are referring to
