Unboxing of Deye 16K Hybrid Inverter

[misterbubbacat]

Since the inverter has internal AFCI/GFCI, why are you using an AFCI/GFCI breaker? Are you disabling the internal AFCI/GFCI?

Where do we start here? I've clearly explained the rationale for the decision. The 16K is EU 230V single phase, with the L=115V N=115V are HOT just like our 240V; WITHOUT A NEUTRAL for Split-phase . In my application, I will be using an external Neutral from the Autotransformer. The 16K firmware CANNOT operate in Split-phase and shutdown with F08 error. If there is an ARC fault error or Ground fault error, the 16K WILL NOT provide any protection as this happens outsides of its operating perimeter and hence I need a AFCI/GFCI combo breaker for NEC compliance.

do you have the link of the manual page 5 of 51?

The 16K has a slightly large rated output of 69.6A*115V(L) + 69.6a*115V(N) = 8004w*2 = 16,000w at a lower cost ?

continuous AC power with batteries on 120v loads theres no info in the manual.

continuous AC power with grid your not using the inverter you are just using the power utility transformer because you are bypassing the inverter. your max load will be your 200a main breaker multiplied by the voltage 120v = 24,000w

Yes, it listed in the datasheet page 43/48 in the PDF; I've highlighted in Yellow, UPS=Batteries ?

that is balanced loads or 240v loads not unbalanced loads.

that is balanced loads or 240v loads not unbalanced loads.

Remember, the 16K is a Single-phase. L=115V N=115V Total 230V. Think of it as like our 240V appliance with AC L1=120V L2=120V Total 240V. The unbalanced load is with Split-phase only L1-N L2-N which is not an issue in Single-phase of either the Sol-Ark 15K or Deye 16K. If all the 230V/240V load used up the MAX capacity of both Inverters will throw a "F18 AC over current fault of hardware" error will raise Red Alarm and exit Normal operation mode.

i just write in google solark 15k datasheet you get directed to this page

https://www.sol-ark.com/wp-content/uploads/2022/04/15K_Specs_4_27_22-1.pdf

That is not the one on there Website under the 15K model.
It seems that is a Pre Release Link from April and is incorrectly worded.

Here is the official Link

the solark dont manage inbalance in loads i have installed a few solarks 15k and it does not manage well loads in one leg if you go over 4.5kw it will send overload fault to fix this you have 2 options change the layout of your loads... in the kitchen get the outlet with the microwave to one phase and the outlet with the fridge and coffee machine to the other phase or get an autotransformer that automatically balance the loads.

Have you updated the Firmware and what version are you using?
All Sol-Ark Inverters are initially released with Firmware that is very conservative in it's settings. That is why David Poz did not want to update the Firmware from the original version before during his tests.
If a Sol-Ark 12K can handle 4.5K of unbalanced load then a 15K will most certainly handle it.

And BTW yes, a house should have all the Loads balanced. My Toaster and Microwave are right next to each other but My outlets on the Kitchen counter use different Phases for each plug outlet box. Electricians will normally do this for safety reasons. Solar Installers are supposed to double check and make sure that the 120V loads are balanced on commonly used together 120V items.

everyone, just get a 240v deye 16k and save $5k usd then get a growatt 11.5kw autotransformer and get 11.5kw per leg instead of 4.5kw with the solark and throw the saved $5k into 20kw lifepo4 batteries.

Whats the point if the Inverter cannot be hooked up to the Grid or to a Generator? Your losing all of the main features of the Sol-Ark.
It just sounds like you could save more money and buy a 12K Growatt Inverter and at least have a Warranty and Support.

I guess you pretty much answer your own question. Unfortunately, the High frequency inverter is know to be limited in the handling of imbalance split-phase load with all its other pros; this is not just a Deye or Sol-Ark issue. Trying to balance the 120V circuit in the main breaker panel seems like a logical steps prior to the installation of a Autotransformer. On a single 8K, I was able to pull up to slightly more combined 4,000w each leg totaling 8,000w without triggering the F18 error.

If there is an ARC fault error or Ground fault error, the 16K WILL NOT provide any protection as this happens outsides of its operating perimeter and hence I need a AFCI/GFCI combo breaker for NEC compliance.

How is that happening outside of its operating perimeter? The inverter still only puts out single phase. There will be no balance problem with the inverter output because it’s only supplying single phase. I’d assume the inverters internal AFCI/GFCI would still give its protection Since the inverter is still only supplying single phase.

16K LOAD L,N ----> Autotransformer L1,N,L2 ---> LOAD Panel ----> Branch circuit AFCI/GFCI breaker.

I've explained in details in previous post and will not respond to more questions on this topic, maybe another use could help explain.

For those who are interested, Deye 16KW is about $2800-2900 from Alibaba sellers

listen feller.. I’m a certified/licensed electrician… I completely understand that the inverter is single phase L/N and that an Autotransformer supplies neutral L1/N/L2. If your simply referring to AFCI/GFCI breakers in a load panel then yes almost all of the breakers in a load panel now have to utilize those breakers. I just purchased $2000 worth of them and it sucks..
My question is why do you have to have AFCI/GFCI breakers after the inverter if the inverter already protects it’s output with AFCI/GFCI? If your to good to respond then just say I’m to good to respond, which is basically what you did..

Does it have something to do with having the Autotransformer. Like the Autotransformer makes it so the inverters internal AFCI/GFCI isn’t sufficient? If so how? Or anyone else not to good to respond to my “dumb” questions?

Savings are a little less than 3K. But for those not off grid, will it pass inspection?

Below are Usage report for the month of 12/2022 with low usage, 09/2022 and 08/2022 of the LOAD panel being feed by 2*8K with a total of 16KW, the equivalent of a Deye 16K or Sol-Ark 15K. Notice the L1=Usage_A and L2=Usage_B in the report is not totally balanced, and have not had an L1&L2 out of balance shut down. The system is running with Grid AC being off with just Solar and LFP battery bank.
