Unboxing of Deye 16K Hybrid Inverter

Yeah but if you moved from CA or IL to a place like NH you'd save thousands of dollars a year by not paying income or sales tax. And you'd still get federal solar credit.
Woulda coulda shoulda. Better do some research on the FTC not sure the Deye qualifies for that either but I’m not a tax guy. However if I’m not mistaken there are a complete set of guidelines and requirements to qualify for that also. But obviously that doesn’t bother you either
 
Nice inverter congrats

I just found your picture with it inside a cabinet don't do that it will run hot, I have one 5KW and I had to put a fan in the top to force more air thru the dissipater because DC was always over 60 celcius / 140 F

I guess that is what really sets apart the 2;

Deye is best for offgrid/grid assisted with no feedback/selling.
Sol-Ark is best for On-Grid/GridTied with feedback.

At the end of the day it's all about what the end user is planning. If they are off-grid, I see no reason to not get a Deye other than support and warranty?

I think the new FTC for 2022-20xx requirement is very relax for residential.
The system has to be installed and the electricity generated supplies the resident.
That's what my CPA told me.

All inverters should meet these two conditions.
 
My best advice for anyone purchasing solar equipment here in the USA is to select your equipment from the California approved list unless you are totally off grid. If you do so you will be assured that you will qualify for any rebates or incentives. If it’s not on the list you may not qualify. That’s the long and the short of it.

Not only in USA but everywhere here in Portugal to have a certified installation you need to have an inverter registered in state list and also panel’s structure, can’t imagine if a person got hit by a flying panel.

I don’t know the law regarding batteries but if there isn’t one we need it, they store a lot of energy that can be very dangerous.
 
Finally Amazon delivered the 3/8 tinned copper lugs yesterday. Remove the 16K out of the box onto the dolly, my test platform.

Here's the parameters of the initial Deye 16K test platform

1. No Solar input are configured.
2. Grid US Split-phase L1~120V L2~120V L1~L2=240V
3. No Autotransformer was installed for the LOAD output.
4. Battery bank is simulated using a Variable Voltage Power Supply (Charger) 1V~60V and Current 1A~30A, support CV (constant voltage) CC (constant current). The Power supply were set to 54.4V simulating a fully charge 100% SOC battery bank. And is the primary source of power for the 16K. The battery configuration is configured to BATT V (battery voltage), only in this mode will the Inverter enter into full operational state with NORMAL LED in Solid Green. The 16K will start Inverting, the LOAD will now show voltage on both L1 & L2 and measuring the post will show live voltage. Tried using Batt % and Inverter will never enter into operation status, as the Inverter built in Shunt was unable to measured amperage capacity of the Power supply and thus display 0% SOC.​

the inverter is superheavy 140 lbs., it's not easy to move it into the dolly single handed.

Ahhh..got my platform setup. I'm using my 120V*30A=3,600W variable power supply to simulate battery bank.

One go crimping with a hydraulic crimper.

Shrink wrap tube with backing glue does the job.

Grounding and wiring up the GRID input.

Could not find the right socket, luckily Harbor Freight Tools is still open and grab a SAE & Metric socket for $6.99. Good enough for the job.

Configured the Power Supply to CV 54.36V (constant voltage)

16K powered by DC Power Supply 54.4V, simulating 100% SOC of battery bank. Start up successfully by turn on DC Breaker and Side on button. The Power button now have a Blue LED light, pretty neat.

Unlike the 8K Power switch, the 16K comes with a nice Blue LED to let you know the On/Off status. The PV Switch now have a safe lock mechanism to prevent accidental turning On/Off.

Changing GRID to 120V/240V Split-phase and see if it works ?

Switching to 60HZ US Grid type.

Deye 16K configuration. Inverter operational status, NORMAL LED is GREEN and start inverting, as such there's VAC on the LOAD terminals. Take note of the "Inverter" and "Load" menu, L1~120V L2~120V that's Split-phase 60HZ without a Autotransformer !!

Inverter is powered by Simulated Battery bank using a Variable DC Power Supply with CV. Normal LED is Solid Green and status is ON. entering into Inverting state with live Voltage delivered to the LOAD output.

Inverter self consuming about 53.4V*1.81A=98W, great power efficiency for such a big inverter.

1670783019135.png
Inverting with L1~120V and L2~120V

1670783059665.png
LOAD output L1~120V L2~120V
