Hi everyone, I am looking for Microinverters to suit 140 cell panels namely, Trina Honey 370 and Trina Tall Max 450.
I would like to use DEYE Microinverters but I dont think they are compatible due to panel cell requirements.
Any advice or recommendations would be appreciated.

Regards,

Max
 
There's nothing special about the VOC on those panels. I'm sure if you checked your specs and the specs on the difference Enphase micro inverters you'd find at least one compatible with your panels.

But, for the second question. The Deye inverter has Solar inputs, these are meant for a string of panels. Not for an input from a micro inverters.

You might be able to AC couple the micro inverters to the Deye hybrid, but it sounds like you're still planning and planning to spend extra at this point as the Deye can take the PV input without purchasing micro inverters.
Plus, there have been plenty of posts recently about difficulty AC coupling to Enphase (specifically) micro inverters.
 
Thanks for the reply.
I didn't think they would be compatible.
I am going to AC couple the Deye string inverter and use it on the gen port for additional supply instead of Microinverters as they arnt available in Australia according to Deye and the String Inverter works out much cheaper.

AC coupling is not that difficult as long as the GT inverter is UL1741SA compliant

That is how SolArk and Deye do it so if the frequency Watt from the grid forming inverte (Deye or SolArk) cannot modulate the GT micros fast enough, the grid forming hybrid inverter can just disconnect the micros by opening the relay on that port, instead of risking and over voltage event. It is a balancing act which the grid forming hybrid inverter has to have somewhere to send the GT micro power when a load drops and if there is not enough capacity in the battery pack it has to be curtailed rapidly.

I have a Deye Sun2000 G3 (EU) microinverter with 4 MPPT inputs. Each input is connected to a single 144 cell (half cut 72 cell) 455w panel. No problems.
This microinverter has a maximum VOC of 60v.
Take a look:

They also have a US version if you need.
 
Hi thanks for your info.
As Deye microinverters arnt available in Aust I have gone with the Deye String Inverter 3.6 kw.
Much better value for money with heaps more capacity.
 
Yes I only need it to boost additional power in the late afternoon. Additional panels facing west. It is coupled with a Deye 5kw Hybrid.
My main panels for Hybrid are facing North and South. I need additional boost in the afternoon in winter time.
I only have around 1kw of panels facing west on the string inverter which can be increased in the future as I have an additional 8 panels. (12 Total).
I can just extend it as I have the additional room. Its mainly just an experiment to check the results.

Hi Max,
With the micro inverter from BENY is it working too. We have Single-In and from Q3 2023 the Quad-In. If you need any information, let me know.
 
Hi, I have decided to go with a grid tie inverter on the Gen port as a secondary input to boost power in late afternoon. It works out much cheaper than microinverters ang grater capacity and I don't really need individual panel monitoring.
