From what I've read the Deye generator "load" function can be used for a dump load - eg dumping excess power into hot water rather than exporting to the grid.

I knew about summer in Aussieland when it's winter in Yorup but I never thought about that solarpanels should face north down under!

get an open dtu to track the data from there. Open source and you can do an awull lot. Reverse engineering of the hoymiles protocoll and getting rid of hoymiles cloud. You can also add more targets like displays or pv solar tracking cloud.

The gen load might only be a reporting error on Solar Assistant. Had the same happen on my Deye when connecting micro inverters. Disconnecting SA from the Deye in the config section, waiting a few seconds and then connecting it again.

Hi can post a video on how setup solar assistant to the Deye inverter? I'm struggling.

If ac coupling not gona work with gen port you can allways connect it on grid side like enphase. Only drawback is in offgrid scenario deye will not provide island network for them.

@HomeGrownAlchemy 5 ай бұрын

The ac couple start point may be the SOC of the battery. Lowering that may restart the ac couple on the grid port as well as the ac couple on gen port and the dc coupled. The gen port can be used as a switching port. If you connect a load to the gen port and set the parameters such as battery socket reached 90% then turn on the n supply gen port with power activating the load you have connected to it. Not really about to be done with the micro, but as you said, the Debye have so many features.

Sounds plausible. Experimentation required.

With the knowledge there is a micro inverter installed, it can also kind of throttle the power of the inverter by altering the frequency of the simulated grid on that port. The inverter would throttle on a certain frequency and would even entirely switch off at a certain threshold.

@HomeGrownAlchemy 5 ай бұрын

@@markusresch9889 in an off grid situation it can alter frequency of the microgrid it is forming on the backup and gen port, but in a grid tied situation, it cannot alter the frequency as it cannot fight the grid frequency. I have not tested this personally, but as all the ac circuits/bus are tied together when the inverter is grid tied, it is limited in that respect.

@markusresch9889 5 ай бұрын

@@HomeGrownAlchemy without deeper knowledge about it: the generator port of that hybrid inverter should be a totally separate micro grid with out any direct connection to the real grid, right? Because it's only used to add additional power to the battery charger. If that port would be in any way connected to the real world grid, you would have to meet a ton of regulations for any generator you'd attach to that port.

@@markusresch9889 No, The gen port is physically connected to the Grid through a relay that switches when grid fails! So the DEYE can only provides a microgrid to the mircoinverter when the normal grid is down! It can NOT produce a Microgrid while connected to MAINS GRID!!

@Akash-ry6du 3 ай бұрын

AC couple start and stop SOC function is quite useful for off grid installation, if you have connected any string inverter or micro inverter back to the gen port and battery soc reaches the off value % then deye inverter will raise the frequency of the gen port to trip the string or microinverter. For on grid when the soc of the battery reaches the on value then the deye inverter will close the relay on the gen port and allow the ac current of on-grid inverter or micro inverter to feed-in. and if you have enabled MI export to grid off then it will trip when it reaches the off SOC %. Let me know if it makes sense or not. cheers!

Does the micro inverter work out of the box or do you need the app to set it up

To talk with Hoymiles micros, you need their DTU (Data Transfer Unit), they use some sort of custom Sub-1G networking for comms, gives them more range and penetration.

some newer hoymiles microinverter have a build in DTU, they only need wifi to work. had one installed half a year ago, works like a charm.

Hello buddy, this was an energetic video. Please don't do videos only because you want to rant; do videos, also, when things work. You never know what Easter eggs you may inadvertently drop for people who may have been scouring the web for answers. For instance, I have a DC-coupled Sunsynk hybrid system but I have used both MPPTs on a North-East//South-West split PV (strip the badge from Sunsynk and you'll find that it is the long lost twin of Deye - they are exactly the same 🙂) and I need to expand by system using a plug and play microinverter but hearing you on this video has given me inspiration. What I am kindly asking is to know exactly how you connected the wiring off the Hoymiles into the GEN port of your DEYE. Did you have to use a gateway? Did you have to use an AC isolator? Or did you just connect it straight to the GEN port. What kind of wiring did you use 8 or 10AWG. Can you draw a map of exactly how your Hoymiles is wired into your Deye?

@britto89 5 ай бұрын

In your travels Dave you found what the input max of that Gen Port is? You've put 800w into it but do you know what the max is if you had more panels?

@dama054 5 ай бұрын

The max is half the inverter out put so if a 5kw unit then the max is 2.5kw

I think you will not get more than 600W, because the microinverter gets too hot.

@G88gleplex 5 ай бұрын

AC coupled on Grid = setting the Gen input to Micro-inverters (it does the same). It keeps the CT coil at 0 watts so nothing is exported. (TBH it's does not care where in the system the microinverters are connected) The % are very important.... If you have a power cut (AKA Grid failure) the Gen port will continue to supply power to the microinverters and they will continue to produce power in to the system and power the house and charge the batteries - GREAT. If the Batteries are at 100% and the house need no power the generated electric has to go somewhere. The 100% means when the battery is at this it level will shift the output frequency to 52Hz and the micro-inverters should shutdown. It will switch back on at 95%. (EDIT: I think this video explains it better - kzbin.info/www/bejne/pYjRo3mHprF9bZY)

@eDoc2020 4 ай бұрын

I believe frequency shifting is only needed when microinverters are on the emergency load output. When using the "generator" port as microinverter input I believe it disconnects the power when 100% charged and reconnects when down to 95%.

Dont call Deye monitoring is junk just because you used the Solarman Smart app. Deye Cloud and Solarman Business apps are much better than Solarman Smart. I bought Solar Assistant license and never ended up using it because I like the Solarman Business app much better. UI is better than Solar Assistant as well Only advantage with Solar Assistant is that it provides instant updates but you lose out on firmware upgrades, some remote configuration options and warranty support from Deye. You might think that firmware upgrades arent necessary for devices like these but Deye added many features (e.g. MPPT multi point scanning) with the firmware upgrades. They release new upgrades like once every 2 months.

@EEVblog2 5 ай бұрын

I tried their cloud thing, couldn't get it working, and it looked stupid. I don't want to touch firmware updates, and have been advised by several Deye owners never to update working firmware. If it ain't broken, don't fix it.
