Hi guys,

Quick question, Do the DEYE inverters require an external AVS (Auto Voltage stabilizer) to be connected?

also, what makes the DEYE superior to the likes of Growatt?

thanks

for connection to grid? nope and neither if its stand alone...

yes for connection to grid, using as a backup system currently.

As someone who changed from Growatt to Deye, my reason for the change, off grid inverter vs. Hybrid. My battery did not communicate properly with the growatt, and the bms froze all settings. Battery works well with the Deye and settings are fully customisable. 

I also find better flexibility on the Deye for the day to operation as pertains to grid vs battery vs PV power. I find it better for my needs than the SUB and SBU settings. 

I wouldnt say the Deye is superior. Its different, and better suited for what I needed.

I have seen the insides of both. The Deye is easily worth the price difference. (IMHO)

Ah.. could well be. I have never seen the insides.. and even if I had, I wouldnt know if components were quality or not. Good to know really. I am happy I made the call to switch when I did.

Generally not, depending on the load you wish to supply, like general household items.

While connected to the grid, the output of the inverter will follow the input Voltage from the grid, and as we all know Eskom / Municipal Voltage does fluctuate.

During load-shedding or grid failure, the inverter will maintain a solid nonfluctuating Voltage on the UPS (Essential Load) output.

On the grid settings, the input Voltage and Frequency, upper and lower settings can be adjusted, so if either upper or lower settings are out of range, the inverter will switch off grid and onto UPS mode. But you really don't want to set your limits too tightly. 👍

Do you have special equipment which needs a particular Voltage?

i had an external AVS for the grid supply to the inverter, reason for this is the power surges that happen when eskom power is restored. this protects the inverter from damage by these surges.

so i was wondering when changing inverters now, if the deye would still require this external AVS to protect it from surges.

 

can the deye inverter combine solar and grid power to supply the load? 

instead of solar/battery combination.

Yes it can
