Unbalanced 3 Phase Inverter

Featured Replies

Does anyone have a 3 Phase inverter that can output unbalanced loads that exceed the TOTAL kW divided by 3, per phase?

e.g. Take a 12kW inverter. L1,L2 and L3 Should output 4kW max each. 3 x 4kW = 12kW. If the load on L1 pulls 5kW then (i assume) a normal 3 phase inverter get's overloaded.

But this DEYE claims it can output 6kW max from L1, provided the rest of the lines are below the total 12kW when added together.

meaning: L1 is at 2kW out of the total 4kW that it can output. L2 is at 3kW, of the 4kW it has. Then L3 can be up to 6kW. Without overloading the inverter.

Yes it is correct that 1 phase can be at 6kW and the other 2 then share the other 6kW left.

Wow... That's so smart... I wonder if Sunsynk does or will ever do that...

No reason why the similar Sunsynk would not operate the very same way. 

Other posts have indicated it will for sure.

But currently? I don't think so

Which areas are different? 

I asked the installer if one phase gets above 4kw, he said it will shut down, so that is why I thought the Deye was better  But clearly he and I were wrong. I just downloaded the manual for the 12kW and it states:

 

"These amazing three-phase inverters have a unique feature. They can operate and balance the load, which means you can have 20% connected to one phase, 20% to another, and 60% to the third phase, and it still gives perfect phase rotation. No other inverter in their class can offer this feature. "

 

Ironically the last statement is also wrong as the Deye can.

So I'll stick with sunsynk.

I'm sure it is meant no other design as all the different names that are identical to the Deye design can do it.
