I should have clarified that it won't export more than 15kW without additional AC coupled sources

He purposely overloads one leg beyond what the spec sheet says is the max. Try that same test on an EG4 18kPV or a sol-ark 15k. Both of them will be able to start TWO of those compressors simultaneously and the latter would be able to do it while also running a large central heat pump (while...

There's too bad considering that this video gets called out all the time for being completely misleading

I still don't understand why the WP units have essentially no surge ability. You'd think they could handle the 2x for 5-10 seconds or whatever that the older units did.

I think he was talking about the 15k. If so the numbers would be a bit higher for these scenarios (i.e a full 15kW (minus AC load) continuous can be exported).

I've seen a few pull through chargers but they are still in the vast minority. Hopefully they start putting in more now that the CT is out.

I wouldn't be surprised if it throttles down when charging from a generator based on the incoming voltage/frequency. I've never seen behavior like that when charging from solar or the grid though.

Who's gonna convince seplos to create a 16S kit for these? It should be about the same size as my first car.

It's a simplified spec sheet because the output is dependent on the battery voltage. At 54V it'll output ~14kW battery only from the inverter. At 52V it's down to around 13.5kW. At the typical LVP of 48V it's down to about 12.5kW.

I have never heard of anyone having problems with charging throttling (I have never seen it with mine). What are his ambient temps?

Ah, still bad but not quite THAT bad.

That's crazy. In the US we can get grade A for like $100/cell now plus $10-15/cell shipping.

Ah I thought you were taking about hybrids. My old LVX6048 behaved like you are describing. I'm not 100% sure what it would do if you overloaded it while grid was available though.

With the hybrid inverters I'm familiar with, it is always connected to the grid (unless the grid is down or outside the allowable parameters) so it doesn't need to do anything special if there's a large load.

With that usage you're probably gonna want 2 18kPVs or similar if you're fully offgrid
