[RE-wrenches] GTBB inverters without batteries

[Kirk Herander, VSE]

Storedge 7.6kw inverter functions fine without batteries. I've had one working for a year like this, waiting for the customer to pull the trigger on LG Chem RESU set.

Hey Wrenches,

I should have been more specific in my question.

I'm well aware of the advantages of true-off grid inverters and the expansion routes of Sol-Arks or Sunny Islands as well as their price point!  Serious surge, serious battery expansion capability, stacking etc.  However that all comes with a price . . .

What I'm needing here is a simple 7.6 KW grid-tie inverter with minimal (15KWH) backup upgrade route.  No big expectations on the backup or surge - just minimal backup at an affordable price.

So in that world - I know the PWRcell works well without batteries - but I have less experience with StorEdge or SkyBox.  And the PWRcell is a new beast perhaps since Pika was acquired?  I know Generac has been upgrading . . .
Any experience with any of these in grid-tie mode with no batteries?

Thanks,

Jeff

Sol-ark will function w/o batteries. Pretty straightforward installation with no need for a separate charge controller.

Hey Esteemed colleagues.

I'm curious which GTBB inverters folks are installing when the customer can't afford batteries right away.

How do StorEdges, Skyboxes, PWRCells perform in purely grid-tied mode with no battery and any advantages - disadvantages of various options folks want to point out or considerations for the upgrade path of each?

Thanks,

Jeff
