are battery required
we have a GS8048 connected to grid and solar, no battery's as of the moment. Can I power up sell solar without batteries?

Re: are battery required
No. Outback inverters (except Skybox) are battery based inverters, meaning battery is needed to make them operational, including sell function.
By the way, how is the inverter connected to solar? There is no direct connection from mentioned inverter type to solar.

Re: are battery required
No, so I don't need batteries? Using flex 80 with 4k in panels. Or no don't start with out batteries.
Thanks
Thanks

Re: are battery required
Perhaps filling out your equipment profile will shed some light on what you have..
(And you have to have batteries. 48 volts worth.)

Re: are battery required
vt,
I was answering your question "can I power up sell solar without batteries?"
The answer is NO. YOU NEED batteries.
On your FM80, it needs a battery too.

Re: are battery required
That's what I always thought. A solar guy told me it didn't have to have battery. Thanks for clearing it

Re: are battery required
Wonder if solar guy hooked up the FM 80’s without the batteries?

Re: are battery required
In fairness to the "solar guy", his knowledge of inverters maybe limited to grid-tie inverters, or as Outback call it now, Grid Dependent inverters which do not require batteries to function, but useless during grid outage. Examples - Sunny Boy, SolarEdge, SMA, microinverters.

Personally, I would never buy panels with integrated micro inverters, for just that reason..

Re: are battery required
My friend with a Tesla system (2 Powerwalls and a Backup Gateway) uses Enphase microinverters on his panels and apparently can continue to charge his Powerwall from the panels (and of course run house loads) in a grid outage. Maybe the limitation isn't as severe as it used to be...

Re: are battery required
Sounds likely. The systems I've looked at were directly grid tied, with no battery/powerwall on them.provo wrote: ↑Thu Jan 21, 2021 10:12 amMy friend with a Tesla system (2 Powerwalls and a Backup Gateway) uses Enphase microinverters on his panels and apparently can continue to charge his Powerwall from the panels (and of course run house loads) in a grid outage.

Lose the grid, -poof- no more solar.
Not familiar with what is in the Powerwall, (inverter type, etc.) but I'd be willing to bet the Enphase 'sees' the Powerwall output as 'grid' and continues to sync to it.
