I will research luxpower 6k or srne10k. the only reason I would go delta ultra is because its super easy and its plugged and play. Im a complete noob and rather have something that is very easy to setup.
Safety in numbers from picking an inverter the forum is familiar comes from having P2P support as well as improved probability of issues with the platform having been detected already.
Sure, setup will always be easier with something with a solar generator pedigree. That’s one month out of a 10 year inverter lifespan and 20 year system lifespan.
At some point you may have working battery stack but need a new inverter. If EcoFlow is gone at that point you need to solve how to get life out of your batteries, in that case it is beneficial to have safety in numbers OR use a battery that had a clear path to using with a replacement from another company.
You need to verify whether you want UL9540 ESS certification, if so then you cannot use any of these systems. California is solidly in the UL9540 era wrt building code.
Other things one ought to be concerned with on Delta Pro Ultra are how good it’s support for Rapid Shutdown and arc fault detection are. That is tricky in some platforms because those are often designed for worldwide use but these two requirements are North American. Both are required, with arc fault being impossible for mere mortals to retrofit while RSD retrofit is not bad
