Would any of them throw audibles or visuals for MPPT error as a general setting or error condition?

Really? Could it be that simple? I OVER thought it? That's awesome!

And look ma no hands!

I could use the gen start up delay dry contacts from the transfer switch to delay switching over PV to the second hybrid inverter so I don't get the jitter jog issue

I like it! Was thinking about SSRs, these are very close...

Very cool, thanks!

Trying to design at component compatibility level system that is grid tied- sell power after the second hybrid inverter charges my batteries, but if an extended outage I wanted to island with a transfer switch and switch PV over to the second hybrid off grid inverter...

Trying to figure a way to not buy a SA 15K and keep my project at $1 @ W.

OK, sounds like I need to find out somehow then if the two inverters I have my eye on will ac couple...

(without buying 2 switches...) and no way for both inverters to be fed PV

That's the concise info I appreciate, Thanks!

Still trying to "design" a 2 inverter system where I could switch the PV from one inverter to another manually.

I'm wondering how switch ratings work. If I send higher DC voltage but lower amps for the switch is this acceptable? I'm wanting to send 300vdc at 12A through a switch rated at 48vdc and 300A...

OK how about this...grid tie inverter (Growatt 6kW Grid-Tie Inverter | MIN 6000TL-X, $750) to auto transfer switch (Generac, $450 used) with 100amp LC with a EG4 6000xp connected to the ATS generator input side with my 48v batteries connected to the EG4, and solar to the Growatt. Grid goes down-...

Fair enough! Thanks

I'm actually surprise that the only offering is the Sol-Ark 15k that does everything, grid buy back, MPPT, 240v split, auto transfer switch, non-proprietary battery back-up, etc. I'm in town so complete off grid is not desirable. I'd like ToU and potentially solar boost EV level 2 charger in the...

Thanks @BentlyJ, looking at the EG4 8KEXP-240V, but Will P sure wasn't impressed. I wonder if it has improved, or if you have something else to suggest in that price point...

I'm pretty sure DC conductors has to be metal clad (EMT or MC) for code compliance...

6-8K hybrid grid buy back inverter with non-proprietary DIY 48v battery backup @ 20kWh daily usage (x3days) with 4800-5100W of total solar divided in 2 arrays of 6 panels @ approx. 300Voc each. As you can see I have an educated understanding of my usage and basic design, however I hit a wall...
