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...
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...
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
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...
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-...
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 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...
