    Is anyone using MIN TL XH US V3 with ATS-US?

    I have a MIN 1400TL-XH-US and an ATS-11400-US purchased from Signature Solar. The inverter refuses to supply power to the ATS. When grid disconnects, it enters standby mode with warning code 300 (no utility) or 607 (abnormal communication with off-grid box). No voltage on the backup terminals...

    This may be a stupid question

    It's a good q. I suspect the problem is that there can be arcing at normal operating current s.t. the fuse would not open the circuit.

    i need help connecting growatt batteries

    try swapping enable + and enable -. I also suspect the "DC switch" on the inverter needs to be closed

    i need help connecting growatt batteries

    Had a very productive call with Growatt Tech support today. They figured out that the RJ45 pinout Enable+ and Enable- are swapped in the manual pdf I found online vs the physical copy that came with the device.

    I have 217(02) with my MIN 11400TL-XH-US and my LG RESU10H Prime. Very much stuck here.

    Sol-Ark 15k install Schematics

    Thank ou. I found some interesting discussion on this topic in the Tesla support forum. https://teslamotorsclub.com/tmc/threads/does-tesla-ever-install-solar-powerwall-systems-using-line-side-tap-in-california-with-pg-e.235590/

    Sol-Ark 8/12/15k with Tigo TS4-A-O?

    Is it correct that a SA inverter without batteries can be stuck in rapid-shutdown during grid power outage until grid power is restored to the CCA? Except as long as PV power is available to the CCA when the grid power outage begins? E.g. 1. Daytime grid outage. PV power continues 2. Night...

    Sol-Ark 15k install Schematics

    Thank you, that's really helpful. I didn't realize I could take a detour out of the enclosure between the meter base and the breakers. I think I'll do something similar. Any issues/tips for making changes to the utility-sealed side of the meter/main?

    Sol-Ark 15k install Schematics

    Is this right? (E) Meter base -> (N) 200A Fused Disconnect -> (N) Sol-Ark -> (E) Panel main breaker/disconnect In that case, did you connect 2" conduit from the Meter/main out to the disconnect, and 2" conduit from the Sol-Ark to the Meter/main?

    Sol-Ark 15k grid-tie hybrid design in CA

    Would appreciate some critical feedback before I submit this to PGE. A few questions that come to mind: Is the Sol-Ark 15k oversized for 13.6kW? I like the 200A load and whole house backup. Sol-Ark 12k might work but it's gonna be harder with my meter/main which is obsolete and only has 2...

    Sol-Ark 15k install Schematics

    Just talked to Sol-Ark engineering who agree that the conductors between the tap and the grid should be rated for 400A in diagram 7 of the manual. Alternatively the 200A fuse could be placed between the tap and the meter.

    Sol-Ark 15k install Schematics

    Assuming the service conductors (and meter) weren't over-sized, aren't they unprotected from over-current in this design? 300A = 100A (tap) + 200A (MSP). Was the Line-Side tap approved for inverters that only feed-back but never draw from the grid? Is it still valid for hybrid inverters like...

    PGE Interconnect: How to Limit Export?

    You're right about the LVX6048 but not the LVX6048WP which supports grid export https://diysolarforum.com/threads/new-all-in-one-mpp-lvx6048wp-ul-certified.23505/post-281226 Can I change my inverter next year after getting Permission to Operate from PGE and remain grandfathered under NEM 2.0?

    PGE Interconnect: How to Limit Export?

    Well CEC lists the Sol-Ark as "Inverter with PCS functionality". So I suppose the answer would be Power Control System. I am tempted to save $ and use a MPP Solar LVX6048WP instead of the Sol-Ark 15k. But it's not in the list of approved inverters despite being UL 1741 SA since March 2022...
