    EG4 18k backfeeding 400v to mains

    CT problem could cause isues with grid feed and such, but the problem we are all seeing is the system components should not produce more than around 250 or so Vac, that would be ~350v peak, a far cry from 400+. CT should control voltage insofar as to control the flow back to the grid. First...

    I am disconnecting my solar panel strings the next 36 - 48 hours.

    Interesting. Must have been a static buildup, one would assume cat-2/3 or UTP of some description. Coax or outdoor STP with a ground should have eliminated that, of course four times as expensive. Static buildup was likely due to the plastic sheaths rubbing and twisting and the cable...

    Complete guide for 48V using EG4 18k

    Victron ESS i"Energy Storage Systems" s a concept with PDF's and papers that use the various Victron components, Like a Quattro, which requires a separate auto-transformer for split-phase operation. None of their products seem ideal for the North American market. Their power cable 'manglement'...

    can 6000xp inverters thermal throttle

    Your PV curve looks normal and smooth. This would seem to indicate you are maxing out your PV. To that end looking at the panels: So if you have sets of 7 in parallel 9.33+9.33 = 18.6A The 6000XP: Maxes out at 17A. Any time you have a parallel situation You could be clipping an amp or...

    I'd be stunned if a solar event caused a problem of any kind with a solar system. Not quite the same as low voltage device connected to something with a ton of external wire.

    can 6000xp inverters thermal throttle

    Thatsalottapanels. I count 49. You have 4 MPPT's you might get better performance if you get your VOC up closer to 500, but 250 should be OK for actual.. I don't have the MPPT specs but if your voltage is too low you could clip if your panels provide more AMPS than the MPPT can use, it's a...

    can 6000xp inverters thermal throttle

    You say potato . . . Blue line is PV I have about 19KW of panels, line peaks at 15KW. Drops off when batteries hit 100%. There is another 12% loss between the production and output that means I get to use around 13200 of the 15000 to charge batteries and stuff. so around 70% of my rated PV...

    House burned down

    Depends on the something. Buildings with reflective glass melting cars, yea, ... Don't put a leaky oil can on the shelf above your swimming pool tablets. . .

    AIO High Frequency Invertors. Warning They don't Have An Iron Core Copper Wound Output Transformer.

    Weeel, not a great ROI. . . If energy prices double over the next 10 years maybe you'll be applauding your foresight ;).

    Complete guide for 48V using EG4 18k

    Aluminum Blue Eurotrash :ROFLMAO: 18k(pv for Tim) all the way! Victron needs to come up with a decent split phase AIO to stay relevant. Over time reliability improves and costs fall with lower component counts and better integration. We are already seeing this in the current batch of AIO...

    AIO High Frequency Invertors. Warning They don't Have An Iron Core Copper Wound Output Transformer.

    Make sure your batteries scale up as needed. I found the 30KW stack struggled a little under high demand with a pair of 18kpv's I'd want 2 5K batteries for each inverter. YMMV.

    I think some go north of 12 yards, though 8-10 or so is the standard. Max gross weight for a normal transfer truck is 80,000 lbs! There are also the 4 hopper trucks that mix on site than can deliver smaller loads without killing you price wise.

    Hammer? pffft. Smooth rock, and a dime to turn the screws.
