    Same, done and filed. The solar tax credit was not memorable.

    Schneider Conext SW4048 for grid-tie system

    If you don't have batteries, what's the point of a battery inverter/charger like the SW 4048? It doesn't integrate a charge controller.

    Sell it back to them. It doesn't seem that unreasonable.

    Limitation to AC coupling with EG4 18K, help required...

    Agreed, this is the standard way to do it, before Sol Arc put the AC coupling function on the AC2 input.

    How to AC Couple & Frequency Shift a SolarEdge SE5000H-US

    Is the grid connected when this happens? What specific equipment do you have, other than the power wall? If you have a powerwall, what does the installer say about this behavior? Seems like they're warranty should be involved?

    Victron Orion Voltage Drop

    Too bad, that would have made fault finding easier. Set the volt meter to min/max mode, hook it up, and then start the Orion. It might take a few tries to locate the voltage drop, but reset and move the meter leads until you locate it. Locating the exact source of the voltage drop will be...

    Victron Orion Voltage Drop

    Instead of guessing or making educated assumptions, why not test to find the voltage drop? Can you adjust the charge current on the non-isolated battery chargers? If so, adjust the current down to the point that on will continuously run. Then start measuring for voltage drop. Your problem could...

    NEC compliance for Backfed breaker

    The loads in panel don't factor into the calculations. It is just main breaker + backfeed breaker <= bus bar rating +20% So, if you want to increase the backfeed breaker, your only options are to downsize the main or increase the rating on the bus bar

    TIGO Reset

    It could be the SolArk was trying to pull a very small amount of energy out of the 3.5 ish volts (and almost no current) that the Tigos will let through when RSD is active. What Tigo components do you have?

    Adding storage to my Enphase system

    I'm pretty sure the rest of the country calls this phenomenon "spring" 🤣 Otherwise, sounds like those panels are working great!

    TIGO Reset

    I miss read this line, I thought the power cycle did nothing, my mistake.

    Can't find the answer - best panel for the money. Roof Mount

    Most all panels are 18-22% efficient. Meaning that higher wattage panels are just physically larger. If you have limited roof space, you may need to do like I did and map it out with different size panels. It could be that the larger 550 watt panels don't fit in the space available or you can...

    Can't find the answer - best panel for the money. Roof Mount

    There's no single answer to your question. There is no "best" If you are looking for new panels, I agree with 740GLE, contact your local CED Greentec to see what they have on hand. They don't put their pricing online, but it is reasonable, for the panels I purchased they were about the same...

    TIGO Reset

    Sounds like an open circuit somewhere in the PV. If the circuit was intact, the Tigos should put out 0.6 volts each, so 0.6 x number of panels in series should be your measured voltage if it was an issue with the RSD stuff. I guess you could remove one PV wire from the inverter to measure open...
