    Working with a local solar contractor?

    The electrical and plumbing inspector in mine require the licensed contractor pull the permit. The plumbing inspector is a special kind of asshole. Even a simple code question is met with "Your licensed plumber will know the answer to that question." I I get it. Mostly I just want to...

    Working with a local solar contractor?

    I am considering putting in a grid-tie system in my house, and would like to do as much work as possible. My wife will not let me on the roof, so that is out. The local muni also is CRAZY strict (can't even call to ask them questions if not a lic. electrician), so I will need to work with a...

    Whats a good 48v bms??

    The JBD BMS's are very popular https://overkillsolar.com/product/bms-100a-16s-lifepo4/ Andy from Off-Grid garage seem to like this unit: https://www.aliexpress.com/item/1005003104573871.html

    Hybrid Inverter sizing advice

    It looks like if you have a 0deg phase angle, that's what you are going to get on the output too. That would be no-bueno. This is from the LV5048 (and 6048) manual:

    I dunno, maybe that would work. I'll watch the video. Thanks!

    Hybrid Inverter sizing advice

    Not sure what the trick was you mention. My issue is that I would like to use my 120V generator to charge the batteries from time to time (using the all-in-on), which I cannot do it seems unless I go with 2 units. That would also allow for a split phase setup, but it has some disadvantages...

    Hybrid Inverter sizing advice

    The product lines are a complete mess in my opinion. At least they are in the pure off-grid applications. Perhaps my use case is not common, but it seems like every unit (or combination of units) is lacking in some way. The LVX6048 seems to get me pretty close, I just wish I had a 240V generator.

    I don't think that is the case. My understanding is that many of the 6Ks are low frequency inverters and can handle inductive loads better.

    Looking for a unicorn off-grid inverter?

    I am trying to find a split phase (or 240V+transformer) off-grid inverter in the 5-6KW range, that accepts a 120V AC input for charging. Preferably that can accept > 250VDC of solar. So far, no luck. The MPP LVX6048 and Growatt 5000 from MPP requires 240V input. The Growatt 6K split phase...

    Generator for mpp solar lvx 6048?

    Can you confirm I cannot use a 120v generator with the LVX6048? Did not realize that and would be a deal breaker

    NEC 710 / Split Phase

    Nevermind, I get it. BRANCH circuits. Duh.

    NEC 710 / Split Phase

    I was trying to determine if I can get away with a non-UL listed AIO unit for an off-grid property in Michigan, and was reading through the NEC, when I found this: 710.15(C) Single 120-Volt Supply. Stand-alone systems shall be permitted to supply 120 volts to single-phase, 3-wire, 120/240-volt...

    Good review on supplier.

    FYI, tested the first cell (EVE 304).... 314 AH!!! I don't have the patience to test the rest. Will likely just top balance and build the battery and see what the total capacity is.

    I wish there were a better selection at the higher seer ratings. Only finding a handful of options.
