    MPP Solar LV6548 split phase supply side tap details

    Yes. Through a knife switch. It is one or the other. It is impossible for both at the same time.

    MPP Solar LV6548 split phase supply side tap details

    I have my 2 LV6548 plugged into a NEMA 14-50 outlet. I have the outlet turned on at the loads panel. At the loads panel, I turn off the GRID "line"(main circuit breaker). I am thus isolated from the grid. My plan however is to run my system like this, as soon as I can convince an electrician...

    MPP-SOLAR LV6548

    Yesterday I had a day where I fully charged the battery and saw the LV6548s "turn off" the panels. It happened again today. This time at 1:15 in the afternoon. Now I know the feeling of wasted energy. I could have had my car plugged in at that time, but it was charged enough also! I would...

    NIPPLE slip

    A - Solder it in place. Probably will work perfectly fine. B - Find a professional welder. Probably the best option if you can find an experienced aluminum welder. My guess is that these were friction welded in the first place.

    No flir camera. The thermal gun has shown warm spots, but that is just the case, so not much value.

    MPP LV6548

    I had a huge hassle on my LV5048's getting the 6 to fit, and removing some strands was the only way to make it go. But the LV5048 shown 10awg was all it needed. I had zero issues at all putting my 6 AWG into the 6548. I have some Wire Ferrules and a 60-ton crimper that might work to make the 4...

    MPP LV6548

    I think I may have found a contributing factor for the shutdown. I am using 6 AWG AC wires. Max Current has shown to be 37 amps for 6 AWG. I am going to get get some 4 AWG right away. If 4.11 mm fits, I think 5.2mm will be able to get squished into the connector. pages 6 and 45 of the manual...

    Ummm, you have them both, go through each menu and have a look. 🤣 I got a reply from MPP-Solar support, they wanted the S/Ns and mentioned "NTC cables". I guess the NTC cable is the temp sensor.

    Does UL-1741 standard apply to off-grid inverters

    UL 1741 SA is the new safety test standard certifying products which meet the rigorous requirements needed to ensure safe and reliable operation in support of grid modernization efforts. Grid support or "smart inverter" functionality will be required by Hawaii and California beginning September...

    MPP LV6548 AC Wiring Question

    Did you use 4 AWG for the A/C in-out? I have 6 AWG on mine, only because that is what I used on what I had prior. I want to do some cleaning up and just want to make sure the 4 AWG will actually fit.

    40 foot long Iron Flow battery

    Their premise is wrong already. "$350 per kilowatt-hour." for lithium ion. I have a year old lithium-ion, made new, for $94 per kilowatt-hour. If this really is the case in "utility" scale applications at $350. I can see how much overhead there is, and how much money is flowing that is not...

    Actually... You can run ONE LV6548 in 120V configuration without any battery at all. I forgot that the LV6548 does have a "battery-less" operation function. https://www.mppsolar.com/v3/splitphase-lv6548/ Batteryless operation (single unit mode only)

    No, the battery has to be 48v configuration.

    Home Assistant - Solar Monitoring and Management

    I was putting the IP into the wrong spot. Doh! Thanks for the assistance. I got pretty overloaded when it discovered my house and all the crap I have. 😂 My printer and it's ink levels, something call onhub, and about 30 binary sensors. Yikes. I even got my grid-tied solar edge connected...

    Home Assistant - Solar Monitoring and Management

    I'm making some progress.... Ok, how do I "addin" Solar-Assistant now? Solar-Assistant is Enabled. (I would think with "discovery" enabled, HA would say "look what I found", but not yet).

    I'm still in the "make HA work" phase. I put HA on an SD card then put it in a Pi400. Now all I have is the HA command prompt. Well apparently HA isn't going to work at all via WIFI. Plug the ethernet cable in, and magic starts.

    What about an 8s 4p 24V configuration?

    You are making the battery. Do you want to know what 32 cells are doing or 8 cells are doing? It is your $ you are spending. If new grade A cells, I'd go 4P8S, resulting in one "battery pack". If used old cells, I'd go 8S times 4. New cells made practically at the same time will have very...

    Here is a diagram of how I want to charge my 2 -- 12 v 150 ah with a DCC50S 12V 50A DC-DC On-Board Battery Charger with MPPT.

    That looks pretty much like what page 7 of the owner's manual indicates. https://www.renogy.com/content/RBC3050D1S-G1/RBC3050D1S-Manual.pdf Consider using a DC circuit breaker for the panel and the battery, not the ANL. You can switch the DC circuit breakers off when you want to move things...

    What about an 8s 4p 24V configuration?

    You confusion is about to get worse. Anytime you connect any "battery" to another "battery", you just created one new battery. A typical 12V car battery is 6 2v cells. You only see the two battery posts on the outside of the big plastic cover. On the inside of that big plastic cover is 6...

    What about an 8s 4p 24V configuration?

    I have 4, 48V LiFePO4 batteries in parallel. Working fine for 2 years now. I don't see any limit at all other than your wallet and space to how many batteries you can parallel any battery, regardless of voltage.

    Grounding Rod Necessary

    Good point... Human 10,000 ohms, 1000 ohms if wet. 25ft of 6awg copper = 0.0031665 ohms Human has more than 3 million times the resistance than the copper ground rod. 300,000 times more if wet.

    Grounding Rod Necessary

    Can you touch the panel while you are on the ground? If you feel some juice flow through you, then you need to bond/earth the array. The most confusing term used is grounding. You are a lot more resistant to the flow of energy than a grounding rod and a copper grounding wire. If there is a...

    I updated my LV5048 once. I think it was a standalone firmware program outside of watch power.

    Do I have too many solar panels?

    You need 8 cells to make a 24V setup. 6 will just make you angry all the time.

    Threaded bolts for rack made of unistrut and tapped into shuttle bus ribs?

    I used the bolt to attach some unistrut on the underside also for more "mounting" options for other things. What it looks like on the top side: https://diysolarforum.com/attachments/20210224_154655-jpg.38461/

    Threaded bolts for rack made of unistrut and tapped into shuttle bus ribs?

    I did it on my cargo trailer build, they are holding quite fine. I have driven with them at 60 mph with zero issues. I used bolts and fender washers on the inside to spread the squish. I don't think I would chance it by tapping the hole and using the tapped hole for the thread.

    I asked DMI to test them out with a heavy load on his newest video. Does the Mach-E have a 11 kW onboard charger? I can adjust the EVSE on the fly through wifi. The 1st spike was 20 minutes when the LV6548's shut down. The mid plateau is 24 amps DC. The 2nd spike was just a test to see it...
