  • Post in thread: Max VOC - How strict?

    Well it looks like there’s a way to make a voltage limiter, regardless it’s way out of my wheelhouse. Yes it obvious just size the panels correctly. But so many nice panels are approaching 50ocv and some charge controllers really respond better and have more day hours with running in the upper...
  • Post in thread: Compress or not, flexible busbar or not

    I won’t get into what’s better. Spring are $11 but I wouldn’t use it on more than 8 cells so you set up 3/16” less than max deflection so WHEN the cells grow you are still safe but had plenty of push to start with. The pusher should be made from two 3/4 ply glued together for a 1-1/2” approx...
  • Post in thread: Sol-Ark 15K + Generator

    I don’t believe any Generac “home” series (stationary/standby) are inverter type. To guarantee good frequency regulation, pure sine wave and fuel economy, nothing beats an inverter generator. The DuroMax 9000 and the one shown below are dual dual fuel and can be rigged to start/stop with dry...

  • Post in thread: Information Overload - Where do I start?:)

    It was a wonderful boat and the cat and I had made thousands of memories. When he passed away it was the last reason to not have the boat, fuel was the other reason. I knew that as long as I owned it the boat would go out every weekend which means $$. It was fully functional unlike most other...
  • Post in thread: So... Set me straight on a few things related to battery C ratings and BMS capacity... Please!

    I think you’re going to have to them fabricated. I say “them” because two or more will be easier to lower into its final location then run jumpers across as needed but make sure if in series the the jumper’s resistance equals the resistance of a buss used. You can have the boxes hard anodized as...
  • Post in thread: MPP LV65 Failing Over to Utility When Battery Fully Charged

    What does your Solar Assistant show for inverter one ? If you are using SA to change states and it is not showing inverter one as the unit you have as master there could be some issues.
  • Post in thread: Multiplus ii UL listed and non UL listed for split-face.

    I just clicked on the first four Victron sellers and all had the full 30 day Amazon guarantee(Amazon support). Amazon takes this very very seriously that sellers adhere to this. Even if you purchase something by mistake you can return it, just don’t do this too often as you can get bumped/black...

    Or go Freddy Krueger on it. Some shorted layers and let the air in.
  • Post in thread: zinc vs stainless vs galvanized vs aluminum hardware.

    Keep in mind that most stainless fasteners have much less strength than a common zinc plated bolt. Using stainless can sometimes be self defeating because you have greatly distanced the metal nobility difference and one will loose. There are several grades of stainless sometimes the weakest in...
  • Post in thread: What’s your daily SOC range?

    Looks like I’m replacing my battery meter(Hall effect type) It’s been getting worse. It’s only reasonably accurate if it gets to a full state of charge within a couple days and when it gets hot the voltage is incorrect. It has lots of nice info, pretty colors and…it’s junk. Got another cheapie...
  • Post in thread: EG4 6500 EX Inverter setup issues.

    I highly doubt you’ll have a problem even if you started them at exactly the same time. I’m running 23 year old 3 Ton as we speak, no problem. Don’t even think about the coffee maker, microwave and AC at the same time. We can do the dryer and AC, but why push it. All you need to do is turn one...
  • Post in thread: LV6548 turns off after 13 minutes

    Do you have it in SBU mode?
  • Post in thread: Why is this wire so hot?

    lol. Yup, that works.
  • Post in thread: Active balancer, make it smart!?

    Back when you asked “which is fastest” I didn’t know you were already an expert.
  • Post in thread: Jk bms balancing issues

    What does the wire resistance say? Screen shot?
  • Post in thread: Cheap Emergency Dual-fuel Generator for EG4 6000XP Recommendation?

    Thou I like the inverter generator, there is great merit to using a chargerverter. With a chargeverter you don’t have to worry about limiting your pass through current or energy management beyond normal inverter functions. If you use a generator directly to the inverter, you have to be sure you...
  • Post in thread: Battery rack improvements.

    I like compression too, but Eve looks like they’re trying to detail a torture device.
  • Post in thread: Sol-Ark 15K Rejected by PG&E in California

    The biggest problem with Sol-ark is they probably didn’t know that the string of numbers they got from Pigs Goats & Elephants is an off shore account that needs funding.
  • Post in thread: Solar Assistant croaked?

    http://10.0.0.5. The one in the instructions page that work day one. Just a white page appears and the progress bar bottom left just starts and hangs indefinitely

    God how I hate auto correct.
  • Post in thread: Solar Assistant integration of two batteries (two JK BMS)

    About to pull my hair out and atomize the SA. I’ve rebooted and still can’t see the two JKs. I can see one inverter and one JK but only two USB’s at a time. Using a power hub + the exact items as needed shown on the SA website. The only thing that works is the emulated bms. If doesn’t give me...
  • Post in thread: LV6548 AC input settings

    Hey it does work for 8 places. I’ll probably only use four closest to the wall but two for now. Have to use spacer washers if I don’t put lugs between the buss and post outrigger.

  • Post in thread: Solar Assistant not switching to SUB at set battery SOC

    Yes you can see both, but SA instructs one inverter. If it’s talking to the wrong one nothing may happen.
  • Post in thread: New Solar Assistant beta 2024-04-05 and stable 2024-01-23 software released

    Did you try a different cable or adapter? I’m running these;
  • Post in thread: Absolute easiest whole house pv+battery support. Is this possible?

    Agreed, I like it because it has a lot of the stuff built in you’d otherwise have to have in the periphery. Clean and a money saver. I just don’t know if they have without any question solved 100% zero export.
  • Post in thread: We did a load test on the new EG4 6000EX inverter

    Yeah, I know better than to try to start my compressor at high pressure. It’ll trip my breaker till I’ve used it down below 60%. To not know this means not much time around them. My inverters won’t care, plenty of punch.
  • Post in thread: My jk bms just exploded after i enabled charge, and i dont know why. See pictures. i need help

    I think you need to watch Andy’s “Off grid garage” early JK bms episodes.
  • Post in thread: Who's is bigger?

    Well you got me beat. Obviously, you don’t have cats in that room. Mine are not allowed in the garage either. One hairball is called Chewbacca or Chewy for short, guess why? But I’ve got sticky traps to catch anything that chews out there.
  • Post in thread: Almost seems like its better NOT to have inverter communication?

    I’m quite satisfied with my open loop system. I don’t believe I’d be able to do this without the active balancers that I’ve always had in one configuration or another. The time at bulk, absorb, full or whatever you want to call it is not configurable in my AIO, it has its own algorithm which...
  • Post in thread: electrocution on metal roof

    It depends how the racking system is designed and code in your area. It may have integrated washers or clamps that bite the panel frames and tie it in. But many don’t so you need the special lugs. The lugs are special because they not only make a good connection but they also have much less...
  • Post in thread: 2023-08-16 Solar Assistant update. But take note.

    Lost inverter temperature data on Votronic inverter MPP LV6548. If this is important to you (ME!) don’t update! Edit see below
  • Post in thread: Autonomous SOC control Solar Assistant

    Yup, it did ?
  • Post in thread: So why buy an additional balancer if active balancing is part of bms? This turned into waste of time

    It works for some and not for others. It’s dependent upon your pattern of use. If you use some sort of controller to switch on the balancer above 3.42VPC , it’s pretty much guaranteed to work for most applications and you don’t have to wonder if it works for you or if your pattern changes. It’s...
  • Post in thread: Alert when grid fails

    My personal problem is I’m an old machinist and past competitive shooter. Can’t hear my phone half the time and bothering the house because I’ve got the tv so loud. Wearing protective hearing/coms at work so the last thing I want in my skull when I get home is more junk lol. My power company...
  • Post in thread: Looking for light weight racking material to build my own racking system.

    When I got my unistrut was mid Covid and I had to scan HD & L every day because it was always empty. I came up a few lengths short so I had to get some from Lowe’s. The electrical contractor supply houses were 3x the price because they knew it. HD was the lowest price because they had a pricing...
  • Post in thread: Series string shading summed up in 4 pictures

    I’ve got running data on my system. I may bite the bullet and see what’s what. Just wondering out loud, I wonder if the diode could be eliminated for even better efficiency with an optimizer?
  • Post in thread: JK BMS cell UVP ‐ Prevents charging via AIO inverter

    That’s pretty early for that amount of delta at 3.2 volts average. My usual call is to harp about a loose buss terminal connection. Since you have had a good top balance and you noticed an oddity, I don’t believe in coincidence. This may be the rare bad cell🙁 that bad luck dropped in your lap.
  • Post in thread: No indication that inverter is getting power from panels

    You have dissimilar panels in series? And what is the open circuit rating range of the inverter?
  • Post in thread: DALY BMS %$&@

    I foresee in your future, a Daly doorstop and JK bms install. Can’t say you didn’t try.
  • Post in thread: Bus bar contact resistance

    I just got done doing a new fuses blocks in a boat. started one tub. The stuff sure got soft from a week ago when it was cooler.

    Love to know what the seller has to say about about that!
  • Post in thread: Emporia Vue Inaccurate Values

    Could it be that the outside unit has some sort of compressor heater to insure that it’s ready for heating mode.
  • Post in thread: Battery rack improvements.

    True, waiting is a risk. However if you have spent millions on unique anode or cathode treatments, without proper backing and planning, submitting a patent is simply an open supermarket for thieves. Many have gone broke defending their patents.
  • Post in thread: LV6548 Battery Charging

    That MPP just isn’t happy until it gets to around 125 volts. You can wake it up by putting all six in series for 225 volts. Yes I know it says 90 starting but…… Edit! Stop! Over voltage! My bad! The maximum you can put in series is 5 panels.
  • Post in thread: Battery Disconnect Switch OR Resistor?

    When the inverter takes a break, ya gotta remove the loads immediately before it restarts. Is wife proofing even possible? I highly recommend one of these to keep an eye on your load. You can configure a contact to operate a warning device at a selected current level https://a.co/d/jfMJWwx
