    The downside to commodity cells...

    ...is you never know what you're going to get. Ordered from Amy and received about 7 weeks later. In January I tested these 9 Eve 280Ah cells. I ordered a spare in case there was an issue with one of them, so I didn't have to wait for a replacement. I left them fully charged and they sat...

    KiteX Wind Catcher - portable wind turbine

    Not an endorsement, but this looks very interesting. Of note is the claimed 200W production at 12mph. This is achieved by having a 4.0m diameter rotor with blades only half-span to tip. https://kitex.tech/wind-catcher/ Video of setup on the main page. Claim 15 minutes. I doubt the durability...

    New Victron Multiplus-II 12/3000/120-50 designed specifically for RVs with 30A/50A input flexibility available MARCH 2021

    Just heard from a friend. Victron just had an educational session, and introduced the subject product. Key features: 12V inverter/charger (120A charging) Will accept 30A or 50A input and adjust accordingly. 30A input or in inverter-only mode will provide 120VAC to each leg. Power Assist...

    Charging from multiple sources

    One can have as many independent charging sources running concurrently as they like provided they are programmed properly for the voltage of one's battery bank. Examples (some or all at once, even multiples of a single type, different brands, etc.): Solar PV via MPPT Solar PV via PWM AC-DC...

    Open apology to @Steve_S

    @Steve_S, Please accept my apologies for so aggressively challenging you with regards to voltage "settling" of LFP cells. My experience with rapid settling of 40Ah CALB cells did not translate to the 280Ah Eve cells. My Eve cells obtained from Amy experienced dramatically lower settling...

    Autotransformer

    @the_colorist This new post is for you rather than hijacking our Argentinian's thread. There was another discussing in another thread about the Victron autotransformer with seemingly ambiguous instructions. It has a figure that appears to permit 120VAC input and 240VAC split phase output. Is...

    Testament to Rolls Surrette...

    2S2P S-605 for 12V, 936Ah This evening I pulled 81-84A (a little more current than the 4hr rate) from them for almost 6 hours. SG was 1.175 with voltage at 11.5V with 480Ah extracted. By Roll's published reference, they are very near 50% SoC based on a 4hr discharge curve and SG. That puts them...

    Paralleling LFP cells at rest to "balance" them

    Hypothesis: Paralleling cells at rest does almost nothing beneficial. While voltages may be equalized, their states of charge remain dramatically far apart. I decided to do an experiment. Take two CALB 40Ah LFP cells. Fully charge to 3.65V Fully discharge to 2.5V Charge ONE to 3.65V Let them...

    Outback Power Flexmax 60 80 stuck in "Charged"

    This is intended for Outback Flexmax 60 or 80 owners. My neighbor went with dual FM80 units for his 4kW array (2X 2kW) and 24V 24kWh battery. One has been working for maybe 3-4 months. The second was just installed this last weekend to work with his 25 year-old 1500W array because - that's what...

    How to not get completely scammed when purchasing solar panels.

    Too many times folks purchase panels from something like Wish or from anonymous on eBay, and they later realize they were sold LIES. Sanity check your purchase in the following two ways: Panel Length, L, in meters Panel Width, W, in meters. 1000W/m^2 * L * W * 0.2 = absolute maximum possible...

    Grid-tie concept question.

    36 285W panels recently acquired from Santan. Stickers intact, so not restricted to off-grid. Know enough to be dangerous with off-grid and have only a superficial vague understanding of grid-tie at the moment. South facing roof is messy and won't accommodate all of the panels. Some shading...

    Just picked up 36 285W STP285 from Santan Solar for $70 ea

    Received the promotional email: https://www.santansolar.com/suntech-285w-sale/ Online prices shows $80. Called to place an order to get the $70. Jason indicated it should be fixed on the website soon. Why did I buy 36 of them? My name is Steve, and I'm a solarholic. Srsly tho, I've been...

    Victron BMV Pros?

    Installed my BMV-702 today, and I have a new piece of info... "DC Power" - 15W in the screen cap above. This seems to fluctuate quite a bit and seems proportional to the AC loads. I have NO DC loads in the system. The only thing pulling DC is the Quattro (okay and the CCGC and MPPT). Is is...

    ERMEHGERD! VERCTRERN! V ER M

    OMG Victron. They just updated VRM so that the dashboard is updated real time, and it looks a lot like a CCGX display: I had my usual knee-jerk, "things were better back in the 'old days'" change-resistant reaction, but as my eyes lingered yet danced across the image, I soon became unable to...

    Victron ecosystem joy

    Just sharing a little of my personal joy... As I've mentioned ad nauseam, I'm a slap it together and make it work fast kinda guy. Sort out the details later, try to stay within squinting distance of "best practices," assess negative outcome probabilities and maybe pretty-it-up before I die...

    Overkill Solar BMS Balancing current?

    @OverkillSolar Looked at the BMS website. Looked at the manual. Searched the forum, but WAY too many things to sort through. Probably missed it somewhere, but I really did try. Questions: Active or passive balancing? Current? Thanks

    MPP Solar Pump Inverter / Experience with deep well, 230VAC single phase 3 hp pumps

    My neighbor has a beastly well pump that requires surge current equivalent to about 14kW. He runs it with his 24kW diesel generator. It's a deep well (700') Grundfos pump classified as 3hp/single phase 230VAC. 12A run, 60A surge A recent solar upgrade has made the genny necessary only for...

    Off-grid "Compound"

    One day I will post something meaningful into Show and tell that has more meat to it. This is just a fluff piece to introduce myself and to give a big picture view of stuff. Thanks to Will and the very helpful folks here. I feel like I've learned a lot on my own, but if I remember to listen...
