    How much?

    If they have a butler but still a generator interlock plate, not a full whole house standby with an ATS, their priorities are a bit messed up. Maybe they finally upgraded and that’s why these panels got rotated out.

    How much?

    The generator interlock plate is a nice feature.

    Help with a DIY battery bank

    Also one thing to keep in mind 2200ah of LiFePo is about the same as ~3000ah due to usability limitation of FLA and efficiency gains of LiFePo while charging. It’d be best to plan for a robust system one for one swap, but you maybe way over building the new bank compared to your current use...

    Help with a DIY battery bank

    An external relay operated by a shunt can control multiple contacts/devices at once. Do you need multiple things operated at different SOC values?

    Help with a DIY battery bank

    So 64 280ah cells at say $90 is what $5700? but replacing an inverter and some lightning protection is too costly?? Btw check out this thread for some other 8p8s build wisdom...

    Multiplus II AC input wire question

    I wonder if you doubled up the 12awg conductor in a larger ferrule would do the trick.

    Multiplus II AC input wire question

    In their “loop” video Dexter uses romex, but they recommend SOOW with ferrules. Also that 6awg is for max power assist of 70a. I can’t imagine victron requires the minimum awg as the max awg of those spring connectors. I’m gonna try and see of 12awg solid slides out of the spring on my 24v3k.

    First use of cells

    Even then any BMS worth owning should be able to handle a bit of unbalanced cells. It’s just a matter of time to let a BMS do its magic.

    Multiplus II AC input wire question

    What’s the size of the bare ground wire? 10 or 8awg? How’s that feel in the spring terminal compared to the 6awg?

    To shunt or not to shunt?

    Gotcha, I’d say shunt, always shunt.

    They are mine!

    But prob gained a ton in efficiency. What’s the no load losses of those 4 units?

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

    Best one is the ones you can find locally and not have to deal with any possible shipping damage.

    Battery Post Heat

    That smaller gauge voltage sensing wire can be moved to another battery terminal.

    To shunt or not to shunt?

    I thought MPII split phase set ups needed one battery voltage to feed both legs of the inverters to keep things happy.

    Building a power cart, need some GFCI clarification

    Just stay away from GFIC with Arc fault. If you’re looking to add say a 70a load center with say a Square D QO breaker. Arc fault protection does not like to play well with large brushed motors, you know the large motors that constantly arc when running. GFIC is all you’d need.

    Victron Basic Setup w/ AC Input Plug-in Cord

    Thanks I’ll keep that in mind when I need more space. Any issues with the 5/16th bolt working with the 3/8 hole of the MRBF holder?

    Victron system - Cerbo wiring neatness

    My idea was to keep it as a “MP load center” with outlets, 15a duplexs with GFIC and TT30 with GFIC breaker, so I could use it at home in the winter to power our furnace during a quick winter storm. The solar input and combiner box most likely will remain separate.

    Victron system - Cerbo wiring neatness

    You are right I’m now in the process of laying things out on plywood dry fitting things for layout, the MPII is a heavy beast, then another 20-30lbs of Lynx, load center and outlet boxes, that even without the MPPT.

    EVE Official Alibaba Store, the end of Luyuan and other alibaba sellers?

    I’m 100% certain i don’t know its eve until someone shows delivered cells in their hands from an order.

    Extra/Auxilary grounding rods..... Don't do it.

    You’re right, lightning wants to find ground ground, so if there is a direct path to ground from an array or and metal structure straight down, it won’t travel back to your panel . This is the same for the radio tower, send it straight to ground not back to sensitive equipment.

    JK-B2A24S in Parallel question

    There are certain circumstances where they may not current share load evenly (even with proper wiring) so as long as you don’t need to exceed one BMS worth of current you’ll be fine.

    Purchased from "BATTERY FINDS"

    Capacity tests are just as useless as QR codes fake or real and “test reports”. Everything is grade b anyone saying otherwise just wants to feel good with their purchase.

    Yet again another example top balancing isn’t worth it. Any bulging of the cells?

    Terminal Blocks and Class 6 (Extra Fine Stranded) Conductors

    Not to pry, but any chance you were employed by Orsted? It’s crazy at the challenges they’ve been facing here in the US and the write downs they’ve incurred.

    Configuring Victron Multiplus with MK3-USB

    So the cable worked for the cerbo but didn’t work for the Mk3, or at least you swapped cables and it worked?

    New system lasting less than an hour.

    whoops, I’m sorry I miss read your post. If your system is all in parallel, just verify proper wiring for current sharing and also make sure you hit 100% charge routinely, otherwise you may lose a few AH.
