  • Post in thread: What was your worse DIY solar mistake ever?

    Buying like 30kw of panels and thinking it'll be simple to put on roof myself and get free energy. Then remembering I live in the woods surrounded by trees.
  • Post in thread: Victron is 10 times as expensive as Voltronic

    And this my friends is why my wife and I have separate bank accounts. The real problem comes when you buy more solar and equipment than you know what to do with. I say this as I'm sitting with 20kw of solar panels piled up in my yard realizing I didn't even measure my roof and have zero idea...
  • Post in thread: Off grid people ill-prepared

    One of my companies is an IT company and we have a 80/20 rule where 20% of people cause 80% of the problems. Some people are just cursed and no matter what we do we just know they'll continue to have issues. Also to the same point just because something's top tier doesn't mean it'll last...
  • Post in thread: If restarting from scratch knowing what you know now, how would you build your system differently?

    Invested in a hydraulic crimper and label maker . Wish I knew specs are more limitations and not recommendations. Over build and design for redundancy
  • Post in thread: Cost of solar

    I just tell the wife all the blue stuff is free. And that the generator kills kittens.
  • Post in thread: Going back and doing it right.

    I once made the mistake of showing my inverter bay on here :ROFLMAO: :ROFLMAO: :ROFLMAO: :ROFLMAO:
  • Post in thread: What percent charge do you get from dc-dc from alternator?

    Seems I might have been wrong. After pulling the 12v converters I found out the screwdriver didn't fit right so voltage adjuster was only half or so and go figure didn't find out until I swapped one out for the smart one. After turning it up it seems to be charging. Actually one 12v 70a...
  • Post in thread: Off grid people ill-prepared

    I do a lot of Disaster recovery/Business Continuity when it comes to IT so this is 2nd nature Just to repeat for those in the back label, label label. Spare wire, crimper tools and lugs. In an emergency this can replace fuses and other problems in the system. Checklists with A/B/C/D...
  • Post in thread: Cost of solar

    If it is not 100% solely used for solar it doesn't count against the addiction.
  • Post in thread: Smallest setup that will charge 48 volt batteries

    Well thats not nearly as fun. Here's mine after like an hour
  • Post in thread: 48v System Alternator Charging

    Technically a genset is an engine and a generator. A generator is just the part that creates energy, so larger systems are called genset as usually they're 2 separate pieces just combined.
  • Post in thread: Cargo trailer solar build

    The trailer inverter is just for things like drill battery chargers or maybe jump packs or something that doesn't really matter. I have a few laying around so figured since they're free it'll be nice to always have batteries fully charged. Trailer battery can only handle 30a/12v charge so I...
  • Post in thread: Work Trailer Mounting

    I used half height superstruts. Drilled right through the roof into the frame on the ceiling and used lag bolts with washers. Put lap sealant on the holes and along the bottom of the struts. It holds the roof down better and makes the panels almost impossible to see from the ground. You...
  • Post in thread: RV 48V to power 12v Loads

    I'm hoping Victron releases an Orion XS 48/12 as it's very efficient and has current limiting plus vedirect so you can automate. Even better if they do a 12/48 also. I could then have both setup so can go both ways and keep battery banks at even levels. Just think, we could have solar...
  • Post in thread: Ground source ductless (mini split) heat pump

    Yupp. This is why there aren't returns in bathrooms
  • Post in thread: 48v System Alternator Charging

    You want 1 or more Victron Orion DC to DC converters 12/48. You should have large enough alternators to have 100a+ (1200w) 48 volt alternators don't really exist. Balmar makes a 70a and 100a but they're a few grand. Newer jeeps and such have 48v alt but regardless you need to make it fit...
  • Post in thread: Victron Orion DC-DC strange interaction with alternator

    Sounds like your 7pin wiring on the truck side isn't nearly strong enough. When the Orion starts to pull 30a it drops the voltage then shuts off. 30a is the limit for the 7pin plug but most trucks only send 10amps or something and thin wiring.
  • Post in thread: Is victron a great company with great products or are they just like microsoft and the defacto brand leaders?

    Yes you can install their Venusos on a PI or other hardware and interact with Victron gear. But their cerbogx or even the CerboGX-S is well worth the price as you get everything right out of the box. It's like $200 for the S ($157 on ebay apparently) it has all the ports plus a bunch of...
  • Post in thread: 12v or 48v system in RV?

    Correct but the rating being higher is based on temps, that one is actually rated at 378a at 105c. The 445a is open air ambient temps like outside on a welder. Running that cable at 105c vs 75c (230a) introduces a ton more issues I'd assume. I'm correct in assuming that a cable running at...
  • Post in thread: Broke green wire insert victron shunt

    Push in the little orange area to unsprung the clasp that holds the wire
  • Post in thread: Victron Charge Controller Price Crash

    They've been top tier since they started in the 70s. Companies become top tier by offering the BEST products in the market. They gain market share by selling those products. Again I've yet to see a single one with a paid promo from Victron itself. Please send a video link of one
  • Post in thread: Increase BMS limits?

    You're right it can handle 200a it seems. The problem is somehow my voltage gets low and when I get below like 11v my entire firefly system restarts which causes my ACs to restart since the thermostats use 12v and are fused on the firefly. I noticed one of my lugs wasn't super tight so after...
  • Post in thread: 48v System Alternator Charging

    3000w is still 250a vs 62a. There's no disadvantage for OP, he still needs DC to DC converters although he could get the new ORION XS 50a ones. I'd kinda suggest going 24v if under 5000w as the Orion 12/24 are 70 and boost to 85a for like the same price of a 30a 12/12 or 12/48.
  • Post in thread: EV charger plug for RV?

    I'm rebuilding my power plugs and trying to find info on how the EV L2 chargers work and if there's a possibility to add a pair of J1772 plugs for charging my Lithium banks as well as a J1772 outlet for charging EV vehicle from my RV. I believe the J1772 requires some handshake and isn't...
  • Post in thread: Victron dual inverters split-phase but one 12V and other 48V?

    That's a great idea. I can limit the 12v input amperage.
  • Post in thread: build my own for my RV or buy new lifepo4 batteries.

    Built batteries have dropped to a point where DIY isn't much cheaper.
  • Post in thread: Cost of solar

    Im not calculating my cost but it's well over that. Couple differences for me. When I'm in my RV I don't want to have to fix things. Multiple redundancies and separate systems so if something breaks I can fix later and not ruin a trip. I also plan on emergency response and such so having a...
  • Post in thread: Turning certain loads on off idle?

    Low voltage disconnect when the battery is under 13v? I have one of these but haven't installed it yet, not sure how high it goes tho. https://www.bluesea.com/products/7635/m-LVD_Low_Voltage_Disconnect
  • Post in thread: Volkswagen, Porsche, and Audi finally say they will use Tesla’s EV charging plug

    For new years my daughter took her tesla from where she lives in Lexington, KY charging it up at a supercharger in Cincinnati then up to us in Columbus to pickup her boyfriend then stopped in Toledo to charge and finally to Kalamazoo/Portage MI where we spent new years...then back to drop off...
  • Post in thread: System Planning Check for Class C

    A Victron 12/24v DC DC converter would pull power from your alternator and you just use the on/off connected to accessory. They even have smart ones that'll detect voltage. We do mainly day trips and I've found that having 3k watts from the alternator allows us to run 2 ACs or heaters while...
