    Possible connecting Studer XTM 24-3500 to a Victron Venus OS running on Raspi

    Hi all, My Victron system is monitored by Venus OS on a raspberry pi and I want to connect 2x Studer XTM 24-3500 inverter/charger to the Cerboo GX/Venus os. Is this possible and yes how? Background: I am having an all Victron installation (except of BMS Electrodacus) in 12 V on my catamaran and...

    Best battery for electric windlass

    Guys any Lithium above 150AH is capable of operating your windlass BUT your BMS most likely not as the 4-10x times voltage surge will fry it. This is for all BMS in drop in batteries (unless explicitly stated) and all BMS that carry current like overkill or Dali and alike. Exception are non...

    Design review please

    Yes, all switches BlueSea exactly speced for the use. 3p4S connected in 6 cells in 2 rows side by side with 10mmx20mm tinned copper busbars, made from 12 Lishen 272AH grade A cells matched from factory. every cell individually charged and top balanced, then all 12 cells put in parallel and...

    Solar panels 12v versus 24v & series wiring

    You don‘t wanna series connect panels on a boat, as shading to one (which will always happen) takes out all panels connected to it in series. Also Performance is Limited to worst panel in series. Avoid 12V panels, go 40V ones. 2nd use bifacial panels as they work with diffusion light and at sea...

    What Busbar size for 600A in 3P4S 816AH 12V, different sources different sizes and different ratings…

    Hi, will just use 5x20 tin plated cooper bar doubled up so 10x20=200sqmm. Thats whats available in France and a friend is bringing to Canary islands today. Should be good for my max 600A if Victron quotes 240sqmm is good for 1000A... Will do a stress test with all fired up and see if it heats...

    Design review please

    What’s overcomplex? It’s a cat with 2 engine rooms, 2 inverters and 3 MPPT. 3 MPPT instead one big because the bifacial solar deliver 15% more then on one big plus redundancies. That’s also main charge source… Yes I am pulling around 250A in normal operation cooking but occasionally 450A. I am...

    DIY Bus Bars from copper bar

    These studs are by far too short for the busbars you used. Also sinking in the nuts into the busbar is contraproducrive. Let me guess you glued in the studs with loctide and later figured out you need thicker busbars… Also on the rear cells there should be 3 busbars connecting all 3 cells in...

    DIY Bus Bars from copper bar

    How many amps do you draw in total? Big inverters and eg electric galley? The 1/4“ tinned copper bars are good for 300A continuous. I you are running a 3kw inverter plus rest of your boat you are above that. I doubled them up as I am pulling 500A from 5,9kw inverter, so suggest to better get...

    Electrodacus, how do I connect remote of Victron Phönix smart ip43 Grid charger

    The whole charger gets super hot, cannot touch it and at the heat sink I measured between 82-85 degrees Celsius after 30min of charging. Returned it and switched to a 12/3000/16 MUltiplus which also has a 120A charger build in. Have the feeling that private equity reached their new products too...

    Design review please

    At the moment I keep the quite new 2x90AH FLA Starter BB and STB 300AH FLA Hybrid house/starter till I have some experience with the Lifepo4 install and system runs stable. Then I will delete all FLA except of one 90AH FLA starter per engine to offset the 70kg+ weight gain per hull for the...

    Design review please

    Hi all, so I finally finished the installation wiring diagram of my 840AH 12V LIthium house bank on my catamaran. Could you please review the diagram. I use the Electrodacus BMS which controls everything via remote on/off and has full control over the load/charge on cell level. its also current...

    Sailboat upgrade to EVE LiFePO4 600ah @ 12v - design review

    It depends induction stove work differently. They are 3 kinds and You need to measure the actual current used on all settings to figure out how they work. The worst once are always using max wattage and just pulse slower or faster depending on setting, these ones avoid... Mostly the cheap ones...
