  • Anybody use a hitch receiver on their excavator to haul a trailer?

    Saw a couple videos of people welding receivers on the blades of their mini-ex to haul trailers. Anybody done something like this? If so, how did you calculate trailer size for your excavator?
  • EG4 Chargeverter display, does it show current drop as BMS throttles charge?

    I see the chargeverter shows battery voltage and that increases as the battery is being charged and it shows current (you set what current you want to go to the battery). My question is...if I'm charging a battery with a BMS that starts to limit the current as it gets full, will that be...
  • Blue Seas 125A t-fuse....stud torque really 3/8" pounds? Finger tight only?

    I'm trying to put my t-fuses in the t-fuse holder and if I'm reading this spec sheet correctly, I'm supposed to only torque the t-fuse to .34NM? My torque wrench min torque is 60 inch pounds, so if this is really the number I'm going to have to figure something out. That number seems so low...
  • What is powering my AC/DC loads in this Victron Remote Console view?

    Batteries just charged up to full and the MPPT went from throttling from 6KW coming in to just a few watts as the batteries requested less, and then it stopped charging and started showing -16W for some reason. If we turn on a bigger AC load the MPPT then starts supplying power. But I'm trying...
  • Super noob question - are amps going to battery split between + and - cables?

    MPPT puts out 100A to a single battery connected to the bus with a positive and negative cable. Is it 100A going through both cables, or 50A going through each to the battery?
  • 5s3p 247V running 350 feet to a Victron SmartSolar MPPT 250/100 VE = 1 AWG wire??

    The VOC after temp correction is 247V and I have a long run of 350 feet to the MPPT. Does it pass the smell test that I would need 1 AWG wire to make that happen? Many thanks in advance for any help...
  • Electric tracked ATV

    Anybody got one? I've seen some electric ATVs that have been put on the market, but I'm not sure any can handle tracks and we need tracks where we're at. Argo (which is our daily driver) has an electric model but it's super expensive and unfortunately they didn't use individual motors on each...
  • Any issue connecting 4AWG cable to bus like this?

    The lugs for the Pylontech 4AWG cables won't fit on the large bus bar terminals. But the Blue Sea Power Bar 1000 has these smaller terminals. I would be connecting 8 of these 4AWG cables to the bus bar, only one shown here. Each Pylontech cable will carry a max of 100A in this 48V system...
  • What cable temperature to use for determining cable ampacity for sizing circuit breaker? 60C?

    Trying to make sure I get the correct circuit breaker to protect wires, but ampacity changes with cable temperature. I saw some NEC reference that I think indicates 60C should be used as the ampacity of the cable. But cable listing I'm looking at only provides ampacity for 40C, so I'm not sure...
  • 8 Pylontech batteries, double stacking 2 banks of 4, or single stacking 4 banks of 2?

    I've got 8 x US5000, 4 long positive cables, and 4 long negative cables (same lengths in either scenario). The question is where to put those cables in the battery bank. The network cables will talk to the system and treat it as one big battery bank of 8 regardless, from what I understand, but...
  • Tricks for cutting long wires of equal length?

    I've got to cut some 130 foot 10 AWG wires for an install, just want to make sure they're actually equal length. Any tricks anybody use for this? I saw a device called a CutFox 10 that is a machine that does this (not sure if it would do 130 foot length or not) but haven't seen any reviews of...
  • How to avoid Victron capacitors from rushing the batteries on setup? Nothing I'm trying is working...

    How to avoid Victron capacitors from rushing batteries when setting up???? I thought I had got everything set up to avoid the Victron MPPT RS capacitors and the Victron Quattro capacitors from demanding a massive in rush from my "battery bank." I bought a light bulb to use as a resistor and used...
  • Is there such a thing as a Class K PV wire? Can any 10 AWG single conductor wire be used as PV wire?

    The PV wire we have purchased and see online is 10 AWG 7 strand, or 19 strand wire. But Victron requires Class K PV wire to go into its MPPT RS units. I have found Class K 10 AWG wire (tinned copper) -- would I be okay slapping some MC4 connectors on it and using it as my PV wire? Wire specs:
  • Sanity Check Requested - Wiring Honda 7000 generator into Quattro 48/15000

    We have a Honda 7000 generator (North American) that puts out 120/240 with a 4 prong connection. I assume that is putting out two hots of 120V to make the 240V. From what I understand this generator is not grounded if that matters to this scenario. And I"ll set the Quattro Hz to the North...
  • Taking a Dremel to a Victron MPPT to make room for 4/0 cables (which will touch on the terminals), bad idea?

    I think this is okay, but figured I'd check with the collective expertise before I start modifying this thing. My Victron MPPT RS 450/200 uses two sets of DC cables to connect to the bus. And it has an access slot that is just a bit too narrow for these 4/0 cables. My questions are: a) any...
  • Victron MPPT RS, Float Voltage, VOC...does the 8*Float Limit require a Temp Correction?

    Continuing my habit of learning something new after I make expensive decisions on what I think I know... I have seven arrays of 7 x LG440N2T-E6 bifacial panels in series, with each array connected into a tracker of two MPPT RS 450/200 units. When I sized the arrays, then designed ground mounts...
  • Anybody sell custom bus bars?

    Anybody know of a company that sells custom bus bars? I'd like to get a 24 terminal tin plated copper bus bar made by somebody who knows what they're doing.
  • Making an elevated wood shelf to hold up 1400 pounds of batteries...

    So we've got our 8 Pylontech batteries in our solar shed which is located above a root cellar. Turns out the Alaska winters laugh at my attempt to insulate the batteries. So I'm going to move them down into the root cellar with room to double them, into a super insulated wood shelf. The shelf...
  • Quattro 48/15000 or Multiplus II 48/15000 -- which is better (for our application)?

    We are almost ready to install our completely off grid, and to remain off grid, solar system. We own and will implement everything in the system as is, according to the design below, with the exception of the Multiplus II 48/15000 shown in the top left of our diagram (we planned to order it but...
  • Charging Batteries with Chargeverter - Am I Doing it Right?

    So I've got my Honda 7000 powering an EG4 Chargeverter which is wired into my 48V bus bar. I have it set to charge my 8 x Pylontech US5000 batteries at 52V and 100A. I started off with my bank showing 91% SOC and I started screen capping at around 50.7V. AC loads were about 300W. The battery...
  • Any issue supplying DC bus bar with two different voltages for Inverter?

    Got a welder coming to use a 50amp 240V outlet for a job on our off grid homestead. Got 38KW of lithium supplying the inverter. His welder is going to take the full 240V and 50A to work. If his job takes longer than I think it will, and so the bank gets depleted more than I think it will...
  • How big is too big when it comes to a floating off grid system?

    Trying to think a bit more about grounding on our off grid system. Is 25KW of PV too large to have an off grid system floating, requiring it to be grounded?
  • One large solar array to service two different physical locations on a property?

    Is this doable? I have an off grid property and one area gets good sun, the rest doesn't. But I built our cabin 500-700 feet away from this good solar location and we have another cabin we're gonna build on a different part of the property that's also about 500 feet from the good sun location...
  • Sizing Bifacial PV Strings for Solar Charge Controller -- double confused here

    I'm trying to figure out how much PV (LG 440N2T-E6 panels) I can plug into a Victron 450/200 SCC. From what I understand, the SCC has 4 trackers where PV can be plugged in. Each tracker is limited to accepting 450volt and 20 amps. I know I can wire up 7 panels in series for a total voltage of...
  • PV connection torque for Victron MPPT RS 450/200 not specified?

    About to hook my PV up into my MPPT RS but the manual only provides torque settings for the battery connections, not the PV connections. Weird given how they require super stranded PV wire (we're using 84 strand 10 AWG) for those plastic terminal connections and that's a big deal for a safe...
  • Max current to charge a battery bank - is it limited to the current one battery can get?

    If a 48V battery can only be charged with a max of 100 amps, and you wire two of them in parallel, can that bank then receive 200 amps for charging or is it limited to the 100 amps of a single battery? Many thanks for the help! After a search I saw somebody else ask this and the answer...
  • Bus bar links slightly angled off...issue?

    The two inner fuse holders are angled off (can't fit four of them up there otherwise and don't want to lengthen the cables to put them on the bottom row if I don't have to). The two inner fuse holders are for the two positives of my MPPT. So the cables are the same lengths, but there could...
  • Momentary "low voltage" warning on Pylontech....concerning?

    Battery voltage is above 49V so I'm not sure why this error came up. From the manual: Low Voltage: When the battery discharges to 44.5V or less, battery protection will turn on. Then there are the simultaneous "high voltage" and "low temperature" warnings. None of those should have popped up...
  • Do I care if my generator is bonded neutral when powering an EG4 Chargeverter?

    I know there are some issues with whether a generator is bonded neutral or floating neutral when its connected to the inverter, but in my case I am having my generator power an EG4 chargeverter that is connected straight to the DC bus bar. So should I care if the generator is bonded neutral or...
  • 10.6KW bifacial off grid ground array powering multiple locations 500 feet away

    Hello all, I had previously been planning on installing PV at our cabin that we just built last summer as detailed in this thread. But thanks to the many great inputs from people we got in that discussion, we've changed our original vision a lot. Now we are planning on using LG440N2T-E6...
