  • Post in thread: 12v vs 24v?

    Briefly looking at the specs on the Victron controller, it appears that you are way over paneled and not actually using much of your solar. If I am reading the specs right the 100/50 can only handle 700watts on a 12v battery...
  • Post in thread: Top charging the EG4-WallMount Indoor Battery

    If the protection kicks in you should get an alarm state on the battery. Red light above the green light. With the over voltage at the cell level the BMS would stop charging until that cell volage comes back into range. Not certain what over current would do. Either trip the battery breaker...
  • Post in thread: How do Rapid Shut Down modules work? Which side does the switching?

    My very limited experience is with Tigo. I do not know about other brands or other methodology. My understanding is that the RSD on Solar panels DOES NOT shut down the panel itself. NO opening of circuits. It just reduces the output voltage down to a very small amount (magic boxes somehow)...
  • Post in thread: EG4 6000xp Battery Metrics

    I would love to see the inverter consumption being shown on the web monitor. Especially if it could be a separate line item. Thanks, LilMt
  • Post in thread: Looking for Advice -- System Monitoring and control

    Easiest solution in my opinion is to hang a tablet on the wall, add a usb charger and have it logged in to the web monitor? Set the screen save to not time out if you can.
  • Post in thread: 6000xp RSD and generator

    I was able to test the RSD with the Gen running today. The Gen does shutdown with RSD.
  • Post in thread: Top charging the EG4-WallMount Indoor Battery

    Here is the image with the inverter saying the batteries are at 99% You can see one battery is 100% but still drawing 1 amp. I am assuming this is cell balancing. The other battery is still charging at 7.3 amp. My guess is that this is the BMS's doing their job. The lower input in because of...
  • Post in thread: 220 to 110 step down transformer

    Thank you for the information, I will look into it. Just not certain if I am being overly cautious about trying to balance my AC legs or if it is a good idea. Thanks.
  • Post in thread: Top charging the EG4-WallMount Indoor Battery

    On the front screen of the battery, you can go to settings and then I think voltage. If I remember right this will show you some of the per cell information. I cannot remember what all it shows, or if that is even the correct way to get there. But it might be worth taking a peek.
  • Post in thread: Bonding of battery case to inverter (EG4 6000xp)

    I recently bought and am preparing to commission an EG4 6000xp with two of the wall mount batteries. Reading through the instruction for both the battery and the inverter I do not see about bonding the battery to the inverter. I found that the conduit box has a bonding jumper to bond to the...
  • Post in thread: Top charging the EG4-WallMount Indoor Battery

    I am not certain, but from what little I have read on the subject, I think it is one battery at a time as I believe you need to set the battery ID to 64 for BMS Tools to talk to the battery not certain at all though.
  • Post in thread: 6000xp RSD and generator

    I was wondering if an RSD is triggered on a 6000xp using a remote button on the SW contacts, does the generator contacts go open? Scenario: generator is running, emergency situation arises that requires RSD. Hit the big red button and the inverter ends up staying powered because it is running...
  • Post in thread: EG4 Web Monitor - battery detailed info on all batteries , am I going mad?

    Are you charging using Gen, Solar, or Grid? If it is Gen or Grid, I believe you can set those to charge based on Voltage - PV no such luck. One thing to note, when I switched from Bat type 0 to bat type 1 it did help "some" with my drift. I went from 7-8 percent to 2-3 percent. I have also...
  • Post in thread: Top charging the EG4-WallMount Indoor Battery

    I have a 6000xp and I use CAN. From what I can tell by watching the batteries on the monitoring site. I appear that when one battery (doesn't matter slave or master) get full, it then stops charging and the other battery(ies) continue charging. I think there is some logic in them that...
  • Post in thread: 220 to 110 step down transformer

    Thanks for the info. My water pump is actually a submerged well pump and is 120 only. (I should have said that at the beginning). It is currently no exceeding the line limit or even the imbalance threshold. So, I think everything is okay. Maybe next year I will update that well pump to a 240...
  • Post in thread: Help me understand

    The 6000xp has inputs for 2 strings. Could you have 2 strings of 8 (1 for each input) so that you are not hitting the max amperage (and getting clipped) on a single input? All depends on the amp rating of the panels of course. You may be fine on a series parallel array if the combined...
  • Post in thread: EG4 Web Monitor - battery detailed info on all batteries , am I going mad?

    I didn't notice a change in mine for a few charge cycles. About a weeks worth.
  • Post in thread: Up and running, and now a few questions and comments:

    I have an off-grid home (no commercial power at all). I use solar and generator for my energy needs. I have a Kohler 12KW generator as well as a 9KW Harbor freight as a back up. Old system was a Midnite Classic 250, 3s2p Trina Solar 405watt, 8 Renogy 200ah for 48V 400ah, Magnasine 4448...
  • Post in thread: Generator Auto Start EG4 6000XP Kubota GL7000

    Gen cooldown is a much-needed function, gen warmup would also be very helpful. Thanks, LilMt
  • Post in thread: 220 to 110 step down transformer

    Probably a silly questions but... I just got and installed a new 6000XP at my off grid place. My water pump is 110V I would like to try to balance my legs as much as possible and I was wondering the following: At the water pump I have both a 110 and a 220 outlet. Can (should) I use a 220 to...
  • Post in thread: Eg4 6000xp not showing num batteries In parallel

    Is the cable needed to update EG4 batteries dependent on battery type? I have the indoor wallmount batteries, is there a part number or something I could get to ensure I order the correct one? Also, is the firmware update cable the same as the cable needed to use BMS tools? (That date and...
  • Post in thread: Top charging the EG4-WallMount Indoor Battery

    Based on my own very limited experience, it appears that the current into these batteries stays mighty high all the way through the charge cycle. Also, according to the spec sheets, the BMS's do have protection. One thing I noticed was that it took a few cycles to get the BMS's and the...
  • Post in thread: Top charging the EG4-WallMount Indoor Battery

    Looks as if Cell Balancing is complete: and the BMS is now disallowing charging to the batteries: As I mentioned this is ALL conjecture on my part. Take it with a grain of salt unless one of the BMS guru's chime in to confirm or deny. :) Good luck and have a great day, LilMt
  • Post in thread: Top charging the EG4-WallMount Indoor Battery

    I would suggest opening a ticket with your reseller. To my little brain that 10amp differential seems a fairly big divergence but it would probably be best to ge a professional answer. Perhaps an EG4 tech will chime in.
