  • Post in thread: EG4 FlexBOSS 21 Discussion.

    I finally got the Ruixu Lithi2-16 working in closed communication with my Flexboss. Took a lot of hair pulling and finally a lifeline from The Emperor of Solar on this post...
  • Post in thread: Gridboss with Flexboss not handling 21kW pass-through

    Thank you for the summary. It seems like you/they are honing in on the issue. Hopefully they will find the smoking gun soon and put it to bed. I have nothing that will pull that sort of surge or go over the 200A GB limit so I will table my testing for now and keep an eye on this thread...
  • Post in thread: Flexboss21 and Gridboss with Ruixu Lithi2-16 Com Error W004 - Battery Status Check

    All hail the Emperor Of Solar!!! You are a goddamn genius! Type 1 on the inverter and PYLON on the battery seems to have done the trick. I can't tell you how happy that makes me ;) It did not work at all when the battery was set to luxpower btw regardless of the brand type. I will update...

  • Post in thread: Load/capacity testing setup to evaluate batteries

    Is there a particular Victron shunt someone can recommend. I have 2 48V wall mount batteries (may add one more later), Flexboss and Gridboss. Just getting started and want to test battery capacity and monitor a bit more. On the cheaper side if possible for now since I have dropped my entire...
  • Post in thread: Existing home from '93 ground-neutral bond is not code compliant. Is it safe?

    Thank you everyone for the great feedback! I feel much better about my setup in knowing it is more common than I realized. This forum and the collective knowledge of it's users is a godsend for DIYers like myself. The BEST!! Thanks Will Prowse.
  • Post in thread: How about a separate EG4 subforum?

    Hi Will. I know there are a lot of opinions when it comes to application design, implementation, and system maintenance. I'm a solar rook but have 30+ years in enterprise web apps and data analytics. It can be impossible to pigeon hole any post, question, or topic discussion into a single...
  • Post in thread: Can I wire two Ruixu Lithi2-16 batteries directly into Flexboss inverter without a busbar or fuse?

    I am adding a second Ruixu Lithi2-16 to my system. There are two positive and two negative battery ports on the Flexboss. Can I plug both batteries directly into the Flexboss without using a busbar? Are any additional fuses needed? The Flexboss has an integrated 300A breaker and each battery...
  • Post in thread: Ruixu Lithi2-16 parallel with eg4 batteries

    FYI, I recently installed the Gridboss, Flexboss and lithi2-16. To get closed coms working I had to set the battery inverter to PYLON and the lithium battery brand to type 1 in the inverter settings. Otherwise I got a communication error or status check notice and the inverter went into...
  • Post in thread: Gridboss Smart Loads

    The fans kick on for me between 6500-7000W. Fairly loud fans but they are in the shop so do not care. It is silent below that. Might be worth getting a second inverter to limit high production if a quiet environment is key. I'v heard they are a little quieter than the other EG4 hybrid...
  • Post in thread: My EG4 FlexBOSS 21 questions

    You will need the monitor website, android/Apple app, or a LCD screen to configure anything. Default settings are unlikely to run as you wish. If Solar Assistant is able to integrate that would be another option. If you are going to use a Gridboss the app or monitor site (or SA?) will be...
  • Post in thread: Flexboss/Gridboss versus 18kpv

    The appeal for me was the configurable smart ports, load shedding, and the ability to place the inverter and battery in another room with better heat. Also super easy to add second or third inverter. The Gridboss can replace the main disconnect and manual transfer switch among other things...
  • Post in thread: My EG4 FlexBOSS 21 questions

    Not sure about SA, the EG4 app does use WiFi, either local or internet connected to access while away from the unit. Cat6+\RJ45 cables are used for fast communications between the inverter(s) and Gridboss and for closed loop coms from master inverter to battery bank if using lithium. They are...
  • Post in thread: Flexboss21 and Gridboss with Ruixu Lithi2-16 Com Error W004 - Battery Status Check

    I recently installed the Gridboss and Flexboss21 with the ruixu Lithi2-16 wallmount battery. This is my first solar install. Any tips, troubleshooting or support resources would be greatly appreciated. I've been working on this for over a week and I am out of ideas. Here is the issue: I get...
  • Post in thread: Safety Check with new EG4-FlexBOSS21 Inverter / GridBoss + large array

    I'm liking the Lumina Solar Space 535w Bifacial Solar Panel | SS8-72HD-535M from signature solar for this setup. $160 for 535w and fits nicely into mppt 1 or 2 with 16 pannels (2x8 pannel arrays) or 9-10 pannels on mppt 3.
  • Post in thread: EG4 GridBOSS Deep Dive

    My understanding is that you can have only one GridBoss and up to three hybrid inverters in your entire setup. The GridBoss can separate from the inverter and batteries but only one boss in the office.
  • Post in thread: My EG4 FlexBOSS 21 questions

    The connected website monitor at https://monitor.eg4electronics.com/ is not required. If the dongle is not connected to your router you will need to connect your smart device to the local server provided by the dongle and use the local connection option in the EG4 smartphone app to configure...
  • Post in thread: EG4 GridBOSS Deep Dive

    The manual indicates only copper connections throughout the GridBoss. I currently have alumninm from the meeter into the main panel and to a 100A sub panel. I heard in an interview with an EG4 production engineer that said they "didn't have a problem with alumninum" but the 200A Eaton breaker...
  • Post in thread: Existing home from '93 ground-neutral bond is not code compliant. Is it safe?

    I found two ground neutral bonds in my existing house wiring that was built in 1993. One is at the pole after the meter at the first service disconnect and another in the main fuse panel in the house that is connected to a grounding rod near the panel. I know it will clear faults since I have...
  • Post in thread: Gridboss with Flexboss not handling 21kW pass-through

    I also have the GridBoss/Flexboss combo but not enough load to max it out like you do. I wonder if setting the Discharge Current Limit to something low like 50A then placing a 4-5k load on the system would cause the FB to run short and need the grid for help? I will test tomorrow during...
  • Post in thread: Flexboss21 and Gridboss with Ruixu Lithi2-16 Com Error W004 - Battery Status Check

    That makes some sense. Are you referring to the float and absorb voltages under the "old settings". I'll need to do some more research on this. I have it set to 56.8 and 54.6 as indicated in the battery doc. This is my first experience with solar and energy storage so forgive my ignorance...
  • Post in thread: How about a separate EG4 subforum?

    Gotcha. Without the right systems in place it's not possible. I was thinking something along the lines of my favorite tech forum https://stackoverflow.com/ . Everything is tag based and searchable, dynamically tracking tags you follow and other trending topics. It also allows for posters to...
  • Post in thread: Gridboss with Flexboss not handling 21kW pass-through

    Do you get the same behavior if you turn off battery backup mode and go to "Self Consumption"? Apologies if I missed this.
  • Post in thread: Flexboss21 and Gridboss with Ruixu Lithi2-16 Com Error W004 - Battery Status Check

    Yes, I have seen this, several times actually, trying to glean a new idea to try (thanks Will for showing how it SHOULD work). I have tried setting it as Luxpower on the battery and lithium type 6 in the inverter settings but I get this error. I also tried as type 4 per S2 support and type 0...
  • Post in thread: Adding RUiXU Lithi2-16 batteries to 18 KPV with a rack of EG4-LL’s

    Did you go with the Lithi2-16 in the end? I am having coms issues with just the Lithi2 and Flexboss. Not sure if it is a software bug with the new system or possible hardware issue. Waiting to hear from Ruixu support which takes 3+ days to turn each message around so slow... Let me know if...

  • Post in thread: Flexboss21 and Gridboss with Ruixu Lithi2-16 Com Error W004 - Battery Status Check

    That is one combo that I have not tried. I will give it a go and let you know. The changeover outage kills my internet so it may take a min.... Should I totally disconnect power and battery to the flexboss after making the change or does going from standby to lithium with the automatic...
  • Post in thread: FlexBoss with parallel Hyperion panels, is it going to smoke?

    I'm not sure what you are using for racking but for my case the mounts were more expensive than the panels. I was looking at the Solar Space 535w and you can use 8 fewer panels and get around 1500 more Watts out of the system! Plus no warnings on the calculator.
  • Post in thread: 48V Waterproof Inverter Options?

    Maybe a luggage topper to house the sensitive bits? Mount it directly to your v5 cart... A little venting underneath, channel the drips a bit, a few flames painted on the sides... And you can get away from the heavy hybrid inverter.
  • Post in thread: Flexboss/Gridboss versus 18kpv

    Where are you getting these numbers from? is it in the doc or through testing?
