  • Post in thread: Single vs. Multiple Class-T Fuses

    I took my EVE280 cells and unrolled them then laid T-Fuses out on them and rolled them back up to be extra safe before commissioning mine :/
  • Post in thread: What Would Cause LiFeP04 Battery Voltage To Spike During Charging ? XW Pro

    Had a similar issue, turned out to be a very loose connection. If you are taking the previously stated advice of disassembling and testing each battery you might end up "fixing" it when you reassemble it all ;)
  • Post in thread: Solar array ground mount ballast.

    Updating a little as I had to shift materials. 4x4 = drk brn 2x6 = lt brn 2x8 = green Flipped panel orientation to reduce footprint, this makes the diagonals 12ft. Added 3 sets of wire cross braces ... going to pretension with gripples, will tie blocks to ground with same wire / gripples and...
  • Post in thread: DIY Large insulated water drain back tank?

    16ga ***This is not an original concept*** 12 panels build a tank, each panel attached top/bottom to the adjacent panel. A stack of 4 panels go on top the previous, sheet metal corners with 2 screws per C Channel intersection min, likely might do 4. If I don't go this route I might build it...
  • Post in thread: free standing service panel (pedestal)

    A service panel is where you would normally mount your disconnect, meter, and maybe junction boxes and you would get "service" from the power company to that panel. Typically these are two 4x4's burred at least 4 ft in the ground (we can't do that) and then plywood attached to that. We have...
  • Post in thread: Power Outage Causes EG4 Operation Faults

    in our place we installed a Reliance manual transfer switch for our critical loads. We then wired the circuits we wanted to run on it and the GEN side of the transfer switch was set to the output of the Inverter. We just keep those loads always set to GEN ... power goes out, we don't know about...
  • Post in thread: (image intensive) Re-purposing Radian Load Center for Battery bank and SMA SI Load Center

    I picked up a Outback radian box (empty) and a Outback Radian Load center off Craigslist earlier this year for $150 and planned on using it but didn't know where ... Originally I thought the Outback Radian box had all the components in it but found out later it did not so I decided it would...
  • Post in thread: Batrium Installation

    EDIT: YES ... There is no PWR input on the Expansion 3 ... it gets it from the connected watchmon. The limits are the voltages you can send through relays SSR's up to 65vdc, the manual relays 30vdc ... both 5A
  • Post in thread: Two MN200 classics with breakers

    For those of you who have read my other posts you know I purchased a sma Prewired system from MN with two 200 classics then decided to go full SMA and do AC coupled. I don't need the classics and have removed them, their wires, breakers, sensors, etc from the control center. These have never...
  • Post in thread: Power Outage Causes EG4 Operation Faults

    Could use a split bus panel ? Top of the panel is feed by mains and has mains only loads. There would be a breaker here which goes into AIO AC IN. Then AIO AC Out goes to the bottom part of the panel where any loads which should be on the AIO are found. Otherwise ... you need the POCO to go to...
  • Post in thread: free standing service panel (pedestal)

    Visited the place we bought our 2x2x4 retaining wall blocks from for our array today to pick the last two up. Turns out they make a cover for underground electrical vaults which are roughly 6+" x 4'x5' ... thinking of picking three up and partially burying them in the ground to use as the...
  • Post in thread: Batrium SMA Sunny Island Integration issue?

    @ChrisFullPower ... turns out my IXXAT device wasn't setup to read at pins 4/5 with the version I have ... I am now tracking traffic on the can network live while the SMA is plugged up after switching to the right pins on my db9 connector Going to let it run a day then review the logs which...
  • Post in thread: Ground Mounting Solar Evacuated Tubes

    thought maybe you were using it for HRH as well ;)
  • Post in thread: Power Outage Causes EG4 Operation Faults

    Solved it with MSPaint. Really big unicorn diodes and the switch of the ATS on the POCO side of the equation ... POCO / AC IN / AC OUT ... one panel ;)
  • Post in thread: DIY Large insulated water drain back tank?

    I have seen a lot of builds for DIY storage tanks as well as indoor koi ponds that seem to use wood, typically 2x6 on edge 6" OC bolted together and tied together with plywood on either side, and I was thinking of using scrap C Channel I have left over from building. The C Channel is 16ga...
  • Post in thread: anyone recognize this brand of manifold?

    UPDATE: For those that come across this and wondered what my solution was, I ended up swagging the manifold coper pipe up a bit to allow for a 3/4 brass union to be soldered on.
  • Post in thread: Final LFP Charging settings with Batrium BMS?

    Same old 3.3 settled voltage state, not being able to climb past with the .1A at 98% SoC. Will now set to the non-longlife setting, ramp start / end voltages match, set SoC manually to 88 to trigger a charging cycle given the battery is at 3.3 right now, and selected default settings for...
  • Post in thread: Ground Mounting Solar Evacuated Tubes

    Its a double envelope home that has two massive earth tubes in the Thermal Buffer Zone ... which is where our HRV will pull new air from to condition the living space air. The air changes per hour will be good for living. I have seen those ... pretty cool, first time I have ever heard someone...
  • Post in thread: shared neutral from combiner box?

    Thank you. We are going to be setting up our system this year and it should be interesting for sure. There are some other posts I plan to make soon which haven't been covered yet so I hope to contribute to the community where I can.
  • Post in thread: Ground Mounting Solar Evacuated Tubes

    Will reply to my own thread as I find information. Solar Hot Water Rules of Thumb Load Est: 20gal / person / day (seems high vs the way we use hot water) Collector Sizing: 1sqft per gal hot water needed Storage: 1(cold areas) - 2 (warmer areas) gal for each sqft of collector This means given I...
  • Post in thread: Batrium Watchmon Install

    Thank you both for your input. Pictured, although redrawn by hand as a rough representation, is the WatchMoCore + CellMate-K9 bundle ? https://www.batrium.com/collections/kits/products/watchmon-core-k9 Because it is built into the prewired SMA Midnite Panel? It wont be hard to ensure it is...
  • Post in thread: (image intensive) Re-purposing Radian Load Center for Battery bank and SMA SI Load Center

    Updates: Got everything wired up, was about to turn the ON switch "live" in video when I saw it wouldn't work as I expected because the battery was connected to the contactor then the contactor to the plate ... the issue being nothing would get power upon switching the switch to ON :D I had...
  • Post in thread: Batrium SMA Sunny Island Integration issue?

    @ChrisFullPower when you get it running let me know your firmware version ... I recall mine being ahead of what was on the site for download.
  • Post in thread: DIY Large insulated water drain back tank?

    Oh it will be lol ... our original "plan" was a 2 story 10k tank you would use to store rain water but built inside, it has since sized down to this. Tons of people build tanks of this size for indoor koi ponds, we do have in floor drains near this area. The 3/4 internal poly iso, R5? , was...

    North east USA, I can ship but buyer pays shipping.
  • Post in thread: Two MN200 classics with breakers

    $1200 can take it all. I think the above without wires is 1500-1600 NIB.
  • Post in thread: How Often dO YoU Top Balance YoUr LFP BaNk?

    My batrium BMS resets my 100% SoC daily right now ... it is hooked up as a battery backup right now but every day at least once a day the battery is topped off and all cells go into bypass mode and the SoC is set to 100% ... So in some ways they are constantly top ballanced with this system :D
  • Post in thread: SOLVED: Batrium charging issue, seeking advice on debugging

    So far it is working better than before ... Key thing I see now is voltages ranging from 335-3.5 as it is top balancing with default ramped settings ... the requested Ah is only 6.0 as it thinks it is at 94% SOC ... when the voltage starts to bypass I think it drops to 0.6Ah ... first time...
  • Post in thread: Batrium SMA Sunny Island Integration issue?

    Had the relay trip while I was in the room so I pulled the short set of logs (as they are easier to manage) and looked at them. Don't see any errors (35A) being thrown ... only active warning (which is always there) is that the temp sensor isn't connected on the SMA SI (why have that if you...
