  • Post in thread: To set up your main refrigerator as your diversion load

    OK 11 months later... I learned that sump pump (20+ AMP) surge COMBINED with refrigerator compressor startup is a little too much for the Trace SW4024 (tripped overcurrent). No harm done though. I now believe it is possible for lightening to strike twice in the same spot though, because they...

  • Post in thread: Temp sensor and NiCad vs Lead setting for LifPo4 with Trace SW4024

    These are the settings I am using with LiFePO4 from Power Queen- its a 2x12v = 24 volt setup, hence the x2 settings on the chart. the SW4024 DOES NOT remember the settings when you disconnect it from the batteries, or when you trip a fuse/breaker. So I keep these handy. ALSO the trace tech told...
  • Post in thread: solar panel individual voltage ratings for 24v system question

    a guy who has to ask the question (me) also hasn't likely memorized MPPT or whatever and to me voc is volotile organic compounds and so forgive that area of ignorance. But what I really want to know is;" If I grid charge at float or bulk voltages , then for solar charging does it make sense to...
  • Post in thread: solar panel individual voltage ratings for 24v system question

    I want to group some single panels elsewhere in the sun path so paralell so that each one can contribute when "lit" without pulling bank down when shaded.
  • Post in thread: another Epever charge controller setting thread BUT about using flooded settings group for LifePo4

    update. cable arrived can't get port to show in win 10. Plus the Controller does not seem to reckognise the panels even in stand alone. is there a hard reset? Many of us could have made a career out of writing better manuals.
  • Post in thread: Switching to Lithium with 29 year old Trace/Xantrex/Hybrid system

    Hi all. New here but not new. Am changing out old lead acid to lithium iron phosphate. Spoke to Xantrex, read info online from links at this forum, my plan seems to look right, so now am here to ask the guys who use this stuff. My question is, based upon using an existing older Trace/Xantrex...
  • Post in thread: an Alternative series parallel layout question for 8 batteries - opinions asked

    I don’t know theoretically it sounds right but again I should see if that picture A configuration is specific to the BMS of the batteries I kind of doubt it but I should check
  • Post in thread: iSTA BREEZE or TUMO? Turbine question

    We use panels-need a night time trickle extra for winter, no rivers so its wind.... they have a money back and it looks like what they build now is pretty well engineered, however an actual review like yours carries weight. I remember when "panasonic" came out in the 70's. real junk electronics...
  • Post in thread: Top Balancing "How to"

    very nice pdf thanks. Am compiling a solar home operator's manual for this home for the next generation and this will go in the toolkit. I use a smaller charger (it's what I have), and if I overshoot i use a cheap alligator clip modified sine wave inverter and a space heater to quickly pull down...

    thanks! I have a decent rapparte with a LifePo4 factory sales rep and will ask about jumpering the BMS; if I can get them to discuss it....

  • Post in thread: Can anyone help w/troubleshooting overcurrent error message?

    I am thinking along those lines as well, RC., the circuits are the same ones we have been using though, so possibly a sump pump motor is starting to act up and draw tons on startup, .... byut, the system has supported the same loads including (happily) a 1/2 HP AC sump pump that runs every...

    audible sound yes the rest no. will be trying machine 3 later might video everyting from install software onward for perusal/review. Will read the article thanks
  • Post in thread: CAN I passive balance 5S2P? do I need multiple balancers?

    Hi. Tired of manual balancing last time I looked (2022) I didn't find a passive balancer for my battery configuration. Is anyone aware of a solution? It's like this illustration but with five 12V per bank not four. THANKS
  • Post in thread: solar panel individual voltage ratings for 24v system question

    thanks. I'm at 800w panels ish so still have a sliver before changing controllers. Adding 2 150-175 watt panels should be pretty simple and take me to the max. Then I have to tie back in a pair of air 403's, so at that point the C40 can be used with them and I'll get a new charge controller for...

    Gotcha thanks
  • Post in thread: Trace Xantrex SW4024 Tricking search mode with led and low loads can there be a false or dummy load to activate the search on the inverter?

    HI. We have a trace SW4024. 1-One feature is a search mode where the inverter , instead of being on. is idling, looking for reasons to be on, and sends out a tiny search pulse looking for a load request (my own lingo sorry). When you switch on a light it knows and quickly inverts. This method...
  • Post in thread: Advice for a new system 600kWh/month system $20-30k budget.

    I would suggest you anticipate the labor to be more or harder than expected. The thick wires are WAY WAY harder to deal with, and good system design is far less forgiving than grid AC . I have "traditional" wired many homes, and wired in many service panels. Installing the system this year was...
  • Post in thread: New warranty battery into 1 year old bank? help

    Hi All! Last week during manual balance I discovered that one of our LifePo4 (?) will only charge to 12.9V. ( I’ll bet it’s a bad bms) The factory has been good enough to send a replacement (hats off to Power Queen for painless support). We all have been taught that batteries should be similar...
  • Post in thread: What are snail trails and are they bad for used panel buyers?

    What are snail trails and are they bad for used panel buyers? I am looking at some used panels which have them. A wholesaler in Arizona.
  • Post in thread: Top balancing with BMS and invertor - any issues to expect?

    I mentioned elsewhere but i use a cheap modified sine wave inverter with alligator clips and a small space heater plugged into that. It pulls the hot one down fairly quick, when its balance day (tomorrow- yuck)
  • Post in thread: Topping off or balancing a set of LiFeP04 batteries?

    Hi. A- can you really drain a battery that's still in the bank/pack? electrically how does that work? I have been un bolting on balance day (quarterly)k
  • Post in thread: EMP Protection

    So this is what I sent to our battery supplier "Hello... ...we are assessing the general system weaknesses in the solar energy systems of homes we design, and we are developing different protocalls. The subject of CME, lightening and EMP damage has been presented. We would like to have some...
  • Post in thread: Solar system with wind with sol ark12k and tess electric lithuim batteries

    Well th OP must be innoculated or something.. I'll jump in too. Looking at istabreeze 1500w. Currently have 2 Air 403's (Simolar to Primus Air 40). 1- Don't assume that when you have no sun you'll have plenty of wind. SOOOOO TRUE 2- Not only is wind unreliable but wind turbines in general tend...

  • Post in thread: Sump pump soft start question

    intriguing. In my traditional building trades experience sump pumps worth risking your basement on are in the 225.00+ range (2023 dollars). i could use one as our primary and leave the older less efficient one near the top of the crock as an always-on backup. The Zoellers' pump so fast there...
  • Post in thread: CAN I passive balance 5S2P? do I need multiple balancers?

    Ok. This configuration was setup 18 months ago as a 4x2 unit. A month later we added one more battery to each bank. 5 is max recommended for balance reasons (in some circles). System has been very good. Sometime this spring they seemed "off" so I began a manual balance (I do every 6 mos), and...
