  • Post in thread: Recommendations for stackable inverters with WIFI

    Yes thats a good point. Thats one thing I have liked about Midnite solar is they have had the same controllers for years. They have the 5 year warranty and you can send it for service and add 2 more years. I had one fail and they replced fast and easy.
  • Post in thread: Preparing for the heat...

    Again nothing wrong. all day nice and cool. Im off grid so for 12-14 hours no AC. Different story if I had AC all night but that really cuts into the batteries. 6pm here is hot and humidity does make a difference even for batteries. All day I have 5 to 6 AC units running so the inverters are...
  • Post in thread: Wiring for East / West Solar array

    From what I understand this is how the parallel/series combination will work. East config 3 panles in series 1st string 3 more panels series 2nd string Combine 1st & 2nd strings in parallel West 3 panles in series 1ststring 3 more panels series 2nd string Combine 1st & 2nd strings in...
  • Post in thread: Wiring for East / West Solar array

    Yes all exact the same. I will try and track how much longer I can not dip into the batteries. Panels are cheap and last forever. If it works I might double up. Midnite solar has a nice desktop app and can see good history on a good visual chart.
  • Post in thread: Off grid completely

    Pretty wild isn't it. I look at the solar panles on half my roof and running 5 air conditioners, internet, tvs, big aquariums, and much more. All from the sun hitting one little spot. Elon musk said only need 100 miles x 100 miles in nevada to power all of USA. And 1 square mile of batteries...
  • Post in thread: Remote monitoring

    Yes for sure starlink will work. I have a router pluged into the starlink. You use the mymidnite2.com do view all your classics. I can see all 4 of mine. Look on you tube Midnite has great how to videos
  • Post in thread: Any news on THE ONE? Is it the one for me?

    I have been a huge fan of Midnite solar. I got the hawks bay and now regret it. I have been waiting a year just to get a web access. im switching to EG4 600xp. ive been holding out for a newer version of 6000xp. maybe with a display like the 18k . But for the price I will get 3 of the 6000xp.
  • Post in thread: Any news on THE ONE? Is it the one for me?

    No major problem other than no web support or phone app. I like that it is 600v input. Price is kind of issue too. 2 or 3 6000xp seems the way to go.
  • Post in thread: Recommendations to monitor individual batteries on my 90 kWh AGM Battery Bank

    I looked that up and over my head haha. HAve any link or video how to set one up for 24 batteries?
  • Post in thread: BMS Recommendations, to monitor 24s via wifi?

    Im a BMS newbie so need some help here. I have 24 large 2volt AGM batteries. Looking for a plug and play system to Monitor voltage to each cell. Looking for Wifi so I can view on my PC remotely. Also log history is important. They batteries are old and some are going bad. If I can watch the...
  • Post in thread: Recommendations to monitor individual batteries on my 90 kWh AGM Battery Bank

    I looked them up and might work. I will message them to see what they recommend. I like the widi part and PC monitor Do you have one? Can you data log? I think it can help me spot bad cells. Tricky to spot bad cells some times.
  • Post in thread: Recommendations to monitor individual batteries on my 90 kWh AGM Battery Bank

    Do you have one? What is the max AMP at 2.3 volts? I can get them all full with my solar panles easy. I would try to pick one with lowest voltage and see if I can bring it up to the same as others.
  • Post in thread: Recommendations to monitor individual batteries on my 90 kWh AGM Battery Bank

    Can you recommend a brand or microprocessor that can monitor 24 cells via wifi?
  • Post in thread: Recommendations for stackable inverters with WIFI

    Yes thats what I think also. 3 units would handle 15k if I was down on power we could not run as much AC. Thats why I like stackable. I know my controller and inverter both get hot. Wonder how a all in one like growatt how hot they get. Growatt says 5 year warranty. Wonder if it it holds up or...
  • Post in thread: Wiring for East / West Solar array

    Day time I have a 100 panels flat so getting batteries full is no problem. I want max out sunrise and sunset because its so hot here we need Air Condition 24/7 in the summer. My question is how the panles are wired. I have 12 panles to work with. 6 east and 6 west. For voltage I put three in...
  • Post in thread: Wiring for East / West Solar array

    And the strings can be in series correct?
  • Post in thread: Recommendations for stackable inverters with WIFI

    Looking for recommendations for stackable inverters. about 5000 to 6000 watts each. 2 maybe 3 units. In the summer I have 5 ac units running on a off grid home. But winter I dont consume much at all. Dont really want a controller built in. Looking for somthing with long warranty.
  • Post in thread: Wiring for East / West Solar array

    Yes thats what thought also. Its a combination of Series and Parallel That's incorrect information I think?
  • Post in thread: BMS Recommendations, to monitor 24s via wifi?

    What's wrong with BMS to only view voltage? Charger and balancer can be turned off. I looked at that victron and I would have to buy 24 of them. Also prob wont work down to 1.75volts. Daly 24s BMS is only 100bucks or so. Not sure how it stores data per cell. I would love to see a chart with...
  • Post in thread: Picking brains...help with Engine swap to electric...32ft Cabin Cruiser

    I really love this concept. so many redundancy. Even regenerate when sailing. Perhaps this is the future is hybrid. You have 2 generators or two direct drive motors. Or sails, or solar or even charge when sailing with regen. Wow im sold haha. This boat has two but I think one would still work...
  • Post in thread: Unique propane refrigerator - on A/C

    Most efficient way is take a chest freezer and use a inkbird temp controller and set it to 35deg. Cold air stays in even when you open the door. Then I use another chest freezer and set it coldest but have it shut off from 1am to 6am when I am on batteries.
  • Post in thread: EG4 6000XP with SOK 48V 100Ah PRO VS EG4 LL

    If EG4 cells were not welded I would buy them. Only thing that draws me to SOK is if I have a bad cell I can swap it easy. All components are easy to swap on those. on the EG4 LL what would it take to change a cell? 5 to 10 years down the road maybe some cells might have issues.
  • Post in thread: Best solar panel angle for east/west to maximize Sunrise to Sunset

    I am actually near San Felipe Baja California. 30.751119, -114.696263 or https://goo.gl/maps/qZ3f9Cwe5GuAKZPJA Did a quick test yesterday with one panel. I was told I could connect neg and pos from the panel. I then put a clamp meter. Noon with a panel flat perpendicular to the sun was...
  • Post in thread: EG4 6000XP MPPT Questions

    Would this still be fine? Extreme scenario could one aray face East on one MPPT and the other face West on second MPPT? S Below is what the manual says. When sizing strings for each MPPT, they MUST be the same model, brand and # per string(series and parallel).All panels on a series/parallel...
  • Post in thread: Best solar panel angle for east/west to maximize Sunrise to Sunset

    Have you tested it? If one day you only charged from the west and the other day only east? If it adds up to the same.
  • Post in thread: Preparing for the heat...

    Some tips from what I have leaned. I have a large off grid system. Each day we get close to 100deg but its also humid sometimes 70-80%. I insulated a battery room and also wanted to cool the inverters, batteries and controllers. Heat is bad not only for batteries but also electronics. All that...
  • Post in thread: Unique propane refrigerator - on A/C

    If power is a issue and you want to get more efficient you can remove the exterior of the fridge and expose the wires and get away from freezer then even add more foam. I would be couriuo s to see before and after efficiency on a mod like this.
  • Post in thread: Can someone with a DALY Smart BMS help me out.

    If anyone has a 24S 72V BMS can you tell me if it will power on with only 48v? I have 24 batteries 2V. ITs a 48V system. I only want to monitor voltage using the Daly BMS. My voltage range is 2.25v to 2.35v. I dont plan on charging at all for now. If it can charge thats a plus. Im just...
  • Post in thread: Does Server Rack Battery Orientation Affect Built-In DC Breaker Arc Quenching Ability?

    I live in a hot climate and when I had smaller AGm batteries I put in a chest chest freezer cracked open on a controller set to 77deg worked well. Thinking about doing the same with server rack batteries. Wonder if they were in a special rack mounted good if they could be stood up in their...
