  • Post in thread: 240v inverters and ground-neutral bonding?

    I've gone ahead and setup a N-G inline with a RCD (safety switch) breaker I setup for the output line of the inverter and it's appears to have 'fixed' the AC plug error and I get 'all good' LED indicators. For all outputs. This is an AU model of a 240v inverter, to which most US based...
  • Post in thread: I have an inverter without a grounding point, how do I ground it?

    Yeah, supposedly the ground is the output for the AC outputs and I ground via connecting to the ground/earth of that connection. Yeah, this is what I've done for my shed, off-grid, setup. I have a earthing rod in the ground and an earthing wire from that to the busbar in my shed fuse box...
  • Post in thread: 240v inverters and ground-neutral bonding?

    I understand basic DC and AC (240v) principals, but within the off-grid setup I have I'm having some questions on how I setup a 'safe' system. I've installed an array, solar charge controller, battery and inverter (240v) AU. I've also installed a grounding rod and have the solar charge...
  • Post in thread: Growatt SPF 3000TL HVM-48 can it run without battery to load?

    Growatt SPF 2000-5000TL HVM - spec's here. I was looking at the 24V system but want to run the max voltage for a limited number panels (only room for 3 panels), now I've seen plenty of videos for the LVM (120v) systems but not any (in English) for the HVM models. Now I want to setup my shed...
  • Post in thread: Growatt SPF 3000TL HVM-48 can it run without battery to load?

    It's certainly something I hadn't thought about in my setup, that it wouldn't work at all with no battery. So you've helped with that planning, and I'll just need to see how I go with how low it can go to ensure it has enough left to start the next day, irrespective of the season.
  • Post in thread: Switchbox/Transfer box question....(Need a pro / smart wiring guy!!)

    I've not used the manual one in a BOX, but the automatic I've inserted into a small breaker box with a common rail and N/E busbars. They don't have local boxes that fit either one and I had to cut some of the enclosure to fit the automatic one. The manual one is even more bulky, so that'll be...
  • Post in thread: I have an inverter without a grounding point, how do I ground it?

    It's a totally new PV/DC fuse box created just for this shed, and has only 3 connections on the ground busbar. The PV array, I've run a earth wire from each panel (3 panels) in series back to the busbar, I have the charge controller connected to the same busbar, I have (I think) the ground from...
  • Post in thread: Charge controller (ePever) settings and battery SOC missmatch (Voltx 48v) help?

    Thanks for that, I'll take a look. Not sure of the big difference between 12v 200ah you're running and 48v 100ah I'm running. I've found the extrapolation from 12v to 48v can result in some wide differences. Great resouce, the spreadsheet and setting explainations + notes!
  • Post in thread: I hate BLUETTI AC200 provided whimpy solar cable. So I made my own…

    Question, with the two piece adaptors, with the 'aviation' to XT90 then XT90 to MC4 for a connection from a solar array to the Bluetti unit. Is there much benefit, at all, from creating a 'aviation' to MC4 cable and the solar array going in directly? I'm running a 30m 6mm cable from my array...
  • Post in thread: Growatt SPF 3000TL HVM-48 can it run without battery to load?

    Thanks for the response. So you have the same model, the SPF xxxxTL HVM? Next question, with the battery connected will exessive solar be first used by a load if the battery is full? Or does it need to charge/draw from the battery at all times? Will it use solar first and then battery?
  • Post in thread: epever cloud cant create account????????

    I had to contact my WiFi adapter seller, who then contacted ePever who then created an account with a generic password. Then I was able to access, but it took months to get a response and then weeks to get an account.
  • Post in thread: Charge controller (ePever) settings and battery SOC missmatch (Voltx 48v) help?

    The Voltx has it's own built in battery monitor, so a 3rd party shunt would be more accurate than that built in monitor, if it's voltage based monitor? But as the charge controller is pushing out a higher voltage during charge it'll not be accurate. So that's where, I'll assume, the over...
  • Post in thread: KRXNY 48v 3000W DC to AC 240v inverter, no earth?

    I recently purchased this inverter KRXNY 3000W Pure Sine Inteverter, and I've found it doesn't appear to have any earthing point. I have setup earth for my off-grid setup and have earth to a common busbar that connects the panels and solar charger, but assumed the inverter would require an...
  • Post in thread: Charge controller (ePever) settings and battery SOC missmatch (Voltx 48v) help?

    I've recently gotten a ePever Tracer5420AN charge controller and a 48V Voltx 100ah (SH48-100+LCD) battery, for my solar array (3 x 350W). The charge controller had 12V @ 25c settings defined in it's manual for Lithium batteries, to which I multiplied by 4 to get the values for 48V system. But...
  • Post in thread: epever cloud cant create account????????

    Same issue, and I tried to contact via support. No response yet.
  • Post in thread: Shed system with only 3 panels, 24v or 48v battery possible + cable sizing?

    Hi, new to the DYI 'offgrid' scene and watching so many videos and tutorials. But still not 100% on a few things, or most likely a lot of things. I have 3 x 350w panels in series on my shed roof, which I'm using to charge my Bluetti AC300MAX (2048Wh) + B300 (3072Wh) backup batteries. But I'm...
  • Post in thread: I have an inverter without a grounding point, how do I ground it?

    I've purchased an inverter that doesn't appear to have any external manufacturer ground point, even though it has an AU plug and includes (from appearance) live, neutral and earth connections for an AC output. I've got a common ground in my fuse box, which I have my PV panels and charge...
  • Post in thread: Shed system with only 3 panels, 24v or 48v battery possible + cable sizing?

    Thanks for the response. I live in Melbourne, Australia, so though we get some cold Winters rarely under 5c, but wouldn't say never. What are the affects I should be mindful of? Okay, I'll leave some headroom and go with the 200v then. I see in many videos larger cabling and reading guides...
  • Post in thread: epever cloud cant create account????????

    I've tried support, from various sites that ePever redirect too, but can't seem to get a response for creationg a cloud account. Does anyone have an email address they've successfully used or alternate method to get a cloud account created?
  • Post in thread: Shed system with only 3 panels, 24v or 48v battery possible + cable sizing?

    I guess even though the Voc of the array can not go over 150v, it's close and always better to have room for any issues. Thanks for that resource link, I think I had found it in the past and never understood it's impact on the setup. For the cabling, this is from the charge controller to the...
  • Post in thread: Charge controller (ePever) settings and battery SOC missmatch (Voltx 48v) help?

    I can do that, but in relation to the current settings and the 'Voltx' reconmend settings I'm not sure of all the equivilant changes I need to make or which ones lines up with the available options. As they appear to use slightly different terminology which look similar, but aren't. For...
  • Post in thread: Growatt SPF 3000TL HVM-48 can it run without battery to load?

    The LVM is the 120V version and HVM is the 240V version, from what I can tell. Looking at the video and your experience, under Solar + Battery mode, will it draw from the solar first and then from the battery as needed? Yeah, that the "ES" models I mentioned.
  • Post in thread: Growatt SPF 3000TL HVM-48 can it run without battery to load?

    Ah, I'm looking to have a 48V 100ah battery installed with this setup. But I guess the low voltage cutoff (DoD set high 20%+) once solar is gone, the next day it'll be important to ensure it has enough power left to start up the inverter just to receive solar input. The ES model this wouldn't...
  • Post in thread: All-in-one inverter for home network UPS replacement?

    As long as the device you're replacing the standalone UPS units for is rated as a UPS, then all should be fine. I have 5 UPS 1500va UPS units in my setup, but have the backup batteries feeding those UPS units and then that offers the dedicated hardware of the UPS and the power backup of...
  • Post in thread: .

    Short ans Yes, that should just work as expected. As long as you wire it correctly at the GFCI outlet. I know in certain regions that work is still meant to be done by a qualified electrician. But effectively it's the same as plugging a powerboard with a long extension, or am I missing what...
  • Post in thread: Switchbox/Transfer box question....(Need a pro / smart wiring guy!!)

    Would an Automatic Transfer switch be an option? Though the 20A might be a limiting factor on the type you can use.
  • Post in thread: Charge controller (ePever) settings and battery SOC missmatch (Voltx 48v) help?

    I think I've worded my question and/or thread wrong, as it seems none of the answers relate to the question I've asked regarding the 4 values supplied by the battery manafucturer in relation to the current USER settings of the charge controller. I'll see if I can think of another way to word it.
  • Post in thread: Charge controller (ePever) settings and battery SOC missmatch (Voltx 48v) help?

    No, these are the settings that Voltx suggested in their manual for setting your (my) charge controller to. To ensure/avoid the batteries BMS is engaged and the controller is engaged before the BMS, thus protecting battery and BMS (the more costly of the hardware in the system).
  • Post in thread: epever cloud cant create account????????

    How did you achieve this? What method did you use? I'm trying via the app, still nothing.
  • Post in thread: Switchbox/Transfer box question....(Need a pro / smart wiring guy!!)

    There are manual options for Transfer switches. I use one in my breaker box, for GRID and backup battery operations. But I also use an automatic transfer switch for my server room power option between GRID and my backup battery solution. Like this...
