you always bond your neutral and grnd at main panel (or first disconnect from grid incoming) You do not bond in subpanels... why did you decide to remove the main panel bonding?

I went to MTU in hougton, mi about 40yrs ago and as I recall there was not much sun at all hehe

I have the lv2424 and it definitely does NOT bond N/G on battery....even tho they said it does; probably varies by model and they have only a single answer they give out ;-) when it comes to bonding you have to deal with a variety of situations: 1)plugged in, on grid: LNG are all present and...

yea, Michael B Caro scammed a lot of people here for many thousands of dollars. Not just bad cells shipped either, but taking money and never delivering ANYTHING. avoid him like the plague.

absoletey positively this.... you must measure because calling the manufacturer does not always result in the right answer in todays "special" tech support world... you can also easily do this by using a receptacle tester such as...

if you are not worried about microvolt errors just snag an AD584 voltage ref from ebay and that way you can have some degree of confidence in your meter. as mentioned above eevblog is a great source of info on the technical side of electronics when it comes to meters; here is an old multimeter...

step one...move to another state ; NOT california ;-)

well you just have to be curious as to what those cells "really" are hehe... could be a grade "A" cases with a AAA battery inside hehe

well, deciding to move to 24v or even 48v is almost always the right thing to do..that said... step number one is absolutely positively the most important...calculate what your actual power demands will be!! You really need to start with knowing what you plan on powering (everything) and how...

well, I chat with my jdb bms modules with python via serial all the time...so...it does work that way. just to make sure you have everything setup right with your software use serial connections directly first. Just get some usb-serial devices and plug in which should "prove" to you that your...

I just use a raspberry pi and usb-serial adapters for monitoring... its simple and reliable. I have the pi using 4 usb-serial adapters chatting to everything without an issues (well, ok there is one major challenge, trying to buy ftdi serial adapters that are not counterfeit!). For the software...

this is the fundamental issue that caught me and others... he ASSURED everyone that the money was in separate accounts and safe until product shipped...he absolutely, positively lied about this. This is not an issue of "got taken by surprise in world events of shipping/supply issues"...nope.. He...

just did a quick look at the website and it does "seem" to indicate that you can use the DC output while charging: "(only the DC ports support pass-through charging)" However!!! You will notice that the manual shows a DC output of 9-12V/10A; it also shows that the DC input charging (solar port)...

when it comes to batteries of the same chemistry, when you put them in PARALLEL you will get the sum of their AH ratings NOT the sum of the output current. for example: 2Ah battery in parallel with a 1AH battery will provide 3AH of "power" as they will both be at the same voltage (they are in...

everyone that lives on an island knows that shipping is VERY expensive...and in many cases shippers will not deliver to that address. You knew you lived on an island so the right way to give your address would have been, "I live in spain, ON AN ISLAND". You kept a very important part of your...
