My Pip-LV2424 MSD says in the manual it is 125mm x 300mm x 440mm. It says allow clearance of 20mm to each side and 50mm to the top and bottom. Im not sure what the difference in your description is between the "box" and the "unit". The metal box that contains the guts of this lv2424 is what im...

Dont see why you cant use 4 panels 2s2p for (98v x21a = ~2058w)

The time it got to 21.5, it was charged by ac utility company power, which as I said before charges at the maximum 40a or whatever I set the max too. So it was not a helpful example of solar max current. Last month my battery bank got as low as 25.4v and the solar charging current did not get...

I will give that a try. As noted before, Ive set float as high as 27.8 to see what happens. It is now currently off grid, but when i had the unit hooked up to utility company power, I used that 27.8v over night, when I turned off utility power, it settled to 27.11v. I had a 100w freezer as a...

Is the 104v open circuit on your voltmeter or is that on the LV2424 display? My 240 panels, 3 in series, put out 104v on voltmeter open circuit, but on 2424 display the range from 80 -90. The range listed in the manual is 30-80v. And yes, Max limit listed, prior to moment of damage is 145v.

I apologize for not explaining my settings and experience more thoroughly. Using your example, Were I able to charge up to and stay at 26.9, what you are appearing to convey as a sub optimal SOC after a night of dropping, I would be satisfied. My bank has yet to charge up to 26.9 and upon...

I may try something like this, but according to my battery specs, 60a would be pushing it. So I may try 40a util and 60a combined (max). My current utility charge and max charge are set to 40a. When I use generator i get the full 40a

Source priority = SOL Max charging current = 40a AC input = apl Power saving = sds Battery type = Use Auto restart on overload= ltd " " on over temp = ttd output voltage = 120 " frequency = 60 Max Utility charging current = 40a Setting voltage point back to utility source when selecting sbu or...

Thanks for taking the time to respond. I’m still confused about my manual and what this 30v-80v term means. I hope it didn’t seem like I was suggesting it was an optimum range. I still remain ignorant about what that range is. Thanks again

Im trying to figure out the meaning of "PV Array MPPT voltage range". In my manual for my LV 2424 msd it says "30~80vdc". The 30 is normal type font and the 80vdc is grey font for some reason. It says "Maximum PV Array Open circuit voltage" is 145v. My Solar panel array shows 104v open circuit...

Im following this thread as Im experiencing similar MPP 2424 issues. I have 6 240w 3s2p panels and expecting close to 1440w in full sun, Im getting on average about 250w off peak hours and at most 650w at full peak. Each 3 panel serial array puts out 104v open circuit using voltmeter. MPP...

Good Read. Although I learned some things, it convinced me to cancel my plans until I can better understand these concepts. Thanks

I am planning to create a 9 panel array and I have either 30A or 100A circuit breaker I had planned on using near the SCC to protect it from Array. Using 10 awg copper wiring throughout the solar arrays to the SCC. The panels are each 240w, 37.2v VOC, 8.37A ISC Fuse rating 15A. I planned on a...

Wow, what a great pdf explainer for overpaneling. I appreciate your reassurances. I'm not an electrician and I was about to cancel all of my projects for fear I was going to injure my family or worse. I'm printing this document and putting it in my binder. Thank you

Sorry again, as a noob, Im either not following you or Ive been wrong all along, which is very often the case. I was not aware that using different arrays of different voltages would automatically set your system on fire and destroy your controller. I was under the impression that disparate amps...

Im a noob here, so Im curious about your remarks about "Overpaneling". Taking for example a 3s3p setup of these panels, I was under the apparently mistaken impression that you could use 9 panels in this setup. Why is 6 panels at a time the maximum? I was under the impression that based on his...

I got a 24 to 13.8v step down buck charger, but had a problem when my 24v bank ran down & hit BMS cutoff the buck charger back fed 13.8v back to my lv2424 inverter charger causing a fault and hopefully no damage. Not sure if a diode or isolator would fix that and if so which one. Over and...

I might be mixing up terminology, but the BMS Discharge cutoff according to your pdf spec sheet says 330a at I think 16 ms,.... it also lists a max of 200a for 3 seconds and then the other 100a limit you mentioned. I also saw on the FB the SOK rep mention 130a. If I was to guess, and only a...

Sounds like your question is probably more focused on the battery side needs, but if you are interested, Here is what SOK told me they recommend for my 2424. Mind you, several of the settings are not available in the 2424: Over Voltage Disconnect 29.4 V Charging Limit Voltage 29.2 V Over...

I read Will's point as "What is your goal or motive in making daily decisions that improve your life and the well-being of your local or national community?... and what choices YOU make are more likely to have the intended outcome?" As I said, the above 22 yr old gentleman has adopted the...

When you see the label "Made in America" that designation only requires a certain portion is made in America. The converse is true as well, that many Toyotas and European cars are mostly made in America and even more within the auspice of the North American USMCA. This 22 year old is describing...

Any ideas Bud. If I'm not confident this setup is safe, I'm going to scrap it

Great points. Great video. We all make cost benefit analysis when we make economic decisions. This includes thinking through how our consumer choices benefit the ultimate manufacturer and or country. If we believe there is a benefit to our best interest, even if that means for our interest in...

Here is the thread from when I was formulating this setup.... https://diysolarforum.com/threads/new-24v-lithium-bank-system-cabin-separate-12v-genset-starter-battery.24894/

https://www.amazon.com/KNACRO-Vonverters-converts-inverters-Waterproof/dp/B0887VCCYP It didn't come with a spec sheet, but this is the product. Thanks for your response

I have a new LV2424-MSD 24v all-in-one inverter charge controller and after watching one of Will's videos about using a 24-12v step down for my 12v accessories, I decided to buy one. In addition to that, I wanted to use the step down to float charge the 12v lead acid starter battery for my...

$180 for kit. $40 for an rs232 cable. Subtle

So if you have 2s2p SOKs, you should be allowed 100amps charging, yes? (Btw, I recently heard from SOK that 50 is allowed but 40a is recommended)

Ive been confused about a lot of things before..... This is just one example from the MPP Solar website.... Bluetooth?

I'm seeing remarks in different places that say connect to your mpp device using Bluetooth or use the Android app to connect via Bluetooth,.... Bluetooth, Bluetooth! ...but no place that says if my lv2424 has built-in Bluetooth and if it does, why aren't there settings to turn it on/off and if...

Thank you for getting me on the right path

So at 13.8v it will float charge the lead acid but will never reach boost charge levels, right? But I thought a typical float charging charger hits a certain peak then drops volts to 13.8 or so but also drops amps down to a gentle "trickle", or maybe I'm assuming. For my application, I'm...

I am replacing my old 12v Lead acid system with 24v lithium and new MPP LV2424 inverter/cc, but need to keep one of my 12v Lead acid battery to start my generator and/or run a couple 12v items (10 amp pump, etc). Generator draws less than 10A to crank and has its own 10A fuse. I was looking at...
