Ok

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
