OK, so I'm down to wiring my 2000w scenario. A DC +40' run from panels is not looking good as it seems due to lost power at this length. Would it be best to station batts and inverter closer to the panels and run AC from the inverter to power source of about 30' from source? For clarity...is it...

Thanks again for the help! The charts you use are very nice. Are they part of a software program?

Thanks for all the replies...this is a great forum! Got a better handle on how these panels hook up now so as not to fry my SCC. Decided to just go ahead and max this setup out and do a 5S4P at 2000w since I already have this inverter. Do I use 10 awg wire for the 1 to 4 branch connector and...

Oh man... I have a lot more to learn before plugging in ugh!!! HELP...lololol

Wait...was that meant to be hot weather?

Thx for that easy to understand reply!

This will be mostly used in the PNW. Mount would be similar to your avatar yet in a separate array will mount on top of an RV.

I finally got most components delivered for my 24v Sinopoly LifePO4 200ah. Pretty much just need the wiring now. I'm using a Victron SmartSolar Charge Controller (150V 70A Tr). Can anyone smarter than me, which would be most of you, tell me the best configuration for panel array consisting of...

Hello Will...First off I never laid claim that float charging LFP will cause fire. My reply to offgriddle clearly stated "possibly" due to so much info on the web projecting all kinds of differing opinions in this regard. Yes, I have already seen the Relion PDF claim you posted soon after my...

You might want to research the links I gave in reply to azgrogg as it appears you are trickle charging your LFP batteries. This will put them in an over charge condition and lessen their cycle time. And quite possibly cause a fire.

Ok, after some extensive research I've found some better info than "hand wringing" here... https://marinehowto.com/lifepo4-batteries-on-boats/ It appears these folks are not your typical DIY types as their testing lab is pretty decent and quite knowledgable. This website is a very long read and...

Yes, I see that...many available. Yet I see none that are programmable to cut off at a specific voltage. All the 24v chargers I've seen will keep a 100% SOC.

I'm only going by research showing anywhere from 40%-60% SOC as being ideal for storage regarding longevity for these batteries. Not only that, if it could charge 12v also then I would have a backup charger for my 12v batts.

I saw that one but it's not for lithium. Thx for the link though!

Wouldn't that somewhat control the SOC as shown in this pic from one of Will's tutorials? Oddly enough, all eight of my batts were delivered at 3.10v exactly.

OK, let me ask a different way... Is there a 24v battery charger with adjustable output voltage that anyone here knows of?

Thanks for the reply. But that charger is for 12v up to 85ah. Mine is 24v 200ah bank. And it's not clear to me how this would be able to maintain ~50% SOC. Seems to me it would need to be programmable regarding voltage output like a charge controller. I'm total newb to this is why I'm here asking.

I've done quite a bit of research on storing LFPs and the general consensus is to store them at ~50% SOC. Not saying you're wrong but rather my research shows otherwise on a grand scale. Can you link me to info supporting your statement? I only ask due to the cost of these little marvels.

I'm putting together a 24v off-grid LiFePO4 setup as seen here. This will be used for camping so a lot of not-in-use time will be involved. It seems these batteries do better at ~50% SOC for storage purposes. Are there on-grid battery chargers available that can maintain this SOC while this...
