I have a 24V 3000W inverter. All in ones I'm gonna get are both 3000W, just 48v vs 24v. I have 1100W of panels on roof. The all in ones are: 3000W 24V $675 3000W 48V $675 If the 48V was more expensive, I'd go with 24V, but same price. So I thought why not save on wiring anyways, and go 48v...

So 2/0 would be fine to use for my purposes? Between batteries, battery bank to lynx distributor, and lynx distributor to panel? Battery bank fuse = 200A, 225A, or 250A? 225A I'm leaning towards as middle ground. Mrbf bolt on ok to use, but T class is preferred as best thing on forums. Mrbf...

manual says can run up to 4 in series or 4 in parallel (16 total), but who knows. Thought parallel batteries don't balance well? Series doesn't balance well either? How to mitigate balance issues? At 24v 2s2p, would I run into balancing problems? Better to stick with 24V to eliminate...

What do you mean by 48v same range will be difficult?

Guess I'll keep my 712 then. Thoughts on single server rack vs 4 batteries?

I'll be using battery balancer. And yes, losing 1 battery, I meant I could potentially finnagle something for 24v or 12v, still have some sort of power, but moreso, I'd just repair it or replace and get 48V system up and running vs a macgyver situation with 1-3 batteries which can't run my aio...

Looking to potentially buy EG4 3000 EHV-48 all in one. Does fan run constantly? Even with no loads? I've heard the fan runs constantly vs only on when it heats up from loads and needs to cool down. Anyone confirm this? How loud are inverter and charge controller fans? It will be in skoolie...

How loud are fans when idling? Would sleep be disturbed sleeping in back 20ft away? Would it drive me crazy and unable to think if I'm sitting near it?

I have 4 x 12V 100Ah LiFePo4 batteries. Wired in series for 24V 200Ah. Batteries have 100A/1C discharge rate (LiTime brand). So my breaker/shut off switch should be DC rated at 250A or 225A correct? 200 x 1.25 to allow for safety margin puts me around 250A, but 225A might be better due to lower...

When sizing wire between batteries, fuses, inverter, bus bar, breaker box/fuses, etc. My set up: Panels: 1100W panels (6 x 185W) CC: 60A Battery system: 24V, 4800Wh, 12V x 4 @ 100Ah each, LiFePo4, 2s2p Inverter: 3000W 24V When is the wire too big? When does upsizing become pointless...

Inverter fan keeps running constantly. Just started doing this yesterday. Zero loads being pulled thru inverter. Wired-in remote installed on wall panel doesn't turn it off anymore like before. It doesn't respond at all. When I turn remote on/off, inverter fan slows slightly upon power on, and...

Thanks

Any problems with 36V panels charging 48V/60V system? Will be series connected up to 216V, so assuming doesn't matter. Will I have to wait longer in the day, when better sunshine achieved, till panels start pulling panel V closer to battery bank V of 57.6V and then starting to charge bank? 57.6V...

So, that's NEC Table 310.15(B)(16) (Formerly 310.16) that you screenshotted states: "Allowable ampacities of insulated copper conductors rated up to and including 2000 Volts, 60°C through 90°C (140°F through 194°F), Not more than three current-carrying conductors in raceway, cable, or earth...

According to what chart? Everything I've seen is over 200A. Blue sea Systems circuit wizard says 2/0 rated up to 285A, the colored chart Blue Sea uses and in Will videos says 2/0 good for 200A out to 20ft round trip, but perhaps my settings are wrong? 24V, 200A, 6ft round trip run (closer to 4ft...

Should be. For a skoolie system. I'm going to use a 24V to 12V step down converter for 12V DC loads (water pump, suburban propane furnace, 6gal water heater, maybe a roof fan). Is that what you meant?

I have 4 batteries, 2s2p. So that's 12V @ 400Ah, originally, and when in series is 24V @ 200Ah. I'm not sure what you mean. Bear with me please haha

But wire and fuse off battery bank should be sized and fused for 200+A, correct? Bigger wires and fuse and cut off switch pre-Lynx (from battery bank), and smaller wire and fuse (already in Lynx distributor) post-lynx (to inverter)? And again, separate fuse (mega fuse in lynx distributor) for...

I have: -skoolie build -24V system -batteries: 4 x 12V 100Ah Amperetime lifepo4 batteries (5000Wh battery capacity) -panels: 1100W --- 6 x 185W 36V 5A panels ~1100W (either 3s2p @ 108V 10A or 2s3p @ 72V 15A) -gifted 30A 48V to 12V buck converter (with inline fuse) -also have 40A 24V-12V, but can...

I've got: -Eg4-3000EHV-48 all in one -4800Wh battery storage (4 x 12V @ 100Ah lithium from LiTime) -1100W solar: 6 x 185W, going all series for ~ 220V PV input -Victron lynx distributor -Victron BMV-712 smart shunt I'm going up to 48V system @ 100Ah with 4 x lithium batteries in series...

How often would I have to balance the batteries? Is there a way to wire so that I don't have to remove all batteries, physically, and charge each one up till balanced? It's just me and my skoolie, no other power sources around so I can't just pull batteries and take to my garage/house and charge...

What's good brand balancer to use? Preferably 1 unit that does all 4 @ 48V simultaneously vs 4 units 4 x 12V.
