I may be totally wrong and I hope someone will correct me if I am. But, wouldn’t say a fifteen amp charger putting out 14.4 volts at 95% efficiency be 15x14.4=216 x1.05= 227 watt draw? I If I’m right, now you can get some charging done! VictronConnect has some nice little Bluetooth...

Yep

What load is on when you see this drop?

Not near enough info to help you. We need more.

I have no idea but would be possible or helpful to connect your plus and minus "diagonally to your train of lynx's and shunt?

Cannot answer to series, but have five in parallel with no issues

Sorry Bro, you’re not going to trick me into that a second time. Ima gonna tell Dad 🤤

12V. The Dometic used 13 watts continuously to keep its brain alive. The Nova Kool uses 46 watts when running but at about 40% duty cycle that’s about 19 watts/hour. That’s up not down right? But that’s not all, my RV had an electronic control valve to keep the propane on that used 24...

So I think that most to this section are RV based Solar enthusiasts. What else other than your RV travels does your investment In Solar do for you? Mine? Powers our second refrigerator 24/7/365 A cord to the garage to charge e-bikes and power small tools what else?

I replaced a 6.5’ Dometic propane with a 9.2’ compressor Nova Kool in the same opening. My energy usage went down!

Don’t forget that Fed land is YOUR land . And MINE too. Don’t fuck it up The Feds don’t, WE do

Where are you located for that shipping cost?

Thanks. I’m pretty good on this one. I’m a bit of a nut on strain relief and cable retention. What else?

That is how I would describe it too, but what conditions would make it blow? What would have to happen to create that short?

OK, but what else does the class protect against? what else would make it blow?

OK , I‘m a dummy so tread lightly. I have a 600AH battery pack and a 2000 watt inverter. 250 A class t fuse and all wiring should handle 300A plus. So unless I manage to somehow pull beyond 250A for some period of time, I should be covered? But. . . What else is this class T fuse protecting...

Try West Marine https://www.westmarine.com/ancor-flat-duplex-wire-by-the-foot-P009_274_003_002.html Stranded tinned copper I wouldn’t use Romex in an environment that would see vibration.. it can work harden and fail

Victron recommends 220w max on the 75/15 and 440w mX on the 100/30. I have three of the 75/15 running 200w each and one 100/30 running 400w. Everything runs great

I’m going to suggest that you buy your battery last. Things are changing rapidly. Build your battery box to handle an 8D battery size or 3-4 of the BB-LiTime.. that would give you 300-500 amp hours of storage. Plenty for a van. I had 220AH of AGM in my Sprinter and was able to make it work . I...

One more thing about running on propane. My RV had a solenoid that consumed 24watts continuous to hold the valve open. Between that and the brain, it used more power than my compressor fridge does

And even on propane they still use some 12v to keep their brain alive

Your longest, most often running, load Your biggest load though briefly running. Get a handle on those

The charts above show the flat area width and thickness are the same for the two hole sizes

As to panels, don’t just buy the biggest you see. Play a game of Tetris on your roof and you may find you can get more watts by using more small panels than large panels. My 2000 watt xanttex inverter runs my 1800 watt induction cooktop just fine. Micro too just not at the same time. Only...

This might be a good thread to ask my question. I originally built my RV system as a novice. 3 battle horns and 2000watt inverter. 250A ANL fuse. Learning more over time, I see I should have gone Class T. I added 3 more batteries but no more load, just more storage. With my new (internet)...

One thing I would add is to make sure you don’t buy something that is odd size/voltage/wattage in case a panel gets damaged and needs to be replaced

Or a “what oil to use” on a BMW motorcycle forum ? Don’t ask me how I know. For Fu’ks sake, just make sure there is oil in it

Also, what settings do you have the SCC set for?

I guess’s no one including myself who replied to thi thread really addressed your real question about one battery or two? ONE!,, always build the biggest battery you can to account for a possible high load. my six 100 AhH LiFeP04 are in 3P2P configuration. Each 3P have their own disconnect...

This. It is all just pretty much basic math. Do an energy audit of the equipment you want to run And the length of time it needs to run. Then this will give you how much energy storage you need. Then this will tell you how much energy generation (solar or genset) you need to replace what you...

Thanks guys. So I guess i jump to a 150/? SCC?

I know you should not over volt a charge controller. The panels I am looking at have voltage ratings of 30.7 Vmp and a voc of 37.8. . I’m thinking I should not run three of these on a 100v charge controller. Absolute low temp could be 20* F. Input?

I completely agree with Rocket and suggestion edit: I recommend Bay Marine Supply .com for your Victron gear if you don,t have someone local

If Your needs are actually 50 A, your batteries have less than one hour of storage. Then , your solar can put only put 1/3 of that back in the.next day. you are asking too much from too little

And still, no battery specs
