Great video. I would've been afraid that the charge controllers would work against each other and back-feed power into one another, but then I realized that they can't because if they could the battery would back-feed power into them when the sun is not shining. I just converted my entire system from cheap to Victron, and what a dream!

I just saw the vid and had similar observations.. Thing is, observed the volts on array #1 at about 41V and array #2 at 19V. . Same question about the back feed by the arrray #1 into arry #2 at its lower voltage maybe causing something to short out. Can anyone clarify ?

In this video you place the positive cable on the terminal first and then placed the fuse on top of it. So does it make any difference or is it just a personal preference?

[@VladimirDidenko]

Thanks for an amazing tutorial!I have a question on wire size. Currently I have outback 60 am charge controller and 1 x 4 PV panels array. I ordered 2 victron 250/60 to add 8 PV panels (Voc 46.8v & Isc 10a), planning to connect 2 arrays x 4 panels in series each. Should I use 6awg cables when connecting all charge controllers to victron lynx power in? Not sure if it matters, currently I have 24v lead acid battery bank but will switch to a new 48v one when I receive my new lithium batteries in 2 month (will also add another 8 PV panels and will use 1 victron for each 8 panel array). Thanks in advance!

Great video I am bumping the voltage max and looking to add another controller and split my array in stead of replacing current controller

[@damionrussell8093]

Hi Nate, Mate, your tutorials are awesome. Nate you mention in this tutorial the need for multiple charge controls if your array exceeds a single controller. What if i have a 100/30 and increase my battery size so the i now need more than 30. Let’s say i need 60amp. Can i introduce a second 100/30 (in parallel or series) to get the required 60amp or will i need to upgrade to a 150/75? Would really appreciate your insight. I image two 30amp controllers one would cancel out the other as one would see 30amp in or will VRM allow me to override or set both units to 30amp each?

Hi Nate. Is this the best way if you have a solar blanket connected to the system when main panels are parked in the shade? Do the controllers need to be the same size if the solar blanket is smaller? Thanks you

[@StansE250]

Pretty easy to understand, thanks, of course to your presentation method. Ran it to a little hiccup in using the tool to size the CC. One panel recommendation using EZ is 100/30, using detailed it’s 100/50. Fine, purchased the latter. The problem arises in that I’ve purchased TWO of the same panels, instead of the One (intended). Using the Sizing Tool, it recommends 150/60 (EZ) or 150/85 (detailed). HUGE Price difference ! If I just bought another 100/50, would that serve my purposes just as well, though I suppose each panel would come in through roof independently. But, it would be A Lot cheaper to buy a second 100/50. Though, I wouldn’t benefit from the Smart Shunt, because I got an Alii. 😫

[@tomwilliam5118]

Great video. I noticed you put the positive wire on on first and then the fuse. Can you put the wire on first and then the fuse. Where connect to the victron distribution

Another great video, fantastic explanation as always, I've a question about 48v battery banks. I'm setting up a 48v off grid system, using all Victron products, you've explained everything perfectly so far, very useful. but, I'm a bit stumped about balancing the batteries, at this stage I'm planning on using on using Victron Super Cell Lead batteries, I'm not not convinced about lithium yet, anyway, I'd love a video showing how to connect the Victron battery balancers, it's clear how to set it up for 12v, 48v banks need 3 balancers, given the cost of all this equipment, I'd like to get it right the first time. PLEASE PLEASE PLEASE do a video 🙂

[@marinamidori2113]

Hi Nate, thank you thank you thank you for sharing your in-depth knowledge of electrical systems. I have a question for you: What type of electrical system would I need to power an Air Fryer? My cursory search on the Internet says an air fryer draws too much power. Is this possible? What would I need?

[@EXPLORISTlife]

You should do a power audit to figure that out. Here is a tutorial for that: kzbin.info/www/bejne/l2WTZ3yunrpgjsk ...also... anything is possible with the proper application of effort and funds. lol The power audit will confirm... but I suspect you will be looking at something like this: www.explorist.life/3000w-inverter-400-600ah-400-to-1200w-solar-camper-solar-kit

Very good information nice video one question how can I know the voltage input of a charge control

[@OGKushSlowMo]

I have a setup thats similar to this and I've been studying your diagrams. I'm addition to 2 charge controllers, I'll also be using a DC DC charger. Should I go with just a traditional bus bar setup in that case since I'll need to use 5 fuses?

[@Mikeonabus]

This brings up my next question, how do you feel about the lower-end charge controllers? Like the ones that come with the Harbor Freight solar panels or the low end renogy solar charge controller. It seems like these really elaborate mppt controllers are the norm, is it possible to wire a sufficient solar system with a regular charge controller?

[@paulharry2254]

Thanks for a very informative video and one that I hope will prove very useful. A question if I may. My campervan is very small and I can only fit 1 x 100w solar panel on the roof. As such I was thinking of using a bluetti 200w solar blanket as the second panel when needed. Are there any obvious downsides to this using your setup - especially as the solar blanket will not be connected at all times? Many thanks.

[@donaldsmith3025]

Nate, I understand the need to use a 2 pole breaker between the panel and the charge controller. However don't understand why the 63 AMP instead of sizing the breaker to protect the wiring. Then go add a separate fuse link which seems to duplicate but potentially add resistance to the system, Thanks, Don

[@en8581]

Great video-Thanks! Some installs on a boat have 4-6 MPPTs. Is there a way to wire the MPPTs where they don’t each take up a space on the distribution? For example, running all the positives from the 6 MPPTs to a busbar then a single wire from the busbar to the distributor?

[@bramcoteelectrical1088]

No. Best way to fuse each bud. Yes easier to just wire to one point but less safe to do so if you have a short on the output from the mppt etc. Fuse and wire each x Controller back to the busbar

I originally posted this on your video about crimping wire lugs but since this is close I thought I would post it here too. I have a question about the terminal lugs. I have a Lynx Distributor but the Selterm Cable Lugs for 4/0 AWG, stud size 5/16" are interfering with or by the plastic insulators that separate positive from negative wire connections. This interference is on both the pos stud and neg stud. I checked the spec on the part at Amazon and it is the correct width. I could force it down by tightening it, but that just seems wrong and could break the plastic. Should I shim it with washers under the lug to get the clearance? (wish i could post a picture)

[@teddy8080]

Hello Nate, thank you for sharing the knowledge in such an educational rich approach. Keep them vids coming... I have a question for you: Following the example above, lets say i have a 200Ah battery bank (a lead acid) and an DC/AC inverter where i want to always limit the battery bank charge current to a 0.1c equivalent to 20A and i still want to have available the remaining current that the charge controllers can provide to supply my AC appliances through the inverter? So how to limit the charge battery current without limiting the output current of the controller? Thanks man

[@earlhunt2815]

I went with series for following: 1. Biggest reason is Victron MPPT's don't initiate battery charge until output 5vdc greater than battery vdc; series charges batteries earlier than parallel configuration. 2. Can mix solar panel voltage outputs. 3. Uses small Guage wire

[@vectors1gma]

Hi, Thank you for your great videos, Is there a reason to use a fuse instead of a breaker ?

Yes. The fuse fits in the Lynx Distributor. A breaker will not fit in the Lynx Distributor.

[@earlhunt2815]

Nate, seeking your thoughts wiring Victron's Lynx distribtor to Victron's 2 MPPTs, DC2DC CONVERTER, 12V 3000WATT MULTI PLUS, and the DC distribution line. Since I need 5 lugs and the Lynx only has 4, my thought is to wire the DC distribution line independently. Your thoughts?

I recommend using an additional Lynx Distributor. They simply bolt together end-to-end for an additional 4 spaces.

Can you see any downsides to that?

[@EXPLORISTlife]

The 2 charge controller won't be able to see what voltage the other is charging at and the output voltage from one controller may mess with the 'battery voltage' reading of the other controller. The will also not be able to coordinate their absorption times.

[@shutthegate8232]

@@EXPLORISTlife Thanks for clarifying that re: variations that could come along with two charge controllers that don't communicate. Would the Victron app/comms ability between two of their charge controllers also allow two different size/rated Victron charge controllers to be used in the multi charge controller scenario? If the say there's a large array with larger rated controller & then a smaller array feeding a lower rated controller, but if both Victron have the ability to work out the optimum for the batteries, and not butt heads :) ? Cheers for that Nate.
