[@brandonlacour1277]

what are you gonna do with all your old components and batteries?

[@fisherus]

I want to give you a little advice on safety on your solar system for two reasons. One is, you aren't aware of them and the second is those folks watching how you do certain things are probably going to be making the same mistakes. Never connect your positive wires last on DC current but, connect the "Negative" wires after placing a 1 ohm resister between your hot negative ( battery or power side) and the negative you will be attaching it to. Make sure you touch both leads on the resister to both negative wires or terminals and then immediately connect the two. This will keep from blowing up electronic components inside of your charger and inverter. I'm sure you heard the pop sound when you connected the positive side of your battery bank. Additionally, use shrink tube on all wire terminal connections. The cable terminals on your batteries look terrible and will corrode without using it. You have way too much bare copper on your terminals exposed. Finally, you should have a PV disconnect switch on the outside of your solar shed to turn off your system in case of fire.

[@gastongonzalez221]

Great advice. It looks like there should be another fuse between the solar charge controller and main positive based on the amps the panels are pushing, right?

[@kuhrd]

Using a precharge resistor is a very good idea and with most inverters and charge controllers is a requirement. As far as whether you connect positive or negative last or first does not matter since everything around the batteries is wood and non-conductive at the 24v he is dealing with here. The only time it is a good idea to connect the negative last when making a connection or disconnecting it first when breaking a connection is if the chassis of whatever you are working on is grounded to the negative cable so that if you are using a wrench it won't matter if you short it to the chassis. If the chassis is positively grounded which is still common in old tractors and some vehicles in countries outside of North America then the positive would be the best connection to make or break the circuit. Regarding the cable terminals, these crimps will be just fine, and since these batteries are in a shed protected from the elements they won't really corrode since they are lithium rather than lead-acid. At the most, he could apply a bit of dielectric grease as a barrier but it is never a good idea to heat shrink battery cables unless you are using it as a barrier to prevent short and then you should use clear heat shrink so you can see the connection since most heat shrink will hold in moisture making corrosion more likely. Having a PV disconnect is also a very good idea at both the array and in the shed.

[@aqpham84]

Are you saying he should connect both negative leads to the resistor to complete the circuit then bypass the resistor by connecting the negative leads together? Just asking to learn.

[@kuhrd]

@@aqpham84 Yes the resistor bridges the connection first and allows the capacitors in the charge controllers and inverter to charge up and equalize to the battery bank voltage more slowly which also dramatically reduces or in most cases eliminates the spark when you make the final connection. You can also buy DC isolation switches that have the precharge resistor built-in which is the preferred method since an isolation switch is a code requirement in the USA IIRC even if off-grid and just makes common sense in any semi-permanent install.

[@offgridbydesign3826]

Great upgrades. A couple of safety suggestions. 1. Add a disconnect switch at your panels. 2. Add a disconnect switch at your batteries (this will also prevent sparking in the future if you have to disconnect or you can use a resistor to drain the capacitor in the batteries before connecting) 3. Add a lighting suppressor to system. 4. Add a grounding rod at panels 5. add a grou d to your generator. Great progress, keep it going.

With all the money you’ve put into this, is it EMF protected?

[@routerfixer]

Why don't you have any isolators in the cables? I have solar on my narrow boat in the UK and we have isolators on the positives from both solar arrays to the controllers. DC breakers between the solar controllers and the batteries, and the charger for when we are on shore power. Plus a main fuse and isolator on the main battery cable. It makes it easier to disconnect and the isolators stop the sparks when you reconnect.

[@orange11squares]

if one battery goes bad then all you have to do is remove the connection between that battery and the one along it connected in series with it. The current wont flow on 2 series batteries (one good and one bad) and you have 6 left. Shelves on each row is a good idea.

[@theshmucky2956]

I have watched so many videos that just confused me even more... thank you for finally explaining the basics to set up a decent solar powered system!

[@Joakimny]

Just a tip, to avoid sparks, connect positive first, then the negative. When disconnecting take off the Negative first. The same goes for anything on DC power, otherwise 2 thumbs up.

[@Hefek]

The "positive first" rule applies to conecting and disconecting booster cables when jump starting the car. To avoid sparks NEAR THE BATTERY, you connect the negative clamp to car body or engine block and remember to always make and break connection at this (far from battery) point. This is to avoid ignition of hydrogen / oxygen mixture gassed out by battery when charged at high rate.

[@hwangeva1464]

Sounds good suggetion

[@noneya3504]

Again, very nice setup. Just one step I would have taken. Your short negative wires have wire exposed between the lug and the coating. Always a good practice to use heat shrink or electrical tape to wrap the gap so there is no copper wire visible. Just for safety.

[@patmccormack8135]

The Sigmaform heatshrink has meltable glue on the inside. Stops it sliding and acts to stop moisture.

[@101markharris]

What about the bare lugs ?

[@RyanJWassink]

Love it - I didn't notice anyone else mentioning strapping the batteries to the wall or putting a cover of some sort in front of the electric connections. Knowing my luck I'd walk in there with a shovel or something, spin around, short it out, and zap myself. I'd then jump 2' high and knock those batteries off the wall. Personally (not that anyone asked) I'd probably a shelf out of OSB that would go between each battery and then some threaded standoffs so that you could put a sheet of plexiglass in front of everything as a guard. Attach with thumbscrews so that it would come off quickly. As a middle school teacher I'm always thinking about what a typical 7th grader would do - and unfortunately "zap himself" is the first thing that came to mind :-) LOVE the video and the content! Just getting ready to start a solar cabin project.

[@danielsundberg1977]

It would good to know what these items would cost us and not what you got them for for promoting Battle Born.

Good observation I would add since batteries are not really intended to stack on their sides at least use some spacers at the front to compensate for the width of the battery clamp downs at the back. Will also improve airflow when they are heating due to high draw rates or for the battery warmer below in Winter!

[@thelostarchivesserialvault5353]

Just a thought...Why not spray foam insulate the shed? If you mount a small solar panel on the shed roof you can use it to power a small heater fan in the shed. With a shed that small and IF the shed is sealed and insulated then it will easily keep that shed warm in the coldest temps. Have you considered installing a wi-fi cam in the shed? Also, so you don't have to go out to the panels to disconnect power there, you should consider installing a disconnect inside the shed. Would make your life easier for maintenance.

[@MrSummitville]

[@ChatGPT1111]

I love my Battleborn Batteries and recently added 4 to my existing 10 AGM deep cycles which are now serving as my backup. They do come delivered with only a 30% long term storage charge level so you should charge them before use. Also, don’t forget the cutoff switches and fuses. I have fuses at the solar cells plus a lower level DC circuit breaker to save the fuses and the hassle of changing them.

[@kimmer6]

I have 2100 AH in cell tower AGM batteries and a new set of 1600 AH in LiFeP04 batteries. Each has different charging requirements and both banks are isolated. I don't know how you switch your banks but my major improvement was to add a Blue Sea marine rotary selector switch that is sealed and spark less. The switch is rated 500 Amps continuous and you can select Bank 1 or Bank 2 or run them combined or switch the batteries off. The switch was $70 on eBay. You can tell the thing was built for serious Amps as the connection studs on the back are 1/2''-13. The smaller switches have 3/8 inch studs. I leave it on Bank 2, the AGM's, and its float charger. The lithium cells get a charge about once a month from their own charger when I run the Onan diesel gen set for 20 minutes. That $70 switch was dirt cheap in the scheme of things. It switches banks or disconnects in half a second. It might fit your situation. A hydraulic terminal crimper gets a lot of use here, too.

[@kencissel5663]

Two things surprised me about your installation. One that you would just stack the batteries rather than make individual shelves for them, and second that you didn't install any kind of disconnect switch on the positive side of the battery harness. The large spark when you connected it showed very clearly the need for one. Other than that, a good install.

Yup, I was just going to post the same thing. Also he can't use just any breakers/switches between the panels and he charge controllers because of the high DC voltages involved. On the big array he needs components rated for 100 VDC and he needs components rated for 75 VDC on the smaller array based on how it appears to be wired (series parallel). I also think the wires from the charge controllers to the shunt and batteries are undersized. That 70 output Victron controller needs #4 wire and the 50 amp controller needs #6.

[@tonysmith26]

Yep. This ⬆️⬆️⬆️

[@TerryCassar]

Love the set up. Just be aware that lithium batteries operate completely different then AGM, Lead Acid etc. first rule of thumb is to fully charge the batteries individually. The reason is that they might be at different voltages. Lithium batteries don’t automatically balance themselves as do lead Acid batteries. Now if your batteries are not balanced within 0.2-0.3 of a volt of each other, the situation can snowball thus resulting in a severe in balance. If this happens whilst your using your inverter at full noise you can destroy one of your BMS units in one or more of your batteries. I’m not familiar with those batteries, wether they have some hidden BMS that balances all your batteries. I’m speaking for a general setup. Cheers

[@V.Z.69]

How does a lead batter balance it's charging in series and parallel, and lithium not? It would seem that circuitry (a programmed motherboard) with switches would be necessary if that's the case. But again, how would a lead batter stop charging and pass the voltage down the line to a more-depleted battery? Interesting subject, something I'm not familiar with. But we need some insight to make this a worthy footnote. Cheers.

[@rmr4173]

Good Point! that was precisely one of my observations. By experience definitely is very important to fully charge all Lithium batteries first no matter the model. If it is not done, in some untypical cases they start to register a false load readings and shorten their useful life. Unfortunately Lithium pricing will keep increasing.

You can avoid the spark by precharging the inverter's capacitors. Connect the battery via a high power resistor (e.g. 25 Ohms/25 W) first; this limits the inrush current. After a few seconds the caps are charged up and you can remove the resistor and attach the battery cable permanently. This also doesnt stress the caps as much.

[@gsantee]

Seconded.

[@tonyleverett1483]

3-way rotary switch for isolation - off/precharge (via 50Ohm, 50W resistor)/direct (bypassing resistor).

[@ElJasperino]

Question Stephan, if you don’t use the resistor, can it damage the equipment?

[@tonyleverett1483]

@@ElJasperino you ask about the use of a resistor - if you think of when a light bulb 'blows', it's always when you switch it on. This is due to the inrush current being much greater that the current when in use (the filament is cold, and so has very low resistance indeed). The use of the resistor limits the 'inrush' current to a reasonable level, thus pre-charging the inverters input components (primarily the capacitors), thus REDUCING the RISK of damage from the inrush currents. Over the time I've been looking at off-grid power, I've not seen any reference to them being 'needed', but virtually every KZbin channel I've seen (eg TheDigitalMermaid) seem to be using them, and as one with 50 years playing with electrics, electronics, computing and radio, I'd probably say that there is a greater risk of damage if you were not using it.

[@zalleywaalley8227]

You may already know this, but next time you’re working on that system get rid of that fuse and put in a resettable breaker, and put one closer to your positive battery terminal preferably within 6 inches that way if you have to disconnect and reconnect your batteries, your trip the breaker so that when you’re reconnecting everything you don’t run the risk of Causing an electrical arc. Just a thought nice looking system though

[@RonCimo]

Do you have an example of the type of breaker? Maybe a link?

[@ckzckw]

This was really educational and so so helpful. You people in the USA are so lucky to be able to do this, I'm not yet on the property ladder here in good old Britain but the charge on those battle born batteries has me thinking of havin a set for downstairs and one for upstairs so I have a good charge up for our lovely rainy and mild weather. :) Im so here for when storage can be as advanced as mobile phones. I'm looking into the same for residential wind energy that would be perfect to hybridise for UK climate. Thanks again every thing was easy to understand the steps to set up.

[@offthegrid6276]

Just a little advise, always protect your battery string with a inline fuse connected at the positive battery terminal of your battery string to where it feeds your equipment, lacking that fuse at the battery terminal, you can have one heck of a explosion should there be downstream fault, ahead of your system fuse. Always protect at the source, then another downstream to protect equipment. Also the wiring for the batteries is terminated with terminals, not connectors, terminals terminate a connection to a device, connectors splice conductors to each other.

[@WindwalkerHomestead]

Nice looking setup. Battle Born. Simple, plug and play. You technically don't even have to have a lithium setting on your controller to use them. Ane...made right here!

[@bigoz1734]

Always disconnect or recconect the negative side. Don't connect an active positive wire to a system. Also you need to secure or strap those batteries back so they're secure to the wall or ledge

[@Chris-fo8wp]

I used to do a lot of big solar installs on Houseboats, we installed breakers on the panel inputs to the charge controllers, and had battery switches on the positive leads to the battery bank. Also adhesive heat shrink all connections, and cover all the positive connections. LiFePO4 is definitely the way to go, faster charge rates, better deep discharge rate. Cost wise compared to lead/acid, the break even point is around 7 years, not counting the labor involved, changing out the battery bank. The LiFePO4 should last 10+ years easily.

[@MrTimjwilson]

With the cost of a 12V 100 ah no-maintenance at around $ 90 to $120 and lasting about 3+ years so 10 years = 400 and a lithium 100 ah at around $1000 for around the same time period, economically I don't see it yet for a typical dirt farmer off grid family. Maybe I'm missing something.

[@danielbaker716]

couple minor comments: 1. use tinned lugs for custom cables to prevent oxidation, and heat shrink over the gap between lug and cable insulation. 2. you'll get much better crimps with big 36" lever crimper rather than a hammer crimper, but they do cost $200 or so which may not be worth it for one job.

[@CharGorilla]

Definitely a +1 to the Heat Shrink. Makes everything safer, and depending on your climate will go some way to preventing corrosion..

[@2Ply789]

I thought about saying the same thing along with at least 2" of Marine grade (glued) heat shrink per lug. The proper crimper is designed to produce a "Cold Weld" with a soft return to individual strands. I also used tinned Marine Grade cables but my system is in a Vanagon so vibration and corrosion was more of a concern. Also, a LOT less cable needed. The price of one foot of 2/0 today was $7.38 USD... OUCH!

The wires are in a building. They aren't at risk of damage unless you spill something nasty on them. These battery don't vent acid gases that can cause damage. Hammer crimped is fine for this application. There are always better ways to do anything but there are limits to what is reasonable.

The spark comes from the inverter's capacitors charging up. You can avoid it by "precharging" them using a resistor (e.g. 25 Ohms 25W, or 50 Ohms 15W): close the circuit between battery and wire over the resistor first, which limits the inrush current. After a few seconds remove the resistor and attach the wire permanently to the battery (withoug too much delay so the capacitors dont have time to discharge).
