A Tour Of My 24v Solar Set Up For My Off Grid Home

[paulgrassi]

I'm also working on a 24-volt system with 10 batteries putting them together in series as you did only I was told on the opposite side where you putting the positive and negative together for the two batteries the batteries that are posted that are in the center left to run to a buzz bar each one being five separate post going to the bus barn before you run them out will the batteries are not going to charge and discharge equally if you check that and find out that I was told differently one of us is setting them up differently and the batteries are not going to charge and discharge correctly let me know thank you

Good vid, nice job. I take it you have resolved the shunt placement issue by now and have discovered the true value and accuracy of ur Victron smart shunt. Cheers

Hi Ben

I just found your channel as a YouTube suggested video and I think you did a great job explaining all the components.

There are however a few problems with your termination points for the shunt, batteries and your grounding that will create some problems with accuracy with your BMV712 and possible shock hazards due to your grounding.

They are all easily rectified issues and won't cost you anything to rectify. However as I said you do have the potential for hazardous voltages on your system that need sorting.

I am an ex Navy electrical engineer with 30+ years of experience with high and low current DC and AC systems. I love seeing someone of your age who I can see has a love of electronics and a bright future ahead of you. You are a smart guy I think as you demonstrated a great base knowledge of your equipment.

I am not knocking your instalation, in fact I think you have done a great job. Your system just needs a few tweaks to make it a little safer and increase performance.

If you want I will be happy to talk to you on WhatsApp or any other voip system to give you a hand. I have plenty of free time as I am bedbound after spinal surgeries that have gone wrong after an injury so I have plenty of spare time on my hands.

Let me know if you want to talk direct as I am happy to help you out.

All the best.

Great overview, thank you. For people that really want easy, consider using an all in one 48v charger controller inverter and higher capacity 48v LPO4 batteries... the 48v will allow for higher input PV voltages with smaller gauge wires and use of high capacity 48v lithium iron phosphate batteries will allow for fewer batteries and simpler wiring... also will have better operational temperature range and remove the need for heating and insulation in most cases

[peterhartmann]

the shunt needs to be installed prior to the negative terminal block. this way the system will see the charging current along with the draw current then you will see the true battery state of charge....

I was wondering where you went. Thanks for the info.

I live in Renton, Washington. Nice set up. I have pretty much the same thing, 24 V 3000/70. I have four charge controllers and they’re all Victron. I have eight Battle Born Batteries 9600 Wh. Use a Victron shunt. I have 24 solar panels for 7.7 kW.
I replaced all my appliances with 120V. Got rid of my 240V oven, but kept the dryer and flip over to the grid when I need to dry clothes.
I need to upgrade to 48 V for better efficiency and more power. I’ll probably get a 5000 instead of my 3000. Trying to learn about split phase.

Nice job on your system. I’m surprised that you get enough sun to charge your batteries in Washington, Do live in eastern side of Washington? Did you run the wires from the breaker box in the shed to the house underground?

You mention " 120 amp inverter " 5000 watts at 120 volts is 41.6 amps. The 24 I 5000 I 120 on the front of the inverter designates 24 volts, 5000 watts, 120 amp battery charger . One other thing I noticed is your wire / Breaker size. Your wire needs to be sized more than enough to carry the load and the breaker sized to protect the wire. If you have too large a breaker on a wire to protect it the wire becomes the fuse and will melt / cause fire. Nice equipment, I am a big fan of Victron gear .

[FOLLOWINGWALKERSWORLD]

Great explanation of a simple system. 👍😎✌️

[schleifermax]

Very nice system👍. You could invest a little more love in make it beautifull.

[mosbysmen]

great system, i would cover the buss bars with plexiglass

[noahriding]

When people have their whole house like covered in solar panels... how do they chain them together safely, when you have more panels than just 1 charge controller can handle? Is there a specific way they work this out?

[harlanmclain]

You got to much in ur battery's $20.000 for what u have is crazy man but good luck & God bless

[bryanroye]

Can you give me the link to where you got the surge protector?

[cleversolarpower]

Nice video. However, you could have used a 48V system and save money on wiring and charge controllers. And it will be more efficient.

[vargasmongo]

mucho importante yes well said brother 4:40 😊

[michaeledge]

Does it help to tin the wires with solder before installing in the clamps?

[rontech]

I don't see where your panels are all grounded together where is the solid copper going to your panels and grounded at?🤔😱

Aziz Ahmed Ansari (AAA) I am sure you have got a lot of comments for the simplicity and easy explanation, This has instigated me to contact you. I am thinking of putting a 5Kw 24v Solar generator in my basement. I live in Minnesota and thus thinking of a more efficient system, thinking of a battery bank of two 24v 250Ahr batteries, a 24 Volt Pure Sine Inverter Charger, 6000 Watt Low Frequency Inverter 110/220Vac Split Phase, 18000 Watt Surge, Battery Priority Selector, Terminal Block, GFCI. I have no clue what-so-ever about the size of the charge controller(s), solar panels/capacity and how many, fuses and other components. Can I request you to help me, let me re-phrase it, how would you do if you had to build a 5Kw, 24V system for yourself. Thanking you in anticipation.
