In this video, I'm going to walk you through a complete 5kW off-grid solar system, covering everything from selecting the right components to understanding the overall costs. We'll break it down into three simple steps and give you all the details you need, including a 5kW solar diagram.
We'll start by choosing the solar panels and charge controller, then move on to sizing the battery, and finally, we'll choose the inverter and generator. I'll also provide a detailed wiring diagram with wire sizes and fuses, explain what this system can run, and break down the total cost.
Topics Covered:
1. Choosing Solar Panels and Charge Controller: Learn how to select the right solar panels and a 100A charge controller for a 5kW off-grid solar system.
2. Sizing the Battery: Find out how to size your battery to store enough energy for your needs. We’ll use three 48V 100Ah server rack batteries.
3. Choosing an Inverter and Generator: Discover why the Victron Multiplus 48V 5000VA inverter and Honda 3000W generator are great choices for this setup.
4. Wiring Diagram with Wire Sizes and Fuses: Get a detailed 5kW solar diagram showing the wiring and fuses needed for safe and efficient operation.
5. What Can It Run?: See a practical example of the daily energy consumption this system can handle, perfect for tiny houses or cabins.
6. Cost of the System: Understand the total cost of a 5kW solar system with battery, including all components and installation materials.
The total cost for this 5kW solar system with battery is approximately $12,000.

Very Nice Explanation Thank You for sending The Free Diagrams 💐🎁

You rock!

excellent

[@linossinkala7840]

Thankyou sir

[@brymstoner]

nice, but people don't typically unplug their fridges or freezers overnight. from my own experiments, i can run my whole home entirely off my 820W of solar and 7.5kWh of lfp batteries in the height of summer with decent sun (uk, so sometimes it's a gamble!). the rest of the time i plug the fridge freezer, and sometimes the microwave, into the grid. it's not worth grid-disconnecting in the uk - but when there is a powercut, you're usually back on within 8 hours. anything longer, and i'll take the hit as best i can with my solar system.

[@RadanarAung]

Thank you I am trying to be a off-grid soalr designer.

[@herbertvonsauerkrautunterh2513]

I will be using 440w panels with the same charge controller. I already have 20kw of rack batteries which aren't enough.. I don't run much at the moment. I will be buying more batteries to get to 40-50kw. My inverter of a growatt LF 12kw. It will be set up and fused for 300a max.

[@cleversolarpower]

300A fuse size seems ok. The charge controller is great. You can build your own battery as well. Check my video DIY vs BUY lifepo4.

[@johntheaccountant5594]

At 1:10 where did you get the "charging voltage" of 57.6 Volts from?

[@cleversolarpower]

It's the charging voltage of a 48V lithium lifepo4 battery.

[@captronsilveira7087]

Nice explaination. However I did not understand how the charging voltage is derived.

[@cleversolarpower]

It's the standard charging voltage for a 48V lifepo4 battery. For a 12V battery, it's 14.4-14.6V.

[@stevenski_brewster]

Does Victron offer an all in one control center / inverter / charger for this 48v application? Rather than having 2 components. Thanks

[@cleversolarpower]

Checkout Victron easysolar.

[@robertpaulis439]

Nick...please help me understand how you connected the 2 sets of panels to the charge controller??? Your diagram appears to have 1 set going into the "load" outlet which I question. Thanks

[@cleversolarpower]

One set consists of 6 panels in series. It would have been too big to have it one the screen. The charge controller has two MPPT inputs.

[@robertpaulis439]

@@cleversolarpower how does one connect 2 sets of panels if the controller has just 1 panel hookup?

[@ihabahmed1132]

how did we get the charging voltage 57.6 V ? are you assuming using a 48 v battery ?

[@cleversolarpower]

Yes, we are using a 48V battery.

[@konkaragounakis5924]

Excellent presentation, now let me get this right, you can't connect 12 panels in series because of voltage excess, but can you split the voltage 6 panels = 276v in the same charger controller Is this correct? Again great show I enjoy it, thanks Nick 🇦🇺

[@cleversolarpower]

Yes. The charge controller has two mppt inputs, so yes that's why we can separate them.

[@konkaragounakis5924]

@@cleversolarpower thanks for explaining this, excellent explanation.

[@OffGridLivingEspana]

are the 20amp circuit breaker also for surge protection/lightning?

[@cleversolarpower]

No, just for isolating the solar panels. I might do a video about surge and lightning protection later.

[@OffGridLivingEspana]

@@cleversolarpower ok thanks will look forward to that one -

[@graphguy]

Yesterday I saw a video that shocked me. on traditional panels --- ANY shade shatters the pv output. The video demonstrated that even a 5% coverage of shade dropped the output from 93w down to 17w. What do you say?

[@cleversolarpower]

It's true. If you look closely at a solar panel there are cells in series. If one cell receives less irradiance, the current will drop. And the panel will take on the cell with the lowest current.

[@godswillasagba3949]

Please what battery backup, inverter, fuse, wire quality and size is recommended for an 8kva pv array? Can you draw a schematic or do a video on it? A customer ask me if i can handle such solar project. For this is the exact off-grid solar his friend is using in powering 4 ice block producing machings and he needs this too to power his own. I'm from Nigeria.

[@cleversolarpower]

You can take a look at my designing service on my website.

[@jameswebb80]

Is it possible to run a 24 V 16s BMS system on 16 3.2 V cells configured in an 8S2P configuration or do you need to separate BMS units?

[@cleversolarpower]

I don't think that is possible. You need a 24V 8S BMS and wire your cells in 8S2P. So wire 8 sets of 2 cells in parallel, en then series connect them. One balancing lead for every two cells.

[@jameswebb80]

@@cleversolarpower thats what i thought but wasnt sure

[@godswillasagba3949]

Can a UPS SYSTEM substitute or do the work of an INVERTER if i remove its internal 12volt battery and run a wire out for connection to external bigger capacity 12volt battery...? Can it power a house? And what are the similarities and differences between the UPS SYSTEM and INVERTER.

[@cleversolarpower]

To my knowledge an up is a battery charger, inverter and battery in one. You can switch out the battery for a larger one, but it has to be the same chemistry and voltage. It depends on the power output of the ups. Most likely very small. This 5kw system is basically a big ups.

[@alainalbert6663]

So with this setup the charging amperage is reduced to 36 amps..does it mean that with a 24v system the charging amperage be raised to near double to fully use the generator and the inverter capability? Will it charge the bank twice as fast? I'm asking cause i just bought 7 6v batteries that are 9 years old but can't find an other one with the same age to go 48v..so 24v system is on my mind now. I'm new at this. And what make the Honda 3000w more economical than others..i got a yamaha non inverter? Thanks 😅

[@cleversolarpower]

Increasing the voltage will reduce the current. Power= voltage X current. So if you increase the voltage, you have to halve the current to get the same power.

[@alainalbert6663]

So it will be charging at the same rate..?

[@etiennealexantoine4299]

Hi

[@wenzydemar4406]

so in this calculation the battery banc will have a dod of 100%??

[@cleversolarpower]

Yes, it's lifepo4.

[@davet9633]

Victron 5000 is not UL listed; thus, not a good choice in CO (if you want insurance to cover any issues).

[@cleversolarpower]

Victron 48V MultiPlus-II UL1741 3kVA 120V is UL listed. You can place two in parallel to get 6kW of output. I linked it in the description.

[@nomsTube]

Why would you run a fridge for only 8 hours? Usually fridge and freezers are always on.

[@cleversolarpower]

No they are not. They usually have a duty cycle of 30%, which means they are on for 8 hours a day. Check my video about: how much power does a fridge consume? And you will see what I mean with the graphs 😉

Too expensive for me, hi quality components are expensive, i think a 24 system with 2v led acid batteries and a easy solar 2 gx everything here is over priced.
