Please can someone tell me the minimum power/wattage of solar panels that I can connect to a 100 amp pwm solar controller? I fear I have bought one that is too much for my needs.

I want to power 3 devices 24/7 with my setup. I have the charge controller plus

1. Raspberry pi 5 pc drawing 5v 4a

2. Raspberry pi zero 2 drawing 5v 2a

3. Ethernet switch drawing 5v 1a

I am not connecting anything else to the controller as load apart from the above 3 units. I have one 12v 90AH lead acid battery and one 3.2v 72AH CALB LifePo4 battery. I think I can't use the LifePo4 because I made the mistake of getting the pwm charge controller right? I just want to use one out of the two batteries for my setup for now and leave room to upgrade later but my next purchase will be a solar panel to power the setup although I need help to know the right size/power of panel(s) to buy that will power all three of my machines during the day comfortably and also recharge the battery for use during the night when the sun goes down.

My plan is to connect the panel to the 100 amp controller, connect one of the batteries to the controller to recharge and use a step down/up buck converter to give me an output of 5v 10a max. Is tbis possible?

Hi, I'm new here and need guidance.

I have 3 computers which I need to keep running 24/7 because I'm using them as a server cluster. I have purchased a 100amp pwm solar charge controller and I have two batteries which I can use for this project. Details of my load and batteries are below.

1. Raspberry pi 5 drawing 5 volts 4 amps

2. Raspberry pi zero 2w drawing 5 volts 2 amps

3. Mini ethernet switch drawing 5 volts 1 amp

4. One single 12 volts 90 ah lead acid battery

5. One single 3.2 volts 72 ah CalB LifePo4 battery.

Those are the items i have on hand right now along with the 100 amp pwm charge controller. Please I need to know the right size of solar panels that I can purchase and wire up which would be able to provide enough power to directly supply current to the three devices I have as loads above during the daytime and then be able to recharge any one of/both of the batteries I have to be able to power the loads during the night when the sun goes down.

I am a complete novice in electrical matters but I am willing to learn. I do not have any cash right now to purchase an additional battery so I need to make do with the setup I have on hand right now and plan for an upgrade soon. I just have to purchase the right solar panel size and type to give me the juice I need to at least power my devices during the day and then I can depend on whatever my battery backup can give me at night for the time being.

I am in Africa, we have good sunshine most of the day. All my devices arr rated at 5 volts max. I fear I bought an oversized pwm charge controller for my setup (100 amps) hence my worry that I might have to splurge on solar panels to feed such a hungry controller.

My humble questions are thus, can I use a lower rated solar panel with the 100 amp controller? Is there a minimum wattage of panels that can be used on the 100 amp controller? Will it hurt the system if I under-feed the controller power from the panels? I don't think I have the cash to buy anything more than a 150 watt panel at the moment but I desperately need this system up and running one way or the other.

Thanks all. I appreciate your advice.

Poland usually do not generally request that student do medicals. However if your school request that you do medical test then any Private or Public Hospital is fine. Except they (school) specifically instruct you to do it in a specific hospital.

Thank you so much

Some riders are just so funny
See what someone dropped about me on indrive and this makes me loose a trip I was supposed to take all because the person saw this comment....

Eiiyah at least you wear cloth for this one, imagine what could have happened if it was on your bolt profile that they saw this kind of review












Donbrowser where are you? One full month nobody see your brake light on the forum . . . Why? I hope you are still with us in spirit sha, because many people that followed you to 'RoNu' from here are still with us in body

neccki please where can ome fo to do medicalsnfor study visa to Poland?

I went to Qlife but they don't do for Poland also IOM stated on their website that I need to have a certain information from the embassy before I can apply for medicals with them.

Is there any other organisation that does medicals specifically for Poland? Thanks

Lightmykpoli please where can one do medicals in nigeria to migrate to Poland for studies.

I went to Qlife and they don't do for Poland. IOM says I need a reference from the embassy before I can do medicals on their website. Is there any specific medical organisation that offers medicals for migration to Poland apart from these two?

Greetings Bosses in the house. I recently gave my mechanic money to buy new gear hoses for my matrix after i found out its leaking. Fee days laterone of the hose burst on my way back from a trip and all the gear oil were lost . Had to park the car and look for a mechanic it was then I noticed that one of the hose isn't meant for gear oil.
New hose was bought as well as new gear oil and the gear got back on actio. I drove down and confronted my mech. He apologized it wasn't intentional, then i told me to pary nothing happens to my gear.

Few days later the gear would take few minutes to engage in the morning and drives fine the rest of the day till d nxt morning, sometimes i will have to shift to D2 b4 it will engage.
Called my ,,m ech again to complain and he suggested we wash the bottom plate that its dirty.
We did that yesterday and it took the car much longer time to engage this morning. But it drive normal since today.

Please I need your candid advice/ suggestions.

Neither any part of the engine nor gear has been worked on since I bought the car 2019, expect the plugs

Your gearbox was driven for some miles while under severe starvation of lubrication

I'm sorry, it will only get worse. Just fill up and never touch it again and watch its deterioration. It would get to a stage and then stabilise but I doubt it will ever function as it did before the unfortunate 'hose bursting' incident

You'd have to manage it as it is so far as it still functions for your use.

@Conner44

Bossman, I no dey talk about you oooh.
I no even dey accuse anyone at all at all.
I just drop am there to let anyone who ACTUALLY thinks (or might think) the thread is useless to see.
I dey see some of your comments and they very educating wellah.
Be like you dey drive self, abi?

Much respect, boss.

I drive oh, only I don't utilise any app to do so. Just keep doing YOU and allow them to keep doing THEMSELVES and the world will keep revolving as it should

Enough respek 🙏

Omoapena:
Do you know that I'm actually suspecting catalyst for my engine oil burn, I guess that might be the culprit coz when we opened the top cylinder, the camshaft is still very clean and there was nothing like smudges inside.

I will fix another catalyst to see the effect

No no no, you didn't understand my post.

Bad catalysts or O2 sensors are both symptoms of oil burn and not its cause

Blackbishop already hinted at your valve seals (minor repair) as being the culprit. The other culprits could be bad cylinder walls (major repair) or pcv valve (easy replacement)

Glithronix:
And someone, or some set of people, would come here and be blowing trumpet say this threat is crap and dead.
Oya you self talk, shey the thread is useless?
People dropping their experiences, advices and encouragement since, shey you self no learn?
You still bitter about this thread?
Shior.

Much respect, bosses.

Are you indirectly speaking to/or about me?

See, learn to discern sarcasm and intent in vocabulary. It will help you.

If you check properly without any bias whatsoever you'd realise that i am one of the people who advocate for the livelihood of this thread against all odds , most people say nothing or hide behind innuendos to make their own opinions known (you yourself do this) and it's okay 👍🏾

Anytime you see me here coming to post about 'this thread being dead' was only done to Ginjah people like you and others to keep posting if for no other reason at least just to prove me wrong . . . And for the most part it worked

I have said it not once or twice here before that I respect you for always putting in the work right from when you joined us here till today and my view has never changed. Just calm down, relax and know who the real enemies of this thread are and you will get clarity on many levels.

Other members have gained theirs even after attacking me here, its okay. I always knew they would come around. Time is the only factor but the truth always reveals itself.

Much respect 🙏

Blackbishop:
No bro....

Good take. A vehicle shorting oil is not the end of its life or usefulness. Just do your cost valuation against management or repairs and take action.

Like me today, I have oil shortage but due to bad leaks, my engine will need to be dropped for the repair which I don't have the time to do now or intend to do anytime soon (so as not to allow a mech add an issue to my issues) so I just keep topping up as necessary.

I even travel very well with it, here to the east and back frequently. I just stop at Ore and top up a litre and it will be low again at my destination. That's how I mitigate its adverse effects during long distance trips. On a daily I top up a litre in like 700kms in my usual city drive.

The fact is if its due to an oil burning issue, then the catalysts or O2 sensors can get bad quickly if it's not tackled on time. This is where I am lucky

Give them money for paracetamol and instead they will go and buy KoKain since papa no dey again to sustain wealth money no come dey flow like water again soo-teey

Otilo! All of them kpai Sara

So, scammers these days have a new trick. I almost fell for it and almost lost 50,000 naira. Here's how they operate:

they post items on Facebook or other platforms with a "pay on delivery" option. When you inquire about the item, they'll ask for your number, delivery address and ask if you are available to receive it. Then, a dispatch rider will call you to deliver the item. The scammer will stay in touch to make sure the rider reaches you. When the rider arrives, they'll ask you to pay them directly instead of the dispatch rider & If you make the mistake of paying the person that posted the advert on Facebook or anyother platform, you've been scammed successfully...


Pls becareful out there

I don't understand this part of their scam. Shebi if I pay the guy that posted the advert online, the dispatch rider in my front on his bike is supposed to give me the item for sale which I wanted to buy WHICH HE SHOULD HAVE INSIDE HIS BIKE BOX abi? Will he zoom off? Or is he unaware of the scam?

TheModerator:
Why don't you stand up to the challenge and prove me wrong? Proove that it's a lie. Enough of the talking. If you think you have a business on this thread, embrace the challenge, show proof why you must have a voice on this thread or forever remain silent. Enough of the thrash talking. Come out and drive on Sunday, I'll offer you a car if you have none or forever be quiet here.

Have you yourself shown anybody proof of all the baseless accusations you have been making against members of this same thread? Off the top of my head I can mention at least 10 accusations against others here which you have made and up till this very moment you still have not shown any proof or even withdrawn such accusations

I mean, you're holding up a mirror 🪞 drop it first and start requesting proofs of whatever you wish to make yourself feel good

TheModerator:
Let's do this on Sunday? 12 hours straight if you can? But na leggedes Benz you dey use. You can't drive without a car.

You failed to mention the hazard university mechanic the smelling black one aka blackbishop who has no apprenticeship or mentorship certificate. The only thing he knows how to do is cut and join English...lol... That guy almost knock my engine.

BATified2023:
ok

Which region are they?

Lagos state indigenous people said they don't want to be in the south west. They want to be in the WEST-WEST and that is the regionalism they are pushing for.

So as there is a south south, there will now be a west west simple.

So better remove your eye from lagos on time and face your illaro

Keep overfilling your fuel tanks at petrol stations feeling like bosses una go learn

Lekan239:
its been a while boss. Its been over 1 year and six month using the civic and I'm enjoying the car, its fun too drive, very fast acceleration, it's actually a beast on the road... my major problem is getting the actual part for the car, as the part used in this civic spec is not readily available in Nigeria, the parts are totally different from the regular civic of the same year..

The engin and gear is in good condition as I often paid attention too the dashboard light and repair accordingly..

It's using electric power steering. I'm using mobil oil 5w-30 the Ash cover about 50k now and change every 4month or 4000km... the car is still in perfect condition

Awesome news. That civic will serve you for years to come with the words I just read above from you 👌

What spec is your civic? Not American?

Modified

Ahhh 😆 no mind me. How can I ever forget you. You're the one with the civic that is a UNICORN

Guy, no sell that car. And even if time to sell reach abeg buzz me

Why you always choose to cry more than the bereaved is what beats my imagination

You always rushing to type what you have no clue of which to me is a huge display of intellectual hooliganism

The person I had issues with is long gone but you choose to carry it on your head or you think say I dey your league of clapback or banger tweets?

Did I drop my account details for any give away from don?

The thread is de*d the thread is de*d, how many pages have passed now?

Your shadow should even be ashamed of posting anything here


You better be guided

Useless nicompoop

Yen yen yen all talk no evidence

The person you had issues with is long gone abi? yet, you still followed the same person you had issues with to his telegram group because of what? Meanwhile if they ask you what your initial issue was with that person you won't have anything to say or point out

All this your shalaye still won't change the fact that you're a shameless beggar, with a stint of jealousy and envy

There's a reason why these three words are mentioned everywhere you read about engine wear and tear . . .

STARTUP

COLD ENGINE

THICK OIL

no be me talk, na the manufacturers and testers themselves talk am.

If you're driving a vehicle with an aluminium engine without thermostat and using 20w50 oil I am sorry for you. Vehicles with full metal iron engines don't have this same issue 😕
