I was told that my battery of 5.5kwh*2 would last only 6 hours at full load when both sun and light are not available. If that's true, which is yet to be established, it means 15kwh should last roughly 9hours which wouldn't be enough to get me off grid from 9am to 9pm

Is your business constantly busy from morning till night?

It's very unpredictable. Sometimes it's very busy and sometimes not

Guys, I need your help.

For the past two days I've come back home to my Sako Solar Inverter beeping, not charging and displaying Error 51 which is an Overcharge or Surge Error.

In fact, yesterday, I had to change the SPDs just to avoid any further complications. I noticed that once I put the SPDs off, and it running on the batteries it doesn't happen.

What exactly is happening? The weather has been poor but it can't be the weather or external forces? What should I do? Does the inverter need repairs or just some code issue? Thank you.

I'd run installation for my gamehouse within the next 2-3 weeks

Pls house I need you to tell me what's wrong with this quote given by my prospective installer. Focus less on the price and more on if the setup will be okay for the gamehouse and how to prevent issues with the setup


These are what the gamehouse would comprise


Lg LCD 32 inches TV 140w *2
Samsung 32 inches led 56 watts *3
Samsung 32 inches lcd TV 110 watts *2
Samsung 15 inches lcd TV 40 Watts *3
PS2 fat 80w 3pcs
PS3 super slim -85Watts 2 pcs
PS3 slim-85 watts 5pcs
PS4 slim 100w 2pcs
Ps5 1 pc 200w
Yokaho DC ceiling fan 40w 1pc
1 duravolt 18 inch standing fan 27w 1pc

Note: I'm yet to get ps5 but it's in the pipeline. Also only 7 out of the combination of 10 PS3, ps4 and ps5 can be operational at once due to limited number of 32 inch TVs




This is what he quoted for me for the above setup

Is there something that should be tweaked for more efficiency?

Hi

I made a quick run based on what you post. Details below:
1. You daily energy consumption is around 20KWH assuming you run all appliances for 12hours with 3days autonomy. This make total battery storage bank higher and oversized.
2. I also did a quick run saving should you use generator and daily fuel purchase of 15000 for like 6-8hrs also assuming you have s 5kva generator to run these thing. see image 2.
3. Image 3 shows the full energy audit result based on your post and benchmark assumptions.
3. From the quote, there are still questions around the cable sizing which are not clear. This is soley for safety reason.
Further more, you can view the full detail report with your exact quote below.https://www.solarspec.com.ng/p/95144d66709a44248fa572a93e62e358bcfbf3f28856331d

Recommendations: I think you should look at the cost savings over a period of time. The major problems of going solar or off-grid is the initial capital. In most cases, the system pays for itself over a short period of time compared to the lower cost enjoyed from running a generator and all other future running cost that comes with owning a generator set.

Lastly, everything i said here are based on assumptions, you might want to request for a proper energy audit from your installer and do not leave anything.

Thanks for reasonably investing the time

Infrared cooker is a modern hot plate with glowing heating element that can obviously be seen.

Induction cooker: You see nothing. Everything is black. You hear it working only when the right pot is on it.

Wrong pot , No work
Right pot, working


Una question for here enh...
YouTube and Google dey o

then I'll go for infrared cooker to avoid pot selection.. hope the infrared no dey chop light too like the normal hot plate

Bryanluke:

Are you aware that when you use Google to make researches, you end up gaining much more knowledge than you would get in here most times ?

At end of the day, except you after using way less energy, you are free to use any kinda cooker whether infraRed, blueTooth, induction, etc

Coming from someone that own and used infared and induction cooker, I will pick an induction cooker anyday anytime over an infared cooker. What i like most about induction cooker is the speed at which it cooks, It saves more energy than infared cooker…i got few set of stainless pot at a local store here that works with induction cooker at a ridiculous cheap price…4 sets for about 20k.

Choosing induction cooker is a no-brainer.

The only viable argument against it should be for someone who already has pots which have no magnetic base. Even then, it should be about budget, as it's no fault of the cooker.

No one has talked about the heat infrared and other electric cookers generate while in use. There is little or no heat lost to the environment (kitchen) while using induction cookers as energy is directly transfered to the cookware (pot) via magnetic field.

if stainless pot work with. That's all I have then

I took a small magnet or in my own case i took a common earpiece (most earpiece generally have small magnet inside) to the market, i simply stick the magnet to the body(and the base too) of the stainless steel pot and it STICKS or say they attracts each other, That’s when i know it will work with induction cooker because there are fake stainless steel pot out there that don’t stick, Kindly note that.

I'll look for a magnet to test the one I have at home

That they don't stick doesn't necessarily mean they're FAKE

But are they going to work without being magnetic

zenith4biz:

what I meant is not all stainless steel are magnetic. Wasn't even aware of using stainless steel till my aunt who took one of ma induction cookers pointed that out. She probably figured that out by mistake. Then after using a couple, we realized not all work. A Google searchfurther pointed out why.

Okay, mine only works with stainless steel pot that is magnetic, so I do test with magnet before any purchase

Do jinko panels come in individual packs?
I'm asking because someone said a pack usually contains more than one panel.

I will always prefer and recommend a good infrared cooker to induction cooker for good reasons. Meanwhile, can you share the pic of your own infrared cooker.

leTrizzle:

It comes in pallets.

The number per pallet varies between 27 and 37, depending on the exact model and frame thickness.

If you see Jinko panels packed in cartons singly or in twos, know that this was either done by the seller or it is definitely not the real deal.

From your fault description above, the bold line is not quite clear to me can you share the pic of the said SPDs for better clarity.

Hello house,

Please I am planning a 24v (3-3.5kva) and about 5kwh lithium system and would need advice on.

1. Best 5kwh lithium system I can get and cost

2. Good inverter to get. Either Hybrid or with MPPT

3. How panels and size

Budget is 2m and dont know if it can go

Honest advice will be appreciated

Since you are buying a 5kWh battery, I highly recommend getting a 48V system instead of a 24V one. The reason is simple: it's much easier to over-panel with 48V on the same charge controller capacity.

Your budget may need to be increased slightly.

For the battery, I’d recommend a Deye, Deriy, or Valto or Mr Reed's battery. For the inverter, I’d recommend a Growatt-either a 5kVA or 6kVA model.


4 to 6nos of between 500-620w panels should do the job.

Thanks brother. You really went to town on this one for my sake.

Once again thank you.

What sizes of wires would you recommend?

Are Fouani store solar equipments trusted here. Their Deye battery and inverter? Anyone has had a bad experience with them?

Good evening Solar gurus in the house please I have a question. If someone installs a 6kva inverter, some panels and some batteries, can a 5.5,KVA generator recharge the solar? Because the installer is saying it can't

Stormyweather:

This will depend on your charging current and what ever appliance u will be running while charging.. lets say u are charging @ 30a, you are pulling roughly 1kw+ from your gen. You can as well power another 1.5k-2kw load on the same gen. You can still increase your charging current while running a lesser load and vice versa. Note ur inveter should be switched off at this point. Just be careful not to abuse ur gen power..Another thing is your gen frequency should match your inveter frequency requirement

To have a smooth experience go for a higher rated Gen. But if you have the Gen already, set the right current and turn off almost everything in your house while charging your battery.

For example if you are charging at 30amps and 28volts it’s roughly 1kwh draw from your Generator per hour. But imagine you turn on all your load at the same time while you are charging your system, your gen go just dey off.

Perhaps your installer have considered all those factors and your setup and came to that conclusion that it won’t work.
