The inverter is rated 500w, but you should know most investers have an efficiency rate between 70 - 90 percent.. So the highest load I have connect to it is my blender rated 350w(only mostly during the day or at full charge)

I'm guessing your question is about what devices I connect to the system. It's mainly my laptop 50 w
Rechargeable fan 25w
Phone and other small devices around 20w

I use for about 5 hours( although I don't usually leave my laptop connected once it's full)

So with a 500w inverter, you can plug in any device as it doesn't exceed 350w.

For higher loads, purchase a higher rated inverter 1kv or more. But u should know more loads will consume more power so you have to invest in batteries and ultimately more solar panels.

adibo:


Good evening. Which blender is that? Also, have you tried using it blend beans or hard stuff?

nihinlade:
My Guy 350k is too small.

What you can do to help your self, if you are not totally off grid (meaning that you still usually have power once in a while)

Buy Tubular Battery. One good Tubular Battery should be around 200k, find out how much now.

And buy a good inverter around of around 100k.

Use the remaining 50k to buy wire and run its own outlets and light points. You will still have some change from the 50k.

This is called an inverter system. Charge it with light and generator fully and it can take you 1 or 2 days before it needs recharge with those little appliances. It will reduce fuel consumption.

But you will still need to be recharging with generator if there is no light.

But if you want to stay away from generator for a long time. You need like another 400k to get solar panels and MPPT solar charger.

For example, I just switched on my Generator 3 days ago and that is the first time in 2 months. And it was because that day there was no sunshine and we still put laptop, TV, 4 lightbulbs, 2 fans etc on it.

Since you don't have the money, do inverter system first. Then later look for additional 400k and then connect it to solar system.

In all you will spend around 750k but you can split it into 350k for inverter, continue to use till you have another money for solar charger.

MPPT Solar charger was N155k when I bought. Don't know how much now. Don't buy PWT as someone suggested, you will not like it.

300watt solar panel is around 80k to 90k and you need at least 2. One cannot do it at all.

silento:
I don't know why Nigerians will always come online to lie to scare others , solar get levels
While most people might be correct that your 300k is too low , but it is not totally true

Let's see

12v 150w solar panel is around 50k for my area anambra state but for Lagos it is way cheaper

You will need just three - so that even when small sunshine your battery is full under 3 hours

3 12v 150w panel 50k*3 = 150k

60A pwm controller this is very important you will learn why in future and based on price of 30a it is foolishness that will make you not buy 60A controller

1 60A pwm controller = 28k

1 pure wave inverter 500watts or even lower like 300watts = 30k lower if you see 300watts

Na here it gets a little dicey

Go for 75a or 100a battery
If you go for 100a depending on location u might need extra 20k to 30k
But for 75a battery you won't need extra money

Remember money for wire and to pay installer , circuit breakers are not included


You 300k will get you a well and able doing solar setup that will work well during the day but not that long for night highest 2 to 3 hours in the night

If you want put to 8hours or more in the future just buy one extra panel and 200a battery and add to the setup and you are good to go


No be AI writeup be this na real life experience I have done years back and still doing it

A picture attached below is one I did last year ending total coz was 550k

4panels , 200a battery, 1k inverter , 60a controller
I buy controller and inverter for AliExpress both didn't even cost up to 60k then na for panel and battery these people take chop me

GerogeI:


Yes, that's what we knew previously, that inverters require either a battery or a reference voltage to work. Am not sure why.

But I own a Chinese inverter that will gladly bypass the battery once the Sun is reasonably bright at around 8 -10am. So I now reserve my old dead batteries are for refrigerator in day time, at night - phones and lighting.

leTrizzle:

By "bypass" do you mean it wouldn't charge the batteries?
What can you power with it when it bypasses the batteries?

groundfinger:

With 350k you will get a solar Generator that will carry your basic home Appliances, i am available to guide you more

BigDickProblems:
Good day guys,

I have 350k set aside for solar installation, and I intend to use it for 2 laptops, 2 Fans and my gadgets. That's all. I don't mind just a solar panel and one battery.

Kindly advise me if this is feasible. If yes, Where can I get this stuff. Thanks.

cunny88:

I use Sukhig solar energy system. You can find it on online

lemme see picture and spec of this.........

matify83:


You may just be the one edging op to self destruction.

I'm perplexed that you can say what you just typed.

A PWM charge controller does not have the efficiency of converting excess voltage to charging current like an mppt does.

PWM charge controllers are very poor in charging when devices are used simultaneously unlike mppt chargers.

Also, for the specification @op is requesting for, increasing the voltage or numbers of the panel is a wasted effort because the pwm will reduce it to match the battery voltage and waste the excess hence it's low efficiency.

For op to even use 2-3 panels for a 12v battery on a pwm, they must be connected in parallel to boast current and keep voltage at the level of a single panel or else the pwm will go up in smoke.

With all these considerations, if you still wish @op to go ahead with the obvious "white elephant" project, I wish him safe trip.

I'm totally off grid for 6 years now and I know what's at play here.

olaztek:

Well done boss,
Pls, can I connect 3 300watt panel in parallel to a 60A pwm charge controller without Frying the controller.

GerogeI:


That's why he used a 60A charge controller. At max of 8 amps per panel, in parallel, they add up to 48A. But those 150w panels should be like 5 Amps each.

GerogeI:

A 60A charge controller has power capacity of 60Ax12v=720W,
576W is well under the rated capacity, Moreover those 150 w panels, especially used one will average 3-5Aamps, that's 30A for 6 panels. 48A will be peak performance.

Your concern is not genuine. The system is properly sized. The only complaint is that you cannot expand without replacing the charge controller.

Secondly, if am running such a system (which I did for 3 years with 30A PWM controller and 3 x300w panels before upgrade), I will always favour more panels, above MPPT charge controllers. I only replaced my charge controller when my panels exceeded the capacity, then I had genuine reason to invest in a robust 5kw solar hybrid inverter, which I still run for daytime power only.

Good afternoon, how have you been? I saw that you used 30amps pwm charge controller for 3 x 300w panels
My current set up is 30amps 2 x 170w panels. I am thinking of adding one 430w panel so I can power my 110w freezer during the day. Would you advice to get Mppt charge controller? Or I can stick with my 30amps charge controller based on your experience
12v system

GerogeI:


Buy more panels first. Two 170w is equal to 1nos 300w almost. Your 30 amp can take 3nos 300W at 8 amps each. When you exceed this, buy 1 more to make it up to 120Volts in series, before you buy a large capacity MPPT Charge controller and Inverter, which can last you for years. 120 volts is usually the minimum operating volts for large capacity charge controllers.

Boss, i have a 120Vdc 4000W hybrid inverter, I have connected 4 500W panel (in series). I just got a 1hp inverter AC. I want to use it (during the day). If i am to add new panels (lets say 4), would you suggest in series or parallel?

Its SRNE inverter (24V 3.3Kw) Maximum Vdc is 500V

bankoleabiodun3:


I have a 300W panel (less than 6 months used). I stopped using when i did major upgrade on my inverter system
It is for sale. I also have 60a MPPT charge controller, Alexa voice Inverter system (1.5Kw)

I' new here, but by convention, 300w panels means that volts will be 300/8 giving 37.5x 3 = 112.5, please i'm only trying to learn

Datbadtguy:
You can install a basic solar setup with 350k, but it depends on the exact costs in your area. When I was looking into solar for my home, I found that prices can vary a lot depending on the quality of the equipment and installation. For 2 laptops, 2 fans, and some gadgets, a single panel with a decent battery should be enough, but make sure to check the power consumption of your devices. It's also important to get a reliable inverter and charge controller to manage the power flow efficiently.
