Thanks for keeping this thread alive. It is one of the few most useful for thread in NL.

My major challenge is to charge my laptop, if phone only would have gotten SUNKING product.

Based on your analysis below, what do I need to charge my laptop 65w/90w. Fund is an issue. Battery can be added latter since it will be used in daytime.

Thank you.

Obnoxious2001:


There are inverters that operate on direct DC from solar panel but they are expensive and require a large array of solar panel to function properly (150v upward, with current ranging from 7A upwards) they are called grid-tie inverters

For your shop, you are better off getting more solar panels since most of the usage will be in the day time.

Besides panel are more cheaper compared to batteries.

Below is a picture of how a grid tie inverter looks like.

When I say battery can be added later, I mean the actual deep cycle battery can be added later..

Since you are on a very tight budget.

250W solar panel
75amps battery
30a solar charge controller
Inverter
Wire
This is basically what u will need.

Ok.

Please do you have an idea of the cost

30a controller 7k

75ah battery 50k-55k range
Inverter 20k For modified sine wave
32k for pure sine wave
Wire location determines but budget 1800/yard for 6mm

the inverter watts can't be more than 1000 watts. And what total loads can't this power

Maybe interested in the MPS 3 Pro (55ah).

What item(s) can it power and for how long!
2. Can it be charged with Solar panel?
3. If yes to 2 above, what wattage if the solar panel is ideal?
4. What other accessories will be required as it will be strictly charged by the sun
5. What's the cost?
6. I am in Akwa Ibom State.

Thanks for your interest sir!
MPS 2 Pro is 660wh; that means it can power 50watt of about 10hours, for example it powers 49inch Lg Tv and Decoder for about 7 hours

Yes it can be recharged by 2 units of 150watt panel

Charge controller; 30A will do

130k for battery only

Can be delivered to anywhere in Nigeria

Pls i need your input: i want to buy 2.5kva/24v inverter pls recommend for me budget 150- 160k.,
Also i want to buy 2 inverter battery for the 2.5kva... budget 300k pls is there any good battery of 220ah for that price or i should go for 150ah battery (luminous).
Thank you.

Pls how good is starplus battery for 145k and Afriipower for 173k? Any better option?

Buy Lithium battery, that is what i sell, the difference is too much

Fapemz:

Price pls

This is my current setup

1kva 12v Mercury Direct Inverter/UPS

12v 100ah Battery

I charge it from wall socket via phcn/gen.

I want to switch to Solar and I want the solar to power my load during the day while or after charging my battery.

Heres my load

1. 170w laptop
2. 60w tripod light
3. 24watt fan
4. 100 watt for miscellaneous (phone charging etc.)

Note all of this will not be on power at the same time.
Max, 1,2 and 3 load will be on power, making 254 watt max load simultaneously.

Q1. Can a 300-350watt mono solar panel power this during the day while charging my battery?

Q2. If the solar panel cannot power 250watt load, will the load fall to my inverter and battery whilst they continue recharging from solar?

Note: The mercury direct inverter/ups has inbuilt charger that charges my battery when plugged into a wall socket for phcn/generator

conversation between me and some selling and installing solar inverter system in my area, it's look cheap but I was worried about it capacity

fatherbeeman:

Price pls

From 77k to 500k

Price is okay(its within range for a 1kva 100A system)

But generally wire is very expensive now. So my only concern is with the wire.

You can ask him to mention products he plan using it you want to further audit the quality of the the estimate.

He didn't mention somethings like changeover and accessories but there is provision for them from the estimate

fatherbeeman:

I was going to recommend afripower.
For the inverter.

For the battery, starplus isnt a bad option
Just that you have to make provision for a Seperate external charger to charge the batteries (tubular needs deep charging)
You can go for genus of you are considering tubular.

If you want to go solar,
You will be needing 4pcs of 300w to power your load continousky and charge your battery as well. A single 300w will charge a 100ah battery comfortably.

The higher the panel watts, the faster the charge and the higher it's harvest

Advantage is you can run all this load as long as there is sunshine (I used 8hrs as the run time)


2. Yes.
The battery will compensate for the downtime the solar panels will face (it's very minimal and it depends on weather)

Thank you for this response, since I’m on a budget, I’m considering buying only a 300w or 350w panel, PHCN supply will supplement it.

I do not need the Panels to power my load while charging my battery anymore. I only need it to keep my battery charged during the day while I put my load on the inverter which will be connected to same battery.

I guess that makes sense?

Did i also mention my inverter is a inverter/ups, so it has inbuilt charger for electricity charging of any connected battery, it plugs to a wall socket.

@obnoxious2001
I have a 24v 2.5kva hybrid inverter with 2 x 220ah tubular batteries, 60a mppt cc and 6 x 230w Canadian solar panels.
My installer told me I shouldn't allow d battery voltage displayed on the inverter to drop beyond 24.7v.
The inverter also displays usage percentage.
My question is, what are the parameters I should be looking at during usage in order to prolong my inverter system's lifespan?

Thanks in advance

Your battery voltage mostly (I don't want to start mentioning Technical terms)

There is what we call depth of discharge (DoD), this is probably the reason why your installer asked you to stay within range of 24.7v
then charge controller charge rate.

From experience, most inverter has a cut-off of 10.5 very few products like luminous (am not sure) has 11v (it translates to 21v and 22v respectively on a 24v system).

But 24.7 is not yet up to 50%. I attached an image of various system sizes

Yeah it does.
300w is sufficient enough to charge within 5hrs of sunlight

I just don't want to overwhelm or underutilize the system.

he come up with this inverter and battery, I check on the inverter name it's microtek inverter, though the price online is 10,000 cheaper but I am worried about it's late response, I just want to know if the inverter and the battery are good

Yes they are okay.
One advantage of the inverter is, it can easily be fixed in case it has fault.
Carry go.
