Cost is not the only issue, they often develop BMS

They are much improved now. If you have any With BMS issue, i can fix that for you

GistFullGround:
Can you install for me. I can get the materials.

But can you install for me in Benin City & Ibadan, Oyo State?

Let me know, then send me your number!

Check out my previous post, i have something for you

kay29000:


Wow! Thanks a lot for this breakdown. A lot of us are ignorant of this economical alternative power supply. You too much bros. I will work on getting this setup too.

I do have some portable setup on sale too....do check my previous post. Cheers!

airsaylongcome:


BMS. Battery Management System I assume. What is that about?

BMS ensures even charging and discharging of each cell that makes up the battery system. Cheers!

Know anywhere in Lagos I can get Them?

Check out the lithium battery options i have for you!

Obascoetubi:

which battery is good?

lithium battery, You can go almost carefree with them and they won't give up on you

Fapemz:

Where are They?

Quim2:



Where are They?

300wh that can power your laptop for about 10 hours for 55k

480wh, can power pc for more 18hours for 80k

1260wh, can power your pc for 3 days on a single charge, 200k

We also supply them all with intelligent lithium charger that shows red light when charging and green when full as well as laptop connector with multiplug pins

0806..53..1630..7

mention them

Your initial setup (2 batteries and 1300w pv) should be just fine if used appropriately.

Changing the PWM to MPPT on the set up is also a good boost.

BUT: do not add new batteries to the one you have been using, DO NOT TRY IT!

If you are getting 4 new batteries, the your 1300w and 80 Amp controller should do.

I am interested in finding out if a 20 Watts Solar can charge a laptop effectively?

Please I need help professionals

Even with the appropriate controller, I doubt it will give you a good charge. What are the voltage and amperage spec for your laptop?

Just a dell mini laptop

My solar freezer can work with both solar and Nepa light.

My fridge was defrosting yesterday since there was no light for about 12 hours.
I plugged the fridge into the inverter unit and voila! Everything was fine.
I monitored the battery level and it didn't drop as fast as I thought.

So, I am good

Elsueno:


It's waaay cheaper, I have my own set up with two 200ah batteries, my own can charge with both solar & NEPA..I have being using same battery for almost 4 years now, not much decline, but I intend to swap them with new ones when they clock 5

HI bro
I already have 1 200ah battery which I have been using for about 8 months now. No issue.
I wanted to ask, can I add one extra battery now? Someone said I can't. That I just have to buy new 2 ones.

lakefist:


Get solar freezer and stay worry free

Pls recommend anyone for me, I wanna use it for selling of frozen foods

Well......if it's still performing at optimum...then yes...but if not, it might even bring down the new one to its level

Elsueno:

Okay.. The performance is still very good though.
Maybe I just buy two new ones then.

See mine attached. You won't regret avin a solar freezer. It is worth every penny. Mine is Bona.

Yes better, and get very good ones too, enjoy 24 hours free electricity from sunshine

Hey Bros, how much is this

lakefist:

Pls what's the litres and how much is it? And can u pls explain further?

Elsueno:

I currently use Genus tubular battery and is been superb.
Will likely get same, two of it. I will still retain this one but will use it for solely for the mastor bedroom.

femijay8271:

Mine is 168 litres got it 170k alone without battery and solar s.

Mine can use both solar and Nepa with use of adapter.

I better my neighbor generator will power it conveniently.

That's good. Gonna mention u when i need it next year Jan or feb by the grace of God Almighty

Try give update months later

Please can you share your number

I looked around online on jumia, jiji and konga for ranges of 500watt inverters and chargers. After a rigorous check and comparison, I settled for this (picture attached) for 35k.

It is a 2 -in-1 package.( Solar charger / controller + 800va - 500w inverter). So no need for a separate solar controller

Nice setup, so how long does it last (considering the fact you shouldn't run it below 40% of the battery) and what load capacity do you use on it?

Ovaltine:
Your DIY mentality is commendable.
I am sure it wasn't as simple as red to red or black to black but you still nailed it.

The wiring can be neater.
I suppose you ran a continuity test on the whole system and you separated your heavy load via wiring as well. You don't want a visitor to mistakenly plug a 2500w steam iron into your unit.

Oh. I see there is a socket. Does this mean an extension is sending power to your appliances?

I recently did a 3kva 24v PSW Beaver, 2x 200ah 12v Gel Ritar , 2x 300w mono installation.

I had to pay the optional installation fee despite my strong background in electricals. Its just easier to pay experts these days.

Teedeechian:

It lasts as long as 14 hours with about 600 watts constantly on it. This is my minimal load which will take me from sundown to sunrise when the solar will pick it up again.

Does the 600w include your fridge?
How's it holding up?
Cause i think fridge is what's still holding me back should incase Nepa decides not to supply power for like 3 days, and buying solar fridge is not in the plan for now.

The problem is that solar s are not very efficient converting solar to electricity. The best you can get is 23% efficiency which is very bad to be honest. But considering the free availability of solar and potential cost of petrol in the new year, it makes a lot of sense to tap whatever you can from solar.

My own worry is that make state or federal governments no go dey bill people for owning solar s like Lagos was planning to bill people for boreholes

I hope you understand what 'efficiency' means when talking about solar s? Because 23% efficiency is very very good. The efficiency stated on the solar s is not how many watts they can produce. But means the power to size ratio. In simple English it means if 2 s are exactly the same dimensions and one is rated 300w while the other is rated 400w, the later can produce more watts with same form factor hence more 'efficient'. Most good s produce 80% and above of their capacity when installed properly.
