Alright I'm back although partially. Purpose? To install new solar in my home. This time around I will attach pictures. |

Step1. What do you want to do? For me , it is to power my house. I know you're thinking how many times.!!!. Well , I have running on 12v since over a year without issues. So why repower? So that I can relax well. I started by proving that solar works. |
Re: My Solar Set Up Journey After A Year. Very Cool by eliok(m): 11:13am On Jul 06, 2021 |
What do I need to achieve the goal. Simple. A good battery system. A good controller A good step down converter./ Inverter see them at [b]step down click here get this step up converter too here A good wiring.[/b] 2 Likes |

Starting with battery. We have three types. I love to teach in lay man's language. 1. Car battery known as lead acid. 2. Deep cycle battery 3. Lithium ion battery. Like those found in laptop. Picture attached in this order

Re: My Solar Set Up Journey After A Year. Very Cool by eliok(m): 7:29pm On Jul 06, 2021 |
Deep cycle battery is better than car battery. Lithium ion is better than both. Which battery should I buy? It depends on where you are, how much you have and what you want to power. For example. If all you want to power is a laptop, then choose the easiest battery you can get . If you want to power your shop or house, deep cycle will do. But if you need the best of both worlds, then lithium ion will do . Each has advantage and disadvantage. But lithium is good if you are willing to pay for it. Otherwise, deep cycle is your next choice. For me , I use laptop battery . Which I get from the market. 1 Like |

None of them is cheap. So ask around for pricing. Before you start. Recap! What determined the type of battery you buy is 1. Money 2. Usage 3. Knowledge and durability. |
Re: My Solar Set Up Journey After A Year. Very Cool by eliok(m): 7:59am On Jul 07, 2021 |
Tips when getting a good battery 1. For car battery ask the mechanic. They know the best. 2. For deep cycle, get used toris. Especially from Lagos. Around 50-55k should do. Beware of so many China battery and new ones. 3. For laptop battery. Get brand names like Panasonic, Samsung, LG. And sanyo. Used laptop battery is like okrika, you need to select them. Samsung has many types but they are generally good. Same with other brands. Here is a pic of the popular one attached. 1 Like

eliok:Nice job @op. I would prefer the deep cycle battery. Since I witness how the lithium battery exploded in an inverter that a guy bought from Lagos to power his phone, laptop and bulb, I began to hate it. The fire even burnt part of his legs. The lithium battery really don't like heat. 2 Likes |
Re: My Solar Set Up Journey After A Year. Very Cool by eliok(m): 9:21am On Jul 07, 2021 |
SilentVboy:yes. every day i learn about lithium, the safety precaution is to avoid explosion. |
Re: My Solar Set Up Journey After A Year. Very Cool by eliok(m): 9:23am On Jul 07, 2021 |
What causes this explosion? 1. When it's overcharged 2. When it's overheated. Now how is it possible? When you get excess panel watts. You are suppose to calculate your needs in solar panel for charging. Will explain soon |
Re: My Solar Set Up Journey After A Year. Very Cool by ineaghe(m): 9:43am On Jul 07, 2021 |
SilentVboy: Having a good bms installed prevents this. My lifepo4 batteries cannot exceed 3.5 volts per cell or 100A charge current even if I connect a hugely oversized panel to it. Once it gets to the preprogrammed voltage, the bms will cut off any further current. Lithium batteries gives better value for money and a stress free solar experience any day. Lead acid comes with many wahala and a shorter cycle span unless you can afford premium brands and a hugely oversized battery bank. 3 Likes |

I wanted to make this explanation as simple as possible. When you are boiling water, after you're done, check your heat source. It's likely warm or hot. This happens because you have probably used the stove or gas for long. Now even your gas cylinder can explode. Why? A number of reasons. But can you use gas safely for years ? Yes. Can you use your stove safely for years? Yes. That's how these battery are. Lithium explosion depends on overcharging, thickness of wire used , and the owners knowledge. 2 Likes |
Re: My Solar Set Up Journey After A Year. Very Cool by eliok(m): 9:49am On Jul 07, 2021 |
How do you prevent overcharging? Check your panel connection. Most of our naija tech guys for solar quote panel sizes just for the money. My brother, if you install 5 kilowatts solar. You can safely charge it with 250 watts panel. I know it seems small but it's will do. But many tech will tell you to install 2-3 kilowatts panel. That's overcharging loading. Another thing is that Panel wires should NOT carry too much current. Battery wire to your equipment should be done correctly. Use normal Ac 220v wire if possible. The whole house wire should be good. Because solar sometimes pass current and if your wire is strong no problem. Let me pause here... 1 Like |

I use this wire for panels to controller.

Re: My Solar Set Up Journey After A Year. Very Cool by eliok(m): 1:06pm On Jul 07, 2021 |
And normal nepa wire that has red and black. For battery to house wiring. Please use wires that has color red as positive and blue or black as negative. I have burnt something due to wrong connection. Don't buy wires without these colors. 1 Like

So I ordered for some things I need. Will drop the links here. Electrical components are quite cheap from alieexpress. i bought the following 1. a BMS BOARD FOR LAPTOP CELLS We have 3s bms 12v 6s bms 24v 4s bms 16.8v BATTERY MANAGEMENT *BMS* SYSTEM HERE you can START HERE over at alieexpress to find them i also bought this digital scale see the digital scale |

Went to get some wires recently. As I was about paying, I remember that the wire needs to be colored red and black which means Red= +ve Black = -ve I withdrew becos the said wire carried red and orange. That's enof confusion there. Get wires that carries these insulation color. You will save your self and your house much money. Solar connection does not give electric shock but if it burns your electronic, you will fear. Knowing which is live wire and neutral is good. I look at the colors and match. Solar no dey forgive miswiring . A word is enof 1 Like |

Calculating your power consumption Formula = power is equal to current x voltage. P= IV Always use this formula. P is watts I is Ampere V is voltage. P= IV Every battery you buy has voltage that is our V. current is our I some battery like car battery is 12v 100A. Deep cycle battery can be 12v 20a, or 12v 40a. Lithium ion or what I call laptop battery is 4.2v 2.2a each. You then connect batteries in series or parallel. For example, adding 12volts + 12volts = 24 volts. That's series connection. But 12v 100a battery + 12v 100a battery in parallel will be 12v 200a. So series connection increase voltage. Parallel connection increase current. 1 Like

By the way, get a multimeter ready always. Test everything to make sure it's ok. Don't underate that little device. 1 Like 1 Share |
