isangjohnson: I wrote Story because you typed about cell capacity that is out of context. I asked a direct question, Just put the answer. which cell are you packing for 12.8V 100AH that is selling for 250K? I was expecting a simple answer which is 50AH cell is sold at a price close to 100AH. and not that it sold at half of the price of 100AH. |
Re: Solar Energy, A Complement To FTA by isangjohnson: 6:27pm On Jun 19 |
Dam5reey:Quality grade B cells with the advertised capacity Sir. If you have any doubt about it, let me know Sir. |
Re: Solar Energy, A Complement To FTA by isangjohnson: 6:33pm On Jun 19 |
Even with the quality grade B cells, sometimes, we built an average HDF plywood box with daly smart bms, normal battery terminals, a small display for people who are struggling to raise cash. We shouldn't be looking for huge profit every time. 5 Likes |

isangjohnson:Yeah. I did same just one week after installing my inverter and almost regretted it. Now the nepa is there but I just moved the changeover switch that connects to it to that of Nepa to neutral. I had no need for it in the first place because my 200ah battery, even after 12-16 hours of use through evening and night always remain an average of 120ah. |

Dam5reey:It’s an 800va solar generator, with 30A controller. 2 panels (180W x 2 ), 2 batteries (100ah x 2). Highest load it carries is a 60W inverter LG fridge. It never overloads. It charges only with panels and doesn’t charge well with Nepa… I still wonder why it would get spoilt like that for no reason |

osayuwamwen: I see a lot of people discuss their challenges with lightning induced electrical surges. Let me start by saying I am in no way an expert on this subject. You still need to reach out to experts and read on your own so this should not be considered a professional advise more a how "I" did it. Another thing to get out of the way is. no amount of protection help you in case of a direct lightning attack.. No amount of SPD or surge protectors. A direct lightning takes almost everything. Fortunately direct lightning are very rare events, what we see mostly are caused by indirect lightning or near by lightning which is what and SPD and lightning protection system can help with. What are surges. Surges in a system can occur from the grid (NEPA) and most electrical surges comes from the grid.. usually caused by heavy machinery used in a near by house or factory or heavy equipment like fridge and freezers. They introduce spike into your circuit. Surges can also be caused by induced or sudden increase or spike in voltage / current caused by a near by lightning stike. Such a spike which is called a surge can be very high.. as high as 50kvA to 80kvA. This sudden spike occurs very quickly.. sometimes less than a second.. hence they are usually caused transient electrical surges.. they happen within seconds and dissipate. But they can do damages to electrical equipment within the time they occur. Like all electricity, Surges are looking for ground and the best way to protect your equipment is to provide a pathway to ground. Ground here means your mean house earthing. This is why earthing is very very important and it is the bedrock which lightning protection should be based. Check my last couple of posts on earthing and best practice I followed and how you can check your earth resistance to confirm that it is within spec How can indirect lightning ingress into your house. Mainly through external fixtures which are linked to your electrical circuit. It could be a satellite dish, or a solar panel, or a cable from the grid. (Nepa connection) all of the listed are can pick up surges induced by near by lightning and bring them into your home. Protection in layers There is no one red button that will protect your house from lightning. the best approach to guaranty you survive a lightning surge is to take protection in layers. SPD or surge protection device helps to protection against all electrical surge by drawing the surge to itself and sending it to ground (your earth rod) and away from your sensitive equipment. SPD are rated in Type. Type 1,2 and 3 Type 1 SPD Type 1 are usually installed at the entry point to your house. like by the NEPA connection ingress to your house. or by your PV combiner box before it goes into your inverter / charge controller. They are the most powerful and are designed with withstand very large surges.. between 50kVA to 100kVA. The take this large surge and clamp it down to a lower surge like 2.5kva, sending the rest to ground. of cause 2.5kva is still too much for most of your equipment.. this is where a Type 2 comes in. Type 2 surge protector are not as powerful as a type 1 and they can handle surges between 40k to 10kva and clamp it down to like 1.1 to 800va .. much safer.. ideally in a well coordinated setup. Type 2 pick up from type 1 or type 1 hands over to type 1 to further clamp down the surge to a safer level. Type 2 are usually installed in your main house distribution box often time paired with the main house breaker. It should be known that a surge protector should always be paired with an appropriately sized circuit breaker. The surge circuit breaker and earthing work hand in hand. When there is a powerful surge, the SPD trips the breaker and sends the surge to ground. Type 3 are like your normal APC surge protector power outlets you see in electrical shops and super markets. They handle smaller surges and break it down further for your device. Things to watch out for when getting a surge protector - (Ue)The rated voltage. This is the amount of voltage that is allowed to pass through the surge protector. Anything high than that will be shunted down to earth. You want to appropriately size your surge protector so that the rated voltage is just above the rated voltage of the protected circuit. e.g for AC circuit, a 350v or 300v surge protector is ideal if you get an 800v surge protector.. you are letting in way too much surge into your equipment. Remember spd acts like a capacitor, they help protect your equipment from voltage spikes. This spikes happen all the time and often time equipment are designed to handle them but each spike as stress you want to protect your equipment from. ( Imax)Maximum discharge current. This is the maximum amount of current an SPD can protect it can be 40kA or high or lesser depending on the class / type Max protection level (Up) This is the voltage surge protector would clamp down the surge to. It can be 1.4kV or 1.5kv All the above specs are important in setting up your surge protection device. There is so much to say and write about surge protection. Again not a professional and not qualified to give advise on this. But hope this guide people on how to think around surge protection. cheers 9 Likes 2 Shares |

Just to add to my post above. The SPD I use for my setup are 300v DC Midnite SPD for my 2 PV array. They are connected in series with my PV combiner box. The PV as a VOC of about 150v hence the closest rated Midnite SPD was their 300v series. I got it from amazon US For the AC I use Schneider Type 2 SPD sold from the official schneider shop herehttps:///product/iprd40r-modular-surge-arrester-1p-n-350v-with-remote-transfert-a9l40501-5935598 They also have a type 1 spd https:///product/schneider-electric-iprd65r-modular-surge-arrester-1p-n-350v-with-remote-transfert-a9l65501-5935603 Just note that you are as good as your weakest point. There is a lot to know and understand about SPD how they are installed and such. You can reach out to people who have good understanding of them to ensure your setup is apt otherwise you will just be wasting money. 2 Likes |

osayuwamwen: This looks like an off-grid unit. I run an off-grid unit as well ( about 2 yrs and running) and I haven't had any thunderstorm issues. Someone earlier stated that if your system is purely off-grid, you MAY have some immunity from lightening strikes. My rig is not earthed, and my house earthing seems compromised, but so far so good. I have a knife switch that I physically use to change to grid if I need to. |

icjunior: When tubular batteries go bad, usually the irreversible chemical in on the plates not the electrolyte. It is not advisable to change electrolyte of a used battery, you rather top up with distilled water as the case may be. Did your friend observe the 50% DoD rule? Where the batteries charging well while in use? How far gone where they before he purchased them. My advise is to sell them off as scrap, add money and get lithium batteries. 1 Like |

ti4c: You are wasting scarce funds. For your needs, I'll suggest you get a power bank. DC power is more efficient and lithium batteries do the job better for this use case. All your loads are DC powered, so why waste power with an inverter in the mix? 1 Like |

osayuwamwen: Breakers monitor current. Lightening strikes usually have astronomically high voltages and current. But I think it's the high voltage that does the damage. |
