Bargains. Still available.

I am getting on, so I am selling some tools & equipment and materials. All are professional grade and well maintained. Mostly new.. Some slightly used.
Grab a bargain if you see something you like. All items can be sent by waybill, at your additional expense, to the "Lagos motor park" of whatever town or city you live in.
These will be a series of posts.

Jemag in Jos can waybill you a very decent LFP battery bank.
Ritility in Ijebu Ode can waybill you the same, together with a rack kit if you want.

FireTheSun:
I read somewhere on this thread, where someone here bought a Ready-Assembled liFePo4 battery from a Company around Lekki/Epe (Lagos) axis.

Thanks

I think "No worries" on 2 conditions:
1. Each battery bank has its own BMS
2. Both battery packs have similar charge & discharge profiles.
Otherwise the banks may soon become out-of-balance with each other.

smallsmall:
Gurus, one question.

Can one mix together (charging and usage), two battery Banks of,
Any downside, danger?

Consider
1. You can place your solar panels on the ground / carport or on the roof. The property site plan and the roof design should be optimised for maximum solar harvest and for safe access in order to clean the panels.

Telcos already have your bio-metric data and they know the ID of their law-abiding customers as a result of SIM verification exercises.

The NIN exercise is part of the global effort to use your smartphones as the portals for monitoring and controlling all aspects of life, from cashless economy (trace-able e-Naira CBN digital currency), your choice over your own body (mandatory vaccines), movement restrictions (vaccine passport / global travel papers), your wealth or social credit (universal basic income support or taxation), genetic profiling (digital health records), education records, and more. It is part of the UN Agenda 2030, promoted by the World Economic Forum. search online for the sponsors....

lexy2014:


Y the desperation on part of govt for NIN? It's definitely not for d benefit of Nigerians. What are they pursuing?

Valto:
guess it is 32pcs eve 280ah cells.. the 310ah should be CATL...

How far with the next LiFePO4 group buy?
My kidney is ready for harvesting.

mctfopt:


Lishen, CATL, EVE all happen to be in the same WhatsApp group for most DIYers across the world.

I have another question for the house, is anyone here into EV or at least the younger bro electric bicycles/scooter etc? I hope I'm not alone here. Lol.

which Washpap group? kindly share.

Very interested in EVs. These will be the next accomplishment of the solar cadres. All that excess afternoon solar going into your transport!!
Then go bigger, and set up a charging station for your neighbours.

Africa will shock the world with adoption of affordable EV especially bicycles (mountain bike style for all terrain), keke trikes (for commercial taxis), and scooters (for neighborhood runs if you have smooth roads). Let me know if you want to make a business of these.
You are not alone. You are ahead.

Me, I no get money for isho, i dey plan ile-ala ja gogoro!! And not gogoro the Asian battery swap e-bike mobility business, either.

Also interested in 32pcs of the 280Ah LFP cells if price is USD99/pc
I got a (high?) quote of USD550 for 1CBM sea-shipping from China to Lagos port and excluding clearing.
1 CBM is apparently about 80pcs?

So the tally so far seems to be:
1. 48pcs Toluxa1
2. 64 pcs Barezzi
3 32 pcs Remizvxcq
Any one else, please indicate demand fast.

Valto:
u can team up with toluxa1. contact him or me, for heads-up.

In my practical experience, it is best to design on the assumption that 1hp nameplate = 1kW continuous power demand! Some loads need 2x or more of nameplate continuous amperage in order to start/stop. Some loads, when affected by blockages or stalling, can surge up to 6x their continuous load amperage. All these amps are pulled from the batteries via the inverter(s) and cabling. Size to spare.

SolnergyPower:
Please take a look at what a 1.5HP was drawing. 1.4Kw. Any explanation for the difference compared to your calculation?

Expertt:
Good day all, please how many batteries and solar panels can power a 15kw Inverter for 12 hours assuming the total load on the Inverter is 12kw continuously for 12 hours . Note: the load consists of mainly pumps, electric motors and 1kw electric heater. Thanks

Your question calls for professional services. It cannot be adequately addressed in a DIY forum. But we can start.
A well-ventilated inverter runs at internal temperature about 40-65 degrees centigrade. Considering temperature derating and PF, the maximum continuous output at 40degrees is about 61 percent of its nameplate kVa. Your 15kW inverter * 0.61 will carry a continuous load of about 9.15kW. In the first instance, the types of loads you mention tend to cycle on-off, so they stress inverters more and heat it up more, which will lower the power delivery, so expect lower supply for continuous load. In the second instance, your energy storage capacity will determine how long the inverter will supply for.
You mention that the loads are mainly pumps, motors and heaters. Generally, it is advised to not put these HVAC-type loads on solar systems because they usually have start & stop surges current that may be many times their continuous running current. To be conservative, budget 2x or 3x provision for the surge power of the inverter.
You also need to allow for the tare of the inverter system itself.
So your 15kW inverter seems inadequate on its own, your system will need to be expertly built up with solar PV, battery storage, and a backup generator, and solid loads management,

As for number of batteries and solar panels and 12 hours. Presumably you want to carry these loads by solar and storage during daytime?
Batteries: 12kw for 12 hours seems to be straight-forward 144kWh, say 150kWh for system losses, but there's more to worry about.
Allow for some redundancy: 2x for lead acid, 1.5x for lithium. So, 300kWh for lead-acid, 225kWh for LFP.
At 48v nominal, 6250ah lead acid, 4700ah LFP.
Unless you intend to disconnect the loads after the 12 hour shift, then reconnect them before the next 12 hour shift, you will need to provide for their consumption all the time they are connected! You need more batteries.

How many 200ah lead-acid batteries are you going to configure in series-parallel, for your system to be efficient at 48v? 2v 3000ah+ batteries are available if you have a forklift. How will you maintain this battalion of lead-acid batteries? You are in high-voltage lithium territory

Solar
You should plan for the worst month of the year, so assume 4 hours of peak sun hours. All other daylight is a bonus.
There's more mathematics, but to keep this short: You will likely need a backup generator, and diversion loads.

adrusa:


Can people please share their opinion on felicity inverters as to durability, stability and idle consumption. Thank you in anticipation.

Also, please share your actual experience on the Felicity LiFeP04 Energy Storage battery packs. My inquiry with kiekie1 has drawn blanks so far as to availability and pricing. The Ali-Baba website is also sparse on detail. It seems to be 75% usable kWh. Am worried that they are using second-life batteries from retired electric vehicles?

Shuu!!!!

Abeg you dey live for Nigeria? You want to feed the grid in which country?

On ground, in Ogun state.
Many potential opportunities to feed the utility grid (at wholesale level), and into shared micro-grids (at retail level) such as in residential and industrial estates estates, and into private nano-grids created by select inverter-chargers. My system is one such nano-grid.
