MontyNG:
What are my options for a 48v LiFePO4 battery. I want to explore local suppliers before I consider importing it myself.

Also, will you be happy for me to test the capacity so make sure the tested capacity is the advertised capacity...
For example, I have witnessed situations where a 10KWh battery (48v/200ah) battery was tested to only have 7KWh

Cheers

Valto:
u are better off importing yourself, as i doubt any seller will agree to go that route with you.

Hi,

Good thing you want to go the lithium way,

As par local suppliers ojesky gave a suggestion to this in one of his earlier post, about those who import and couple cells locally, you might want to engage them to get what best suits you as they might give you the freedom of testing ....

Or

You can buy several known brands locally available like Pylontech of different energy variant, BYD, BSLBATT, Dryness and others ... These you get what their spec sheet states.

Hello everyone, please can you suggest a solar system (including brands of inverter and battery) for me with the following load

Standing fan (92 watt)
Bulbs (5 watt x 8 )
32" TV (60 watt)
Sound system (60 watt)
Bruhm freezer (I am not sure of the wattage but on checking the back of the freezer, there is a stated energy consumption of 1.201kwh/24hrs) I will attach a picture of the freezer

Looking at back up time of 5 hours

SuleimanKano:

Inverter 2kva 24V Genus/Synergy/Equivalent
2 Unit of 200/230Ah Tubular/Lead Battery
6 Unit of 300W Solar Panel (wired in parallel)
60A Mppt Solar Charge Controller
Battery Rack & Solar Frame
Cables, Breakers & Accessories.
Cheers

Considering your load, your freezer should be put off by 3-4pm so you can have the desired 5 hrs back up.

Can I ask why the six units of 300w PV have to be wired in parallel?

MontyNG:
Thanks. I've been seeing different brands... I saw pylon tech, felicity, and blue cloud.

Still researching

Do you have contacts of folks who assemble locally?

Standing fan (92 watt) - If Ox fan ( you can get DC fans of around 20W max each ) to replace this one
Bulbs (5 watt x 8 )
32" TV (60 watt) - If your TV has Eco setting in display setting, then you reduce consumption further
Sound system (60 watt) -
Bruhm freezer (I am not sure of the wattage but on checking the back of the freezer, there is a stated energy consumption of 1.201kwh/24hrs) I will attach a picture of the freezer - 1201Wh/24h = ~51W ( lets say 150W Max.)

Looking at back up time of 5 hours

Yes
Is the price negotiable?
No price is firm Sir/Ma
Does the price include shipping?
No it doesn't, but I can waybill to any part of the country at buyer's cost.

Voltage of System (24)=Inverter=Controller

OCTAVO:

This is quite nice. If she cooks from 7am - 8am (which is 1hr), depending on burner used, she would have pulled 1.8kwh or 1.2kwh from your batteries, which will be replaced by your solar arrays when the sun shines.
I used to think Lithium battery is the only ideal solution for Electric cooker. It's nice to know there is more to explore.

earthrealm:


3kw load for cooking on only 4 tubular batts isnt good. the batteries will likely fail prematurely and not go past 3yrs.

edit, i read where u said you use only 1 burner ..if so.. can i assume thats 1500w?. thats still a bit heavy for the batts...and cooking for that matter which could go on for an hour or 2. you stand a better chance pulling such loads on pressing iron or microwave, since they are intermittent, and last 5 to 10 mins max, my microwave pulls about 1700w at peak..and i ran same on 4 tubular batteries, which lasted about 5yrs

soladavies:


Please can I run this on Nepa charging, I have averagely light of 4 to 7hrs daily, if yes, I will like to have the cost of the set up

SaintOzone:
Please I am new to solar, what solar system will carry my TV 100watts, decoder 20watts, 4 bulb (3 watt) for 4 hours at low cost

MontyNG:


2x 300watt panels
1kva inverter
1x 12v 100ah battery (LiFePO4) or 1x 12v 200Ah battery (lead battery)

MontyNG:
Can anyone help me with the installation and configuration of WatchPower software... Preferably on a raspberry pi. I'm based in Lagos and we can negotiate payment.
My (hybrid) inverter has all the necessary data ports

I'm also open to better monitoring software to watch power if available

olopan:
Hi
if you can make your loads more efficient in bold, you can get a better run hour/back-up time

If you run your refrigeration during day hours, then you have a more backup time to run other things at night

I can share with you a form/doc to know your usage pattern which will stand as real-time reference to prevent a poorly designed solution for you

I wouldn't mind to have one please

Please house, I need advice on the type of battery to get with a 350watts solar panel, that will serve me for at least 12 hours on 250watts/hour. And is tokunbo network batteries advisable to buy?
