Anyone got link for a very portable 16s lifepo4 BMS with Bluetooth feature?

dollarnaira:


What is your power factor?
Power(watt) = current×voltage×power factor
If u r in the right page of d screen ( cost) den u r correct.

NiyiOmoIyunade:
I recall that the Binatone CoolGuard I got was similarly imaccurate for watt consumption - I tried it vs various meters and known loads and it dissappoonted me each time so I threw it in the bin wherein I keep dissappointments.

Possibly it may prove to be more accurate with larger loads up to or above 1000watts but I never did that test

Valto:
anyone u needs a fully coupled 12v 230ah brand new grade A EVE 230ah lifepo4 lithium battery, should indicate( can be coupled with daly 4S 60A/80A/100A Bluetooth bms, or JBD 4S 120A normal bms.)

TechGeek777:


Am in Benin City not Lagos. What should be the correct settings for 105AH LFP & 230AH LFP like the one @Valto couples?

They both uses "120A JBD bms" as he stated.

FEGEITOK:


Agreed, that it is not about the brand name, but the source of the brand, my research led me to the direct representatives. I got it from the direct representative, and got it installed by a certified installer.

My Panasonic was made in Malaysia, we have have made in China and made in Indonesia. My Diakin is made in India.

That said, I am trying out Daikin having been thoroughly impressed by Japanese technology in Panasonic. Need I say I got a Panasonic blender that has lasted over 15 years and works as new, never been repaired. Daikin is also Japanese.

TechGeek777:


Yes am in the COST screen. Currently laptop reads shows 60.1W @ 207.1V * 0.463A * 0.61PF = 58.5W

I did not check power factor of others with the Meter

Valto:
6s to 21s JBD 150A lifepo4 Bluetooth bms available, daly 200a 16s Bluetooth also available

ceaser:


Okay then. Can't agree less. It appears you did your home work.

Care to give drop the rep address?

Penuelseun:
Absorb should be 13.8v while float should be 13.6v, you can contact their office, they should be able to set the inverter for you before shipping

FEGEITOK:


Can you compare high-end high fidelity audio equipment like Accuphase or the now discontinued Kenwood with the boom boxes sold in our markets today?

Working well.
Note dt frequent usage is advisable to avoid the tiny battery in it go bad.

Talking about boomboxes, this reminds me of my dear Bose Soundlink BT speaker. I have tried to find an equal to it and believe me I haven't been able to find a suitable replacement after spending fortunes on two popular names - Anker and well, Sony dissapointedly.

The Bose was highjacked by my little sister who I can't say no to.

TechGeek777:


Thanks boss, and the seller I purchased it from here few days ago did not tell me this.

Can I easily get spare of the battery if/when it eventually goes bad?

How much does the battery cost?

dollarnaira:


Available on AliExpress as usual

I am just in love with Victron. Victron is amazing . Problem is the price . My 1.6kva victron does wonders . Runs my fridge and freezer, 2 Laptops, lighting points, 55 inches TV, Routers and V-sat and phone charging and more . All less than 50% of its ability.

When I visit another property that I have a 2kva Mikrotec Inverter , just 2 laptops and a tv , the inverter fan kicks in and it starts struggling.

I would rather have an 800w victron Inverter against buying other 1.6kva of other brand

Boss, I got the below readings:

1. LG 32” LED Full HD TV 32LP500BPTA
Energy Saving Watts {
Off (i.e No Energy Saving) = 36.5W
Minimum = 27.5W
Medium = 19.5W
Maximum = 12.5W
}

Note: I put this in energy saving mode and without energy saving (i.e Off) to get above reading

This is link to above tv https://www.fouanistore.com/lg-products/lg-tvs/lg-led-tv-32-inch-lp500bpta-full-hd-led-tv/


2. GOTV = 3.5W
Note: Above is rated 12v 1A


3. LG XBOOM CJ44 480 watts = 10.5W
Note: Official LG website https://www.lg.com/eastafrica/audio-video/lg-CJ44 wrote that the Power Consumption is 80W


4. HP 620 Laptop = 48.7W - 68.5W {
1hr = 0.050KWh (i.e. 50W in one hour)
2hrs = 0.081KWh (i.e. 81W in one hour)
3hrs 37mins = 0.132KWh (i.e. 132W in one hour)
}


5. Qasa 18" Rechargeable Fan = 9.5W
Note: This is rated 33W, but I got 9.5W


6. Scanfrost Steam Iron SFS12304 rated 1100W - 1300W at (220v - 240v), I got 943W

dapsyra:
Try Bang & Olufsen

earthrealm:


I DONT THINK YOU UNDERSTOOD FULLY WHAT YOU ARE SUPPZD TO DO.


you are supposed to plug the load on the 2 different meters you have..and then compare with the devices energy name plate.

example:
Panasonic steam iron 2400w sticker
1. binatone coolguard -- 1800w
2, 2nd meter ------ 2350w

by the time you do this for a series of devices, you would deduce which is closer/accurate.

2ndly at bolded, either you wrote this wrong or understood it wrong

HP 620 Laptop = 48.7W - 68.5W {
1hr = 0.050KWh (i.e. 50W in one hour)
2hrs = 0.081KWh (i.e. 81W in one hour) --------------- if your wattmeter displayed this after 2hours, then you shud divide the kwh by time in hours to get the average consumption, which in this case should be 40.5watts and not 81 watts u wrongly state there, same goes for the other appliances you used wrong maths for there
3hrs 37mins = 0.132KWh (i.e. 132W in one hour)

Penuelseun:
Tbb has voltage editable features, but you will have to go to their office for that, or buy the external console to do that

Eagba:
I just the tbb inverter 1.2 kva , can it work with 200a 12v lifepo4.then the cost of the lifepo4 and best brand. I no know diy for batteries sir

TechGeek777:


I wrote it wrong initially, below are the correct one.

2hrs = 0.081KWh (i.e. 81W in two hours)
3hrs 37mins = 0.132KWh (i.e. 132W in 3 hours 37minutes)

0.132Kwh / 3.37 (i.e 3 hours 37minutes) = 0.040KWh.

From your explanation it means the average consumption is 0.040KWh.

Thanks bro for the enlightenment!

coldcandy:


3 hours 37 minutes IS NOT 3.37
(3.62)

FEGEITOK:


Interesting, I am targeting 8KVA next.

Here is what I found, Schneider is expensive the higher you go.

I found Deye to be much cheaper, but I haven't decided to go that route.

Let's just say I am in love with Schneider.

If you are going for that capacity, I think a 48v system is the way to go.

But I am an enthusiast and not a professional, I am sure they will chip in.

toyeoye:


Good morning. What do you think about this setup for 5kva.
Just your honest thoughts , thank you very much

NiyiOmoIyunade:
Some elements do not add up.

6 units 12v batteries implies a 24v nominal system - when you pair this with 280w x 12 panels for a total of 3,360w of PV, you will be wasting energy/limiting solar production if using an 80A MPPT in 24v nominal - in simple language, the CC can only pass through 80a whereas your panels can easily make 90a to 100a and even more on a good day.

Why are you needing a 5Kva inverter for a 24v setup? Consider your real loads and see if you can get by with a smaller inverter - do an energy audit. The savings can be applied to better system components.

10mm AC cable is way way overspec for a 5kva inverter - you are just wasting good copper. Up to 10Kva, 6mm cable should do.

Very likely 280w panels are low grade knockoffs - most serious PV sellers these days sell 300w and above for their smallest size. Look carefully as panels are one place you want to get right and enjoy them for the next 20+ years.

When I see a quote like this, one can already guess the kind of installer and the final results you will get, consider getting an energy audit and comparative quotes from other installers with proven work and performance history.
