We recently met this 65inch plasma at a site . Client says this TV set cost him real money some 4 years ago & he isn't willing to let go .. This isn't the 1st site we're experiencing this as most don't really know plasma tv are energy guzzlers .. We see some clients who don't believe in just changing a working electronic and that's partly a major challenge we do face sometimes in renewable energy quotes & installation. Later some will say 2 battery system didn't last long with just TV on .. It's well !!

This is more than my total consumption which includes my fridge and freezer plus ofcourse a 50" TV (without the AC etc)

And not just that. Okay, assuming by some fluke other than Low Voltage Disconnect, the BMS trips off due to maybe something like High voltage protection or short circuit protection and this happens when the sun is high up in the sky, then your CC can get fried.

Those scenario here does not shut the battery down like in the low voltage disconnect.

Thanks. I did chat the guy up and the downside was that requirement of grid to boost back the BMS in case it trips. My current pack isn't like that and the manufacturer indicated that it can be connected in series.

Yup, though I think if high current from sunlight can't wake up the BMS then I don't see how utility will do that, unfortunately I am off-grid so can't test that out. What's the specs of your bank and price?

Hello gurus in the house I need your view, I have a Camry 2003 am not sure if it consumes fuel. I buy 5k fuel and use for a week from Sobo egbeda to opebi ikeja. What do u think, does the car consume fuel

You can use 5k within few hours or even for a month, it won't determine if it consumes fuel. How many miles did it serve, what's your driving pattern, any fault codes on the car etc are factors that could help

You can hit up to 2.5v per cell with no issue ie 10v without issue if it's a 3.2v lifepo4 cell.

Yes you can but I don't want to....I like to keep my usage within 90% and 10% DoD. Actually once your battery is below 3.12v per cell you would have already taken out over 80% of the juice in the battery.

Do you MANUALLY have to reset the BMS? I presume a low voltage cutoff means the system shuts down due to battery being disconnected to inverter. In an Axpert type of inverter system, the inbuilt CC depends on battery being available to power on and I connot but imagine the possibility that the sun will be shining and my system will be sitting dead while I am at work. Or is there something I am missing here

There are 2 things here:

1. Low voltage protect of the BMS, if and when this happens the BMS shutdown power from going out of the battery hence your inverter won't even come on. The idea is for you not to get to that stage by doing point 2 below, but if it happens, the reset button or hoping that a high solar current will be sufficient to wake up the BMS are the options

2. Voltage cut-off by the inverter, if this happens then no issues as the inverter is what has stopped output hence your battery still have juice in it and will be ready to receive charge whenever it comes up. I recommend this and currently have mine set to 24v.... unfortunately that is the highest cut-off voltage that I can set on my inverter (and I think this is applicable to most inverters).

Thanks for the clarification. How many hrs does it take to full charge?

It really depends on the charge rate since the rate for solar is not constant, but assuming charging from low status, typically within 8hrs if charging at minimum of 20A

I don't think so. The BMS used in that seems to be different from the type that can be connected in series. There is also another peculiarity of the BMS that I don't seem to get down with; something that has to do with "only grid power (and not solar) can start the BMS when it shuts off due to low voltage protection"

Maybe Ojeysky can shed more light on those, since he has been using that product for sometime now.

No it can't be connected in series. It can be powered by solar if you can get high amps from it. If the BMS trips due to low battery, don't reset the BMS until you have reasonable hervest (at least 5 to 10A), am off-grid and that's what I do everytime I have had a BMS trip. That said, it's better to avoid getting that low in the first place :-)

Okay. Thanks. 39 watts at lowest speed for a 16 inches fan is still on the high side in my opinion.

We agree

Can it be connected in series to make a 48v system?

No but the guy has a 48v 150AH option, I think that one is 550k

Okay. Thanks.

Is it strictly AC or AC/DC?
Are you able to measure the exact consumption using a measuring device, you can help by indicating the exact consumption or at least the rating printed on its label.

AC and it's rated 50w but consumption when measured is between 49 to 39w from high to low speed.

JUMIA IS 16k and 12k respectively..all with remote, tot the mighty alaba will be a lot cheaper.
i saw a cheaper one at 9k on jumia last week, quickly placed order, but order was cancelled by seller after 4days

@valto , i want ac, wouldnt mind dc, if it has an ac/dc adapter

Kindly share reference to the ones you found....guess am not digging Jumia well enough

Okay. I found it on Jumia, even added it to cart. But sha it isn't indicated if it's DC or AC. Also the consumption is not written on the spec sheet.

But since you've ordered, please do carry is along on your experience.

Don't buy it sad

Edit: Since I have now used it for a day, I can actually say it's not so bad just that the quality isn't there..... and not every part fits well together. There is also no much power consumption difference between the fan speeds.

Yes it doesn't.
Tried all permutations and combinations still error persisted.
Am still using it on battery now and everything is powered just fine but I want to get the error message cleared and also the possible cause

Could there be a way to reset the inverter memory or something as this error prompt could also be an error

There was a time I used that kind of inverter before I transferred it to my Bro, the charger indicator stopped blinking when charging but since every other thing seem to work fine. I just kept firing the thing and it's still serving to date. So if all is fine with its operation just no worry much wink

chai, na this fan jumia de sell 8000 .. go to alaba int and get it for 5500 or any local electronic shops and get it for 6500

So there is no scenario where the maintenance error goes off?

True and this is still valid up till now. I have just secured my BMV 712 (and by the way I happen to have extra BMVs which should get to me sometime next month, if anyone is interested to buy you can pm me).

Problem not solved

Inverter still works fine.
Charges battery with power supply
And still powers all my appliances
But shows the Service Assistance indicator light

You may need to troubleshoot with various scenarios:

1. What happens if you disconnect solar
2. What happens if you disconnect utility charging source
3. What happens if you disconnect inverter output load

Looks good for when I become OPEC chairman

How about the local guy? I want something in smaller units, like 12V to play with if he can make such or 24V

Lol.... that is just the price of a plyontech 2000 yet you get double the capacity of a plyontech (disclaimer: only focusing on capacity and cost, not the bells and packaging).
You can reach the local guy, he certain couples 12, 24v, 48v variants at reasonable prices. Here is his number:

This guy is good too, I know someone who bought from him and there's no complaint till date, ojesky can also testify too

The image did not display but I guess you are referring to the same guy? Yes indeed. My personal quest for DIY is because I want a BMS that can provide me status of each cells. I have also recommended it to him, hopefully he will add it in future.

That's right to some degree, but even then he still need to add a little more unless he plans 100% DoD which is not recommended even for Lithium.

The way I compare it. 100% DOD lithium is 50% lead acid and 80% dod lithium is 30% lead acid
