How do I confirm this is 314ah lifepo4? These are batteries from Valto.

Did you you tamper with the BMS settings?Call Valto,he will send the correct settings to you.

Its not a big issue

Penuelseun:
Must 100a cc s up to 250v

Depends. Most are 160v. Felicity are around 160v.

Advantage of

Haykay2001:
Get MUST they have high voltage cc

Edit.. I no even no say someone done already suggest am for you.. ✌️

Using high voltage controllers saves you money on the cable sizing. You can use smaller diameter cables in your project. Also less voltage drop for long cable runs.

Go with Scanfrost. I have a non inverter 250L Scanfrost freezer that draws a maximum of 160w. Freezer keeps everything frozen all day long after running for 8 hours daily (8am to 4pm)

I agree. I use this too and its awesome. Avoid the inverter compressor though

why do suggest avoiding the inverter compressor?

Must new model LG and Samsung Fridge/Freezers come with inverter compressors.

[quote author=Dam5reey1 post=135291940]This guy is also sitting down here doing absolutely nothing.. I only Cycled 3 trice or so.

I will top balance it.. any one interested.. 160k

My brother,personally I liike to keep things simple.Personal experience with inverter freezer don show me shege.I prefer the old,conventional manual compressor freezer type.After all the power consumption for me is okay .

This is too much money. You can buy POWMR POW-48140A for around $260 (400k). Voc is around 500v (48v 140amps). I ordered 10 for my project.
Another cheap option is to buy a 5kv felicity hybrid inverter and use it as a charge controller. I believe Voc is around 500v

He asked for a charge controller. If he asked for an inverter the list is as long as the golden gate bridge.

I just dey put some things up jare. LFP wey I dey study daily since it got it 4 years. People go come dey quote AI or website that are trying to protect Dem self from warranty claims and all.

So they will recommend you to use their products like Eggs..

Good evening everyone.
Thank you all for the great information being shared here. It means a lot.

Please I need help. I believe most of us here either use inverter freezers or have an idea of it. I want to get either thermocool 219L or Scanfrost 230L inverter freezers but I don’t know which will serve me better. Any experience from here will be highly appreciated.

Thank you so much🙏🏼

I use thermocool 219 white and it's been performing.

So assuming I want to do 12 kilowatts, this means I will need 2 of this.

Is there any issue with connecting several MPPTs to the same battery bank?

I have been using the skyrun fridge for about 5 years now and also been using it with my inverter for over a year now. It consumes around 100w and even when I put it off around 11pm at night, the things in the freezer remain frozen even in the afternoon the next day

Hello Boss,

Why is one of the battery showing red?

Thank you

Ok. That's cool.

Red temporarily indicates the cell with the lowest voltage. This is dynamic and changes as the active balancing is in progress.

Nteogwuija:
So I made a post yesterday, where I said that I moved my solar mount to a different location and I was getting around 700w as against 500w.

Well, it seems that'd be the first and, I hope it's not, the last time I'd get such output.

I noticed today, as the sun was high, when it's closer to 600w, it goes back down to around 27w and then gets back to 600w, as long as the sun's intensity stayed the same. It's just like a loop. It normalizes where the production is around 577w and below.

So I'm suspecting that PowMr might have overstated the PV's maximum capacity of the 12v at 720w, when in reality it's just 600w.

I might be wrong, though. It's just my layman observation. Maybe the experienced folks can help me understand what actually is going on.

The emboldened is not exactly correct. Infact, the controller can still output a little above the 720w max for a 12v connection and 1440w for a 24v connection

During my 12v days, I had 4 units of 550w broken s on my roof, but I only connected 2 units in series to my Powmr controller using 6mm2 cables for a distance not more than 25meters.

I frequently hit over 720w at peak sunny periods. First attached picture shows the controller doing 762w on one of such days. The other pictures are my broken s. Around same time too, one of us here (Tripple.dots) reported output of over 1500w from hi Powmr controller for a 24v connection.

I suspect you may be having issues with energy losses due to distance from your s to your controller and the size of your cables as well. The originality of your s and how they are connected is also a factor here.

Try disconnecting everything and connecting again. If issue persists and you are in Lagos, you can reach out and we can discuss how we can test with another Powmr controller, just to exclude the possibility of the issue being from there. I will have 6mm2 cables next week, so we can also remove the 4mm2 cables you have there and replace with 6mm2 and observe further. Lax and conditions will apply

OK thank you.

The BMS does this on its own or do we have to manually activate this?

Gurus in the house, which is better in effective cooling system between Panasonic air conditioner and LG air conditioner and which is better in energy efficiency between d two of d same capacity

If you use the same BMS, JK BMS, with active balance function, you can decide to turn on or off the active balance feature.

LG, I may be biased as I use LG.

Their Dual Inverter model is just so energy efficient.

Maximum cold running wattage <= 1000w for the 1HP version (drops to around 600w when room is cold)

Dehumidifier mode = 230w to 600w (depends on time of day; outdoor temperature)

Fan Mode = 120w

My 1.5HP Panasonic Inverter (will find model later) drops to around 650W.

The price between Panasonic n LG is wide, does the huge price difference really worth it in all overall system performance... please help share d manual boss

Good afternoon, house. I am trying to install a DC 12V ceiling fan myself. I need additional cable to connect the regulator to the fan motor. What size of cable should I use for this connect tion to avoid voltage drop?

I'm having same issues o, you know I bought the powmr cc from you.

My cc has never gone above 400w. And i use 4pcs of 420 watts connected in 2p S 2p

Updated:- i changed my DC cables to tokunbo 10mm cables and got this today on 12v powmr cc at just 9am

This information is very true.

I see no reason buying inverter freezer then this scanfrost and even the larger Litres don't consume power as such

That's interesting. Panasonic is always a rugged system.

I'm in Port Harcourt. The PowMr I'm using is different from the one u attached. Mine is the HHJ60-PRO version.

I also don't think it's from the solar s. Sometimes it gets to 600w+ and then drops to 27w and then goes back up again. It does does continously as long as the high sun's intensity is sustained.

However, when the sun drops a little to where the PV production is sustained around 577w and below, that up and down loop no longer occur.

Okay. Can you drop the address?

lol, hisense no get level for AC ...

HeavenlyBang:


My Hisense as well.

swagifted:

That's your opinion. I have An LG dual inverter and a Hisense inverter. Other than the LG working fine with low voltage while the Hisense won't function under ~180v, both ACs perform perfectly fine (cooling and efficiency).

In fact the Hisense is probably more efficient.
