You will need 4 12v 220a lead acid battery to make 10.5kw and not 10kwh.

Milito:
Hello guys,

Kindly assist. How many 200amps battery can give 10kWh?

Beware of breakers you buy in the market

Can you explain a bit more on this heat tolerance issue and why that was a deciding factor for you ? Is it that major of a differentiator when choosing between those range of panels (JA Solar, Jinko, Trina) ?

It's part of the specs of every solar panel from a reliable source. It is called heat coefficient. It basically tells how much power of a PV is lost due to heat.

Panels output at rated at 25° temperature which is rarely obtainable on the field / roof. Hence PV makers include a data that tells how much power is lost for ever degree above 25° the panel is used at.

My former Yingli panel had a temp coefficient of 0.42%

This meant 0.42% of the rated power is lost for every degree above 25C.

The Canadian solar has a coefficient of 0.34%. It was the lowest of all the PV I reviewed. (Jinko, JA, Longi) but the difference was very small. All where within the 0.3% range. CS was just the lowest.

NiyiOmoIyunade:
There is an algorithm called Energy Storage System (ESS) on the Victron side that prioritises solar and battery usage over grid. Grid is essentially a tap that can be opened full throttle or restricted as the user wishes - you could be running 3000w of loads and only using 120w of grid for example. The grid behaviour is SoC driven and the system can be set not to charge batteries from the grid.

The Axpert and Deye type inverters also have a more coarse algorithm called 'SBU priority' - there are also a couple of other iterations of this scheme. Essentially solar and battery usage come first then you set the low battery voltage level at which the system defaults to back to grid usage.

All these schemes let you manage your grid usage else with a basic inverter, grid is being used to run all loads and charge battery even when solar is available and sufficient at that time window which is a terrible waste. People manually switch off the mains or use a battery sensing relay + contactor to disconnect mains as they see fit.

One area where the Victron ESS excels is that you can set a miserly use of PHCN units and simultaneously set the system to very greedily gobble up available energy if your Gen is on - you get the best of both worlds as well as the ability to adjust these settings on the fly.

Here we go... Very apt point here... Again, I remember talking to you privately on the "power" of the 80ams mppt I got... It also has the algorithm power to Control my "non-smart" inverter as you have described... It's called Ashapower. With this, I can set some special parameters like panels over grid or otherwise, I can shutdown grid completely, I can set parameters for float, agitate, equalize etc becos the supply of grid to the inverter is connected via the mppt... I have shared the data sheet somewhere behind... To be honest, this CC is as great as those high end inverters...

Thanks you for always coming through with what's obtainable on other inverters.. Just wondering how much trials u have done with all these big names... 😂

Moneyboyz:


That's why generator comes in handy, I only use that to pump water if the weather is bad. I don't have any wires linked to the grid at all. Nigeria should hold their light.

My brother I no get money give generator repairer again. I have not switch my gen in the last 2years. My generator repairer was crying bitterly I don't call him again. And I told for what, I have constant light. I sold 2 of my generators and left a small one for remembrance sake .

I got one of this but the 100a. Ordinary 43a from CC passed through it n it started melting. Didn't notice it on time cause it been over a week I installed it. I was just lucky to b at home to witness it. Maybe d MCB could av catch fire

These people should be sued. I swear.

@milito
But this 10kWh lead acid will be just about 5kWh at 50% DoD.

This was why I spent half a day buying a genuine RCCB.

Will share all the steps and the full story by weekend

it is actually worse than that

Merlin Gerin was bought over and absorbed by schneider years ago

same way they were still selling Tenby in the market after the company was also absorbed

i can only imagine the nonsense story the Arrow selling it to you will still tell you

anyway, if you ove in lag and you want to buy original schneider

dacool1:
Good day house. Anyone here to give personal review of powmr cc?
Which is better? The new model or old model. Thanks

Have you gotten?

Trippledots:


hello guys,
2pcs, 470w, brand new, half cut, original jinko same as above available. #130k/pc
1pc, 370w, brand new but with some cosmetic scurfs on the frame available..#110k/pc
.
.
Any buyer picking all three at once gets a little discount. location is ikotun, Lagos.

SA. Brand new

Yh. 50% DOD is 5kw. 4 LA can't do 5kwh

RipVanWink:







oga, scrap battery don add money, why you never update ya price

Am shocked when i see these figures
maybe he thinks people don't know. some people sha!

So I finally got solar panels.

I am on a budget though.

Can I do Powmr for a MPPT CC?

For now.

My battery bank is made up of 2 No. 24V 200AH batteries.

My panels are 2 No. Jinko 470W.

I will upgrade soon. But I want to cut off PHCN or AEDC as its known in Abuja.

What's the bypass for cumulative daily logging fault of Powmr?

Dam5reey:


Yes, you can connect as much meters as you need,

Just put Shunt in between Solar to the controller and/OR in between Controller and batteries, then connect the meters.

Can I see a circuit diagram of the above please?

And/pictures of the installation?

odimbannamdi:
60A Powmr MPPT Solar Charge Controller available

Price: 61,000 firm. Limited quantity available

DC meter to provide 360-view of the vitals of your inverter system. It comes with 200A shunt.

Price: 10,000 firm

Does the shunt help me get cumulative logging data from Powmr?

Are you the seller that includes MC4 connectors with purchases of Powmr?

FEGEITOK:

No it doesn't. I dont include MC4 connectors with my controllers at the moment.

Your contact for negotiation

Good afternoon all. Please what is the highest wattage monochrystaline solar panel one can get that is 12 Volts?

Gr8teejay:
Good afternoon all. Please what is the highest wattage monochrystaline solar panel one can get that is 12 Volts?

All these 12v, 24v, 48v......pv, how una dey tek identify them?

Best is you get 190/200w with 19/20v vmp and 9/10a imp like 3/4. Get a pwm n parallel them. Use 10mm cable to run ur panel cables.

Basically it depends on number of cells, however you may also use Vmp of the panel to determine the panel voltage.

17V to 19V Vmp is 12V
34V to 38V vmp is 24V
These are most common panels

What roles do the pv voltages really play when designing a system?
I personally do not always pay attention to them. I only focus on other parameters such as Voc and co, watt, company name including purchasing source, etc.

200AH Is now sold ₦35,000

150AH is now sold ₦25,000

But anyways some may not know

Mjolnir:


Could youpost the solution if you know.
Sent email to smk solar about the issue no response. Same as their phoneline i saw online.

Or post smk solar nigeria phone nos you reached them on.

I hv same issue.have dumped the inverter for now. Very useless thing

Not all specs is important as long as you find what you are looking for.

Does this mean that I cannot use (3) 300w panel with VOC of 44.5v on a 12v system with a mptt controller with max panel input of 160v?

toyeoye:


Marketer! You have spoken well actually.
For now na me and my trusty Famicare go dey manually ruff tins until things look up.

LoL ok Mr famicare.

Dam5reey:


Whats the No load consumption and efficiency?

Consumes around 30w
Efficiency 85%
