Are there no disadvantages of flat roofs, particularly as regards retention of rain water? Do you pics of this kind of roof yo refer to?

Omo...these steep roofs(send down the rain roofs) are really bad for solar generation.
These past few weeks, my battery has barely charged past 45 to 50%. Something that gets to 100% b4 2pm before now. It's seems the sun direction has changed. Now it currently favours North on my roof while my panels are facing south.
The solution now is an expensive solution. I need to install new panels facing north and buy a new charge controller and cables sad

By the way, who sells growatt 120A charge controller. I need one for this upgrade.

Between , hope my lithium battery not charging to 100% daily won't affect it?.
Oh yes they are bad for solar energy generation.

If you have space and money, do a car port or add panels. If the house is yours, plan towards yanking off the roof someday to do the flat 90o south roof style. Then cover all of it with panels.

We went to Europe wey no do see plenty of sun, inherited their roofing style and now we have a need for Solar Energy Advantage, the roof we spent millions in building has become a stumbling block.

A quick hack to the dust issue could be just lying the stab on it's side rather than standing it upright. That is if the heavy coils are well secured inside for that orientation though.

That way dust would take a very long time to settle in the contact surfaces.
LOT OF THINGS MIGHT GO WRONG IF YOU THIS, I WAS EXPECTING SOMEONE TO SAY WE CAN PUT SOME DUST FILTERS ON THE VENTS TO MINIMIZE THE AMOUNT OF DUST IT SUCKS IN.

THIS IS HOW I WAS ABLE TO GET AROUND THE DUST.

Good morning,

My question is off the solar discussion.

I intend to purchase a 5Kva stabilizer to boost the low voltage supply.

I intend to connect it to my Freezer, and TV

My question is should I go for the conventional big century Stabilizer or a wall mounted stabilizer?
What are the differences in terms of durability and performance?
If there a re better brands I could get also, I'd appreciate.

cc: Jonescosmos
For the 5KVA range of stabilizer, Haier Thermocool is your best pick. I have installed more than 50 units for various clients. Both Wall and Desk Mount has the same components.
Both models performs excellently. While the wall mount gives you a nice and clean installation finishing appearance.

Make sure you buy it from Thermocool showrooms directly.

Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by jonescosmos(m): 7:21am On May 23, 2024
I will share with you my personal experience with these servo stabs.

THEY WORK AT THE BEGINING BUT WILL GRADUALLY FAIL.

Yes, they will fail because the movable parts on that huge toroidal coil will interact with the dusts that are settling on the spindle and coil. After a while, the dust might create a short circuit on the surface of the coil and then the stab will start dropping breaker or fuse due to the explosions from the short-circuit.
I have had this issue with more than four different brands, same issue ooo. Service center guys will try to file off the affected surface and it will work well only for the fault to return after a while.
I eventually stopped taking stuff to the service centers and started opening them up first damn the warrantee, see what went wrong and decide if I should go through the hassle of lifting heavy stabs to service center every now and then.
So during my quest, I discovered that DUST IS THE WORSE ENEMY OF A SERVO STAB.

Then I switched to a relay version and I have been using it for more than 5 years and counting without a single issue.

My Advice: If you must do a servo stab, make sure it's dust proof.

So I don't wanna make another terrible error, this time with a central stabilizer. I may need to get one anytime as I was able to secure a prepaid meter that has for a while been installed but not used cos it had some error codes which made me unable to load a key change code and credit. The issue has been resolved. So I discovered the voltage supply is a terrible regular 160v and seldom 180v.

I did some searches and saw Prag, A&E dunamis models (10kva) and another funny name like this (Jor-El) 😁 as in Karl Kent name.

Anyways experienced users should kindly provide some info.

• Which models are tested and trusted? Few days ago, I pulled out about 4 units from storage that I last used about 6 years ago and realised they can't seem to handle the 160v input.

• How durable are these things? I read one of the reviews on Konga where a buyer cursed that the Jor-El he bought didn't last more than 6 months and it stopped working.

• How good are they in protecting appliances? My appliances have been safest on solar for many years now but foraging back into NEPA means I may be courting damage to these appliances from overvoltages, undervoltages and fluctuations.

• Any other questions that I may have missed but that experienced users know will also be welcome.

Thanks as always.

NB: I assume 10kva may suffice for loads which I anticipate may max to around 4kva with future upgrades/addition of appliances.

I also do not intend to hook my inverter AC charging unit to anything NEPA under any conditions whatsoever. It should continue to use the solar charging abeg, to avoid stories that touch.

I've however thought about installing an automatic rapid changeover switch to handle the change from inverter to NEPA whenever the latter gets the seizure brain waves to provide supply.

I understand completely. My intention is to go with what people already have empirical evidences on, as it is tabled here for instance. So dual inverter it'll be. Or maybe even the newer dual inverter type B, as someone has mentioned here.
Oh yes, just mention to them that you want LG Dual Inverter GenCool B that's the latest.

They will know that you have done your research and you know what you want.

From what I've read here, hisense' performance is better than LG's. But I don't think Hisense has at par energy saving options as LG has. I haven't even come across any hisense special names for AC the same way LG has (smart inverter, dual inverter) or Thernocool (Genpal)

Hisense ńa just Hisense. 😊

But it is always way cheaper than LG and thermocool which basically market their already established names. Not just their ACs but most of their appliances.

As per that deal, I hope they find buyer soon jàre. I don't like the way I'm seeing that AC everyday. It makes me mad with myself each time I see it or use it.

If una find anybody wey dey interested sha. I'm even ready to foot the logistics bills to the person.
Just make sure your are not disposing LG Smart Inverter AC to buy Hisense Inverter AC that would be like jumping from frying pan into fire because people can't tell the difference when it comes to Performance against Energy Efficiency, Take for example your Home Theater is powered by I pass my neighbor, you tune up the BASS, your Gen will protest, You reduce BASS and Tune Up Tweeter, Your Gen will smile, after all you will still hear the same music, so why stress the poor GEN?
Same principle applies to these Inverter ACs, Hisense Inverter AC compressors doesn't finetune their consumptions, LG Inverter AC Compressors does. So while LG Inverter AC Compressor is trying to save you some energy, it will compensate it by reducing the cooling, Chikina.

I went to kougar today to fix a bad video doorbell and saw this....
Jinko partners with Deye for ESS Products Extensions, They don't manufacture ESS Products at least not yet, they rebrand them.

I worked with Kougar during Covid19 to install Cisco Telepresence Systems around Abuja. Great guys.

My seniors I need your help

I did this setup last week, now we are about to add the second battery to it both Bluecarbon 15kw….


Please how do I parallel both? So I will get a single source out of them ?


Thanks a lot…
You can introduce a battery isolation MCCB or get a pair of jumper cables same size as the existing one then connect positive to positive and negative to negative of each batteries, then connect the positive of the inverter to the positive of one of the batteries and then negative to negative of the second battery.

The inverter was on last night but the Felicity controller was already at sleep even b4 the rain started, immediately the thunder struck the whole light went off and my inverter was just making a continuous beeping sound the display on the body went blank only the fan was working I switched it off and waited for sometime then put it back on same beeping sound with only fan work and display blank I didn't even know it also affected my Felicity controller only till this morning wen the controller didn't wake up
So sorry bro.
The strike probably happened to both AC and DC Circuits, That's why you should have both DC and AC SPDs tied to proper earthing, and Also ground your panels.

Is LG dual inverter different from LG smart inverter? I got the latter and it seems that the consumption only drops to around 850w after working for about 5 hours after the room temp has reached like 25 degrees. The setpoint on the remote is the lowest (16 degrees). The ramp up consumption when it starts is around 1015w

I also read in the manual that some model has "energy saving" mode, but it seems I can't find that option in this model of mine.

I hope I havent gotten the wrong model for use on solar set up.
You definitely did get the wrong model, Please get LG Dual Inverter GenCool B

LG Smart Inverter has about 50%-60% Energy Saving while LG Dual Inverter has 70% and LG Dual Inverter GenCool B has even more than 70% and can retain the Gen Mode memory after power loss. That's a function we upvoted to have over the years.

High or Low? Attached is a photo of the specifications. And I'm yet to connect the panels so can't tell if it will be series or parallel.
Definitely High Voltage. Your PV Breaker and Fuse should be rated 16A 500V DC and your PV Cable should be 4mm MAX

U didn't capture distance in ur calculations boss cos of voltage loss
You will loose more with more cross-section in relation to distance bro.

Do this when you have the time: Get a 12V Okada Battery, cut a 30 meters of 4mm PV cable, use it to power a 12V Okada bulb. Do same for a 10mm cable, same length, Use a lumen tester or use your eyes to test the brightness of the bulb, come back and tell us with which of the cables was the bult brighter.

That's what the installer I contacted said I need to run it. How bad is it? And how easy is it to get the one you are recommending? Someone also told me that because the panels are big that the cables have to be 10mm.
What capacity of panels are these?, How many are they? What type of Array (Series or Parallel)?

For the cable see attached, nothing abnormal, just that your PV Cables should confirm to the features you see on the picture.

The abuja setup

Still waiting for the second 15kw Bluecarbon


Seems they don’t want to product the ones with smart bms any longer?


My people is there anyway I can use solar assistance with the battery? The inverter actually comes with WiFi dongle! The inverter is SRNE 8kw
Please I need your capacity test result on the Blue Carbon 15KWh batteries. I would also suggest you don't run it for too long before attaching the second unit. Because of INTERNAL RESISITANCE wahala.

Yeah. I got SAKO instead. Yet to set up though. Just one more piece (10mm DC Solar cables).
10mm PV Cables for such a small unit? Honestly? Why do this?. You will loos energy bro.
The most practical wire for solar panels is PV1-F 750V-1000V Anti-Stretch Shielded Outdoor solar cable, this cable is most common in 4mm2 and 6mm2. A very rough rule of thumb is for arrays of less than 20A can use 4mm2, and 20A or larger should use 6mm2. If a larger size is required, it is recommended to run twice from the array to the solar controller.

No i meant, does it work for all Felicity inverters.

I have the 5kva IVPS5048 and was wondering if it will work with it.
Oh yes, The Module for Felicity works for all Felicity Inverters equipped with RS232 Port.
There is a 4G Model that works with RS485 Port also

Thanks, which inverter brand do you recommend for a budget of 350 to 400k?
Any Good 3KW 24V Voltronic Based Inverter within your budget will be ok. Felicity, SAKO, SNRE, MUST, Ipower, etc, If you can up your Budget a little, Go for Growatt.

Hello Chief.
I'm curious. If batteries have short shelf life, how do manufacturers and sellers store them in their stock before sale which may take months?
Usually they would factor in some months from Production to Shipping. This might take out 6 - 8 months shelf life for Flooded Batteries, 5-7 Months for Gel Batteries, 10-14 months for Lithium Batteries. So resellers have average Max of 6 Months or less to sell the battery.
This accounts to why they don't recommend you store them further than necessary.

dollarnaira:
Depends on type of batteries
Lithium generally has nothing to do with sulphation.
Please do not store your Lithium Batteries for too long without trickle charging them from at max 3 months interval.
They might gradually deplete beyond DOD and you might need to jump start them and there are also chances that some of the cell might not operate as normal as should be after that.
Lithium Cell Warrantee does not cover this scenario.

PLEASE TAKE THIS SERIOUSLY

Good evening, please I want to start buying materials and keeping them instead of waiting to do it all at once.

Which should I buy first? I was thinking of the growatt SPF ES5000, then panels and batteries.

Which type of panels should I get and battery type too.

Any other recommendations are welcome, especially ways or materials that will not cost me a lot but still be able to work

Thanks
Buy them in this order: Inverter>Battery>Panels.

Reason: Inverter has a long shelf life, Batteries has a short shelf life, Keep them too long, they would sulphate or discharge beyond DOD, Panels will be exposed to breakage and other risks when you stock them.

Secondly, you can start using your Inverter & Battery when you grab the batteries and add Panels later.

Third is that the price fluctuations affects Inverters and Batteries more than Panels.

I hope this helps

Dam5reey1:
Based on specifications, what you experienced is normal.. it can output 6500w maximum.

13A x 500V on each tracker. Is 6500w
That's 120A charging at 48V norminal which is the maximum it can charge.

But don't expect it to output 6500 on both trackers to give 13kw.. it will simply throttle them to 3250w each and output 6500w.

That's why it's written maximum full Load 250V per tracker. So if you have like 13kw. The trackers will work at 250V /13A + 250V/13A which is 6500w

Just like Epever allows you to use 2 tracker as 1, or allow them to operate as independent 2 tracker, output is still limited to maximum output.
Thanks for these additions, I hope people will understand better.

Yes the 15kwh is battery (DIY EVE LF304Ah or EVE MB31 314Ah cells).

They are the Hi-Mo 6.

Ok I'll work towards the additional 6 panels as recommended after I get the extra battery.

Thank you.
Ok, so let's take your total load to be 4KW, Plus 15KWh battery = 19KW
Your Panels Power take 6KWp.
On a sunny day, you need between 3-4 hours to fill your battery while powering your load at the same time. and once your battery is Full, the solar energy is far enough to power your load till sundown. See my Screenshot below

Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by jonescosmos(m): 12:23pm On May 05, 2024

Hmmm... Now I'm confused 🤔

If below is to be true that means the the 500v is the combined max voltage of the 2 MPPTs.

Meaning each MPPT is 250v/13A totalling 6500w for both.

Please clarify ify assumption is wrong.
No sir Voltage is constant because the 2 MPPTs are in parallel. Reason why their Amperages will rise (13A+13A) or (17A+17A) Max.

So each MPPT has a Max Voltage of 500V DC
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by jonescosmos(m): 12:20pm On May 05, 2024
Edrizz:
Maybe Deye is different then, cos I'm 100% aware that for SRNE, their 2 MPPT trackers are independent of the max input pv of 6500watt, 125v nominal voltage and 500v max pv n attached is my proof
The principle is them same, the picture you posted is for 8.8KW, 10KW and 12KW Inverters, And SENRE has done justice to what i said earlier about manufacturers not telling us about the power of individual MPPTs .

So it's safe to say that the 8.8KW has a max PV power of 11000W, the 10KW has 11000W PV Power and the 12KW has 13200W PV power respectively.

On the side of the Deye 5KW inverter it has a MAX Power of 6500W as clearly indicated on the Spec Sheet. So each MPPT is 3250W

Thank you for your response much appreciated.

I currently have 5x 570w Longi on the PV1 and 5x 625w Jinko on the PV2 which are both doing great.

Will add to more 2x 570w or 580w Longi and 2x 625w Jinko to the setup as I plan on adding a 15kwh to the already existing 5kwh.
@Bolded: are you referring to the battery?

Is your Longi Panel a Hi-Mo x5 or Hi-Mo x6?

Based on your pictures, your panels are obviously operating @ NOTC or less. So I recommend you add 3x570W Longi on PV1 and 3x625W jinko on PV2 respectively. this should get you around 6000W-6500W which is the Max your 5KW Inverter can do.

Edrizz:
The 2 MPPT trackers are 6500watt apart and the 370v (125 - 500v) is for individual MPPT tracker n not combined. So in total, ur 2 MPPT trackers can take 6,500watt x 2 = 13kw all together
The bolded claim is not correct sir. 6500w is the combination power of both MPPTs
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by jonescosmos(m): 11:20am On May 05, 2024
Ferdiwar:
Please I need your input on Deye inverter specs.

Mine is the 5kw with 2 MPPTs, the specs reads;

Max PV input power of 6500w.
PV input voltage 370vdc (125vdc - 500vdc).
PV input current 13Adc + 13Adc.

Now I understand that the input current is 13A for both MPPTs but I don't know if same is the case for the input voltage.

My question is "is the 370v (125v - 500v) for each of the MPPTs or a combined voltage for both MPPTs"?

I want to increase my panels wants to know if I can still add to already existing setup or make provision for an external CC.
Please note that your 6500W Max PV is the Combined MPPT PV Power, So each of you MPPT is Rated 3250W, manufacturer does not need to spell this out to you

370V is the nominal voltage for each MPPT, of course you can go all the way to 500v PV but don't exceed it by 1V.

Your best practice for your Inverter is for you to run 14x625w Jinko panels in a 7 series on each MPPT setup. Theoretically that should give you 8750w @ STC. But you will get something around NOTC spec of the panels
