It is simple really. The ratings on the s were measured under certain conditions which are listed. If those conditions are EXCEEDED, the measured wattage will go up and exceed the label ratings. It is science. I had also briefly seen my yield exceeding the label. And my s are even 2nd tier Flame solar s.

However, it is also important to recognize that many charge controllers tend to show higher yield than the actual yield. I don't know whether this is a limitation of the measuring equipment or deliberate fraud.

These are 2 different days..

The s are 5, units of 570w which make its total of 2850w, but in the picture you can see this is what is going into batteries 2716w, there was about 150w load inverter has idle consumption too.

The inverter do show 3000w+, even If inverter dey lie, this Shunt has more precision considering there was load on and battery are being charged at 2654-2716w say a lot about the output over 100%

Haven't had power for more than a week now due to transmission line wahala in northern Nigeria. Even when I did, it was 2 hours light day time as Na Band D nepa put us.
Is getting the mtn lumos advisible or should I get normal solar and inverter?
I need to power laptop, phones, rechargeable fan and 40inch TV.
My budget is 400-500k

Never try that MTN shiii the money you have can get you a decent 12v system much higher that the lumps.

Recently s are doing over the rated output, noticed this first from smilinsun solar comparing 2 s on his youtube channel and they both did convincingly over 100%, individuals has reported same here. Even my mixed s reported over 100% instantaneous output last week.
I think the cool weather and clear(less cloudy) blue sky are big contributory factors.

This is why we say buy top tier s.

On a good day when the stars align you will smile

What solar setup would you guys recommend for a frozen food business on a budget?

Aim is to use 2 freezers.

Do you have any efficient freezer you can recommend too?

Check for any inverter freezer with low wattage.. check specs on the freezer before buying. Scanfrost inverter freezers are pretty energy efficient. I'll attach the spec sheet of a 215L non inverter Scanfrost freezer as an example.


You can start with the following:


1) 3kva inverter (preferably transformer based inverter)
2) 5kwh of battery
3) 6 nos of 400w Solar s for a start. You can increase this as business grows.

The freezer (attached below) at highest consumption takes 160w, that implies if it runs for 12 hours daily it'll consume 160w X 12hours = 1.92kwh. So 2nos of it is 3.84kwh. You don't really need to run it up to 12 hours as it'll be frozen long before this.

Let the ogas at the top provide cost of above. Cheers.

Freezers don't need anywhere near as much as power as you'd think.

The answer to this will depend on how many hours you need the freezer to be running AT NIGHT. Energy storage (batteries) is what s for most of the budget in a setup, I'd say.

If you can make do with the freezers running from 8-5 during the day, and then for maybe four hours in the middle of the night, you'll be able to get a setup that isn't really that expensive. Maybe around 800k.

Are you in need of a Rugged Industrial Automatic Voltage Regulator (AVR) & VERTIV UPS . We have all sizes of AVR & UPS in stock and we have well Trained Engineers for Maintenance. We are located in Abuja and Lagos. You can Call/Watsapp us on 08066332919

800k for what sir? Inverter and battery alone wud need more not to now talk of s and accessories with installation fee

Based on what?

Inverter ACs vs Regular ACs?

Are the inverter ACs energy efficient enough to justify their extra cost over regular ACs, which are also getting fairly energy efficient on their own?

What are your thoughts folks?

On 23/10/24, for 22 hours and 15 minutes, the total energy consumption was 11.36 kWh. That's an average of 0.51 kWh per hour—pretty impressive for a 1 HP AC. Someone should do the same for a non-inverter AC; let's compare.

So far, I have no regrets about paying extra to get an inverter AC. The AC make is LG, and it is a Dual Inverter model.

FYI: Figures may change due to a variety of factors, such as the temperature of the location, room size, room insulation, how many times doors are opened and closed, the number of people in the room, the temperature set on the remote for the AC, and the AC mode in use, etc.

CLEARANCE SALES:

36 units of fairly used 350w Felicity solar s in good condition available at 50k each.

Good inverter ACs (not Hisense), yes.

Thanks so much for your input, mate.
I will want it to run for at least 12hrs.
As I will need things to freeze well, I think 12hrs will just be okay for that.

I feel better hearing it shouldn't cost much though.

This breakdown will help a lot.

Could you please recommend an inverter to use for this?

I had a guy recommend hybrid Felicity inverter offline, do you think this is a good option?
So sorry for the too many questions already.

Felicity not bad. Transformerless hybrids are cheaper but often, in general , not as rugged as transformer based inverter in handling surges. Felicity IVPS/IVPM series are transformer based. The Felicity IVPM has hybrid series. The Felicity IVEM hybrid models are transformerless and of course cheaper. So you can check out Felicity's IVPM hybrid series.

Based on personal experience, I'll say yes, inverter ACs are worth the extra bucks.

I have 3 inverter ACs (2x TCL 1HP and 1x Haier Thermocool 1HP) which are always on the lowest inverter model and consumes max 1.2kw/h.

When not on inverter mode the figure is over 2.4kw/h.

Felicity is ok
SRNE and Glowatt are also solid brands you should consider.

Good day, installer requested 10mm DC cable wire. Some one I have been chatting with here before now recommend 4mm or 6mm but this installer says I should get 10mm. Help me check this pls, I have 4.2kva welion Inverter & 3 of 475w
Distance of 20yards for s to DB
1 DC cable 10mm ×10yards=#7,800×10=#78,000
2 AC cable (2) coil =2.5mm cole-mester wire=#49,000×2=#98,000
3 Bolt and nuts 🔩 =10 pieces =#3000
4 Change over. 100A =#7,000
5 Trunking pipe and concrete nail =#3000
6 Cable locks=#1,500
7 Breaker =#13,000
8 Surge protector DC =#22,000
9 Breakers box /9 ways.=4,500

If you can afford the inverter freezers great go for them.

You can go for any of these;

1. LG (confirm if fouani has the normal type in stock as they only had the tall standing ones the last time I checked.
2. Haier Thermocool (check around for their authorized dealers)
3. TCL or Aeon (check jamara homes website).

If you can't afford the inverter models at this time, buy the normal/non inverter ones and reduce the thermostat from 7/8 to 5 this way you won't need to manually turn them off all the time and with a small battery bank you are sure of constant power to the freezees and enough battery juice to start your day with.

I prefer a higher wattage Solar as it reduces the need for bigger roof space and hybrid inverters with high voltage PV.

The argument between top tier solar s and the lower tier ones is not settled. Some people are of the opinion that what you get per naira is what is most important. If a 300W low tier gives me only 70% yield, but costs me only 50% of what I will pay for a top tier 300W , isn't the maths already leveling up?

12 hours.

Two jinko 555w s - 250k
Find a small 12v hybrid inverter to buy from brands like Sako, Welion, CWorth - 250k
Powmr 100aH battery -290k
Accessories and installation - 150k

Put the inverter in power saving mode so it doesn't invert if it doesn't detect a load, then buy a timer for the freezers.

You can run on solar from 8 am - 5 pm, which is 9 hours.

Set the timer to come on at midnight and go off by 3 am.

My ~200L chest freezer draws just 110w. Even a 300L freezer shouldn't take more than 150W. Two of them 300w. Three hours of use should have the battery down to about 25% of charge.

Twelve hours of runtime daily, and your freezers remains frozen for 24 hours.

The problem is the starting surge. A freezer completely filled retains more than sparsely filled. He may like not need mid nite due to starting surge. A good freezer should hold up after 7hrs of freezing till the next day. Most of us underestimate the power of good Satchet inverters. So most importantly, a good freezer is the main thing. 200L at 110w is bae. The thing is morden 200L is less in capacity with the ones in the past.

True. For example, my freezer surges to 850w for a few seconds before dropping.
Easy solution to starting surge is to use two different outlets and timers and just set them about ten minutes apart.

There is a solution to that called a soft starter. Very small circuit. I've even seen a DIY of it. The guy used on on a sachet inverter to run a grinder.
