I just checked it now and it seems to be quite okay. One thing I also noticed now is that as soon as NEPA took the light, the inverter switched off and took about 2mins before it came back on. And at some point, it stopped charging via grid too, I just noticed that. Meanwhile my battery is still above 80 percent

Check your battery DC breaker, most likely that there’s a partial connection From battery to the inverter.

A new solar system was installed for me. It was 4 panels of 590 watts each, Africell. Then a 220 Ah tubular battery, then a 2000 watts D&G hybrid inverter. It has been working perfectly well. Four ceiling fans, a plat screen tv, a 270 watts freezer, about 20 power saver light points, a blender and few other things al working at the same time during the day.
My question, as a newbie, is: can I use my 1000 watts electric cooker on it during the shining hours of the day? Assuming I put off all other loads?
Thanks

No, it’s not advisable.

Greetings to everyone, let’s try to engage more in educative discussion that can broaden our knowledge in the field of solar energy technology.


In this light, can we share our views on this:
Which is more better and recommended? Whether to Connect SPDs to Breakers’ INPUT or OUTPUT.

Bruteality1:
Can you please recommend a very good infrared cooker?

Go for this and thank me later.

Dispute with KunlexyInc1!!

I'm bringing to the house an issue which honestly shouldn't even exist.

I got a phone from afforementioned seller and the phone was picked up from his office by dispatch service. Item was dropped off at the lagos airport and send down. When I received the device here, the phone was at 2% and I was scrolling through the phone when it went off(or so I thought). I plugged it in to charge and felt it responding to that but the screen still blank. I tried pushing the bottons and could still feel the phone respond both audio and haptics to them.
I immediately contacted KunlexyInc1 and told him of the issue. He told me to perform a force reboot which I did but to no avail.
Now, the issue has now come down to refusal to refund as he has refused my request for a full refund insisting I part with some money. He has also refused my consideration of a replacement device contingent on warranty of some sort on the replacement device(which I asked for simply because he was adamant at the start against baring responsibility).
I have tried my best to make him understand this is not in anyway a fault of the buyer nor even logistics for that matter because I received phone intact without any dings or indications of fall damage, neither did he when I sent it back to him for checkup.
I'll very much need your contributions and to advise him on this matter.

I will suggest that the Seller refund 300k out of the 310k and let the Buyer accept it and move on because the circumstances surrounding the phone’s faulty status isn’t clear to us here.

AdenimerXYZ:
If he posts an item now and you call him in (say) about 10 minutes after. He will say it's sold.
Na ghost dey buy am?
I no believe all these deals abeg. It reeks of audio.

I doubt it, his prices are always good and those that need the items won’t hesitate to book them immediately. His previous buyers have also attested to their experiences with him on this forum so it’s not a case of ‘audio’ deals.

Sapiosexuality:
The inverter is 3.5KW and I use four panels of 555W each.

Ok, this is not bad depending on the minimum PV input specifications of your inverter. However if this fault didn’t occur from the beginning of your installation then it could be as a result of poor wiring or connections from your panels to the DC SPD. You may need to retighten all PV wire connections and screws on the DC SPD and breaker because partial connections can trigger such faults. Meanwhile, your DC breaker seems to be broken and the culprit partial connections can even be from this breaker, so check it properly and if necessary replace it with the appropriate DC breaker size.

Nice work, well done.

Sapiosexuality:
I think it usually begins towards the evening period. In the morning, it is fine but once I return from work, around 3-4, I notice the blink again.

On Tuesday, I switched off the inverter, surge protectors and supply and put it back on, and it didn't happen again. But yesterday I did same but it didn't work until I switched off the SPDs and it ran smoothly and then I switched it back on two hours later.

I think it has to do with very low PV input from your solar panels that’s causing the error on the inverter. Maybe your solar panels are inadequate if not by 3-4pm, there will still be sunlight and the PV from the panels should be able to keep the inverter operating properly. What’s your inverter capacity and how many solar panels and their wattages.

Sapiosexuality:
Guys, I need your help.

For the past two days I've come back home to my Sako Solar Inverter beeping, not charging and displaying Error 51 which is an Overcharge or Surge Error.

In fact, yesterday, I had to change the SPDs just to avoid any further complications. I noticed that once I put the SPDs off, and it running on the batteries it doesn't happen.

What exactly is happening? The weather has been poor but it can't be the weather or external forces? What should I do? Does the inverter need repairs or just some code issue? Thank you.

From your fault description above, the bold line is not quite clear to me can you share the pic of the said SPDs for better clarity.

temizeee:
Coming from someone that own and used infared and induction cooker, I will pick an induction cooker anyday anytime over an infared cooker. What i like most about induction cooker is the speed at which it cooks, It saves more energy than infared cooker…i got few set of stainless pot at a local store here that works with induction cooker at a ridiculous cheap price…4 sets for about 20k.

I will always prefer and recommend a good infrared cooker to induction cooker for good reasons. Meanwhile, can you share the pic of your own infrared cooker.

jFrankNorfleet:
I don't think I'd ever need more than 6kv inverter as the shop has limited space and cannot take any more games although I'd be interested to know what other benefits a higher kV inverter would do for me asides adding more loads

I do see suggestions about adding more panels and batteries

Ok if you’re not planning to add more gadgets or expand your business, then 6kva inverter is ok but you will need a higher capacity battery like 15/16kwh for longer backup time and that will require more solar panels for charging.

jFrankNorfleet:
I'd run installation for my gamehouse within the next 2-3 weeks

Pls house I need you to tell me what's wrong with this quote given by my prospective installer. Focus less on the price and more on if the setup will be okay for the gamehouse and how to prevent issues with the setup


These are what the gamehouse would comprise


Lg LCD 32 inches TV 140w *2
Samsung 32 inches led 56 watts *3
Samsung 32 inches lcd TV 110 watts *2
Samsung 15 inches lcd TV 40 Watts *3
PS2 fat 80w 3pcs
PS3 super slim -85Watts 2 pcs
PS3 slim-85 watts 5pcs
PS4 slim 100w 2pcs
Ps5 1 pc 200w
Yokaho DC ceiling fan 40w 1pc
1 duravolt 18 inch standing fan 27w 1pc

Note: I'm yet to get ps5 but it's in the pipeline. Also only 7 out of the combination of 10 PS3, ps4 and ps5 can be operational at once due to limited number of 32 inch TVs




This is what he quoted for me for the above setup

Is there something that should be tweaked for more efficiency?

For future growth and expansion in your business, I will suggest you try to go for a 15kwh/16kwh LiFepo4 battery, an 8kva hybrid inverter and increase your solar panels to either 615wx12 or 650wx10.

twinskenny:
Thank you chief for your observation


This is just inverter and battery installations only.. I don't use busbar for two batteries installations I just paralled them with the same cable length.. all good... I have installed both AC in and AC out breakers installed . thank you for your observation..

I can understand you now boss but it’s still better to install an AC SPD and Voltage Regulator to safeguard the setup.

twinskenny:
Done over the weekend!

Location ikoyi

10kva srne inverter

32kwh deriy lithium battery

Well done, but I can’t see any SPD in this your installation and you didn’t use bus bar box to combine the two high capacity batteries. No heat aerosol or fireball extinguisher installed. By the way, it’s just my personal observations.

Gshems:
No one will. My gas is resting. Only used when we want to cook multiple foods like rice and plantain in the morning . The induction cooker go cook the rice, gas go fry plantain

Next time you can go for double infrared cooker if you have high battery capacity. Something like this

OgogoroFreak:
it consumes more wattage than what it shows sometimes too.

That is, it may consume more or less wattage than what's indicated.

I bought pinnacle brand. My friend bought mama home brand and both work same way when it comes to wattage consumption when I tested them on a wattmeter.

It's normal for electrical devices to consume less wattage than rated not when they consume more wattage than rated too.

My blender rated 1500w, hardly consume more than 900w

Ok but I have never experienced that while using mine which is close to a year now. Normally, the appliance should consume lesser wattage because the rated is usually the startup surge power. But if the appliance is now consuming more wattage than the rated power while running/operating, then it’s not a genuine product.

OgogoroFreak:
Not fake. What u said is part of why I said the wattage displayed on its screen is for decoration.

Sometimes, you set it at 2200w and it's consuming 1500w or any other wattage it chooses.

1000w should be 1000w. 800w should be 800w.
I mean, why put a screen that displays wattage if it's not going to consume that?

I don’t think that should give you much concern since it doesn’t affect its function and it consumes lesser wattage than what’s indicated. My 4Ltr Qassa electric kettle rated at 2000W actually consumes 1900w while working.

twinskenny:
Abeg so the induction cooker has is own pot again? The normal pot at home won't work?

Yes, induction cookers only work with pots that have magnetic base. Pots made with pure aluminum or steel won’t work on induction cookers. On the other hand, infrared cookers work with all kind of pots including clay pots and cooks evenly too.

OgogoroFreak:
The problem I have with this infrared cooker is that the wattage you see on the display is for decoration.
200w would be consuming 600w - 1200w
800w would be consuming upto 2000w

I used a wattmeter to see the actual consumption.

But my induction cooker was accurate

That must be a fake infrared cooker, in fact when I set my own at 1000w it will be consuming from below 800w on the inverter.

Yes, and it’s quite fast and the power consumption - wattage can be regulated.

chadbasin:
This really works with any type of pot?

osayuwamwen:
good evening all, I need help I'm having trouble with my maxi induction cooker, the induction cooker keep going off on it own while the red power light remain on, I notice that d fan does not come on and when the cooker reaches certain temperature it will just stop working while the power light is still on

It’s either the cooling fan is bad or the thermostat is malfunctioning. First check the label on the fan to see the voltage specs whether 12v dc or 220v ac so that you can test the fan with external power source and then change it if it’s bad. Without the cooling fan running when in operation, the thermostat will overheat and cut off power from the heating element.

aloyt:
Pls I need expert advise on the type of solar panels i can use for this inverter with the spec below. It's an SRNE HF-2430S80-H but my concern is that the Max PV input Current is 13A and I intend to get at least 4qty of 615W Jinko panels (to be in series) but the Max. input current for those panels exceed that of the inverter rating. I want to know and get an expert advice if this will be an issue for the inverter or if I need to go lower to say 590W panels which has about 13.36A input current.
I need advice from people here who may have the knowledge on this. And to know also if the max current for the solar panel rated is ever attained in real life. I want to be sure it's safe to use these panels with these ratings with my SRNE inverter with these specs.
I'll appreciate response from OGs here. Thanks

I will advise you go for the 570W and increase it to 5 instead of 4 since it will cost less than the 615w. It’s important to keep to the inverter manufacturer’s specifications so as to avoid shooting yourself in the foot.

Bryanluke:
bases on my knowledge i taught the normal electric cooker is 1500w but with this 1200w on prepaid meter with BAND A 4.4unit.. hope it won't consume less than 1 unit if I want to cook beans with it

If you set the infrared cooker at 1500w which will be 1.2kw on the inverter/meter, you can cook 4 or 5 cups of beans within 45minutes and it will be very soft. So your energy consumption won’t be upto 1unit for the 45 minutes cooking.

oloet:
Close to a year

Alright then, try add more panels because 100v PV input is just low for a 500v Vmax system. You are using it to charge the battery and also power your loads at the same time, it will eventually shorten your inverter lifespan.

Bryanluke:
wait does it not consume much when used with prepaid meter, I mean the infrared induction cooker unlike the normal electric cooker that chop light

The infrared cooker doesn’t consume high electricity like the regular hot plates and you can regulate the power/wattage. You can cook beans and other foods with 1200w setting on it which will be around 1000w on the inverter or pre-paid meter. One can even cook and warm foods with 800w/600w setting. Mine comes with a grilling steel for barbecue and other roasting.

oloet:
Nothing is going to happen to the mppt because no parameter was exceeded... the panels are original. It is jinko 590w monofacial.

Ok brother, how long have you been using the hybrid inverter.

Gshems:
How much be gas per kg now?

25k should be able to get you 10Kg cooking gas. We, team infrared/induction cookers have escaped that gas ‘palava’.

oloet:
You might be right but I disagree, my hybrid is 500v voc but I have 2units of 590w jinko (100v) and I get good yield from them and as much as 1.05kwp in peak sunlight

This is because your inverter is pulling everything it could get from your two panels just to charge your battery and
your location is a contributing factor to the high yield. If you continue to stress your hybrid inverter to charge your battery with those two panels this way, the inbuilt MPPT won’t last long. I also doubt if your panels are actually 590W since they are both generating 100v because even 650w has actual VoC.of about 50v.

Dabss:
please let us know if adding more panels improves your yeild. Alot of use are having similar issues. 🙏

No doubt, there will be a great improvement in the energy yield. It’s what i know and understand about hybrid inverters. For you to harvest a good energy yield, your PV must be at least 50% of the Max PV. Once the PV input is adequate enough, your loads will determine how the inverter will pull more energy from the panels with respect to the intensity of the sunlight.

Bruteality1:
You're on point. The highest is 162v. Are you saying if I get 2 more panels I'll get maximum PV yield from the panels? What if I add 3 more 615w panels

Yes, I said your panels should be at least 6, so if you can make it 7 or more the better so long as the total PV does not exceed 450V. Hybrid inverters rely mainly on panel voltage(dc) to generate AC power (Wattage) and normally convert the excess voltage to current.

Bruteality1:
My current generation on 4x550w is 1.3kw max and it's honestly not enough cos I don't do use some things I would like to do in the afternoon like AC, ps5 etc. I prefer the battery to be filled up first before using those things. I would be able to use 3kw comfortably.

Here is the inverter specs

You will have to increase your panels to at least 6 for you to get better energy yield from your panels because from the specifications on your inverter, your PV should be at least 240v and I’m sure that your current 4 535W panels can’t produce that. Highest you can get is 40v x 4 = 160v. This is the reason for your poor solar energy harvest.
