Ok im in porthacourt, i called a technician to check it, he said the problem is from the driver card, which is not readily available now.

Its the 20mbps unlimited plan. Ive used 1tb so far this month and the data has throttled yesterday

HeavenlyBang:
I did, it just draws from battery and panel output doesn't rise.

It's bizzare, since after about an hour everything suddenly went back to normal.

Edrizz:
My brother, add an additional 580watt panel to ur existing array n everything will hence go smoothly. I'm also using that brand n type of ur inverter and I have 5pieces of 400watt on it n on a good sunny day I use the system to power my 2kw electric kettle n sometimes inductive hotplate self, those two appliances draw 1,300+ from my panel n then draws additional 900+watt from my 5.888kwh lfp pack cos my freezer is always in use with any of the said appliances...but in a hot afternoon when I use my 1000watt philip iron + freezer, my battery will keep charging at around 100w+ while I consume 1.2kw+ from my panel for the said load... all in all, my 2kw panel have never gone above 1.365kw in this rainy season, though I'm yet to experience dry season harvest sha

HeavenlyBang:
I plan to.

Fwiw, outside of the times when it does these shenanigans, I get about 1100w from the panels. I'll add another 580w panel, though.

brightk:
what is ur array size?

Trippledots:
Hope you read user reviews about the unit o. BTW, some NL here sell similar units, make we de encourage our guys here too.

The inverter display looks nice sha. 😊

Share the product link if you don't mind

osayuwamwen:
Yes sure, the inverter got delivered to me today so far it look nice very quiet when working, the fan is temperature control it only comes ON on heavy load and still doesn't make much noise compared to my previous inverter and it is way more power efficient the inverter they make me feel like my 220ah battery don double to 440ah, the watt display on the screen is not too accurate.

As for sellers here the issue is that they don't add prices along with what they are selling, I don talk am B4 put yr price along with what u are selling so that potential buyers can easily see if it is within their budget, not every serious buyers get time to call or message for price, AliExpress, jumia and jiji are all market place with different sellers prices are place along with every product u don't need to message a seller privately to get price of wat u want to buy.

This looks like an off-grid unit. I run an off-grid unit as well ( about 2 yrs and running) and I haven't had any thunderstorm issues. Someone earlier stated that if your system is purely off-grid, you MAY have some immunity from lightening strikes.

My rig is not earthed, and my house earthing seems compromised, but so far so good.

I have a knife switch that I physically use to change to grid if I need to.

osayuwamwen:
I don't understand what you mean by off grid unit ,
my former inverter that was killed by lightning was not an hybrid inverter but it can be charged by grid power and my house is connected to grid power

I see a lot of people discuss their challenges with lightning induced electrical surges. Let me start by saying I am in no way an expert on this subject. You still need to reach out to experts and read on your own so this should not be considered a professional advise more a how "I" did it.

Another thing to get out of the way is. no amount of protection help you in case of a direct lightning attack.. No amount of SPD or surge protectors. A direct lightning takes almost everything. Fortunately direct lightning are very rare events, what we see mostly are caused by indirect lightning or near by lightning which is what and SPD and lightning protection system can help with.

What are surges. Surges in a system can occur from the grid (NEPA) and most electrical surges comes from the grid.. usually caused by heavy machinery used in a near by house or factory or heavy equipment like fridge and freezers. They introduce spike into your circuit.

Surges can also be caused by induced or sudden increase or spike in voltage / current caused by a near by lightning stike. Such a spike which is called a surge can be very high.. as high as 50kvA to 80kvA. This sudden spike occurs very quickly.. sometimes less than a second.. hence they are usually caused transient electrical surges.. they happen within seconds and dissipate. But they can do damages to electrical equipment within the time they occur.

Like all electricity, Surges are looking for ground and the best way to protect your equipment is to provide a pathway to ground. Ground here means your mean house earthing. This is why earthing is very very important and it is the bedrock which lightning protection should be based.

Check my last couple of posts on earthing and best practice I followed and how you can check your earth resistance to confirm that it is within spec

How can indirect lightning ingress into your house.

Mainly through external fixtures which are linked to your electrical circuit. It could be a satellite dish, or a solar panel, or a cable from the grid. (Nepa connection) all of the listed are can pick up surges induced by near by lightning and bring them into your home.

Protection in layers

There is no one red button that will protect your house from lightning. the best approach to guaranty you survive a lightning surge is to take protection in layers.

SPD or surge protection device helps to protection against all electrical surge by drawing the surge to itself and sending it to ground (your earth rod) and away from your sensitive equipment.

SPD are rated in Type. Type 1,2 and 3

Type 1 SPD Type 1 are usually installed at the entry point to your house. like by the NEPA connection ingress to your house. or by your PV combiner box before it goes into your inverter / charge controller. They are the most powerful and are designed with withstand very large surges.. between 50kVA to 100kVA. The take this large surge and clamp it down to a lower surge like 2.5kva, sending the rest to ground.

of cause 2.5kva is still too much for most of your equipment.. this is where a Type 2 comes in.

Type 2 surge protector are not as powerful as a type 1 and they can handle surges between 40k to 10kva and clamp it down to like 1.1 to 800va .. much safer.. ideally in a well coordinated setup. Type 2 pick up from type 1 or type 1 hands over to type 1 to further clamp down the surge to a safer level. Type 2 are usually installed in your main house distribution box often time paired with the main house breaker.

It should be known that a surge protector should always be paired with an appropriately sized circuit breaker. The surge circuit breaker and earthing work hand in hand. When there is a powerful surge, the SPD trips the breaker and sends the surge to ground.


Type 3 are like your normal APC surge protector power outlets you see in electrical shops and super markets. They handle smaller surges and break it down further for your device.

Things to watch out for when getting a surge protector

- (Ue)The rated voltage. This is the amount of voltage that is allowed to pass through the surge protector. Anything high than that will be shunted down to earth. You want to appropriately size your surge protector so that the rated voltage is just above the rated voltage of the protected circuit. e.g for AC circuit, a 350v or 300v surge protector is ideal if you get an 800v surge protector.. you are letting in way too much surge into your equipment. Remember spd acts like a capacitor, they help protect your equipment from voltage spikes.

This spikes happen all the time and often time equipment are designed to handle them but each spike as stress you want to protect your equipment from.

( Imax)Maximum discharge current. This is the maximum amount of current an SPD can protect it can be 40kA or high or lesser depending on the class / type

Max protection level (Up) This is the voltage surge protector would clamp down the surge to. It can be 1.4kV or 1.5kv

All the above specs are important in setting up your surge protection device.

There is so much to say and write about surge protection. Again not a professional and not qualified to give advise on this. But hope this guide people on how to think around surge protection.

cheers

I agree with you on this, it is what am trying to explain to them, but in my case I think the lightning came through the panel it killed my inverter and controller what surprises me was that my Felicity controller has already gone to sleep, it was not even on but it still got hit by the lightning, though they were still able to fix the controller, na only the inverter require change of board

FEGEITOK:
Did you earth your panels?

Just asking because during my initial install the installer didn't.

I did it myself after the fact.

When I asked, he said it wasn't necessary.

But I knew better and had to sort it out myself.

If you haven't, please do.

Kingju:
How do you earth it please

GloriousGbola:
Do you also have a seperate lightning arrester? Because lightning should hit the arrester first

FEGEITOK:
Currently? No.

Will address this ASAP.

I received my 3 units of Felicity 25KW yesterday, I intend to replace my 4 Units of Felicity 15KW and use them to redeploy my redundant 16KW Deye Inverter.

I noticed some differences between these units I got and the 25KW sold in Alaba and I contacted Felicity Engineers in China straight off.

They have revealed some important points about both models. They also sent the UN38.3 of one of the Pack, waiting for the second one.

I will not post our conversation here in order not to cast their updates in Alaba and drive them to start changing stickers and writeups to circumvent the system and sell to you.

TO ALL FELICITY LITHIUM BATTERY 25KW, 15KW, and 12KW PROS{ECTIVE BUYERS in 2024 AND FUTURE, FEEL FREE TO REACH OUT FOR THIS IMPORTANT GIST BEFORE YOU BUY.

hello everyone, trying to make a decision between SRNE and felecity inverters.. for those who use SRNE inverters how would you rate it... are there service centers around lagos and does the company stand by its warranty claims
