[quote author=mcTrinity post=112952101]The bolded are so very untrue sir...

We need to learn to buttress some points here without outrightly condemning some methodology here; especially methods that have worked and IS still working.
It is true that using MC4 connector is a very fine and commendable method for joining external cables to panel own.

It is also true that cutting off the panel cable and joining by twisting can cause some or all of your points, buy that's not always the case. You made it sound general. After all, whether you want to believe it or not, people have used MC4 and ended up with more wahala of no-contact or using inferior connector, which also results to some or all your points too.

EVERYTHING depends on quality of material used and skill of the installer!!!

Over 7 years, I've installed so many hundreds of panels and I never, for once, use MC4 connector for any installation. And for 5 years plus, I've ALWAYS handled all connections myself untill I was sure my guys can do it satisfactorily to my standard. As a matter of fact, only one of my guys can do that and he's the only one that can do connection aside myself.

I did installation for one client.. 5 years later, while he was changing his batteries, he decided to add more panels. During the upgrade, the told me he noticed I cut the cables and that he would like me to use MC4 for the upgrade; that he's heard about the concerns you just pointed out. However, I asked him if his panel performance has dropped at any time, and he said no.
However, I took him to the old connections and I gradually removed all the double layer insulations on ALL joints and I asked him to see if there's any form of degradation. Bros, all joints were still much intact. The insulation tape didn't degrade. The cables were still looking good; none was looking dark or corroded.
That's how the man allowed me to do my thing.

Now, I'm going to explain how exactly I do my connections using pictures. Pictures attached were taken 2 years ago, which I use for classroom explanations during my Training sessions. Follow the pictures according to the numbers.

The only thing I want to add is this; most twisted connections have issues because most installers lack the skill and patience of proper cable joining. I've giving opportunity to some electricians and their twisting and insulating mannerism is just very local and road-side.

Referring to the pictures, after twisting together the strands in Pic 4, I first use an "A Grade" flame retardant white insulation tape for the first taping (pic 5) I buy this tape at N750 at ShopRite. Then I use an original Scotch tape to do the 2nd and final taping (pic 6). See pic 8 for the tapes

You can't use all this N50 insulation tape and won't expect it to untape (or unwind) as times go on. And during taping, ensure you tension the tape.

For the exposure, I always ensure I tie cables to the rail, and I ensure all joint sides are directly covered by the panels. Sun or rain, none would near it.

So, guy, there's absolutely nothing wrong with cutting off and joining. As long as you use the proper and professional method or joining. Even the National Electrical Code (NEC) and British Standard Code still have joining methods with different methodology like T-method, Married method etc... People should learn how to properly remove insulation, divide strands, and join cables. Then also, properly insulate them.
And while insulating, give like 1inch gap down before you start insulating and work your way upwards,applying tension and leaving no single air-gap.

Each year I go for maintenance (panel washing ) for clients, I inspect everything.... And always, all is intact and still performing optimally.

Finally, one thing with cutting off the head would help you with is identifying if the panel you bought comes with copper (whether pure copper or tinned copper) or aluminium.
Some years back, one man asked me to help check his set-up installed by somebody. The panels were just over 2years but no protection again. Like, the MPPT was not charging again and he was wondering whether the MPPT was bad. After troubleshooting, I told him that nothing is wrong with the MPPT and the problem could be that something is wrong somewhere with the Array.
Right on the roof, I started disconnecting the panels to test them one after the other. And yes, MC4 was used. First 2 panels were okay but the 3rd one in the string wasn't reading any voltage. Out of 9panels, 6 were not reading.

We now brought down all the panels. I decided to open the black boxes and test directly, bypassing the cables. Mehn, see decay! Cable has decayed at the point it's connected to the diode assembly and has literally decayed off. The cables were ALUMINIUM cables!!!

In summary, we changed all cables and soldered copper cables to the diode assembly. That solves it. However, the man later changed all the panels...

I've also had one client that bought Joysolar panels sometime and asked me to come and install. After cutting the first head and realising the cable was aluminium, we jejely changed all cables on all 12panels. And the annoying part is that, the aluminium is ALWAYS coated with copper colour. Not until you handle it, and then you'll realise it's aluminium.... That's is, if you can actually be able to differentiate

However, when you buy original panels from original source, you won't have doubt as to whether they came with Copper or Aluminium. They always come with copper (pure or tinned).

Whichever case, I love cutting and twist-joining... Trust me, some twist-joining outlasts some MC4 connections...

Whatever anyone finds comfortable, the key thing is the professionalism you applied in whatever method .. Cheers

* Thank you for this.

Good afternoon house. Pls who go help me with scrap charge controller like the one attached. I want to use the cover and sitting. Please help a broda out

@en0uwem I thought this matter is rested with @earthrealm recommendation.
1. Get another installer on ground to review ur present installation.
2. Don't be in a hurry to spend except 1 is done.
3. I saw d pic of ur installation and u said u hv change the CC to Felicity. As for me, it is the inverter you would have changed to hybrid with high voc. Growatts etc and have ur rest. Don't be taken for a joy ride.

Hello house, trust we are all doing great.

Does anyone here know the max charging current of the 5KVA, 48V ipowerplus inverter while charging from the mains ?

Also, does it have a dedicated lithium profile ?
I want to use it with a Pylontech UP5000 battery, is there anything I should be worried about ?

Cc : adrusa, niyiomoiyunade and other esteemed members

ojeysky:
2 and 3 are better but for remote monitoring features i will suggest you do growatt

Thank you very much

My good people, long time. Please between this 3 hybrid inverters which one to go for, functionality and rugged wise?

200amp × 4 = 24v
Inverter hybrid mercury 24v, 2kva

Pls how should connect the above
Pls pls pls.

1. What is your CC Max volt?
2. As your CC is PWM most CC in this cat volt 50v, better MPPT
3. The hybrid inverter did not come with CC? if yes then it is not hybrid

You need to retouch the soup to make it sweet

for d battery 4pcs, 200amps to 24v 400amp. first series 2pcs then do same to other 2 pcs to have 2 sets. then parallel +pos of set 1 to + of set 2 do same to -neg then take ur inverter 24v +pos and -neg. inugo

Good morning great farmers. We have about 360 layer birds in our farm already laying (for d past 5month). We maintain their deworming, Lasota and multivitamin cycles. We get 9, 10 and 10+ crates in a day. Though we still noticed up to 4-5 soft eggs. On their recent Lasota cycle, we gave them 1000 dose, followed by our usual multivitamin (egg formula). we notice egg drop now 4, 4+ crates. their poo is okay and environment okay. Pls will their laying go back to what they use to lay due to d lasota overdose? is their anything I need to give them? Nagode

Thank you guys for your valuable inputs. Current production 7crates+ today. Currently on drug break, placed on normal water 2day running. Though we still get some small eggs/premature lays. it is getting better day by day. Thanks

Good day guys. I just got a new car battery from a friend who sold his car as a scrap.

The battery is still new so I think I can be using it for my solar system (I know car batteries are not good for solar) but I can’t let the battery just get wasted like that.


Can anyone suggest a necessary recommendations I need to take so I can enjoy the battery to an extent.

Chaiii and I need this battery for the replacement of my car battery. Please make una help a broda out o biko
