I don't know about bonding neutral to earth. I will need to clarify what the electrical contractors did
brightk:


IMHO, if u had a main db in that house and bonded ur neutral to earth.. i think only that breaker controlling the fridge will trip. and that shock wont be there. U touchin the fridge seems to complete the circuit for flow of current.

. There is more to this earthing stuff than wat the eye can see.... EXperts in the house,, does anyone have experience bonding neutral and earthing on ur main db panel?

Found a naked wire (mice or man attack?) This seems to have resolved the issue and all seems to have returned to normal for now

FEGEITOK:


Maybe you have a case of degraded wiring.

Or you have a case of water ingress into the wiring.

It seems you don't have an RCCB.

Cause when I had such, and had a case of water ingress whenever the freezer was on, it will turn off the electricity for the whole house.

I knew that there problem was the freezer because if the freezer was off, no tripping. Once I dried the water everything went back to being ok.

Bring out the circuit board of the freezer if possible or alternatively use an external light source and bend down to inspect.

Another thing, are you sure rats or mice didn't compromise the wiring when you traveled?

Will talk to my electrician on the earthing and breaker observation.
Thanks++
jonescosmos:
You should change the compressor ASAP (use the opportunity to change the it to r410a (good choice) or r600a (better choice) gas compressor, these are energy saver refrigerants energy saver or inverter fridges and freezers).

Reconfirm that your EARTH is still working (Might be responsible for the high consumption from the freezer because of current leaking to earth)

If your earth still works which I suspect is not, the breaker powering that freezer should break due to the surge.

Replace the breaker powering that freezer to a 3A to 5A max breaker.

Hi house please I am new to solar, thinking of getting a 10kwh lithium battery, which brand is the best? Some told me about Cworth, blue carbon and felicity.

Kindly explain more of the No 3 please.

As for No 2, the total installed panels are not up to 6,000w.

The installer will be coming over the weekend to carryout a check to determine if there's a short circuit to frame or anything like that.


For number 3, go to settings, then battery, scroll to the second page, it has figures for maximum charge current and maximum discharge current.

Maximum charge current - set to anything you want. This is not important since your panel is not more than 6500w.
Maximum discharge current, leave it at 115A to accommodate startup surge of some appliances. If you set a lower limit, DC overcurrent will be reported when you try to draw more than that value from battery. But be sure that your total connected load is not more than 5kw.

If the above was already correct, (ie discharge current 115A limit) then the issue is number 1 as earlier stated.

When you say " buy it from someone" i want to assume its second hand

When did he buy it?

Does your friend have maintenance culture?

Are you sure the person did not know of the issue before selling?

Changing the electrolytes to resuscitate it , is 50-50 thing and since its cheaper to charge than buying new battery, i would suggest he try it first.

Just locate one good battery charger and give him go ahead



Yes,second hand...he bought like a month ago.
Thanks,so anybody that charges batteries can change electrolytes too?

Hey guys, hope the holiday is going well.

I posted here a few months back for info and advice on budget, I appreciate your replies.

However, I need your advice as I have upgraded my solar battery and panel but it's not doing what I want in terms of power supply.

I upgraded it this Monday to a second hand mercury 220 ah battery(one year used), 400W panel and 30A charge controller(which I find useless cos I don't understand how to really read it).

My major use of the power is for my laptop (90W) cos I work from home and I need to be able to cahrge it at least twice a day. No fridge or TV, just the laptop, DC fan, phone, and bulbs.

During the day it charges laptop fast and carries the fan without issues.

The problem is that the battery doesn't last after sun goes down. Charging phone doesn't seem to do anything to the battery, it's when I plug the fan or laptop after sun down, it will immediately start blinking indicating low battery. I feel like the battery has lost its strength or something else I don't know.

For today, I charged my laptop and phone with it around 12 pm, by past 2pm NEPA brought light, I turned it off, I didn't use it again till 9 pm and once I plugged the fan, it started indicating battery low again, so I removed the fan. But right now my laptop is fully charged but still plugged in but it's not blinking but once I plug the fan it starts indicating battery low... I didn't understand how that is working.

I need your expert advice because I intend to return it on Wednesday and get a 120 ah new gel battery(that's what I initially wanted to buy).

Thank you!

Re: Solar Energy, A Complement To FTA by Ferdiwar: 10:35pm On Jun 17
Thank you for your response.

The max charge/discharge current has always been on 0.5C since installation and the only thing that needs surge startup is the fridge as all my ACs are inverter AC. I'll adjust the the max discharge current to 115A and see how it goes.

What was the maximum discharge current value in the inverter before?

The battery could've been used for 2 years, or even if it's one year, the user may have abused it so much that capacity is heavily reduced. Also Mercury battery ain't top tier in lead acid battery league. These factors combined points to one thing, battery is now weak and recommended replaced. I'll suggest you return it and get a new battery. Consider a small lifepo4 battery, if budget will allow it. If the budget won't, go for the new lead acid battery. Cheers.

some solar panels exceed the rated wattage due to over favourable conditions.

have u tried another adapter? More also check the socket/extension you are connected to if there is any disconnected conductor.

Another question I want to ask if is ur inverter is grounded to earth?

Weak Tubular battery can be revived.....He needs a good battery charger to do that. Good hybrid inverters with high charging ampere can do that. Change or top the water and charge like you want to desulphate, it should work. But If he can return it, add more money and get a LiPO4 battery, its better in the long run

How my set up looks now.
if you were to choose between this your current setup and another setup made up of deye, but high voltage inverter (same rating in KW) and 61.44kwh of high voltage batteries, will you still settle for this one you have now?

So Tubular battery should have infinite lifespan then. Great.

50A

Re: Solar Energy, A Complement To FTA by mank1234(m): 10:33am On Jun 18
Ferdiwar:
50A

50A x 53V is just 2600W.
In the day, when sun is up, I'm sure your total load is more than that. During mppt tracking (for deye) solar output drops to 0W briefly and the load would be on battery.

Changing that to 115A, should solve your issue. Connect all your panel back and observe for some days.

Same way my 3.5kva inverter got destroyed by lightning and repairer was quoting almost 200,000 for new board and workmanship, i just kept it aside

I finally bought a 5kva 24v felicity

Does Felicity has 5kva inverter at 24v?
I thought 24v stopped at 3.5kva?
Please can you share more light on this?

check jumia you will even see it

I would had rather buy 50ah LifePO4 than a tubular of 220ah to power most important appliances. Now that there is lithium tubular, e don kuku ma finish be dat.

Worst case I will scrap out lithium ion from laptops and make a small build.

Tight budget crew...

My panels are acting up.

Twice now I've noticed them completely refusing to generate more than about 300w.

Sun is out, no evident shading, my friend using solar nearby is getting enough power from his array.

Jinko 3x 580w panels, ordered from Foauni. Right now they're only making about 280w. Battery isn't even charging, since the load I have on is taking in all of that.

Tried putting on a heavy appliance to see if it'll get the panels to send more power but nope, nothing.

Check the voltage readings from the panels to be sure it isn’t the charge controller that’s the culprit

There is Li mode on the Inverter, this has to do with Settings.

What type of batteries is it, and what are the charging Voltages? Lithium Bulk and Float must be the same.
Provide more information about the charge settings, Current and charging mode, etc.
