when you on the power outlet,the inverter will power on,it will supply light to the house

Okay, do you notice any difference in battery voltage once the inverter is powered on? Do you have a clamp meter to check if any form of current exists between the inverter and the battery? In/out

yes I have done that, no current exist

mctfopt:


Do you use NEPA or generator to charge?

I use NEPA and solar

obinna37:

And no difference in the battery voltage between when it's off-load and when the inverter has AC input? If yes then you may indeed have a faulty inverter. I once had a 1.5kva inverter, it stopped indicating the charge icon but it still charges the batteries.

ojeysky:


This is cool, I have a few of this BMS/Bluetooth for sale if anyone is interested....comes with a temperature sensor as well (though not so useful in our environment but still a good info source)

Sure

mctfopt:


Once did 114 on Makeskyblue and there was no issue except for fans virtually running all through when the sun is up. Had to go down to half to voltage for cooler runnings..

What was the system voltage when you had the 114v Voc?

yes,no voltage input in the battery, I think the inverter is faulty, can it be repair.

It's likely the charging section has failed. You have three options:

1) Repair it by a professional or open it by yourself and look for a fuse that is open.

2) Get an external charger.

3) Forget NEPA and use only solar.

Good day all,

Please can someone help me with a place preferably in Lagos that I can spot weld a pack of NiCD batteries.

Hmmm. Interesting.

Was the 114v a one off occurrence then or it's a constant? Also what is the usual common voc that you read on the CC, most times less than 100v?

Can you remember the Voc of your panel?

Used it for like a month. Decided no need stressing the SCC. This was due to the long distance (around 35m) the idea was then to reduce power loss and run smaller diameter wire. Had to upgrade wire and decided to run the smaller voltage with inherent higher current.

Good morning House....I discovered my battery(luminous 220v) doesn't perform well under high current charging, which resulted to greatly reduced runtimes. Called the installer couldn't profer a solution until by instinct I reduced the default charging current and gbam the battery started performing like when I bought them. Has anybody experienced this

@ Bolded.

That explains it all. And to say that I neither realized this fact nor read it in the manual all this while that I've had this CC in installations around.

I'll go thru the manual once again more carefully to see if it's noted there.

Thanks.



Thanks bàbá. Na me no read am well true true.

I run 320 watts panel so I guess your 210 watts panel enables you to do 3s on it.

My next soujourn will be around MakeSkyBlue. I need to determine that there are truly marked differences between the two and not just one calling the other bad name for the sake of it, even though they both have the same form factor.

Las las, e be like say na dem EPEVER go settle this matter the way this thing dey go.

I have always felt that makesky blue is the main coy while powr whatever are a copy. I mean makesky blue updates firmware, hardware etc.... Shiii is clear as day.

I'm working around the shipping price hurdle sha. I already have three MPPT CC, one pwm cc, and one cheapie cheap pwm cc. Yet i want to get this makeskyblue 60amps again.... ....i believeone day i go use them, for now na my landlord de winchywinchy me and solar matter.

Congrats on your migration to LTO. It is a giant leap indeed.

Please tell us more about your LTO batteries.

I know this post is old. Hope yoy don't mind.

I see that you now use this LTO batteries. What has the experience been like? And what made you pick it over other Lithium chemistries?

Thanks boss

obinna37:

I have the same issue. The inverter will show that is charging but no increment in the battery voltage. The system is designed for grid interconnection with 1100W array to charge 24V200AH bank. The problem is that it is always in use during the sunny hours thereby leaving the battery empty in the night.

obinna37:
I use NEPA and solar

can you help describe how you connect the inverter and solar to the battery bank because I guess the charges from the solar and the one from AC supply seems to be causing overload on the inverter panel.
I might be wrong but expert can put more light for us and possibly a detailed diagram for proper connection for future experiment.

I don't think is the same inverter, my will show CH,as sign of charging,but now it doesn't show the CH,it just display 99.1 as the batteries are charge. This the inverter model below

normal 24v inverter,see pix below

Hope expert in the house can give more input on my opinion above as my BTS inverter had a total shutdown and I was of believe that it was caused by thunderstorm but we I took it for repair it was said to be overload but I know my load was not more than 25% from indicator, so mind when to the connection with the solar.
so, as I suggested it might be most of this inverter can not tolerate seeing charging current from another source meeting at the battery terminal.
my 2kobo sense. I leave it to the expert

whats the charge voltage setting of your cc?.
if too high this sometimes affects the inverter.

charging a battery simulatneously with solar nd inverter is possible, have been doing this for years, what i notice is that depending on which charging source has higher incoming charging oltage at any point in time, that one will then have priority

It's usually nice to see the short period peaks on a sunny day during raining season

Hello All, So I have a quick question.
I am not so experienced with inverters and all so my question might be basic to some of you.
From my research, I read deep cycle batteries get bad when you use below 50 percent of its power consistently and when you overcharge.
I have a solar panel so my inverter is hardly ever dead or I hardly get to 50%, but how about overcharging?
Does the solar panel constantly charging it everyday damage the battery still?
The inverter is hybrid so it stops charging when the battery is full. So my problem is will the everyday usage affect it somehow?

That is my question.

this is nice 2314w out of 2520w panels. i cant wait to install mine soon.

PROs:

At more than 20,000 cycles, the LTO chemistry has the longest life of all the Lithium batteries.

It can be discharged to 0v without any serious consequence. Some manufactures actually ship them out at 0v state of charge. Some of mine were at 0v when I received them.

LTO does not combust due to overcharge or any other abuse. There are a lot of LTO abuse videos on YouTube.

It can be charged and discharged at a very high 'C" rate (10C or higher). You can fully charge a LTO battery in 6minutes if you have a capable charger.

I have used mine for over two years now and I have not noticed any loss of capacity. If I consume 300Ah, it will require less than 301Ah to recharge. The cycle efficiency of mine is 99.9%.

It does not heat up during charging of discharge. It stays at room temperature 24/7.

As at today, LTO is the best battery money can buy.

CONs:

It is much more expensive than other Lithium brands

It is heavy, So, it is not very suitable for mobile application

I didn't show main On? Check your input wires especially the breaker or fuse.
