a serious buyer will not suddenly become interested because of attached prices. this thread is for solar energy discussion, not my own marketplace. i post for only interested persons to contact me and seal deals.

I normally challenge those who don't add price to their items and I will say the same to you....there is really no excuse for not adding price. So Oga Valto do add price, if buyer is interested he will reachout

ojesymsym:
Do you have a direct link to this new one that makes this claim of being able to wake up a sleeping BMS on protection mode?

Here is the link to Aliexpress shop

nice point bro

Again, this is not entirely correct. There is something called Impulse Buying. It is a major concept in Economics and happens when buyers make a decision to buy on the spot, on the basis of having the minimum required information (which definitely includes knowing the price of the item). Everyone buys on impulse at some point. A significant percentage of sales is made through impulsive buying. You are really leaving a lot of money on the table.

However, I definitely respect your stand, bro. Cheers...

Must you guys always bring tribalism and religion into every single thing?? Didn't it occur to you that his decision could be based on his personality, fuelled by his experiences and NOT necessarily due to his ethnicity? Na wa! This is the reason why Nigeria keeps being backward. We keeping taking tribalistic and religious stand EVERYTIME

Why are you responding, he has a dirty agenda.

You have done the same thing. You just added religion

Valto:
nice point bro

Na wa o... that's the only section you found important?.... It is well o.

No, I didn't get those devices, I went directly to their office, told them what I wanted and they programed the inverter appropriately

After they programed it, how do you manage to know (how long the battery will last you, how long it will take to charge full and the percentage of load the inverter has carried)?

Sorry for these questions oh, but I just need clarity based on the fact that you have first hand experience on the tbb.

odimbannamdi:


It mustn't be stated. You should be able to set it manually by yourself.

The Pow Mr CC, for instance, has profiles for different battery types. Within each battery profile, you can also set the floating and absorption voltages. You can choose as high 16.0v as floating voltage and 17.0v as absorption voltage. But i honestly don't know which of the stated profiles should suit tubular batteries. I am guessing Sealed thiugh. Hopefully, veterans will clarify.

Understand nwanne nwoke, gracias!

Them really no dey waste time oh.

The new redesigned PowMr MPPT 60A Solar Charger Controller @ Odimbannamdi posted about some days back, claims it has a reactivation function to awaken a sleeping Lithium Battery BMS

Hehehe. I guess we'll need first hand user experience to confirm if their claim is true.

We will have to wait for someone here to procure it.

I've actually deployed like three units in service but for LA.

For the load on inverter,
You may need external peripherals for that. For example, add a wattmeter or limiter that gives details of output voltage and current. That's what I did for an installation with TBB inverter.

And you may be asking for too much when asking for how long the battery would take to charge full or how long it'll last. Most inverters don't provide this information too, you may be able to estimate it based on other devices & plugins (Charge controller that logs, BMS that communicates, in-line amp meters etc etc )or history.


Possibly your next question would be to ask for Charge controllers that logs etc? lol

While not intending to ruin your parade, I hope you don't end up in a questioning loop/abyss. You need to take a decision based on the myriads of information provided to you(for some weeks now) while taking into consideration your constraints (budget, load, environment).

Hello.
I have a 1200watt solar panel at 24v, 100A charge controller and a 5kw felicity lithium battery at 24v.

I installed these a couple days ago, although the sun inst stable my light has been on 24/7 since then with most applies working during the day.

The problem I have now is the battery won't charge above the solar panel voltage to attain full charge, the highest the battery ever charged is 27v, that's like 60 percent charge I think. I think the moment the panel voltage equals the battery voltage it stops charging.

What can I do about this.

What settings are your charge controller set to? Also in what configuration are your panels arranged to?

I don't know how to set the charge controller.

It's all connected in parallel, 24v 200w x 6 in parallel

Moneyboyz:

You should get another installer to take a second look at your system. Your location maybe someone here is close by

Moneyboyz:

Dude, if you have money for Felicity lithium battery, you should also invest wisely in a much better cc

Moneyboyz:

First your charge controller is PWM not MPPT, secondly, confirm the settings on your CC, thirdly,confirm the orientation of ur panels.
Then lastly, if possible ask your installer to change the configuration of your panels to 2s3p as I believe this is more optimal.

NB: These are simply my thoughts....... Others will add and correct... Cheers

Recommend one I can use, I will go and buy it asap.
I shutdown the whole system and measured the voltage with a meter it was at 41v.
I restarted the system and the controller stepped it down to 26.5 to 27.5 v the amps can go as high as 50amps.
Is it normal for 24v 1200w parallel to go as high as 41v+?
if yes what controller should I invest in for better performance.

Moneyboyz:

If the cc is real mppt then increase the incoming voltage.
2s3p like somoeone said

24v panels are roughly 40v.

the controller is pwm, how can you achieve that?

OkoroPeugeot:
Ps I have a DIY installation & would like to add fuses and circuit breakers to it

I'm confused at the sizing

- 2 350W ground mounted solar panels connected in series with 9 meters of 10mm DC wire from panels to inverter

- 3kv 24V axpert inverter with 100VoC, 1000W rated power and 30 - 80vdc operating voltage

- 24v 100AH LiFePo4 battery pack (also conected with 10mm wire to the inverter)


I haven't connected AC charging yet as I don't want nepa to damage my property with their random voltage.


Please what do I need to buy to protect my setup? Been browsing and very confused.

Please how much does it cost normally to mount 2 solar panels on the roof of a Bungalow in Port Harcourt.

I moved to a new place and want to do a roof mount as no floor space but the prices I'm hearing I don't understand.

Every other connection is okay just to put the panels with existing wire.

Moneyboyz:


I don't know how to set the charge controller.

6pcs of 200w panels in parallel will deliver a copious amount of amps... Thise cables I am seeing seem like you will be loosing significant harvest from cables loss.

That proposed configuration will be useful with an mppt more than a pwm.
