The experiment seem to say otherwise and on the basis that it's not good to always charge an LFP to 100% I think between 13.6 and 13.8 may be better in the long run.

I quite agree with you in the sense that LFP doesn't really need to be charged 100% full.
Even at 14.4V it's still not at 100% that is why the BMS is very important to see that the battery doesn't achieve a 100% full charge, keeping it at 95% - 99% charged.

Its wise to keep your charge voltage under due to fact that your charging device may not have LFP charge function.

I just hope our LFP BMS are top notch to be able to save us from unforeseen situations that may arise due to mistakes or faulty chargers.

If you have opportunity to get a full charge is a plus since it's around 3.6V per cell and still very safe and doesn't affect battery life.

Good afternoon Nairalander DIYers.
Please, I need the expertise of the experts in the house.
I have two arrays of panels properly matched to two Fangpusun CCs FM60 & FM80. Both arrays are separated to its own CC and both are connected to same battery bank of 48V 200AH (4 X 200AH AGM Battery).
The system is intended to charge the battery for the night backup while the bulk of the installation is going to be used up during the day, the array is over sized for the battery bank.
My challenge is how to setup the charge controllers considering that the two CC are rated differently as 80A and 60A. I will appreciate enlightenment about which settings I have to set up on the charge controllers, I will like the two CC to share the loads.
The battery information is as follows;
AGM Deep Cycle
Model: MML12 – 200
Rating: 12V, 200AH
Charge at 25oC (constant Voltage) Float: 13.6 – 13.8V, Cycle: 14.4 – 15.0V
Initial Charging current less than 60A

Am just curious, how come it's that heavy? can you share reference to the battery as it must be built with some very heavy metal.

148K is half the weight of acid lead types. You can deeply discharge this.

I wasn't asking about the weight relative to lead acid, I was asking relative to other LFPs, it seem to be overpackaged thereby making it heavier unnecessarily

I need a good 1.5kva to 2.5kva hybrid inverter with MPPT CC (used or new). It should have adjustable voltage settings

Good day everyone, please where can I get 12kw/48v 3phase Hybrid Inverter? Thank you all.

Happy birthday to you

Thank you sir.

Good evening sirs... Please can a 650v ups effectively charge a 18amps battery.......please I need ur replies

Hello house,

Please i am trying to install a solar panel system for my parents, can you recommend a good solar installer in Ilorin?

Secondly, I want to ask if anyone can help with the schematic drawing for hybrid inverter connection. I am not an expert but I try to read up, and from my readings, it seems that the connection of solar hybrid inverter is different from the normal solar-inverter connection.

Thirdly, I assume I don't need a charge controller if I am using a hybrid inverter...please help clarify.

Lastly, what is the recommended cable size and type for connection from the panels to the inverter....this is so that if I don't get a recommended installer, I can at least monitor the one I can manage to get to ensure a good connection.

Thanks house.

Apologies... Just seeing this. Been away from this section for a long time now.
Yes I'm in Ilorin.
I'm sure your system would have been up and running now.
You can always call me incase u need some extra help anytime.

No, it will be very slow

1. Anyone with 16mm dual cable?

2. I want to change from 12v to 24 v inverter. Since I already have 60a pwm and 60a mppt CC, do I go for hybrid inverter or ordinary inverter .

3. Pls recommend a inexpensive but good inverter of 1.5 to 2.4 kva based on 2 above.

4. Anyone using inverter gotten off aliexpress that is pure sine wave that meets 3 above? Pls share the link.
Thanks

This birthday, I'm once again reminded of the bountiful joy that I've reaped from my family and friends, and how blessed I'm to have so much love from everyone around me, thank y’all from the bottom of my heart.. it’s all love ❤️ from this side!!

Shalom!

ceaser:


Okay. Thanks.

Hello Ceaser how do you know when Ur bank is full? Been charging since yesterday and it's stuck at 12.7v.

By the way, got the cable and accessories from AliExpress, so far it works okay on my laptop but really doesn't last, guess my 18650 batteries are bad.

Anyone with good deals on original 18650 batteries.?

Penuelseun:
No, it will be very slow

Alright thanks.... So what do I do? Buy a battery charger? Which one is best for such battery... Thanks... Happy Sunday

Penuelseun:
No, it will be very slow

Read it well. He said 18ah battery..going by the 10% batt charging re. This implies 1.8amps.
Am fairly certain a 650va ups will be outputting something close to that.if not more

Happy belated birthday bro! Nice doing business with you.

Colleagues I like to I have a 3kva hybrid felicity. It has a 1500w limit. I am considering oversizing it to be 3s3p, my panel is 250w with max voc of 36v. I need advice on whether it's too much or fine?
