I guess you intend to type 480 watt-hour (12v 40 ah) battery and I'll wager it's those blue coloured lithium types. If I'm correct, you should get the functions of the four terminal wires correctly (2 input and 2 output) wires.

You also connected it directly to the 80 watts panel which isn't good for the battery. There should be a charge controller in between the two. You can get by with a small sized - maybe 10A to 20A - charge controller; one with bulk of 14.4v and float of 13.7v should be fine. If you also have a DC-DC buck controller with 14.4v output lying around, you can co-opt that too, better still if the buck controller has adjustable output voltage. The PWM charge controller should be able to provide you with info on your charging status. Some DC-DC buck controller, especially the ones with adjustable output voltage and current also come with voltmeter which you can read to guess your charging status.

About charging your phone, just get a cheapie car usb charger (shouldn't be more than 1k5), connect it to the output terminals of your battery and you're good to go. Of it's a PWM charge controller that you are able to lay your hands on, get ones with 5v usb ports included.

essegis:


Terminals on the battery relate to the individual cells that make it up. Each comes with their positive & negative terminal which you have to parallel to get the full AH as printed on the battery. Number of cells is determined by the amount of AH on offer.

From here you connect in series to make up your desired bank voltage. Remember the batteries are nominal 2v. Quite easy to get around though.

mctfopt:


Don't be confused, each side (made up of three terminals) is either positive or negative. But this is a massive capacity so only one terminal won't be enough to handle the current that can be drawn from it.

Notice how someone used a long bar on first battery to join the battery terminal. On second attached picture you can see that is a 48v system if you follow the connection, just assume each three cables coming from each battery is one to further simplify it.

GeorgeD1:


i see that essegis already answered you earlier.

in addition, you can always check the product data sheet for the correct battery terminal connection
sequence. where i had issues personally was how to connect both ends of the curve, since i had mine
in a double row fashion. for this i spent countless hours searching youtube videos of different types
of 2v battery connections without success until i eventually figured it out by myself.

Well, you tried with the data, you posted, but a bit incomplete. Flooded batts require 14.5v to 15v charging voltage during absorb, and 23.8v during float. In bulk stage, it gradually ramps up from 13.1v, depending on how depleted the battery is.

Luminous inverters hv poor charging alogorithm, hv always said this, unless you have solar with good cc, i would not advice anyone to buy luminous inverter, worse still for flooded batts.

If 13.8v is the max voltage your inverter is sending out @ 12amps, then your battery are in an unhappy state, and would fail prematurely. C/10 charge rate implies a 200ah batt requires 20 to 25amps charging current to be happy

2ndly, periodic equalization, wch is simply sending higher voltage 15.1v to 15.5v every 2 to 3 months for 2 to 4hrs.you need an inverter or CC capable of doing this

Hi Litaninja,

The solar na suffer part will only apply when your design doesn't capture DOA (Days of Autonomy) There will be rainy days and you should size your battery bank to accommodate worst case scenario to be able to enjoy the benefits of solar. Unfortunately the cost of the adjoining components makes people start small making it impossible to do what is termed best practice. Disposable income also has a large part in affecting DOA. If you are blessed, you tow that line, if not you go very basic and complement with either generators or the grid.

ceaser:


The first picture.
Two inverters??

The voltage stabilizer is for PHCH right?

ojeysky:

If the felicity actual capacity is 150AH/48V and not 120AH and if the cells are new then I think it's a good deal at that price.

My community has light supply 7pm to 8am everyday,so I need a small inverter I can use for atleast 8-10hrs when there's no light...I'm a corp member somewhere in Bayelsa so I'm looking for a good small inverter that can just charge my laptop,phone and Bluetooth speaker.

Any suggestions please?

litaninja:
Lmao. The design captures DOA ooo.....it is the pocket that lost it again the way some governments are losing BH terrorists.

Trippledots:


Boss, pls at what average C rate did you charge and discharge those zeniths with while they were in service?

ojeysky:


That should be roughly 100w or less. You could get a small 500w inverter and a 150AH battery so that keeps things at 50% DoD

icjunior:


How can I get these please,thanks.

olopan:
We have a similar package that can suit this your needs
It's a 500W inverter/charger with 100Ah battery.
Though ours is with solar but based on your needs, it can still work, as I believe your laptop isn't in use at those 10hrs period.

Kindly reply to proceed further.

Barezzi:
So it's actually 120Ah?
This one pass highway robbery if true.

Edit: I was already salivating at the prospect of stacking 5 of them to get 1000Ah 48V dc lithium bank!

Good day people,
I’m brand spanking new on this thread and I need advice/direction on a backup power system.
Currently I have a modified 2kva Prag inverter and 2 pcs of 200AH gel batteries that have gotten to their end of life (don’t back up for more than 30mins anymore).
Because of the recent increase in power tariffs across the country, I am looking towards an inverter system that would help to bring down my power cost by getting a hybrid inverter that places priority on solar before the grid.
To achieve what I stated above, I recently acquired 4 pcs of of 250w panel (1000w),
With the panels I intend to buy a hybrid inverter (looking at Schneider Electric Homaya 1.5KVA Solar Hybrid Inverter) and 2 pcs of Eastman Tubular Battery 220Ah 12V.
My issue now is
1. I’m not sure if the Schneider Hybrid inverter comes with its own Charge control (either pwm of mppt).
2. Also regards of if it does can I still get a 60A mppt CC that will handle charging and not compromise they hybrid nature of the invert (placing priority on solar 1st).
3. Is der anyother way I could achieve my overall objective without said inverter (Schneider Electric Homaya 1.5KVA Solar Hybrid Inverter) if that is the bottle neck.

Lol. Bàbá wan hit jackpot

wilmaria14:

Most of u don't get dis hybrid or not always get a CC for ur systems it helps it alot most of u buy hybrid and will not add a MPPT charger to it most all hybrid comes with PWM controller and for me anything more Dan 1kva need a MPPT charger control for it to work well dat is mistake most people do so
1 if u are going for hybrid or not buy a 60a MPPT
To cost it less buy ur normal 2kva inverter and den buy MPPT charger control for it
U can still buy 2kva diamond inverter one of d best with low cost but most people dont know
