Pls i need digital battery level indicator

Dam5reey:


Something like this?

This was a small set up for 3 (5W 5V bulbs), also 1 charging point for phones..

fogechi:


something that can show me in %age the level of my battery

Oga GeorgeD1,

Battery replacement has been the biggest cost in offgrid systems for most people but somehow you have managed to draw appreciable longevity from your batteries. kindly educate us how you do this as well as telling us the configuration, brand, and maintenance strategy for these batteries.
I know you use Zenith but fake zenith abound now and i also know your previous batteries lasted long before replacement with 260AH zenith.
We need to learn as i got frustrated from premature failures and went lithium.

GeorgeD1:


hello dmerciful,
the secret to battery longevity is spread over a range of factors. it has everything to do with the battery type, charge
controller type, inverter type and usage habits. like i said in my last post, having a high end inverter which incorporates
a battery monitor system (bms) certainly has helped preserve my batteries by ensuring they never get depleted beyond
a preset value - and this works regardless of whether i'm home or not. with my previous inverter, i had to leave specific
instructions for my folks to follow whenever i'm going out of town. and this was always subject to abuse.
besides the bms and high end inverter, my wiring configuration also plays a huge role. i have four batteries wired in series
to make up 48v and three of these joined together with equal length of cable to make 12 batteries. in effect its like having
3 separate battery banks operating independently. this configuration ensures each bank receives an equal amount of
charging current from the cc while charging and also gives out equal amount of load current while discharging.
as for cc, I guess the saying that you get what you pay for is true especially for solar. in my experience, a large number of the so-called cheap and pocket friendly controllers flooding the market these days are nothing but battery killers. they either consistently undercharge or overcharge your batteries leading to premature failure. I have been using the tristar for over seven years now and over this period I'm happy to see best in class performance in terms of charging algorithm. until recently of course when I was forced to incorporate the midnite classic due to my solar array upgrade exigency.
lastly, i carry out yearly turn around maintenance on my battery bank. by this i mean battery rotation. i load test them to
confirm each battery's condition of health.

Hello house. I still have these 2 charge controllers for sale.

1.Roysolar charge controller 12/24v 60a

2. Roysolar 12/24v 20a

Interested? Call/sms/whasapp 08033735359.

RipVanWink:

Maam.u don waka reach here..
In addition to what the other fellow said.
U need to itemize all loads u intend to put on the system..determine how many hours they run.state the wattage also..so we can hv a clearer pic of ur setup....thats the proper way to do it...so u hv a well designed and balanced system.

The solar is also tied to the assignment above.
How many hrs of phcn do u get daily?

DMerciful:
Nicely put. Interesting to know you are now offgrid, this i wanted badly but due to space consideration in my current location i am still stuck with 1000W.

Regarding premature battery failure, sometimes there are many factors other than load why battery fails. for instance under-utilizing a battery might cause memory effect so it may be necessary to discharge appreciably once in a while and also equalize including AGM except gel. also there are a lot of fake batteries out there. Many inverters in the market have poor charging systems that cuts of before the batteries are fully charged thereby loosing capacity progressively.

but a general challenge is the high susceptibility of lead acid to failure especially if not well managed and maintained and this know-how might be too much for the average user and as such i strongly recommend the rugged lithium iron phosphate with upto 80% DOD with negligible capacity loss as well as absence of memory effect and acceptable high current draw. Mine is delivering like kilode!

Hello, Dam5reey sent u a simpler version which accurately reads battery voltage and you can always deduce SOC & DOD LBCO volt of your system ! I use same for years & it rarely dissapoints .. Cheers!!

harveyspec:


pls can I see a picture of this

JohnKester:


DMerciful

From what I read from Trojan literature regarding their flooded batteries, they were very emphatic that their flooded batteries DO NOT develop any form of memory at all. Is there a new development contrary to their assertion. Please let us know!

Cheers

Its exactly same Dam5reey posted above ... It actually reads DC voltages (120vdc max) .. I have few units remaining if interested !

0.8.1.3.5.0.3.1.9.5.1

pls can I see a picture of this

efuro:

Are you running DC volts AC?
And do you have idea of the difference BTW Low voltage AC and inverter AC(compressor-less AC).


Anyway any independence Awuoof sales?

Me Frank, I dey imagine the speed at which you will wake up from bed if you just that led volt meter display 23.0v by 2am.
I bet you you develop all kinds of fever.
Lol.
I love the monitoring device sha. The location you kept is just funny to me.

Been a while Bro. I am good sha. Trust you're as well. Cheers.

harveyspec:


don't see how these questions apply to me o

na DC battery monitor I request to see o

i nor see how compressor con enter the matter

barrezi,
high end inverters like magnum come with a battery monitor system (bms) as an add-on. this carries out the lvd function among others thereby protecting your system.
i can't count the number of times the bms has intervened to protect my batteries so far and in hind sight, maybe its another reason my batteries have gone nearly five years and still performing as new.

idsolar:
Who say sun no good. My modest upgrade to 1040w early august with rain/cloud overhang just clock cummulatv delivery of 100kw. Chai how much i for pay nepa for this? Solar is d way jo.

Barezzi:


At about N24 per kwh, na only N2,400.
Barely enough for a bottle of wine.

How much your upgrade cost you?

barrezi,
cost is only a tiny fraction of what comes into play when going for renewable energy.
let me flip the question the other way round: what is the cost of staying in darkness?
i guess the answer is zero naira? so if cost is our only consideration we might as well
decide to save the huge amount we have invested so far and remain in darkness while
waiting for the elusive phcn to supply us power whenever they deem fit. however, will
that be a good option? no?
so here comes the fuel guzzling, noisy generator to fill in the
gap for those long hours almighty phcn decides to keep us in darkness. and this is where
it gets really interesting: if mr idsolar had been running his generator for this length of
time (august till date) commensurate with the up-time of his charge controller, he
certainly would have spent enough money on fuel to buy his solar system all over again.
