|Re: Inverter Users : Lets Have Your Experience by Feshizzy(m): 12:23am On Jan 14|
Good Day Everyone,
I do have a safepower 3.5kva 48v inverter for 2 year+
But I noticed an issue with it,
Before now, while charging;
It's indicates it current bar then continue upwards,
In the sense that, if it was remaining 2 bars before (2/4),
When it starts charging it goes from 2/4, 3/4 4/4 back to 2/4 in that circle till it gain a bar and so on it gets full,
But of recent after getting some new batteries,
For a while now I noticed it doesn't operates in such fashion anymore, now it starts from 0/4 to 4/4 ( even if it was remaining 3/4 bar before) circle till it shows "fully charged" and by then the batteries are literally hissing.
Please is this normal from anyone experience?
Or has the charging algorithm gone bad? If so, is it fixable? Has anyone else had such issue with their inverter and noticed any form of overcharging?
I do appreciate and await a response

how many solar panels do I need for 200ah battery
|Re: Inverter Users : Lets Have Your Experience by kiekie1: 11:19pm On Jan 14|
Hello, let's assume you practically discharge your 200ah battery to 50% everynight;
you would be consuming just about 1.2KwH
And you need at least 400Watts of panel power to recharge the battery back in about 4 hours sunlight . . .
I mentioned 400 Watts because it would be downplayed to about 300W x 4 hrs= 1.2kwH considering conversion losses . .
Thats just the basics . . If you wish to power some loads during the day(opportunistic loads), therefore you would need to add more panels;
depending on power requirement.
Your questions is totally dependent on your daily consumption . you need to put back what you have consumed daily with min of 4hours sunlight or 6hour's sunlight daily pending on your state / geographical location . You must also consider losses due to heat, cable length, unsteady weather ,solar panel standard, partial shading, panel inclination-positioning etc .. Experienced installers tag 100w panels to be 75-80w, while some tag 100w to be 50-60w panels as some Chinese panels perform below average of it's rated nameplate "50% efficiency" on the short run !
Therefore , for your 12v 200a power system , I will advice you get 150w 12v panel for a start as the higher the panel ratings/output -the better . Add one more making it 150w×2 later on ... I strongly advice against 100w not that it won't work but why not go for 150w when price margin between the 2 isn't above 5-8k considering futuristic loads et al.. Cheer's
