hmmm that dirty girl

DMerciful:
Sun wasn't that great today and depends on he direction ur panels are facing. They should almost be horizontal but 6• facing south

Oshomo12:
Not at all! If you were scammed, u wouldn't even see the panels talk less of the 27a u saw! Other factors play out too( is d panels facing south, DMerciful talked about it to lie wethin 6 degr{tilt angle}, what is the diameter of the wire frm panel-Cc, are de connected in series or parallel, etc.)

Note: look for the third eye(pro installer) to check it out for u.
U will need additional 600 w to really make those batteries happy( except u have a good Phcn supply and ur inverter can push in around 40 a)

Oshomo12:
I am lost here, 600 w 12 v system( aside your previous installation)?

Just gone thru ur initial post, 600 w 12v @80% panel effnecy and co; u should see around 38-40A (ALL STUFF TAKEN CARE OF!)

DMerciful:
You wey be guru for FTA, i think say u go get multimeter!loool. Anyways, go to an electrical store u will find it or borrow from the electrician near you or get a professional installer

Having a digital multi-meter or other reliable method to measure voltage is a compulsory requirement for anyone who lives off batteries.

Knowing the battery voltage gives you a fair idea of battery state of charge and health or otherwise and can help spot potential trouble (weakening or failing battery, battery overcharging e.t.c.) before it becomes a big deal.

Beyond ability to measure voltage, one also needs to be able to track the DC amps going in and out of his/her battery bank - without the ability to measure DC voltage and DC amps reliably, you are essentially in the dark about what is going on with your system.

You can get a very basic entry level multi-meter for like 2,500 Naira (measurements may not be very reliable) and budget at least 15k for a decent meter which has DC amps and voltage measurements.

Chinese brands like UniT, Mastech, Extech, EtekCity e.t.c are good value but you will never go wrong with the more premium offerings e.g. a 'Fluke' or 'Amprobe' or 'Klein Tools' meter if you can afford it. Other house members can suggest other good names they have experience with...

I own several Flukes including the Fluke 117 Electrician's MultiMeter and the venerable Fluke 376 and an Amprobe, I could no longer bring myself to touch or use the UniT's I had after I experienced a Fluke meter for the first time so I gave them out.

Regardless UniT UT210E and UT210A are good value and can be had for between 15k and 20k - they have both DC amps (critical to have for any one who wants to monitor/improve his system performance) and DC voltage measurements as well as AC measurements too although I find their AC Frequency (Hz) readings rather finicky/unreliable but they are more than sufficient for DC amps and volts measurements.

If you choose to go with any other meters, please verify that they can do both DC voltage and DC Amps measurement or you can take the plunge and just splurge on a battery monitor but a good multi-meter with DC Amps and Volts measurements is really all you need.

makavele:
How do you it was drained? Did you check the voltage reading this morning?

Do not use the battery bar indicator as it gives false readings.

Check the voltage of each battery with a multimeter and let us know what you get.

makavele:
p.s.: you need to double your panels... 600 Watts panels cannot sufficiently charge 400ah battery bank;

unless you are discharging to only about 80% each night.

makavele:
it is not discharging . . . the load mode is turned on . . .

these tier 2 charge controllers usually have 2 extra ports where you can connect light DC loads like led bulbs and a small dc fan etc.

they are not meant for large loads. .

it has different modes.. it could come on automatically at a preset time; go off automatically, enabled or disabled.

in my case, it comes on around 10am and goes off around 6pm; because i use it to power a small dc fan

which cools the mppt during operation
If you don't like seeing the icon, just disable it.

Those moderators always banning us , volcano n thunder wud plaster their left intestine

That the moderator always pushing big brother to front page, olumo rock wud fall on his hand

That Seun wud find his missing rib this year

That the pictures of the moderators wud be revealed to us , so that we can pursue them n bite them when we see them




Seun if ur mod ban me today ehn , I go go on hunger strike
