Hello Fatin,
This is actually for an off-grid system so is not designed for powering a
building. If you want to connect it to the mains then the best is not to
use a battery and just attach the panels straight to a grid tie inverter
that is attached to the mains. I hope this helps.
All the best,
Jonny

All the wires are black. Why arent the positives red? How can you tell
which is which?

Great video, only problem your audio quality is very poor, you need to
purchase some wireless microphone

Jonny: Unfortunately there is not a single complete solar panel kit on the
whole of the market ,so I have to buy every piece of wire and connections
and so on separately .Like this most people are put off solar.It is rare to
see someone wiling to help people as much as you ,below so thanks.
What kind of wire did you use ?Is the amp for this wire important
?Should it be the same amp as the controller ?

Hey, what does the charge controller do!

What about fuses ? don’t we need fuses betwen the battery and de inverter,
and also betwen the charge controler and the battery?

Can you attach multiple batteries to the controller in parallel?

Can you tell me what is your charge controller ?

Always wrap the wire around a terminal post in the same direction that the
retaining nut is spun to tighten. You tightened the second connection at
the battery improperly. The wire you placed on the battery lug wrapped from
right to left around the lug. Then the nut was tightened from left to
right. The way you did it could result in the wire splaying out as the
rotation of the nut could force the wire outward away from the terminal
post. This can cause a connection to become lose, producing arcing and
start a fire. You got away with it in this demonstration because you
pinched the wire between two washers. But still it was done incorrectly and
in some situations would not pass an electrical inspection. I recommend
soldering all stranded wire ends prior to attaching in any manner in which
a crimp or pressure situation is used to secure it. That way you know that
there will be no splaying out of the wire strands and thus, no lose
connections in the future.

Jonny could u do a video on how to connect those smaller batteries like
those type of remote control ones u use to put in thx if u cant then its ok

Hi @aktsolar I have a question for you shouldnt the battery be connected to
the grid tie inverter so the energy powers the building?

to wire up two batteries and the batteries are all ready joined do you put
the pos one one battery and the neg on the other battery or to you put them
on the same battery

i couldnt here the ned part about questions so il ask here if ok, i wired
in my battery to my charge controller but not yet connected the solar panel
wires and the controller lcd screen has not displayed anythin, do i need to
wire the solar panel up to gt a lcd display? i have a 30amp 12/24 volt dc
compatible controller which is auto detecting the voltage. any ideas
please?

Hello there, No diodes are necessary as the controller has the necessary
diodes in it. Actually, adding diodes could have a detrimental effect as
there is generally a small voltage drop across a diode and this could
interfere with the way the controller tests the charge in the battery.
Cheers!!!!

hi jonny i have 4x 12v 135ah battery connected in parallel to give me a
total battery of 12v @ 540ah what sort of output wattage from a solar
pannel should i be looking at in order to do anything noticeable or
worthwhile to charge such a large battery?
AKT Solar says:

Hi there, Yes, although it’s not really dangerous as 175W is still
relatively low power, it is a good idea to cover such a large panel before
connecting it up to the controller. Otherwise it might spark when you
connect it. And just to check, if it’s a 12V system you’re creating then
you’ll need a 20A controller for a 175W panel. (If it’s a 24V system you’ll
only need a 10A controller though). Feel free to ask any further questions.
Good luck! Jonny

at last i have found this video, i was struggling on how to connect an AKT
solar panel to a battery..thanks for the guide.

never use car batteries with an inverter – you will ruin your battery. Car
batteries are designed to give quick burst of high current for ignition –
so they are made to charge & discharge very quickly – they are NOT meant to
run for long durations. Inverters need something called the ‘Deep cycle
battery’ [Google it] – i.e. batteries that hold charge for very long
durations – so your best bet is to buy a good deep cycle battery [they are
costlier than average car battery]

And to charge a battery bank containing more than one battery is also very
easy. Your bank should already have the batteries connected with the
positives of each battery connected together and the negatives connected
together. To charge the multiple batteries all you need to do is attach the
+ve output of the controller to one of the positives on the batteries and
the -ve to one of the negatives. The batteries will then automatically
equalise the charge that is put into them. Cheers, Jonnny

pretty easy to follow..

@3.45 you put the wire on the wrong direction, it should be clockwise, so
that as you tighten the nut it pulls the cable in.

Whereas if you’re only planning to use a maximum of about 500W from your
inverter then 500Ah of batteries and a circuit breaker of about 100A would
be fine.
