Am sure ur PV are in parallel . I can't just take my eyes off ur low wattage and high amps.

Magnificent harvest! Ur batteries will love you.

Ijeoma660:
Today, I reconfigured the array from a 4nos parallel system to a 2series, 2parallel configuration. With the hope of stepping up the voltage headroom to be potentially converted to current. Also with higher voltage along the 10-metre PV supply line , less losses.

See before and after pictures and share any comments you might have please.

I have a 290 w canadian solar panel for sale. It is less than a month old. Reason for sale: I need to replace it with 2 150W panels. Price 50K. Will deliver to Mainland Lagos.

chris81964:
If you did that and are getting more than 30 V from your PV. They are bigger than 100 Watts. Your voltage will be in the high teens after the controller kicks in on 100 watt panels.
Do you have the manual? You might want to connect them in series, thinner cables, longer distances and better efficiency. Good luck welcome to our world. The most I saw out of 2600 watts today was a little under 1500 watts. So if you are seeing over 300, you might really have 150 to 200 watt panels.

Oga Chris. Good day to you.

What angles for solar panel mounting have you found to yield the best results?

I am about to experiment with an unconventional arrangement of a small solar array in my family home and I would very much like to squeeze maximum juice from the array.

You have more 400 watts in PV if you are in Lagos. It looks good. Is that the 60 amp controller made by Voltronic? works fin on AGM batteries

makavele:
I thought you had an MPPT CC; why did you have to parallel all four panels
My guess was good then!

makavele:
Are you sure that CC is an MPPT type ?
By my calculations, it is stepping down the voltage to battery level ( and multiplying by charging amperes) to give Power..
Without upping the charging current using the extra voltage . . . Maybe I didn't check it well, will do again . . .

Not bad at all, but in the end, how did you string the panels?

By 7 A.M, I am already seeing about circa 150 Watts, though on a larger array !!

@mcTrinity @NiyiOmoIyunade @makavele

Thank you for all the selfless support you are providing here...

Please I am about setting up and commencing my DIY solar project. I have

i. a 3KW, 60A mppt CC
ii. 4nos PV panels whose capacity [wattage] were not stated but made by afromedia. i assume they about 250w each. I think I was wrong in my assumption as I later realised the panels were under 100w each.
iii. 1.4KVA inverter and
iv. 2x200AH deep cycle batteries

Kindly advice what size and type of cable I require between the pv panels and the CC. The distance from pv panel to CC is estimated around 12m max.

mcTrinity:
what's the inverter voltage system?

and there must be a rating on the panel... Vmp or Imp or something. check well

thanks

DMerciful:
For my EPsolar, itracer 60A, i use 2 breakers. One breaker which is a double pole breaker of 40A is btw the PV and CC lines. The other breaker of 80A double pole is btw the CC and battery. Here i only protect the positive terminal with one pole while the remaining free pole is use to break the PV input positive. This way, anythime the CC-battery breaker trips, there is no PV input to the CC

APC be careful, hausa fulani know these unpredictable people more than you and they keep them at arm's length, they never give them chance to operate in Kano but we allowed them to be yet they abuse Yoruba silly and slogan "Lagos is no man's land. I ofe nmanu hate Biafra with passion.
