This is my solar set up..

I forgot to add that my charge controller is the 60amps mppt charge controller


Please I need an advice on how to get the best out of my system.. thank you all in advance

VICTRON MPPT CHARGE CONTROLLER 150V/85A @200k

PLS CALL OLA ON 09057285592

PV voltage up to 150 V
The BlueSolar MPPT 150/70 and 150/85 charge controllers will charge a lower nominal-voltage battery from a
higher nominal voltage PV array.
The controller will automatically adjust to a 12, 24, 36, or 48V nominal battery voltage.
Ultra-fast Maximum Power Point Tracking (MPPT)
Especially in case of a clouded sky, when light intensity is changing continuously, an ultra-fast MPPT controller
will improve energy harvest by up to 30% compared to PWM charge controllers and by up to 10% compared to
slower MPPT controllers.
Advanced Maximum Power Point Detection in case of partial shading conditions
If partial shading occurs, two or more maximum power points may be present on the power-voltage curve.
Conventional MPPT’s tend to lock to a local MPP, which may not be the optimum MPP.
The innovative BlueSolar algorithm will always maximize energy harvest by locking to the optimum MPP.
Outstanding conversion efficiency
Maximum efficiency exceeds 98%. Full output current up to 40°C (104°F).
Flexible charge algorithm
Several preconfigured algorithms. One user programmable algorithm.
Manual or automatic equalisation.
Battery temperature sensor. Battery voltage sense option.
Programmable auxiliary relay
For alarm or generator start purposes
Extensive electronic protection
Over-temperature protection and power derating when temperature is high.
PV short circuit and PV reverse polarity protection.
Reverse current protection.
CAN bus
To parallel up to 25 units, to connect to a ColorControl panel or to connect to a CAN bus network

Thanks for your inputs.. I have decided to provide pictures hopefully that would help to find a solution to my problem


Secondly I would like to know how to equalize my battery.. do I have to charge it without powering my system on..? I hope that doesn't sound too naive..

Basically my average loads include
3 ceiling fans
Bulbs
Samsung Fridge(which I usually turn off by 6pm)

I have had the opportunity of doing business with kiekie and I can authoritatively say that he doesn't value his customers, very rude and money is all that matters to me..

You will even send him message on his personal number he will be forming too busy..

I am not here to spoil business for u oo but the way you conduct business doesn't leave a good impression on anyone..

earthrealm:


from ur pic, can see ur cc is epsolar , its same type am using.
your problem is too fold.
cos ur panels are not placed optimally..they are not generating enuff juice to charge ur bank, generally u need C/10 amps for flooded batteries...ie if ur batt is 200amps...u need a charging current of 200/8=25amps minimum to charge them optimally and prevent sulphation.

2ndly go into the settings of ur cc, and select ur charging voltages, in there u will also see the equalization setting which is every month...select 15.5v per battery as equalization voltage.

i hv 6 x 250w 24v panels with 60amps epsolar cc, my output hits 1270w/45amps, though the avg is about 27amps- 35amps

JUO:
please did you pay for installation?

sensisosu:


Boss, I have a 8 250w mono solar panels, I tried going into settings in my epsolar charge controller and couldn't find where to get the equalization settings.. please I would love if you can give me more elaborate explanation and how to go about this..

How can I get this 6deg to give my solar panels the right elevation.. ?

I should be getting more from my system than what I am getting now.. please help out

sensisosu:



Boss yes I paid for it.. but what do I know? I'm a novice hence why I have come to this forum for help from gurus like you.. your input will highly be appreciated. Thank you

Team DIY,

I am monitoring and inspecting my proposed site for the solar panel installation and these questions arise, I need the expert advice;

1. I observed that the area where I am proposing to install has the shadow of electric wire line (small line shadow) and small portion of the electric pole shadow that pass through the place around 2:45pm (Note I have limited space to install)

2. Whats the maximum distance between the Solar panels and the Charge controller, also between the charge controller and the battery or as long the cable are properly sized it doesn't matter?

3. Is it compulsory to install the surge controller with every installation, if so what type is cheaper and effective, where could i source this, for the combiner box must it be OEM type or can one get one locally or fabricate or is there a make shift type that could be used as I do not see so much specialty in combiner box as it looks like a small DB could be used for combining.

4. If I have two banks of battery 48VDC, 4 X 200Ah with two independent 3.5KVA inverters to each bank and I want a single PV system to charge the two banks, is it possible and if possible how will the battery configuration / connection be, also from calculation and experience what wattage of PV panels will be able to effectively charge the two bank together.

Thanks team for all help.

BUY NIJA PRODUCTS

please I need information on AUXANO SOLAR Products and price

has anyone had experience with their hybrid inverter or mppt CC or their actual pv rating ?

Do they have auxano ba3 too?

do they have extended warranty on their products?

thanks!

1. I observed that the area where I am proposing to install has the shadow of electric wire line (small line shadow) and small portion of the electric pole shadow that pass through the place around 2:45pm (Note I have limited space to install)-since you are constrained by space, get a panel with high Voc so you can do 2 x n (where n=2, 3 , 4 ) that way when one string has shadow other strings strings continue producing appreciable power. ensure your wires are thick enuf.

2. Whats the maximum distance between the Solar panels and the Charge controller, also between the charge controller and the battery or as long the cable are properly sized it doesn't matter? Normally if the distance is long then higher panel voltage is advised however based on the reco i gave in point 1 above, i will recomend the distance be as short as possible and use pretty thick cables(16mm and above).for CC to battery, limit to under 2m cable lenth and 16mm thickness

3. Is it compulsory to install the surge controller with every installation, if so what type is cheaper and effective, where could i source this, for the combiner box must it be OEM type or can one get one locally or fabricate or is there a make shift type that could be used as I do not see so much specialty in combiner box as it looks like a small DB could be used for combining.-its prudent to install surge protector abi you wan compare the small amount wey u go spend for surge protector with the high cost of ur cc and inverter? where to source? buzz me tru my signature.

4. If I have two banks of battery 48VDC, 4 X 200Ah with two independent 3.5KVA inverters to each bank and I want a single PV system to charge the two banks, is it possible and if possible how will the battery configuration / connection be, also from calculation and experience what wattage of PV panels will be able to effectively charge the two bank together.Best thing is to split the panels to two systems as well. are u worried about the cost of double CC? its more or less almost same to get 1 big cc or 2 small-medium cc.

i hope i've been able to help...let me know if u need more clarification

Thanks team for all help.

Might look like tough love but sir you need to do some home work yourself.. The equalisation setting is in your controller manual. Might want to read up on battery charging for deep cycle battery. There is no short cut to knowledge you just have to have the craving to learn.

From the pictures you posted here are my observation

Batteries are mixed. Never. Good thing to mix different batteries : trojan and different tubular batteries all have different internal resistance .. Also are those batteries new? I doubt it. Mixing batteries will slow the weaker battery drain the bank and the stronger one get over charged and damaged.

Also your battery cable seem too thin for your setup. You can't get optimal charge with those cables.

You are yet to tell what direction your solar panels are facing east west north or south.

my cc setup is in the villa, so cant guide you tru the steps..but download the manual and read..u will see how to set it.
its just after where you would specify ur batt bank capacity in AH.

@bolded, i explained that you need to buy solar racks with adjustable legs!.
see the attached picture, maybe you would understand.for such a steep roof..laying your panels flat is a big NO NO

Bought the 48v mppt controller, opened it and did not see the characteristics inductor(toroidal coils), i returned it sharpaly to the seller . their inverter algorithm is nice though

Good evening Boss... Can you give few update on the 100AH Lithium battery.. how is the performance like, after a month... how do you charge it..?

DMerciful:
Its been awesome. connected it to my inverter and charge with the inverter or cc. i have a battery switch that allows me to select either the lithium bank, the flooded battery bank or both. I mostly use both combine in order to reduced the charging current going into the lithium. Highly recomended.

The solar racks introduce another factor of wind resistance.
There is a tendency for wind to rip them off the roof.
