@dreamflyin , also what size of cable did you ue to connect the panels to the CC/...Also whats the distance

still available

Distance is not much. The floor under the roof.
Cable are good quality PV cables.

Dreamflyin:

Cable are good quality PV cables.

The cables might be good quality, but under sized. Hence why he is asking you for the size I.e. Cross sectional area.

If undersized, your voltage drop especially for your 24V (or whatever it is) will be significant.

Maybe check and come back to him so he can advice you?

I'm tired of the poor harvest from my 2kw pv array by the PWMs installed.
Imagine am yet to see more than 24amp harvest for a 4 battery bank of 200aH any day.

Please anyone selling 80amp MPPT or 40amp MPPTs?

Something must certainly be wrong with ur set up. In as much as pwm is not effective as mppt, its still not doing bad on a small set up. Using my self as an example, 4 of my 150watts panel(600watts) are connected to my 30amp charge controller, and the minimum I get on a rainy or cloudy day is 35amps. This days that we no more experience rain in the middle belt area of nigeria, I harvest up to 60 amps. I formally had the same complaints u're giving currently but luckily I ran into a well experienced installer who discovered that my wires were seriously undersized. After installing the right wires I recorded a great improvement in my harvest. Contact an installer to have a critical look at ur set up and I believe u will be fine.

Does anyone on this thread have an Outback Mate 3 that they can rent to me for a couple of days. I got a VFRX 3048 and a Mate 2 without realizing that the new VFRX models are incompatible with the Mate 2.

At 12.00 noon, both PWMs harvests around 24amps(12amps individually).
Explain what you mean by undersized wires, please.

When using pwn charge controller, your harvest is not determined by array wattage nor by array voltage but by array current. PWM will trim your array voltage to battery range without a commensurate increase in current unlike MPPT charge controller. With larger wattage panel you might be missing out. The following example will make this clearer.

Assuming you have two 200W panel with following specifications in parallel: 45Voc, 39Vmp, 5.13Imp, 8Isc (all ficticious). Assume system voltage of 24V.
Using PWM CC: current to your battery will be 2x5.13=10.26A at voltage of 24V
This is equivalent to 246.24W out of a potential 400W from the panel.
Using MPPT CC: current to battery will be 400W/24V = 16.67A
Power delivered will be 400W.

If however, you connect the panel in series:
Using PWM CC: the current will be 5.13 and power delivered will be 5.13x24=123.12W
Using MPPT CC: you'll still get same as before.

From the foregoing, you can see that how connect your panel really matter especially if using PWM.

My suggestion, if you're using PWM and your panel Vmp is above your battery bank voltage, only parallel your panel (never series them), else you'll compound your already precarious situation (loss inherent in PWM)

If the panel is properly matched, next check should be your cable size. It might be dropping voltage making your setup to only at times that Vmp is above battery voltage (few hours).

Mount angle, dirt on panel, shading should also be considered.

If you check your setup well and match them properly, you might not really need to upgrade now, if it will inconvenience your finances. I can help you out, if you share your panel name plate ratings, your system voltage, and a sketch of your setup.


NB. The 24A harvest you quoted is intanteneous current. In solar setup, we prefer to quote AH, WHr delivered per day.

If you have the money do away with pwm and use mppt, that way you ll enjoy ur money, if u dnt v d cash nw, mk sure u put it in mind that u ll change ur pwm soon, 2kw array is a lot for u to even use pwm.

I can get u epsolar 40amps or 60amps @ affordable price call 08117398294

Explain what you mean by undersized wires, please.

You can visualize this by using a 10,000l water tank filled to the brim with water. If put it on your roof and then connect a pipe with the same diameter of a pencil to it, you are going to have water coming out in trickles (low pressure) at the end of the pipe. By the time the water level in the tank is low, the water pressure will further reduce. If you want the water to come out with sufficient force, you will need to connect a pipe with a wide enough diameter. But even then, when the water level is low, the pressure will reduce.

This is the same way electricity passes through a wire. Charge is the water in the tank, current is the flow of water and pressure at the end of the pipe is the voltage. If your pipe (wire) is undersized (not wide and thick enough) and you have a really big filled up tank at a high enough height (charge), the flow (current) will not just be low but you risk having a leaking pipe (voltage loss) or a burst pipe (fire outbreak).

I hope that helps.

The transformers, the capacitors and everything is more substantial on the FM. Thank you for a job well done

My oga, i don show o,

your recommendation is on point "we should be careful not to sacrifice quality on the alter of low cost
alternatives which do disappoint when needed most"

hi guys long time...

totalgreen!
the man who saw tomorrow!!
you're welcome back.
we all miss you.

all,
my solar water heater is finally up and running.
pictures to follow soon.

Talk to kiekie1. He sourced for my outback mate3 for me. He may have contacts. Cheers

Please how good is Schneider electric xantrex 60amp Mppt?
Someone is offering me one at N130k and an EP 60amp at N150k.
I'm surprised EP is more expensive.

Its your choice ! Ep solar 60a has 2 types ; basically, the more expensive make is the "I TRACER" which i can offer you @145k, while the cheaper "E TRACER" is 135k... Call for PURCHASE !!

The components on the middle one look more rugged. Are you sure you're miskaking capacity (charging current) for quality? What are their respective cost and specifications?

Please gurus, between EP and Schneider xantrex, which mppt is better quality in charge controller?

I wish am a qualified technician. one is coil d other transformer. wot I understand is dat one designed for simple installation should not be used for complex purpose such as dat solar filling station in lagos. if u do, u tink it is not good.

however we should always ensure we get quality. my cracked PV has thought me dat lesson under 2 months of installation & buy from tested& trusted people.

Schneider Xantrex any day. EP Solar is a Chinese knock-off of Morningstar Tristar series, a good one though.

Please house, I need help. I'm now as confused as hell.
Since my two 40/40amps PWMs were harvesting 22amps at peak from the 2kw PC array, I thought that installing a Mppt will help issues.
So off to the electrical mart I went for one.
I got offered a Xantrex (Schneider), a ETracer and Itracer (both EP solar).

On installing the ETracer there was no improvement in harvest, rather a decline in harvest. It did 20amps peak.
So back I took it to the dealer and got a refund.
The Xantrex, based on the poor performance of the EP, I insisted in having it test runned on the 2kw panel setup there. Man! it did 18amps while the PWM that was there harvested 32amps off that same PC array.

Now am confused.
I thought Mppt is far better than a PWM?
What's wrong?
It's a 24v system.

i commend your bold choice going 4 mppt.
don't be discouraged, lucky u it has offered u a real opportunity to gain experience you can't buy off d shelves.

by the way it is too early to determine mppt is harvesting less using 2 to 3hrs. in my view.
1.check if ur cables is rated > 6mm (beta if is 10-16mm awg), if OK then

2. disconnect all ur PV config. if ur running 3x2, load & test each set independently, u will surely notice a set probably from ur last setup down d line drawing you down.

3. consider reviewing the type of ur grounding style.

however, try and draw ur installation so dat masters and gurus can attended to u quickly.
