MPPT charge controller options 4xAGM in Serries

Postby Little Ray » Tue Jan 10, 2017 6:19 pm

Hi,

Looking for MPPT charge controller options.

PV Array
VMP (Maximum Power Point Voltage 110.1 Volts.
Battery Charging Current @ 57.6V 50 Amps.

Battery Bank
4x AGM Batteries in Series.

This system doesn't use or require inverter, the Load is 48v DC direct from the Battery Bank.
So I do not want anything more then an efficient Battery Charger.

Some of the MPPT charge controllers are expensive with features that do not apply to this DC only design.

If you can help with suggestions for Suitable MPPT charge controller, please reply here or by message.

Thanks,
Ray

Hi Ray

I use Two PCM60X charge controller's from MPP Solar
EBay Seller Maximum Solar
Should use a computer to set up the custom settings
They have being running perfectly for almost a year now, vary happy.
57amp is close to there limit though in this heat
I have seen up to 61amps briefly, with 12X250w panels (cold panels after rain best possible conditions)

My first choice was the midnite classic-150 until I found these PCM60X
Keep looking around and compare a few.

Cheers

Thanks Aaron, I have contacted MPP Solar for more detail.

I have been searching and asking questions.
Sunking from Solarpaneltalk is not a big fan of MPP Solar Controllers.

See what we find out.

Thanks.

Ah, Sunking, ask him what he bases his opinion on. I doubt he has had anything to do with the controller you mentioned.

One thing to bear in mind if you go with a cheaper controller from Taiwan or China is the backup service if something does go wrong. You are also taking a risk that the cheaper units will not last as long.

Having said that another option might be the MPPT controllers from the Chinese company EPSolar. In particular the eTracer and iTracer series. I installed an eTracer controller on a friend's off-grid system about three and a half years ago and it is still working well.

Affordable Options I have found:

PCM60X Approx $450 Delivered - Found some talk of problems controlling voltage, I have some concern that any problems would cost me a lot of money. Obviously support is an issue, but more important is the confidence it will do as claimed without damaging Batteries!
MPPSolar - PCM5048 - Time to come out.. :-(
https://forums.energymatters.com.au/solar-wind-gear/topic5457.html

EPSOLAR: What is the difference between iTrace and eTrace?
IT6415ND Approx $550 Delivered
ET6415AD Approx $610 Delivered

Victron BlueSolar 12-48V 150/60 - Approx $770 Delivered
Outback Power FLEXMax 60 - Approx $800 Delivered

I have not made up my mind.
If anyone has genuine input, I am all ears.
If you cannot put it in a couple of lines, your trying to hard.

I have not found any bad reports on EPSOLAR Controllers, price is goods at $550 for iTrace.
What is the difference between iTrace and eTrace?

EPSOLAR:
IT6415ND Approx $550 Delivered
ET6415AD Approx $610 Delivered

With PCM60X or IT6415ND,
Is it theoretically do-able to set AGM Battery bank charging parameters to a Maximum of 59.4V

I do not believe it will be necessary, but handy to know if this is possible and of any negative effect?

Cheers

I sent an Email to MPP Solar regarding PCM60X MPPT Charge Controller and received no reply.

Could be the same for other suppliers, but it doesn't instill confidence for a purchase.

The EPsolar products seem to work well enough, however I've found a couple of flaws in the hardware connections with them which did not require them (out of warranty anyway) to be sent back but did take time to repair which was quite a pest.

MPPsolar I'd be concerned there are enough reports here and there to be very wary indeed.

I'd be using at a minimum the Victron, or Midnite products the Outback Flexmax are good but require extra hardware which you have to buy to manage/monitor them better unless you want to go all Outback of course.

A lot is obvious after you have experience.
The midnight is said to have a noisy fan which could get annoying.

The Victron is a possibility.
I have a couple of general questions:
Has it got fans, if so, are they quite and reliable?
Is it fully programmable with permanent screen?
Any issues, or extras required?

Thanks,
Ray

The fan which is full variable speed in the Midnites have never caused any issue for me at sites I've installed them and my own one, it's not like they are sitting in the bedroom with you and they only run if or when required (5 year warranty) other pluses you can link upto 10 of them together that winds up being a lot of PV and a lot current management able to be accessed monitored and configured via a network, there are soem other really cool features to do with the internet as well..

Victron MPPT charge controller I've only used one it did not have a fan in it.
