U3 is the second mppt charger processor. No remote display. Yes 2 solar panel icons. Also you can read each arrays voltage and power seperately and total power. Very nice unit.

Assume it is a bigger case? Is it possible to mod a pip to add a second cc?

Yes, it is a slightly deeper case.

I very much doubt it. The fact that the SCC version numbers go to 01 00 suggests to me that they may be using a different microcontroller now.

And the killer: the existing LCD display doesn't have the two solar panel icons, and I doubt you could replace it. Game over! Image

It might be possible to incorporate an external SCC [ Edit: integrated with the main PIP's settings ], but it would require severely modified firmware.

Mpp have a seperate mppt solar charge controller. The problem I used to have with the 4048ms was that it did not generate enough solar power, especially for sites with no generator or mains. My previous solution was to parallel pips or add a solar charge controller. Msd model solves that problem better.

"The problem I used to have with the 4048ms was that it did not generate enough solar power"

Yes I have to agree I could only get a steady 62amps from one but this was not enough for the 1100Ah battery with also supplying the load
Now I have had up to 97amps with the two units which works out ok.

I think a stock 4048 is a reasonable package. All things considered in the small box for the price. Anyone with a larger demand is going to want two of them anyhow.

Small cabin, mobile home, weekender 3000w of PV and 4000w continuous AC is perfect. Particularly if your using lithium batterys that make much better use of that 3000w.

A modern family home with mod cons 6000w of pv and 8000w continuous Ac is about perfect.

Trying to stuff two much PV charge potential into the box with the inverter just isn't always the best outcome.

Is anybody know difference between this two models
pip4048ms
vs
MUST PV18-5KMPK
What is better on your opinion?
Are software and firmware compatible from pip4048ms with MUST PV18-5KMPK?

MUST is a fake replica of Voltronic/MPP Solar product. I will not suggest you to buy their product. Go for PIP4048MS!

Indeed. MPP solar (who are a re-brand the real thing) have a short page on this:

This is not known at this stage. My guess is that the Must (and they use other brand namess; see my edit in the previous post) are true knock-offs. There is a *lot* of work needed to develop, test, and refine the firmware in these inverters; I know because I've studied it for months, and still don't know the function of many parts of it. So I'd say that they would have copied the firmware as well; perhaps changing any copyright notice (I don't remember any) or other identifying characteristics. I remember the Taiwanese IBM clone manufacturers back in the 1980s (?) were adept at this. Now the tables have turned, it seems, as a Taiwanese designer (Voltronic) appear to have been copied by a Chinese manufacturer.

So if you end up with one of these somehow, it seems likely that Voltronic firmware (original or patched) would work. But that's far from guaranteed; it's possible that Must designed a product from scratch that merely looks like the PIP-4048.

I have a question regarding MS4048 in parallel.
In the Instruction Guide is like that:AC output mode
*This setting is only available when the inverter is in standby mode (Switch off).

But, on the other hand the say
Step 2: Turn on each unit and set “PAL” in LCD setting program 28 of each unit. And then shut down all units.
NOTE: It’s necessary to turn off switch when setting LCD program. Otherwise, the setting can not be programmed.

So, to set the menu 28 in PAL mode, the inverter must be turned on or off?

The firmware prevents you from changing setting 28 when the switch is on. So you need another way of powering the processor.

I believe that the recommended way is to turn on the AC to one unit *only*, ensuring that the inverter switches are off for *all* inverters, then you can change parameter/setting/config item 28 to PAL or whatever is needed. Then turn off AC to that inverter, and repeat for all the others. Obviously, you'll need separate breakers or isolators for each inverter that is paralleled, but I think that would always be the case. If not (this would be a very unusual installation), you could use solar power.

Someone is having a winge on the Whirlpool forums about Giant Power's warranty terms. Looks like GP changed the warranty conditions online after a customer returned one with corrosion.

Wayback time machine doesn't lie.

Disgraceful behaviour if that's the case. So much for local support....

Some people are just never happy and will find some way to point the finger at every product they own.

My unit is running in the hinterland where if it's not raining its just finished raining or is about to rain and enough moist air to fill a hungry hippo with about 1/2 Lt of water In a few days.

No issues with corrosion on my unit.

They do offer a option to have a extra coating over the boards for Marine applications. Though stock I would say it's no worse than many other inverters. It's not designed to be mounted to a fence post in a padoc. Under cover and kept running - warm dryish I don't see issues.

Quick question which I hope can be answered. Can the PIP4048 (Axpert MKS Plus 5kva with single MPPT) be paralleled with the newer Duo and Trio Models.

I have 4048 5kva and want to add a MKS Plus Duo/Tri for extra power and more MPPT options...but in parallel.

Thanks
Mark

I think that will depend on whether they need matching firmware or not. Since the Duo and Tri models seem to have different firmware to the single SCC models, my guess would be no. But it's only a guess.

Edit: I'm glad to be wrong. I just happened to notice this:

"Customers who have purchased the 48v MS series will also be able to parallel with the 48v models of the MSD/MST series, though firmware updates may be necessary."

[Edit: They now say "MSD/MST also retains the ability to support parallel operation and will work only with the same model name.".]

It seems that there is a series of models with slightly higher DC limits, e.g. the PIP-4048MSE:

http://www.mppsolar.com/v3/pip-hsemse-series/

They seem to allow up to 61 V for the float or bulk setting, and a 63 V limit on the DC bus (presumably, if something else is charging it). They also seem to have an updated look, and may be more compact.

Edit: they suggest that some features are missing, and these are "economy" models. So compare features carefully.

The answer is "Yes". As you can read on the PIP-MSD/MST webpage:

"Customers who have purchased the 48v MS series will also be able to parallel with the 48v models of the MSD/MST series, though firmware updates may be necessary."

The Perl script runs on a RasberryPi
it written to be automatic i.e.;

auto switches to battery \ Utility mode for peak/offpeak times

reads in next days weather forecast < when running from batts at night, voltage level based on next days weather i.e. if you know its gonna be sunny and get a good charge, why not use more battery or less if its gonna rain etc

reads in solar output from a grid connected solar system < to auto increase/decrease utility charging current

see graph - red line is power usage by the mppsolar unit..and power from house but instead of feeding into grid mppsolar uses up to charge batts etc

That's beautiful work John. Are you making it available to others? Is it free of charge? Is it open source?
