Hi,

I have 3xPIP-4048MS with 5400W PV and I am adding 5500W more...

Does anyone know is it possible to "return" excess power, when batteries are full, to grid (power company) with PIPs or I have to buy new 10kW grid inverter to do that?

All suggestions are welcome :)

Thank You.

My understanding is that the models that can operate without a battery (so that excludes yours) can in some modes push power from PV to AC-out, but I suspect that they aim not to export anything.

So that's a no, unfortunately.

Hey all,

I have an option to go with a 64V inverter which I'd like as my current 5kw with 74.30 does not support patched firmware as yet, but based on the clipping issue at lower voltages I know this is not ideal.

Which is better, the 64V with patched firmware or the unpatched version I have now? If a patch will come out at some point I'd rather wait with my non 64V.

Thanks in advance,

Gareth

Patched firmware 74.40e is now in early alpha testing (eyeballing the code). Depending on my time, it should be available for beta testing in the next week or so.

That's amazing news, thank you. Crazy that our purchase decisions are made by enthusiasts that fix factory issues... You guys are rock stars.

@mojo Please post photos of the labels on the sides of the two inverters. Block out the rightmost 6 digits of the serial numbers if you wish.

Hi, sorry for the late reply, was away for a week at the time. Here are the labels, your knowledgeable advice will be appreciated.

Ah. One is a ...5P64 and the other is a ...5P. That means a different turns ratio for the transformer, and a different range for all the battery voltage related parameters. So the CAN packets will be different and incompatible. It will not be possible to parallel them.

It looks like your ...5P64 was bought recently, as it was manufactured in September 2019. Would it be possible to return it for a SOL-I-AX-5P (without the 64 at the end)? I think that the suppliers and/or the manufacturer see the 64 V models as superseding the 58.4 V models, but really they're just a different set of compromises. Sadly, it's possible that even if your supplier is willing to do the swap (perhaps with a generous payment to cover shipping), because of this superseding mentality it might be difficult for your supplier (presumably Mecer) to obtain a non-64 V model.

Hi,

Could it be connected in parallel with my 3 existing 4048MS?

I did not find 4048V model on ebay? Do you have some link to it?

Could You please give some more info?

Do you know if 5048MK can export to grid?

Thank You and best regards

The V series are hybrids, not off-grid models, so it's no surprise that they can export to the grid. [ Edit: However, they look more like the off-grid models, and may be based on off-grid hardware. That's speculation on my part. ]
Do you know if 5048MK can export to grid?
The MK (Axpert King) is a 145 V MPPT max model, meaning that it can't export to the grid. It's also the only dual conversion model, and it appears that the converter between the AC-in and battery is never run in reverse. It quite possibly is designed to be unable to do this. It's not clear whether it's possible to operate the inverter proper when the unit is in bypass mode (note: on this model, bypass mode and line mode are very different). In bypass mode, AC-in is connected to AC-out, and the inverter output is connected to AC-out (and hence to AC-in). If such operation is possible, then there would be a path for energy to flow from the PV-in to AC-in, i.e. to the grid. However, none of the operating modes in the manual show this happening.

Actual PIP-5048MK owners may be able to add real-world experience to my theory.

Hello all it's been a little while since I posted last hope you've all been well. I'm just curious if any of you have used the ICC APM software to switch on a control relay wired into the inverter switch (at the bottom) that switches on/off the slave inverters. And will switch more back on based on power demands etc in the house all programmed through apm.

Can any of you foresee any issues?

Cheers.

The 100th inverter installed.


Thanks to your help I could manage some problems occurred.(Error 90, fan problems, firmware compatibility, etc, etc.)

? But the one shown in the Ebay advertisement is a V2. Perhaps he/you meant that the V are now at end-of-life, and the V2 are replacing them. But the V2 are 450 V max MPPT models, so you'd need to add insulation monitoring to be legal in Australia.

I have no idea about the regulations in Croatia. Being a grid-tie capable inverter, they could well require type approval as well; they do in Australia.

My bad... V is EOL, not V2. :roll:

Yes I have asked them again and the seller said that they have CE certificate and do not have EU regional certificates so they do not import it into the EU. :x

All opto-couplers seem to deteriorate slightly with age, so if it was marginal then, it could well be unable to handle a firmware update now. Ordinary communications (commands and responses other than firmware updates) operate at 2400 bps, where there is four times the time for the opto-coupler output to settle at the correct level.

Hi friends.
Yesterday I replaced the opto-couplers of communication board as suggested by Coulomb and yes, now it works fine.
