MPP SOLAR PIP-8048MAX

Post by dRdoS7 »

Hi,

I noticed that they've added a slightly larger MAX 48V to the range.

https://www.mppsolar.com/v3/pip-max/

Wonder if they have corrected any of the bugs? Or, introduced new ones.

Not sure about the bugs either, but for off grid use and the addition of some separate charge controllers it should do the job well.
This size inverter is better suited to a family home where there could be many appliances running at the same time, not have to bother with load shedding/sharing.
I expect idle consumption to be less than a pair of 4048's in parallel.
Not much known about these MAX series yet.

I can confirm that the main premature float bug is still faithfully and firmly in place. They really believe in that thing.

That's much harder to tell.

On the one hand, any version one product tends to have more bugs. On the other hand, it seems largely a matter of modifying an existing design, mainly just making things bigger, so the chances seem reasonable that it will work much the same as existing models.

This is just so unfortunate, it's not clear why MPP have decided not to fix this. Is there any high Voc hybrid out that that does not have a float bug?

No, no model I know of manufactured by Voltronic Power (so the PIP, Axpert etc models) is free of the bug. Even when the bug is in a completely different place in the firmware, it's always present. It's almost as if it's a corporate policy or something.

I was also looking at this inverter
Since my Clone PIP-MK4850
often goes into ByPass due to overload

Can you explain to me what this float bug is?

Do you know if this model is sold in Europe
with shipping in Italy and by whom
i would not pay too much for shipping and customs
for this i prefer shipping from europe?

This model compared to the MK series working in high voltage
PV side can also work without batteries
and also miscelfare PV and Utility exactly what the MK series
does not do I understand correctly

Thanks

When charging the battery from an intermittent source (e.g. solar on a cloudy day), it misinterprets low charge current as the battery being full. The battery is actually full when two conditions are satisfied: the charge current is low, and the battery voltage is high, near the absorb/bulk voltage setting. They check that it is near the float voltage setting. So what happens is that a third of the way through the charge (say), the battery voltage is near the float voltage, 2/3 of the charge left to go. Along comes a cloud, the battery charge current drops below a threshold, and the inverter says "Oh look! The battery must be full because the charge current is low!". In fact, the charge current is low because there is a cloud, and because of this cloud, it should be charging even longer, not stopping now.

No, I know nothing of availability in Europe. My understanding is that there should be resellers based in Europe, who would have stock in Europe.

Yes, for reasons unclear to me, only the high voltage SCC models can run batteryless.

Sorry, I don't understand this.

Sorry if it's misspelled
I'm Italian and I use google translator

I meant the MAX series can take power
from utility and photovoltaic together?

Example if I have 3000W load and 2000W of photovoltaics
inverter takes 2000W from Fotovotlaico and 1000W from utility
or blend?
because the MK series does not do this at least so I understand
in that case he would use 3000W everything from utility he would use
photovoltaic only if it has equal or lower power than photovoltaic production

Italian reseller: You can purchase MAX from Antonio Bataglia shop. google Primo Axpert MAX 7200-48 cercastock.it

I have this inverter since August. Full review on spanish forum


Conclusion: Plenty of bugs at initial firmware 45.01. Voltronic in 3 months has released many update firmwares to this model. Jump to 45.xx to 90.xx number firmware, so I think they have rebuild full firmware because 45.xx was unstable (F55 error everytime on SBU and SCC on).

On SUB and SCC on, too many active power feed on grid (2kW peak) with 7kWp field solar installed.

Voltronic should improve much more the firmware of this model.

Not Europe, but MPP Solar have a store on Alibaba. For me, in Australia, it works out a bit cheaper (I asked for a shipping quote in Sept.) than buying from the Aust. seller, or from MPP Solar's ebay store. It would take no more than 2 weeks to get here from Taiwan.

Just checked: there is also a 7248MAX that ships from Europe.

Yes, but I do not see the PIP MAX 8048 model available from anyone, perhaps it is too new and we will have to wait a little longer
Only one seller on Ebay has it but it is outside Europe
and too many Customs fees and expensive shipping for me
