MPP SOLAR PIP-8048MAX

Post by dRdoS7 »

Hi,

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

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.
