For those who are abandoned by their SAV service or are no longer under warranty, I give you the latest firmware that Mppsolar gave me. but if you have to install this update, you have to check that you have the new connection of the probe (from 20190315) Well remember that if you make these updates, you lose the warranty. So I repeat if you have a problem, contact your SAV service first. MPI5.5KW Update 20200130.zip

But MPPsolar's after-sales service has been top-notch. In 2 weeks, I received a new card (for 50€ + customs taxes but it doesn't matter) which had for only difference the modification of the probe connection.

the SAV had provided me the infiniteE5.5KW Update190522 which did not prevent the 5KP54A diodes from exploding. I think that he forgot to inform me that they had modified (notice of 2019-03-15) the connection of the temperature sensor. Thermal sensor cable change on the MPI5.5Kw 20190315.docx

After several months of use, I can say that my inverter is now working perfectly. for information my Mpi 5.5kw was out of order because of a problem of load voltage at more than 60v. this is a design problem because if you set the charge to more than 60V, the 5KP54A diodes heat up and explode as soon as the charge goes into "Floating" mode. the notice is false, this equipment is not able to charge at 63V. at home, I charge my PbCa batteries to 58.6V maximum and no more problems.

yes ,Mpp solar ma provided the files ( infiniE5.5KW Update190522 ) for the update. you must be patient, because despite this patch, there are still problems. I too am waiting for answers from customer service. if you're left alone without a solution and when all is fixed at my place I'll help you.

Bonjour a toi bgrkovic yes, there is an update that fixes the problem in ON mode but not for stand-by mode...the update changes the "Main CPU to 00000.34 and the Secondary CPU to 00000.38". but first, contact customer service.
