To at least partially answer Ray's question about Class-R fuses: Square-D
Heavy Duty fused disconnects, commonly used as DC discos for PV arrays and
which use Class-R fuses, are only rated for 80% duty. The non-fused HD
discos are 100% rated in PV systems. I'm not sure if that is because of
the fus

According to the service manual I have;
d-29 = "Fan Lock"
Cause: fan is locked
Cause: fan has failed
Action: Replace
Fan part#: 95KPZZ1036ZZ

Most combiner boxes, DC rated breakers, and DC rated fuses and fuse
holders we use today, qualify as assemblies for the 100% exception
(Outback, Midnite, etc.) so you only have to size the OCP by 125% of
short circuit current rating for edge of cloud effects.

Thanks Chris,
It's one of those great things about the solar industry that there is
always more stuff going on than one man can keep track of:

Friends:
I have a new client with some very old inverters. I know nothing about the
Sharp inverters. This person is on a fixed income and I am trying to help
her out on the cheap.
I read a D-29 error. My research indicates this is a fan error. Is this
correct?
Can this be repaired in
Mark,
The term "recombiner" to me is an electrical panel used on the AC output of
multiple inverters to combine their electrical outputs.
That is different to a "combiner" which connects solar strings through
fuses to a busbar for connection to the inverter using one conductor pair.
In grid tied s
