[RE-wrenches] MPPT greater than 150V

[Tump]

Sad to say but isn't this the industry norm.... we will have it next month.
 I believe that a HV CC has been in the works for well over 3 years.Welcome
to the world of ever changing solar....kinda like molasses in the winter
time.
we have at least 3 scenarios currently which could benefit from the higher
voltage configuration....
Don't we all..... by the time we might see a HV CC,AC coupling will be the
norm & they will no longer be necessary!

It is my understanding in our pursuit of the apollo high voltage controller
that they have scrapped plans to release that....they said other products in
development have now taken precedence.  It is also my understanding that
MIdnite Solar is still actively developing their high voltage controller
with a potential release this summer.....I have my fingers crossed.....we
have at least 3 scenarios currently which could benefit from the higher
voltage configuration....

Yes, as far as I know.

 

Apollo is supposed to have one in beta evaluation but we haven't been able
to obtain satisfactory information from them how product evaluation is
taking place and when the unit will be available as a product. We had an
application for which we wanted to use this new product and gave up on them
and their product.

Hi there,

 

Can someone confirm that there is still no MPPT regulators available capable
of accepting array voltages greater than 150.

 

Thanks,
