Hi all, question: How do i reduce the max PV voltage?
I have a ESS system running with a Multiplus 48/5000 and 48/100AH Lifepo4 battery,
the battery will upgraded to 280AH in the near future.
Parallel to the system i have an 3000W AC inverter (about 3600Wp on roof).
I would like to swap out the AC inverter for the MPPT RS 450/100.
Problem is, a couple times a year the voltage peak from the PV is about 465/470V!
I know this because i had an Chinees offgrid inverter for a year and got a couple alarms above the 450V mark. Like i said, only a couple of time but i know the 450V is a hard limit for the MPPT RS.
Besides disconnecting 1 PV panel (all in serries) to get the voltage down,
is there another way to control this peak voltage or "transform" it down somehow?
A device i do not know of?
I rather not dissconnect 1 PV panel as i live in a rental house,
altought i doubt new people will notice that in the future hahaha..
If the MPPT RS is not an option i might opt for a FRONIUS PRIMO on the AC 1 out of the Multi,
that way the high voltage would not be a problem.
Thanks for your advise on this!
Steve.
