Maximum number of PV module

LAST EDITED ON May-30-04 AT 08:38 AM (EST)

Knowing that the Sharp 175W-R5EIU has;
Isc of 5.55
Ipm of 4.95
also that the Outback MX 60 has;
a maximum Isc input of 48
and a maximum Ipm output of 70,
am I correct that the maximum number of Sharp 175W-R5EIU PV modules wired to an Outback MX 60 charge controller is
8 If they are wired parallel for 24 volts,
14 wired series/parallel for 48 volts?
If ether of these two configurations were charging a 12 volt nominal battery bank, would this affect the maximum Ipm output of the MX 60?

Re: Maximum number of PV module

The MX60 is good for about 60 amps out to the battery.
If you have a 24 volt battery system, then about 1600 watts worth of panels is what you can connect to it.  3200 watts or so for a 48 volt battery system.  So, if you have 175 watt panels, you could connect up 1600W / 175W or 9 panels max for a 24 volt battery or 18 175 watt panels if it is a 48 volt battery system.
