[RE-wrenches] VFXR3648A battery charging

[William Miller]

Friends:



I have a client with one VFXR3648A inverter off-grid with PV and a
generator.  The inverter is set to bulk at 58.2 VDC for 2 hours but when
the generator is required the voltage never gets above 52 VDC.  The PV gets
the voltage up to the 58 volt zone reliable.



The original generator was a portable of about 3 Kw.  I thought it was not
providing enough RMS power so we upgraded to a Kohler vertical shaft 12 kW
air cooled unit.  The problem is still the same:  The bulk voltage of the
batteries never gets above 52 VDC.



On my next visit I plan on resetting the inverter to factory defaults.
Other than that I am not sure what to try.  I have little luck reaching
Outback tech support in the last year so I am hoping someone here can
provide some advice.



Thanks in advance.



William
