Chg Bad AC Qlty In Charger or Bypass mode the
PROsine is being powered from an
incompatible AC source, probably a
very low quality generator. The
PROsine is compatible with virtually all
nominal 120V 60Hz AC sources
(including Modified Sine Wave) but it
is possible that a very low quality
source may cause a problem in some
operating conditions. If these errors
occur the PROsine will disconnect from
the AC source because it is unsafe to
continue to operate the PROsine from
that source - and it may cause problems
for some AC loads as well.
Test the PROsine with a good quality generator
or the AC utility to verify whether the normal
generator is the problem. If so, enabling charge
mode and turning on a DC load (e.g. a light)
should allow the PROsine to operate correctly
from any generator which is not defective. If it is
a small generator and is unable to supply all the
current the PROsine might demand, the AC
Breaker Size rating in the Configure PROsine
— Basic Menu can be lowered so as not to
overload the generator.
