01
AC output source priority:
Configure the priority of
which power sources supply
the AC output load
Utility / AC input first (Default)
“USB” for:
Utility → Solar → Battery
AC input / utility will provide power
to the loads as first priority. If there
is excess solar power beyond what
is required for battery charging,
this power is used to supply power
to the loads instead. The battery is
not discharged (Grid mode).
Solar and battery will provide
power to the loads when AC input /
utility power is unavailable (Off-
Grid mode).
Solar / PV first
“SUB” for:
Solar → Utility → Battery
Solar provides power to the loads
as first priority. If solar power is not
sufficient to power all connected
loads, AC input / utility power will
supply the loads simultaneously
(Grid mode).
If no solar power is available (ex. at
night), AC input / utility power is
used exclusively. The battery is only
discharged when the AC input /
utility power is unavailable (Off-
Grid mode).
SBU priority
“SBU” for:
Solar → Battery → Utility
Solar powers the loads as first
priority. If solar power is not
sufficient to power all connected
loads, the battery will supply power
to the loads at the same time. The
Any-Grid is disconnected from the
grid at this time (Off-Grid mode).
AC input / utility provides power to
the loads (Grid mode) only when
the battery voltage drops to either
low-level warning voltage or the
setting point in settings menu 12.
When first applying SBU priority, it
may take up to 10 minutes for the
Any-Grid to switch to Off-Grid
mode.
02
Maximum total battery
charging current of AC and
solar charging combined:
Max. total charging current =
AC input charging current +
solar charging current
This setting is important to
limit charging current for
some battery types.
10A
80A (Default)
Can be set from 10 ~ 80 Adc (up to 120 Adc for PSW-H-6.5KW-120/48V)
in 10 Adc increments. This is the battery-side DC charging current.
03
AC input voltage range
Appliances
Accepted AC input voltage range
from 90 ~ 280 Vac for 230 Vac
models, 80 ~ 140 Vac for 120 Vac
models.
