3.0 Setup
Info:
The Inverter will automatically begin inverting when the DC
voltage increases to
≥
12.5 VDC (12-volt models),
≥
25.0 VDC
(24-volt models), or
≥
50.0 VDC (48-volt models). If AC power
is available and connected to the inverter’s input, the inverter will
automatically clear the ‘Low Battery’ fault, pass the input AC power
to the output, and begin charging the batteries.
Where should I set the LBCO setting?
If you want to cycle the batteries
slightly - but don’t want to discharge them more than 20%*, then the
LBCO setting should be set from 11.5 to 12.2 VDC (12-volt models), 23.0
to 24.4 VDC (24-volt models), or 46.0 to 48.8 (48-volt models). In some
applications, such as those installed in an off-grid home or when doing a lot
of dry-camping in your RV, you may want to cycle down to 50%* by setting
the LBCO from 10.0 to 11.4 VDC (12-volt models), 20.0 to 22.8 VDC (24-volt
models) or 40.0 to 45.6 VDC (48-volt models). In extreme circumstances,
you have the ability to discharge the batteries to 80%* by setting the LBCO
to 9.0 or 9.5 VDC (12-volt models), 18.0 or 19.0 VDC (24-volt models), or
36.0 or 38.0 VDC (48-volt models) before recharging.
* These discharge percentages are rough estimates; for accurate battery
monitoring, a battery monitor such as Magnum’s ME-BMK is required.
Info:
The higher the LBCO setting, the less the inverter will discharge
the batteries; which should allow the batteries to have a longer life.
The down side to a higher LBCO setting is that you need to charge
more often to prevent the inverter from shutting off in fault mode.
Info:
If there is an ME-AGS-N installed, it should be set to start
≥
1.0
volts higher than the LBCO setting – this is to prevent the inverter
from shutting down before the generator comes on.
02C AC In-Time -
This feature allows you to connect to the local power
utility at a predetermined time of day. When the current time falls within
the set times, the inverter/charger connects to the AC connected to the AC
input terminals. Once time passes outside the set times, the inverter/charger
disconnects from the AC source. If your local power utility offers “time of day
billing” this feature may save you money by only connecting to the utility
when rates are the least expensive.
Default Setting:
6:00A - 6:00P
What is the “AC In-Time feature”?
This feature allows the incoming AC
to connect to the inverter/charger and charge the batteries only during the
time of day set in the 02C AC In-Time menu. Even if AC is present on the AC
input terminals of the inverter/charger it will only connect during those times
that were previously set up.
