3.0 Setup
Info:
The inverter automatically begins 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/ME-BMK-NS 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 that is 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 as 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.
Should I use the AC In-Time feature?
The most common use of AC In-
Time is when your local utility company offers peak rate savings. Peak rate
savings are when the utility company offers a lower rate per kWh (kilo Watt
hour) on your power bill, usually at night when there is less demand on the
local utility grid.
Where should I set AC In-Time?
Check with your local utility company or
installer and see if they offer lower rates at particular times of the day. If a
lower rate is offered, try setting your connect time to coincide with the utility
companies lower rates, this will save you money.
