• 02D AC In – Volts DC:
Based on the inverter’s battery voltage, the
AC In – Volts DC
settings
determine when the inverter automatically connects and disconnects the incoming utility
power.
◊
Connect
– This setting determines at what DC voltage the inverter/charger connects to
incoming AC and transfers the loads from the inverter battery power to the utility grid. The
transfer occurs only if the battery voltage remains below this setting for 10 seconds.
Default settings:
11.0 VDC
(12v),
22.0 VDC
(24v),
44.0 VDC
(48v)
Ranges:
9.0-15.9 VDC
(12v)
, 18.0-31.8 VDC
(24v)
, 36.0-63.6 VDC
(48v)
◊
Disconnect
– Once the inverter has connected to the incoming AC—based on the VDC
Connect
setting—this setting determines at what DC voltage the inverter/charger disconnects
from incoming AC and resumes powering the AC loads from the inverter’s battery power.
Default settings:
14.1 VDC
(12v),
28.2 VDC
(24v),
56.4 VDC
(48v)
Ranges:
9.1-16.0 VDC
(12v)
, 18.2-32.0 VDC
(24v)
, 36.4-64.0 VDC
(48v)
Info:
The
02D AC In – Volts DC (Connect and Disconnect)
settings are not temperature-
compensated.
Info:
If you have a ME-BMK battery monitor, use the
AC In – SOC
feature instead of the
02D AC In – Volts DC
feature. The
AC In – SOC
feature takes temperature compensation
into account and is a more accurate way to identify when your battery is discharged/
charged—to determine when to transfer to/from utility power.
What is the AC In Volts DC feature?
This feature allows the inverter system to automatically
switch between utility connected and standalone battery operation—based on the VDC voltage
(i.e., battery) to the inverter. When using this feature, the inverter loads are powered from the
battery—which is normally charged from an energy source such as solar, wind, and/or hydro.
In the event the energy source cannot keep the battery voltage from falling, once the battery
voltage drops to the
Connect
volts
setting the inverter connects to the utility to continue powering
the loads connected to the inverter’s output (and to charge the battery). When the energy source
can again deliver enough power to raise the battery voltage to the
Disconnect
volts setting, the
inverter disconnects from the utility and again powers the inverter loads from the battery.
Where should I set AC In – Volts DC?
Check with your battery manufacturer to determine
the correct settings for your batteries. Typically, battery manufacturers do not recommend
discharging the batteries below 50%, which when related to a voltage setting is approximately
12.0-12.2 VDC, 24.0-24.4 VDC and 48-48.8 VDC for 12, 24 and 48-volt batteries, respectively.
In order to protect the batteries from over-discharging, set the connect voltage setting to 12.2
VDC, 24.4 VDC, or 48.8 VDC, respectively.
Set the disconnect voltage setting higher than the absorb voltage setting in order to reduce
cycling of the system. A setting higher than the absorb voltage requires the energy source (e.g.,
solar, wind, etc.,) to raise the DC voltage above the charger settings. This ensures the battery
gets at least an 80-85% charge (preferably 100%) before the AC is disconnected and the inverter
resumes powering from the batteries.
• 02E AC In – SOC:
This setting determines when the inverter automatically connects and
disconnects the incoming utility power based on the SOC of the inverter battery bank.
Note:
Requires a ME-BMK battery monitor to provide SOC values to the inverter.
◊
Connect
– This setting determines at what battery SOC% the inverter connects to incoming
utility power and transfers the loads from the inverter battery power to the utility grid.
Default setting:
80% SOC
Range:
20-99%
◊
Disconnect
– Once the inverter has connected to incoming AC—based on the SOC
Connect
setting—this setting determines the battery SOC% at which the inverter disconnects from
incoming utility power and resumes powering the loads from the inverter’s battery power.
Default setting:
100% SOC
Range:
21-100%
