Load Amps (MS-PAE, MS-PE and MSH inverter models only)
: This
meter displays the total AC current delivered to the loads on the inverter’s
AC output terminals. A positive (+)
Load Amps
value indicates power is
being pulled from the inverter to run an AC load—either using the batteries
in Inverter mode, or from the AC input source in Standby mode.
When I look at the Loads Amps display on a remote, how is this value
calculated?
For MSH Series inverters:
Load Amps
is determined by subtracting the input
current value (
02C
Input Amps
) from the current charging the battery (
02D
Inv/Chg Amps
).
◊
Invert mode example: 0A (input amps) minus -10A (inverter amps) =
10A (load amps), see Figure 3-6. A load amps value of 10A means 10A
x 120V = 1200W load on the inverter.
◊
Standby mode example: 20A (input amps) minus 10A (charger amps) =
10A (load amps), see Figure 3-7. A load amps of 10A means 10A x 120V
= 1200W load on the inverter.
◊
Load Support mode example: 10A (input amps) minus -10A (inverter
amps) = 20A (load amps), see Figure 3-8. A load amps of 20A means
20A x 120V = 2400W load on the inverter.
For MS-PAE and MS-PE Series inverters: The
Load Amps
value is shown as
120VAC current, even though there may be 240VAC loads, and is calculated
differently based on the mode.
◊
When in Inverter mode, the
Load Amps
value is the sum of all the 120V
currents from both HOT 1 and HOT 2 outputs.
Example: If I have a 5A @ 120V load on the HOT 1 output, a 15A @ 120V
load on the HOT 2 output, and a 2A @ 240V load on the HOT 1 and HOT
2 outputs; what would the
Load Amps
menu display? The display shows
24A, which is the 120V equivalent current.
Calculated:
AC1 to Neutral = 5A @ 120V
AC2 to Neutral = 15A @ 120V
AC1 to AC2 = 2A @ 240V (2A @ 120V + 2A @ 120V)
Load Amps
value = add all 120V currents (5A+15A+2A+2A=24A), then,
multiply sum by 120V load (24A x 120V = 2880W).
◊
When in Standby mode, the
Load Amps
value is determined by subtract-
ing the input current value (
02C
Input Amps
) from the current charging
the battery (02D Inv/Chg Amps).
Example: 20A (input amps) minus 10A (charger amps) = 10A (load
amps). A
Load Amps
display of 10A means 10A x 120V = 1200W load
on the inverter.
Input Amps (MS-PAE, MS-PE and MSH inverter models only)
: This meter
displays the total AC amps being used by the inverter for charging and for
any load connected to the output of the inverter. This meter value is always
displayed as a positive (+) number.
Example: If the charger is delivering 20A to the battery from the AC source
and the load connected to the inverter output is using another 10A, the
combined load on the incoming AC source is 30A. So the
Input Amps
display
would show 30A.
