MS-PAE (menus 02C-02G) or MSH models only (menus 02C-02I):
• 02C System AC Amps:
AC Load: This meter is the sum of the values from the 02E AC Load Amps menu for each
inverter connected in parallel (i.e., MS-PAE or PE Series). See the 02E AC Load Amps section
for more information on how the AC load amps value is determined.
AC Input: This meter is the sum of the values from the 02F AC Input Amps menu for each
inverter connected in parallel (i.e., MS-PAE or PE Series). This reading is always displayed as
a positive (+) number. See the 02F AC Input Amps section for more information on how the
AC input amps value is determined.
• 02D Inv/Chg Sys Amps (In/Out of Battery): This meter is the sum of the values from
the 02G Inv/Chg AC Amps menu for each inverter connected in parallel (i.e., MS-PAE or PE
Series). See the 02G Inv/Chg AC Amps section for more information on how the inverter and
charger AC amps value is determined.
• 02E AC Load Amps: This meter displays the total AC current delivered to the loads on the
inverter’s AC output terminals. The Load Amps value is positive (+) showing 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: The Load Amps is determined by subtracting the input current value
(02F AC Input Amps) from the current charging the battery (02G Inv/Chg AC Amps).
◊ Inverter Mode example: 0A (input amps) minus – 10A (inverter amps) = 10A (load amps),
see Figure 3-6. A Load Amps 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 as:
AC1 to Neutral = 5A @ 120V AC2 to Neutral = 15A @ 120V
AC1 to AC2 = 2A @ 240V (2A @ 120V + 2A @ 120V)
Load Amps value = sum all 120V currents (5A+15A+2A+2A) = 24A (24A x 120V = 2880W)
◊ When in Standby mode, the Load Amps value is determined by subtracting the input current
value (02F AC Input Amps) from the current charging the battery (02G Inv/Chg AC Amps).
Example: 20A (input amps) minus 10A (charger amps) = 10A (load amps), see Figure 3-7.
A Load Amps display of 10A means 10A x 120V = 1200W load on the inverter.
• 02F AC Input Amps: 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 reading 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 would display 30A.
• 02G Inv/Chg AC Amps: This menu displays the inverter or charger amps and is shown as
an AC value. A negative (–) amps reading indicates the inverter is powering the inverter loads
and the batteries are discharging (inverter amps). A positive (+) amps reading indicates the
inverter is using the AC input source to charge the batteries (charger amps).
