Setup
• 02B Load Amps (MS-PAE, MS-PE and MSH 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 subtracting 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.
• 02C Input Amps (MS-PAE, MS-PE and MSH 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.
• 02D Inv/Chg Amps (MS-PAE, MS-PE and MSH models only) – 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).
• 02E Input AC1 (MSH models only) – This menu displays the RMS value of the AC voltage
at the inverter’s AC1 and NEUTRAL input terminals.
• 02F Input AC2 (MSH-RE models only) – This menu displays the RMS value of the AC
voltage at the inverter’s AC2 and NEUTRAL input terminals.
Info: If the 02F Input AC2 menu displays voltage (~ 50v), but the generator is off or
nothing is connected to the AC2 input, the AC2 neutral-to-ground bond connection is
not correct or not connected.
