• MONITORING

• The ARM-MS/MSX series is very similar to the ARM-HS series inverter-charger, except that it offers a built-in MPPT 25A or 60A solar charger and is currently available only in 24v or 48v models (800w, 1.6kw, 2.4kw, 3.2kw, and 4.0kw). The MPPT solar charger are rated for 600w (for 25amp) and 3000w (for 60amp) respectively. The MS/MSX 48v series also features a dual source charging capability (AC + Solar) and the max charging current from both sources are up to 120A.
  ARM-MS/MSX features a wide input range support from 90~280VAC (Appliance Mode) and 170~280V (UPS Mode). This is especially important and useful for areas with unstable grid power supply. Similar to our other series of solar inverter-charger, ARM-MS/MSX also offers AC or DC (solar) priority modes, and the controls can be easily modified from LCD menu that offers comprehensive system information. It also comes with a USB port* that can be connected to a PC for system monitoring. When selected to operate in DC (solar) priority mode, inverter will increase charging current from Solar source whenever possible, while reducing current from utility sources.
  ARM-MS now features a “stackable” or “parallel” version (48vdc models only) which allows users to expand output of an inverter system by integrating the output circuits of each individual unit. Maximum parallel number of units is 6, so users can configure a parallel system either as:
  • Single phase output up to 24kw using 6 units, OR
  • Three phase output using either 3 units (12kw) or max 6 units (24kw)

   

  ARM-MSX is a special model which features the upgrade of internal MPPT charger from 25A to 60A. This currently applies only to 1.6kw and 2.4kw model.

  When using generators as AC input....

  
  1. Genset starter feature will send a signal to generator to act as backup when conditions are met. Generators with standby/remote start capability is required – please check with your generator manufacturer on compatibility.

  2. Inverter-generator is recommended due to its cleaner output than conventional generators.  Unsuitable generator output may be rejected by the inverter.
