3. Product Features
Thank you for choosing Armada products! This MPPT solar charge controller is a device for solar charge regulation and
direct current output load control. This device is mainly used in small and medium sized off-grid solar power systems.
These MPPT charge controllers have features as follows:
•By continuously checking solar panel power output changes, the controllers utilizes multiple MPPT charge
algorithms in combination to boost charging efficiency in different weather and temperature conditions.
•Built-in buffer, allows for exceeding rated power input by 25%.
•Charging modes available for most common deep-cycle battery types in the market, including AGM (sealed lead acid
batteries), GEL, Flooded, and Lithium.
•Allows mobile phone APP operation for monitoring and parameters settings, with connection of inbuilt or external
bluetooth communication module (optional accessory, not in the standard package list).
•Auto recognition of 12V/24V battery system voltage by ARC20-MPPT, ARC30-MPPT, ARC40-MPPT model; auto
recognition of 12V/24V/36V/48V battery system voltage by ARC60-MPPT model. Lithium battery excluded from this
feature.
•Supports recording of system running data including power generated and power utilized for up to 300 days,
compatible with monitoring App through IOS and Android.
•Provides multiple load control mode options for light based, time based and manually adjusted scenarios. Low
no-load loss.
•Industrial grade design with reverse polarity protection for solar panels, battery and load.

Controller Specification
The variable “n” is adopted as a multiplying factor when calculating parameter voltages, the rule for “n” is listed as: if
battery system voltage is 12V, n=1; 24V, n=2; 36V, n=3; 48V, n=4.
For example, the equalize charge voltage for a 12V FLD (Flooded) battery bank is 14.8V*1=14.8V. The equalizing charge
voltage for a 24V FLD (Flooded) battery bank is 14.8V*2=29.6V.
