Why Choose an MPPT Charge Controller?
MPPT, or Maximum Power Point Tracking, technology continuously adjusts the operating point of the solar panel to collect as much available power as possible.
Compared with a standard PWM controller, an MPPT charge controller can provide improved charging performance during cold weather, low-light conditions, and when using higher-voltage solar panels. This helps make better use of available solar energy and can reduce battery charging time.
Battery Compatibility
The Armada ARC-MC2420 can be configured for several common battery types:
- AGM batteries
- Flooded lead-acid batteries
- Gel batteries
- LiFePO4 lithium batteries
- User-defined charging profiles
Always confirm the battery manufacturer’s recommended charging settings before selecting or programming the battery profile.
