❓ Frequently Asked Questions
What is the advantage of using an MPPT controller over a PWM one?
MPPT (Maximum Power Point Tracking) technology increases the charging efficiency by up to 30% compared to PWM controllers by ensuring the solar panels operate at their optimal voltage regardless of battery level.
Can this controller be used with Lithium batteries?
Yes, this series supports various battery types including AGM, GEL, Flooded, and Lithium batteries with customizable charging parameters.
What is the maximum PV input voltage for the 48V models?
The ML4830N15 and ML4860 models support a maximum open-circuit voltage (Voc) of up to 145V, allowing for more flexible panel string configurations.
Does the controller support remote monitoring?
Yes, it features RS232 and RS485 communication interfaces (depending on the model) for data transmission and system monitoring via PC or external modules.
Can I connect multiple controllers in parallel?
The ML4860 model supports up to 16 units in parallel, making it suitable for larger scale solar energy systems.
What safety protections are built-in?
The unit includes comprehensive protection against over-charging, over-discharging, short circuits, PV reverse polarity, and over-temperature.
