1. How to recognize a real MPPT solar controller?
a. MPPT solar controller is with inductance core.
b. Digital integrated circuit design make MPPT solar controller with range PV input voltage range and auto recognition the voltage of system (12V, 24V, 48V)
c. For MPPT solar controller, the input voltage is higher than output voltage; input current is lower than output current. But for PWM solar controller, the input voltage is the same as output voltage; input current is the same as output current.
d. MPPT solar controller (95-99%) is higher efficiency than PWM solar controller (60-70%).
e. MPPT solar controller is with three stage charging mode (CC, CV, CF), which can prolong the battery life-span 1-2 years. PWM solar controller most is with CC or CV charging mode, which can’t protect battery very well.
2. Controller can be suitable for 12V, 24V, 36Vand 48V system. Which system is most beneficial for customers?
48V system is the best choice. Because the loss power is in proportion to the current (P=I2*R). In order to decrease the current value, increase the system voltage is the best choice.
Some customers may think lower current will influence the charging speed. Actually, this is a misunderstand. The charging speed depends on the output power of the controller. It means choosing the highest voltage system is most beneficial for customers.
3. “Why MPPT controller charging current or charging voltage is lower than PWM controller?” Some customers asked
As we know that MPPT controller is with three stage charging mode: fast charge, constant charge and floating charge. But PWM controller only has one charging mode: fast charge.
On the fast charge mode, controller will use the highest voltage or current to charge the battery (in the battery bear range), when battery capacity reaches to 80%, MPPT controller will change to constant charge mode. When battery capacity reaches to 100%, MPPT controller will use floating charge mode. In constant charge and float charge modes, the MPPT controller charging current or voltage may lower than the PWM controller. In these two modes, MPPT controller put more attention to protect the battery. That’s why MPPT controller can prolong the battery life-span.
4. What is voltage of the DC load?
The DC load voltage is the same as system voltage. If system voltage is 12V, the DC load voltage is also 12V.
And the DC load port can bear within 40A DC loads.
5. How many MPPT controllers can be in parallel?
The same model MPPT controllers can be in parallel without quantity limitation.
