Should I wire the panels in series or parallel using MPPT charge controller?
The panels can be wired either in series or parallel or combination of series/parallel using MPPT charge controller.
-
Can I connect an inverter to the load terminal?
The load terminal is only compatible to run one small 12 V DC load with low amp consumption. other devices and appliance with surge and high amp draw should be connected directly to the battery.
-
Can I change/adjust the charging parameters on MPPT charge controllers?
MPPT charge controllers offer a USER setting, this USER setting will allow you to program your own charging parameters, such as Boost voltage and Float voltage.
-
Can I cover or mount the charge controller in an enclosed box?
The Charge controller will convert the excess voltage into heat and dissipate into air. Therefore, it should be mounted in a well-ventilated area with 9-Inch clearance around the charge controller.

How to choose the perfect charge controller for my solar system?
PWM vs MPPT: Pulse width modulation (PWM) and maximum power point tracking (MPPT) are the two types of charge controllers that are most frequently used in solar power systems. Both modify charging speed to allow charging closer to the battery's maximum capacity and monitor battery temperature to prevent overheating.
The choice of charge controllers depends on the size of the solar energy system. PWM controllers can deliver adequate performance in small solar systems. In such projects, efficiency might not be the biggest concern. But how well the charge controllers perform matters a lot in large projects. For example, in a 1kW solar system, you would need an MPPT solar charge controller.

MPPT vs PWM: Which solar charge controllers are better?
MPPT devices are more efficient. MPPT charge control devices have 30 % more efficient in charge efficiency according to PWM type. Panel voltage and battery voltage should be matched in PWM systems. In MPPT systems, the panel series are allowed to have higher voltage than batteries. This means more flexibility for system growth. However, MPPT controllers are more expensive than PWM controllers. Because of that, the PWM is a good low-cost option for smaller systems where the efficiency of the system is not critical, e.g trickle charging. But for solar systems with a maximum power output of up to 1kW, MPPT solar charge controller is the clear choice.
