MPPT Controllers

In this collection, we have collected various kinds of MPPT solar charge controllers. There are some factors you need to take into consideration, just like battery voltage range, operating temperature range (heat dissipation), monitoring, build quality, MPPT tracking speed, real-world performance, price and so on. Here, you would always find that the high quality and affordable.

More about MPPT Controllers

What is MPPT Solar Charge Controller?

The MPPT (Maximum Power Point Tracking) charge controller optimizes the connection between the solar panel and the battery or the utility grid so that the solar panel can operate at its maximum power point. Mppt solar charge controller is far more advanced than the PWM controller. The main difference between the two is that the Mppt Solar Charge Controller allows up to 30% more power than the PWM solar charge controller and can be used for higher voltages. The efficiency of the solar charge controller mppt can be increased by up to 30%, depending on the battery voltage and working voltage (Vmp) of the solar panel.

How to Size Solar MPPT Charge Controller?

Add up the total watts of solar panels and divide by either 14.4 for 12-volt systems 28.8 for 24 volts or 58.8 for 48-volt battery banks. The calculated result is to provide you with the maximum output amperage of the solar mppt charge controller. Of course, in order not to waste power output, please set the size of the MPPT Solar Charge Controller to about two-thirds of the rated output of the controller.

20 amps are most efficient for a 30-amp controller
- 10 amp to 30 amp Mppt Solar Charge Controllers
45 amps are most efficient for a 60-amp controller
- 31 amp to 60 amp Mppt Solar Charge Controllers
65 amps are most efficient for an 80-amp controller
- 61 amp to 80 amp Mppt Solar Charge Controllers
80 amps are most efficient for a 100-amp controller
- 81 amp and higher Mppt Solar Charge Controllers

The number of solar panels you have and your energy needs

MPPT VS PWM, Differences:

1. Difference of Charging Method

PWM: 3 stage charging method (bulk, float, and absorb)

MPPT: Multi-Stage Charging(Bulk Charge, Balance Charge/Boost Charge, Absorb Charge, Float Charge)

2. Conversion Rates: PWM: 75%-80% Conversion Rate, MPPT: 99% Conversion Rate

3. Cost: PWM: $10 MPPT: from $60

How do MPPT charge controllers work?

Anyone familiar with the charging and discharging characteristics of the battery is familiar to the fact that the voltage of the battery varies with its charge content.As current flows from a high potential to low potential, the steeper the gradient or voltage difference, the greater is the flow of current.This potential gradient could be made steeper by two ways:
