Low capacity MPPT solar charge controllers of a current rating from 20A to 40A are utilized for some, various applications including off-network lodges and homes, Rv's, boats, trains, media communications and remote site reinforcement. These mid-range MPPT sunlight based charge regulators are accessible from various producers, yet this audit will zero in on the most famous and best quality charge regulators from the most legitimate makers which have been available for a considerable length of time.
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.
Welcome to Buy the Best MPPT Solar Charge Controller on PowMr.
- MPPT Solar Charge Controller is best for professional owners who need one controller that accomplishes heavy tasks (Home Power Supply, RV Solar Power, Boat, Hybrid Solar Power, and off-grid power station). Because of its robust features, it can save you money by cutting other expenses.
- PWM Solar Charge Controller is best for small off-grid power applications that don’t need any other features and has not have much budget. If you just want the basic and economical charge controller for a small lighting system that doesn’t try to fit the needs of others, the PWM controller is the way to go.
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
Main Features of Solar MPPT Charge Controller?
- MPPT can handle inclement weather
- MPPT controller is much more expensive than PWM controller
- MPPT charge controller has electronic protection and adaptive charging function
- The MPPT solar charge controller reduces the complexity of the system, while the output efficiency of the system is high
- The solar mppt charge controller can be applied to other renewable energy sources, such as small water turbines, wind turbines, etc.
Please note that before purchasing a mppt solar charge controller, you should consider the following:
- Please pay attention to your upper voltage limit
- Get a higher ampere mppt solar charge controller
- 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
