MPPT Vs PWM charge controller, কোনটি কিনবেন? জেনে নিন ভিডিও থেকে।

Basic Differences between MPPT solar charger controller and PWM solar charge controller. PWM: full Name - pulse width modulation Mppt :Maximim power point tracing. There are 3 mode of stage charging system at PWM charge controller. 1.Bulk mode battery charge 0-80% 2.Absorption Mode 81- 95 % 3.Floating charge 96-99% Mppt: This is DC to DC converter.where boost the panel volt and Am as par battery requirements. MPPT price more higher than PWM charge controller. Therefore 100 to 400 watt system pwm charge controller should be used.
