| PWM Solar Charge Controller | MPPT Solar Charge Controller | |
| Advantage | 1. Simple structure, Low cost | 1. The utilization of solar energy is much higher up to 99.99% |
| 2. Easy to increase capacity | 2. Output current ripple is small, reduce the working temperature of the battery , prolong its life | |
| 3. Conversion efficiency is stable , basically can be maintained at 98% | 3. Easy to control the charging mode, the battery charging optimization can be realized | |
| 4. Under high temperature (above 70), the utilization of solar energy is equal to MPPT, economically application in tropical area. | 4. The response speed of PV voltage change is very quick, this will be easy to achieve adjustment and protection function | |
| 5. Wide PV input voltage range, convenience for customers to connect in different ways | ||
| Disadvantage | 1. PV input voltage range is narrow | 1 . High cost, Large size |
| 2. The solar tracking efficiency is lower under full temperature range | 2. The conversion efficiency is low if the sunshine is weak | |
| 3. The response speed of PV voltage change is slow |
