Comparison of parameters between the new and old BWITT inverters:
| Serial number | name | Parameters of the old inverter | New inverter parameters |
| 1 | DC input anti-reverse and EMI | Have | Have |
| 2 | Bypass switching time | 5MS | 5MS |
| 3 | Output AC voltage | 220±1.5% | 220±1.5% |
| 4 | Overload capacity | 120%, 30 seconds | 100%-120% 60 seconds 121%-150% 10 seconds |
| 5 | LCD liquid crystal display | Adopt 122*32 dot matrix (display 2 lines) | Using 128*64 dot matrix (display 4 lines) |
| 6 | Number of keys | 4 buttons | 6 buttons |
| 7 | LCD contrast adjustment | no | The LCD screen can be adjusted to make the display more friendly |
| 8 | Dry contact | 3 way dry contact | 5-way dry contact |
| 9 | Mode selection | Can be set in the LCD screen | Can be set in the LCD screen |
| 10 | Indicator light | Single color (complex fault indication, see table 1 of the manual for details) | Two-color (fault indication is simple and easy to understand, see manual 6.2 indicator display table for details) |
| 11 | Communication Interface | RS232 or RS485, you can only choose one of the two | RS232 and RS485 are online at the same time |
| 12 | Baud rate change | Automatic recognition (low recognition rate and unreliable) | Optional changes (intuitive, accurate and reliable) |
