Hello, dear.

You can reset the inverter password by referring to the following steps, but you need to re-adjust your communication settings after resetting.

Resetting Password

Ensure that the SUN2000 connects to the AC and DC power supplies at the same time. Indicators and are steady green or blink at long intervals for more than 3 minutes.
Perform the following operations within 3 minutes:
1. Turn off the AC switch and set the DC switch at the bottom of the SUN2000 to OFF. If the SUN2000 connects to batteries, turn off the battery switch. Wait until all the LED indicators on the SUN2000 panel turn off.
2. Turn on the AC switch and set the DC switch to ON. Ensure that the indicator is blinking green at long intervals.
3. Turn off the AC switch and set the DC switch to OFF. Wait until all LED indicators on the SUN2000 panel are off.
4. Turn on the AC switch and set the DC switch to ON. Wait until all indicators on the solar inverter panel blink and turn off 30 seconds later.
Reset the password within 10 minutes. (If no operation is performed within 10 minutes, all inverter parameters remain unchanged.)

Thank you. I do need to tell you that I don't have the symbols that you say are for DC and AC. I just have the two led's one on the right for AC and the other on the left for DC, and I have one in the lower center for communication.
Also, today it is raining, so the DC may not be on for a while.
Thank you,
Mark
