3. The MPPT and PID function
When P00.11=100, it will execute the following macro modification
1. P47.01=211 (auto start, enable MPPT, enable auto switch)
2. P07.03=47 (Mains action relay, normally closed for mains (when
the automatic switching mode is 2)
3. P07.16=1.000 Relay 1 action delay 1s
4. P07.17=1.000 Relay 1 reset delay 1s
5. P47.06=600s Mains switching judgment 10min
6. P47.07=3600s Mains use time 60min.
When P00.11=101, it will execute the following macro modification
1. P01.07=8 enable PID function
2. P40.06=50.00 The default setting is the midpoint
