Figure 26 Connecting Demonstration for Lead-type Battery Storage System
1)
The PV power should be lower than 4.2kW;
2)
The emergency load connected should be no more than 2kW;
3)
A 32A/400V AC Breaker and 300mA leakage protector should be installed between the system
and the grid;
4)
A 16A/400V AC Breaker and 300mA leakage protector should be installed between the system
and the emergency load.
