Step 3: Check the connection
Check that all wiring polarity is correct and the terminals are locked;
Step 4: Power On Sequence
Recommended opening and closing sequence: sequentially close the battery pack switch,
photovoltaic switch or load switch;
Turn off the PV and load switches before turning off the battery switch.
