Explain
：
monitoring background supports PC upper computer, supports WIFI module and GPRS
module to expand and realize APP cloud monitoring (optional). For details, please refer to operating
manual of PC upper computer and APP;
Step 3: checking connection
Check whether polarity of all wiring is correct and whether terminals are locked;
Step 4: Boot sequence
Recommended turn on, turn off sequence
：
close battery switch, photovoltaic switch or load switch in
turn
；
shut down photovoltaic and load switch, and then turn off battery switch.

Warning
！
1.Electric shock risk
！
Do not touch live parts of high voltage pv module with bare hands
；
2.Please ensure that solar array voltage in the system does not exceed the maximum input voltage
range of controller
；
3.The system needs to connect inverter, please connect inverter directly to battery, do not connect to
load end of controller;
