Description: The monitoring background supports the PC host computer, supports the WIFI
module and the GPRS module to expand the APP cloud monitoring (optional). For details,
see the PC host computer and the APP user manual;
The controller defaults to lead-acid batteries. If you need to connect the other types of
batteries, you need to set the corresponding battery type and series number. For details,
please refer to the relevant settings of the PC host computer or APP manual.
1. Danger of electric shock! It is forbidden to touch the live parts of high voltage photovoltaic
modules with bare hands;
2. Make sure that the solar array voltage in the system does not exceed the maximum input
voltage range of the controller;
3. The system needs to be connected to the inverter. Please connect the inverter directly to
the battery. Do not connect to the load end of the controller.
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.
