5.3 Shutdown
To properly shutdown: Turn off all loads and all energy inputs. Long press
the "ON/OFF" button for 2 seconds, releasing after the internal relay action
produces an audible “click.” The AC output will turn off and the LCD screen
will turn off. Press and hold the BMS “Reset” button until the red light
flash,BMS OFF. Finally, turn off all the breakers in the proper order (see
directly below).
Caution: If the unit will be unused for a long time and neither solar
power nor an AC charger will be connected, please turn off the BMS to
avoid the battery deeply discharging.
5.4 Battery protection
While AC output is turned on, protective actions are executed if certain
battery voltages are measured.

5.6 Connecting an Electric Generator:
When connecting an electric generator, make sure to follow these
guidelines:
5.6.1 Make sure the generator output voltage is within the MPS unit’s AC
input range (see Section 8). To connect the generator, first turn off the AC
Input and Output breakers. Wire the generator’s output to the MPS unit’s AC
input terminals according to the instructions (see Section 4.5). Start the
generator and make sure it is running stably. Make sure there are no loads
connected to the MPS unit’s AC or DC outputs. Finally, start up the MPS
unit.
5.6.2 After the MPS unit is started, connect loads one-by-one to the MPS.
5.6.3 We suggest the electric generator’s power output capacity be 2-3
times that of the MPS (i.e. 6000 – 9000 watts).
