NOTICE!
• In the case of one tower, there is only one master battery module (always the
uppermost battery module). While the master battery module connects to the
inverter, please confirm that the DIP switch 5 must stay in the ON position, as well
as the DIP switch 5 on the rest of the battery modules in the ON positions. Usually,
the DIP switch 5 will be slid to the ON position in the factory settings.
• In the case of more than two towers, except that the master battery module (always
the uppermost battery module) of the last tower shall be slid to the ON position,
the Dip switch 5 on the rest of the master battery modules shall be flipped up to the
OFF positions. Regarding the Dip switch 5 on the rest of the battery modules, please
confirm that they are in the ON positions. Usually, the DIP switch 5 will be slid to the
ON position in the factory settings.
• To adjust the DIP switch, a small flat-head screwdriver should be prepared by the
users themselves. Do not use a pencil. Graphite from the pencil is conductive and
may damage the DIP switch.

Black Start
The equipment can provide Black Start capacity, meaning that our energy storage inverter
and battery can continue to run even if the power grid and photovoltaic panel are out of
service. The startup procedure for Black Start is as follows:
• First stage: in case of pressing and holding the POWER button for less than 15
seconds, the status light will come on solid yellow light in the first 11 seconds and
then turn to solid green light in the last 4 seconds, and the SOC power indicators
will come on solid yellow light based on the actual remaining capacity.
• Second stage: after pressing and holding the POWER button for more than 15
seconds, the status light will flash yellow light every 1 second, and all the SOC
power indicators will remain on solid yellow light based on the actual remaining
capacity.
• Finally, release the POWER button.
