3.7 Battery Terminal Components
If you choose lead-acid battery, you are allowed to use AGW-type, flooded-type and
Gel-type. It is necessary to consider that the battery voltage to connect with the inverter
is 48V.
Considering the installation environment and operation safety, please pay attention to
the following points:
The natural surrounding ventilation of Lead-acid battery should be well and the
environment temperature is better around 25±10
℃
.
Fix the bolts of wire terminal to prevent the battery from sparking and poor connection.
The battery should avoid direct sunlight, DON’T put the batteries in the environment
with lots of radiation, infrared radiation, ultraviolet radiation, organic solvent gas
and corrosive gas.
The different batteries with different capacity and functionality can’t be interconnected
with each other, check the total voltage, polarity of positive and negative port before the
installation of end connection device and turning on the battery system.
Ensure the installation site has enough carrying capacity to support the battery system.
3.7.1 Lead-acid Battery
If you choose a lithium battery, you are allowed to use Pylontech
, BYD
and
D
yness.
3.7.2 Lithium Battery
Considering the installation and operation safety, please pay attention to
the following points:
Before compeleting the final DC connection or closing DC breaker, please ensure the
correct polarity of battery connection and positive (+) must be connected to BAT (+)
and negative (-) must be connected to BAT (-).
Please carefully read the user manual of the battery and strictly follow the precautions
in the battery manual.
3. Installation
3. Installation
Insert the ring terminal of battery cable flatly into battery connector of inverter and make
sure the bolts are tightened with torque of 1.2-1.6Nm.
Make sure polarity at both the battery and the inverter is correctly connected and ring
terminals are tightly screwed to the battery terminals.
Note:
Before connecting the battery, please carefully read the user manual of the
battery and perform the installation exactly as the battery manufacturer
requests.
