4.7. Connecting a Lithium Battery
When connecting a Lithium battery, follow the connection steps below and check ‘Setting up a Lithium Bat -
tery’ to connect with an inverter.
1.
Connect the correct diameter of cable in accordance with the battery manufacture specifications along
with recommended safety devices.
2. Connect a communication cable from the batteries to the inverter in compliance with the battery manu -
facturer guidelines. The cables have two ends, one to be specifically connected to the BMS and another
to be connected to the inverter, do not connect them incorrectly.
3. Connect the power and communication cables to the inverter correctly.
PLEASE NOTE
When connecting more than one battery, ensure they are set in the configuration of ‘master and
slave’.
PLEASE NOTE
Depending on the battery type, the inverter should be capable of controlling the batteries BMS. There-
fore, you need to set the protocol of the BMS on both the battery and the inverter.
When using more than one battery, the first battery will be the master, and the other batteries will be
the slaves. Please, check the battery manufacturer's specifications for proper operation.
To verify if the battery is communicating, access the Li BMS menu as detailed in the section ‘Setting
Up a Lithium Battery’ and check whether the values are realistic. It is important that the charge and
discharge limits in that page match the numbers expected for the number of batteries physically con-
nected.
4.8. Battery Temperature Sensor Connection
Without a remote temperature sensor, lead-acid batteries may undercharge or overcharge depending on
the ambient temperature of the installation environment. This may result in a fire hazard.
