BATTERY CONNECTION
Preparation
Before connecting the batteries, install a separate DC circuit breaker between the inverter and the batteries.
Notes: 1.
For lead acid batteries, Flooded, Gel or AGM can be used. Please check maximum charging voltage and
current when first using this inverter.
2. If using Lithium Ferrite Phosphate batteries, consult with the battery manufacturer installer for the details.
What type of details does the installer need?
3. Use a 60VDC/160A circuit breaker.

WARNING.
To reduce the risk of injury, use the recommended cable size above. It is very important for system safety and
efficient operation to use the appropriate cable for battery connection.
Connecting the Batteries
Please follow below steps to implement battery connection:
Step 1. Make sure the nominal voltage for the batteries is
48VDC.
Step 2. Strip 15mm of insulation from the battery cables, and
then insert the conductors into cable ring terminals.
Step 3. Connect the external battery cable ring terminal to the
battery terminal. Following battery polarity guide
printed near the battery terminal.
RED cable to the positive terminal (+);
BLACK cable to the negative terminal (-).
WARNING.
Shock Hazard. Installation must be performed with care due
to high battery voltage in series.
CAUTION.
Do not place anything between the flat part of the inverter
terminal and the ring terminal. Otherwise, overheating may occur.
CAUTION.
Do not apply anti-oxidant substance on the terminals before terminals are connected tightly.
CAUTION.
Before making the final DC connection or closing DC breaker/disconnector, be sure positive (+) is connected to
positive (+) and negative (-) is connected to negative (-).
