CAUTION:
breaker between inverter and batteries.
NOTE1: Please only use sealed lead acid battery, vented and Gel battery. Please check
maximum charging voltage and current when first using this inverter. If using Lithium
iron or Nicd battery, please consult with installer for the details.
NOTE2: Please use 60VDC/300A circuit breaker.
NOTE3: The overvoltage category of the battery input is II.
Before connecting to batteries, please install separately a DC circuit
Step 2: Use two battery cables. Remove
insulation sleeve 12 mm and insert conductor
into cable ring terminal. Refer to right chart.
Step 3: Remove battery cover and follow
battery polarity guide printed near the battery
terminal! Place the external battery cable ring
terminal over the battery terminal.
RED cable to the positive terminal (+);
BLACK cable to the negative terminal (-).
Please follow below steps to implement battery connection:
Step 1: Check the nominal voltage of batteries. The nominal input voltage for
inverter is 48VDC.
WARNING! Wrong connections will damage the unit permanently.
