the 12V battery version and 33.0 VDC for the 24V battery version to prevent permanent
damage to the unit. Please observe the following precautions:
• Ensure that the maximum charging voltage of the external battery charger / alterna-
tor / solar charge controller does not exceed 16.5 VDC for the 12V battery version and
33.0 VDC for the 24V battery version
• Do not use unregulated solar panels to charge the battery connected to this unit.
Under cold ambient temperatures, the output of the solar panel may reach > 22 VDC
for 12V Battery System and > 44 VDC for the 24V Battery system. Always use a charge
controller between the solar panel and the battery.
• Do not connect this unit to a battery system with a voltage higher than the rated bat-
tery input voltage of the unit (e.g. do not connect the 12V version of the unit to 24V
battery system or the 24V version to the 48V Battery System)
Preventing Reverse Polarity on the input Side
When making battery connections on the input side, make sure that the polarity of bat-
tery connections is correct (Connect the Positive of the battery to the Positive terminal
of the unit and the Negative of the battery to the Negative terminal of the unit). If the
input is connected in reverse polarity, DC fuse(s) inside the inverter will blow and may
also cause permanent damage to the inverter.
