3-1-1. DC Input Connection ①②
Follow the instructions to connect the battery cables to the DC input terminals of
the inverter. The cables should be as short as possible (less than 6 feet / 1.8
meters ideally) so that they can handle the required current in accordance with the
Electrical Codes and Regulations. The size of the cable should be thick enough to
limit the voltage drop to less than 2% when carrying the maximum input current
to prevent freque
nt low-input voltage warnings, an
d shutdown. UVP (Under
Voltage Protection) warning may result if there is excessive voltage drop across
the DC cables between the batteries and the inverter. Increasing your DC cable
size will help improve the situation.
Batteries are capable of providing very large currents in case of short circuit. In
case there is a short circuit in the cable run between the batteries and the input
terminals of the inverter, it will result in over
heating / melting of the cables and
consequent risk of fire and injury, To prevent possibility of this hazard, use Very
Fast Acting DC Fuse in line with the positive cable. The fuse should be as close to
the positive battery terminal as possible. Use Bussmann ANN series fuses
