Battery Input connection wires diameter selection Model 1012 1024 2012 2024 3024 3048 4048 5048 6048 Battery Current 125-180A Connection wires distance 0-1.5m 50m m2 70m m2 Connection wires distance 1.5-4.0m 70m m2 90m m2 Notes: Connection wires must be required to use copper wires, usually, using one connection wires is the best. If can t find the same size connection wires, for example, 90m m2 connection wires, can use two 50m m2 or three 35m m2. So as long as the wires diameter can t meet requirement, can increase wires quantity, shorter and thicker connection wires can improve machine performance, So do your best to reduce the connection wires distance. Installation 1 Try to put the machine beside battery cabinet 2 Put the machine in the cool, dry and ventilate place 3 When ensuring the normal air outlet of machine, can put the machine in any direction. 4 Whether buying the standard connection wires from supplier (about 1.5M), or buying them in local market, please choose suitable wires by refer to the table Battery Input connection wires diameter selection. If don t have suitable wires, can use multiple wires, for example, 90m m2 connection wires, can use three 35m m2. 5Choose suitable fuse by contrasting the installation drawing, DC terminal fuse range is 100-500A 6 Fuse should connect battery wires in battery section, when the machine have fault, can ensure the machine safe. If using isolate air switch, please ensure the switch s rated power. 7 Ensure when the machine is installed under the condition of power off. 8 Ensure AC terminal cut off, connection inverter output remaining current breaker(remaining current breaker is used for grounding protection) and overload tripping. AC input terminal is according to power supply needed, if Max. Output current is 30A, you can choose 40A fuse, if you use standard 13-16A current, just choose 20A fuse.
