Ac output cable: Cu, L, N+PE,2*5 .0+5.0mm @40°C ambient with a max length
of 5m with operating time of the fuse is less than 5seconds, installation method
B2 according to EN60204-1:2006, annex D: cable in conduit cable trunking system,
number of loaded circuit only one . Use H07RNF (cord designation 60245 IEC66)
for an ambient temperature between 40°C and 60°C.
Note1: For conditions differing form those mentioned above ,dimension the
cables according to local safety regulations, appropriate input voltage and the
load and the load current of the unit.( You can choose a thicker cable but the
fuses must rated according to the cable.)
Note2: Fuses must be approved by Notified Body.
Inverter is not provided galvanic isolation from the mains to the PV array, backfeed
current to the array is 20A/250VAC for 3KW and 3.7KW; 25A/250VAC for 5KW,
based on the fuse provided in the mains. Also in the worst case .the reverse
current comprises the sum of the short-circuit currents of all intact lines.
There for the current-carrying capacity of the components and sub-assemblies
provided in the end-use system(connectors ,cables, junction box, switch ger,etc.).
and the reverse current PV module shall be considered based on the backfeed
current and reverse current. The direct current (DC) circuit breaker or fuse
between each solar generator and inverter shall be provided based on solar
inverter input ratings.
Select DC cables based on the above inverter back-feed current and Isc PV
rating and Vmax ratings.

When you want to build a self-use storage system , the battery is a necessary
part. The SK-SU E version series inverter provide the necessary part of the interfaces
to connect the battery to the inverter.
Make sure you select the correct specification cables for installation.
Otherwise the Power will make the cable hot or burnt, it could result
in death or serious injury.
WARNING!
Battery power connection .
1. Connect one side of the battery connect wire to the inverter.
2. Fit a fuse (63A slow blow) in the both positive and negative battery cable
as close as possible to the battery.
Battery communication connection .
Communication
The communication interface between battery and inverter is RS232 or CAN
with a RJ45 connector. The Pin definition is as below.
3. Connect the positive side of the battery connect wire to the positive side
of the battery , the negative side of the battery connect wire to the negative
side of the battery.
4. Make sure the positive and negative of the battery are correct.
