Selection of Fuse and Cables
Mains cable (AC line cable) shall be short circuit protected and thermal overload protected.
Always fit the input cable with fuse. Normal gG(US:CC or T ) fuses will protect the input cable in
short circuit situation. They will also prevent damage to adjoining equipment.
Dimension the fuses according to local safety regulations. Appropriate input voltage and the
related current of the solar inverter.
AC output protected by external fuse (gG rated current 20A/250VAC for 3KW and 4KW;
25A/250VAC for 5KW) provide in all live connections to the AC supply.
The rated short circuit breaking capacity of the above protective device shall be at least equal to
the prospective fault current at the point of installation.
See section technical data of this manual for details.
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 be 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, back-feed current to
the array is 20A/250VAC for 3KW and 4KW; 25A/250VAC for 5KW and 6KW, 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 back feed 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.
6.7.3 Battery Connection
When you want to build a self-use storage system, the battery is a necessary part. The ESC-
Hybrid inverter provides the necessary part of the interfaces to connect the battery to the inverter.
