Installation - Victron energy BlueSolar MPPT 150/45-Tr Manual

A 25mm² cable, for example, should have at least 196 strands
(class 5 or higher stranding according to VDE 0295, IEC 60228
and BS6360).
An AWG2 gauge cable should have at least 259/26 stranding
(259 strands of AWG26).
Maximum operating temperature: ≥ 90°C.
Example of suitable cable: class 5 "Tri-rated" cable (it has three
approvals: American (UL), Canadian (CSA) and British (BS))
In case of thicker strands the contact area will be too small
and the resulting high contact resistance will cause severe
overheating, eventually resulting in fire.

3. Installation

3.1 General
● Mount vertically on a non-flammable surface, with the power
terminals facing downwards.
● Mount close to the battery, but never directly above the battery
(in order to prevent damage due to gassing of the battery).
● Grounding: the heatsink of the controller should be connected
to the grounding point.
● Use one grounding point only (preferably close to the battery,
for safety reasons) to which the battery negative or battery
positive should be connected. Do not also connect the the solar
array negative to ground. This would result in unwanted ground
currents
Tr models: use flexible multistranded copper cable for the battery
and PV connections: see safety instructions.
MC4 models: several splitter pairs will be needed to parallel the
strings of solar panels.
