3. Installation

WARNING: DC (PV) INPUT NOT ISOLATED FROM BATTERY CIRCUIT
CAUTION: FOR PROPER TEMPERATURE COMPENSATION
THE AMBIENT CONDITION FOR CHARGER AND BATTERY MUST BE
WITHIN 5°C.
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).
● Improper internal temperature compensation (e.g. ambient condition
battery and charger not within 5°C) can lead to reduced battery lifetime.
● Battery installation must be done in accordance with the storage battery
rules of the Canadian Electrical Code, Part I.
● The battery connections (and for Tr version also PV connections) must be
guarded against inadvertent contact (e.g. install in an enclosure).
Tr models: use flexible multistranded copper cable for the battery and PV
connections: see safety instructions.
MC4 models: several splitter pairs may be needed to parallel the strings of
solar panels. (Maximum current through a MC4 terminal: 30A)
3.2 Grounding
● Battery grounding configuration: the charger can be configured as a
positive- or negative-ground system.
Note: apply a single ground connection (preferably close to the battery) to
prevent malfunctioning of the system.
● Chassis grounding: A separate earth path for the chassis ground is
permitted because it is isolated from the positive and negative terminal.
● NEC requires the use of an external ground fault protection device
(GFPD). These MPPT chargers do not have internal ground fault protection.
The system electrical negative should be bonded through a GFPD to earth
ground at one (and only one) location.
● The charger must not be connected with grounded PV arrays.
WARNING: WHEN A GROUND FAULT IS INDICATED, BATTERY
TERMINALS AND CONNECTED CIRCUITS MAY BE UNGROUNDED
AND HAZARDOUS.
