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 substrate, with the power
terminals facing downwards. Observe a minimum clearance of 10 cm
under and above the product for optimal cooling.
● 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.
We recommend using a direct battery voltage sense source (BMV,
Smart Battery Sense or GX device shared voltage sense) if larger
temperature differences or extreme ambient temperature
conditions are expected.
● Battery installation must be done in accordance with the storage
battery rules of the Canadian Electrical Code, Part I.
● The battery and PV connections must be guarded against
inadvertent contact (e.g. install in an enclosure or install the optional
WireBox M).
3.2 Grounding
● Battery grounding: the charger can be installed in a positive or
negative grounded 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.
● The USA National Electrical Code (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 plus and minus of the PV array should not be grounded. Ground

WARNING: WHEN A GROUND FAULT IS INDICATED,
BATTERY TERMINALS AND CONNECTED CIRCUITS MAY BE
UNGROUNDED AND HAZARDOUS.
