COURANT DE COURT-CIRCUIT ÉLEVÉ, À UN INCENDIE
OU À UNE EXPLOSION PROVENANT DE GAZ REJETÉS
DANS L’AIR. VEUILLEZ PRENDRE LES PRÉCAUTIONS
NÉCESSAIRES.
AVERTISSEMENT:
Ces instructions d’entretien sont exclusivement réservé-
es à des techniciens qualiés. Pour réduire le risque de
choc électrique,
ne réalisez aucun entretien autre que celui stipulé dans

QUE LE CIRCUIT EST SOUS TENSION, A MOINS QU’lL
NE S’AGISSE D’UN EMPLACEMENT NON DANGEREUX.
ATTENTION:
Pour diminuer le risque d’incendie, ne connectez
l’alimentation qu’à un circuit équipé d’une protection
maximum par dérivation contre les surintensités ne
dépassant pas le courant nominal du modèle de la
page 2, conformément à la norme du Code National de
l’Électricité (NEC), ANSI/NFPA 70.
ATTENTION:
Unité bénécie d’aucune protection de retrait de batterie.

un bref pic de tension de charge (au-dessus du 15V limite
de règlement) qui peuvent endommager les équipement
sensibles.
Installation Safety Precautions
WARNING:
This unit is not provided with a GFDI device. This
charge controller must be used with an external
GFDI device as required by the Article 690 of
the National Electrical Code for the installation
location.
• Mount the SunSaver indoors. Prevent exposure to the
elements and do not allow water to enter the controller.
• Install the SunSaver in a location that prevents casual
contact. The SunSaver heatsink can become very hot during
operation.
• Use insulated tools when working with batteries.
• Avoid wearing jewelry during installation.
• The battery bank must be comprised of batteries of same
type, make, and age.
• Do not smoke in the vicinity of the battery bank.
• Mount the controller at least 3 ft (1 m) away from vented
batteries unless separated by a barrier or located in a
separate compartment.

adaptées.
• Ce contrôleur de charge ne doit être connecté qu’à des cir-
cuits en courant continu. Ces connexions CC sont identiées
par le symbole ci-dessous:
• Le contrôleur SunSaver doit être installé par un technicien
qualié conformément aux règlementations électriques du
pays où est installé le produit.
• Un moyen d’assurer la déconnexion de tous les pôles de
l’alimentation doit être fourni. Cette déconnexion doit être
incorporée dans le câblage xe.
• À l’aide de la borne de mise à la masse du SunSaver (dans le
compartiment de câblage), un moyen permanent et able de
mise à la terre doit être fourni. La xation de la mise à la terre
doit être xée contre tout desserrage accidentel.
• Les ouvertures d’entrée au compartiment de câblage du

2.0 GENERAL INFORMATION
2.1 Overview
Thank you for selecting the SunSaver solar charge
controller. The SunSaver is an advanced PWM solar battery
charger and load controller for stand-alone PV systems.
The SunSaver battery charging process has been
optimized for long battery life and improved system
performance. Self-diagnostics and electronic error protection
prevent damage when installation mistakes or system faults
occur.
Although the SunSaver is very simple to install and use,
please take the time to read this operator’s manual and
become familiar with the controller.

3.0 INSTALLATION INSTRUCTIONS
3.1 General Installation Notes
• Read through the entire installation section before
beginning installation.
• Be very careful when working with batteries. Wear
eye protection. Have fresh water available to wash
and clean any contact with battery acid.
• Use insulated tools and avoid placing metal objects
near the batteries.
• Explosive battery gases may be present during charg-
ing. Be certain there is sufcient ventilation to
release the gases.
• Do not install in locations where water can enter the
controller.
• Loose power connections and/or corroded wires
may result in resistive connections that melt wire
insulation, burn surrounding materials, or even cause
re. Ensure tight connections and use cable clamps
to secure cables and prevent them from swaying in
mobile applications.
• The SunSaver charging algorithm is compatible with
lead-acid or NiCd batteries. NiMH, Li-ion, and other
battery chemistries are not compatible with the
SunSaver charging algorithm.
• The SunSaver Battery connection may be wired
to one battery or a bank of batteries. The following
instructions refer to a singular battery, but it is implied
that the battery connection can be made to either one
battery or a group of batteries in a battery bank.
