3.0 INSTALLATION
Connect the battery to the SS-MPPT. Refer to the wire
gauge chart on page 65 of this manual for correct wire
sizing.
If required, the negative battery connection may be
earth grounded. Use appropriate gauge wire and proper
grounding methods for the installation site. Grounding wires
must be of the same, or greater, cross-sectional area as the
PV wires.
Wire an in-line fuse holder no more than 6 inches (150
mm) from the battery positive terminal. DO NOT INSERT A
FUSE AT THIS TIME.
Step 3: Solar Wiring
WARNING: Shock Hazard
The solar PV array can produce open-circuit voltages
in excess of 60 Vdc when in sunlight. Verify that the
solar input breaker or disconnect has been opened
(disconnected) before installing the system wires.
AVERTISSEMENT: Risque de décharge électrique
Le réseau PV solaire peut produire des tensions de cir-
cuit ouvert supérieures à 60 V cc à la lumière du soleil.
Vériez que le coupe-circuit ou l’interrupteur d’entrée
solaire a été ouvert (déconnexion) avant d’installer les
câbles du système.
WARNING: Risk of Damage
Connecting the solar array to the battery terminal will
permanently damage the SunSaver-MPPT.
AVERTISSEMENT : Risque d’endommagement
La connexion du réseau solaire sur la borne de la bat-
terie endommagera le SunSaver de façon permanente.
The SunSaver MPPT can accept 12, 24, or 36V nominal
off-grid solar module arrays. Grid-tie solar module(s) may
be used if the open circuit voltage (V
oc
) does not exceed
the SS-MPPT 60 Volt maximum solar input rating. The solar
module(s) nominal voltage must be equal to or greater than
the nominal battery voltage. For 24 Volt systems, a 24, or
36V nominal solar array must be used.
