1. DESCRIPTION
1.1 General
Series pass Pulse Width Modulation (PWM) charge voltage control
combined with a multistage charge control algorithm leads to
superior charging and enhanced battery performance. The filtered
PWM power control system uses highly efficient and reliable power
MOS ET transistors.
ully automatic temperature compensation of charge voltage is
available to further improve charge control and battery performance.
The optional battery temperature sensor is built for long term
reliability.
1.2 Features
PWM controller.
Charges two separate batteries. or example the starter battery
and the service battery of a boat or mobile home.
Programmable charge current ratio (standard setting: equal
current to both batteries).
Charge voltage settings for three battery types.
Internal temperature sensor and optional remote temperature
sensor.
Protected against over current.
Protected against short circuit.
Protected against reverse polarity connection of the solar
panels and/or battery.

4. TROUBLESHOOTING
1. LED blinking, short circuit, check the PV and battery, and make
sure that they are in correct connection.
2. LED slowly flashing: fully charged.
3. LED ON: charging.
4. LED frequent flashing: battery connected, no charge current.
5. LED O : no battery or over voltage.
1. Check wires
2. Reduce Amps if needed
3. Reset controller
5. SETTING MODE
After pressing the on/off push button during 5 seconds, one of the
three leds starts flashing. Each LED expresses different
specifications, choose the LED by pushbutton according to the
following information, and then press the switch for 5 seconds until
the number you need is flashing, choose one number as you need,
leave it for save.

want for battery #1, the controller will automatically calculate the
rest for battery #2.

Note: In the normal charging status, the controller will divide the
charging as the setting. When battery #1 is fully charged, more
charge current will be go to battery #2. When the controller detects
that only battery #1 is connected, all the charge current will go to
the battery #1 automatically.

1. DESCRIPTION
1.1 Généralités
La gamme utilise le contrôle de tension de charge "Pulse Width
Modulation" (PWM - Modulation de largeur d'impulsions) allié à un
algorithme de contrôle de charge en plusieurs étapes. Cela entraîne
un charge supérieure et améliore le rendement de la batterie. Le
système de contrôle de puissance PWM filtré utilise des transistors
de puissance MOS ET hautement efficaces et fiables.
La compensation entièrement automatique de température de la
tension de charge est faite pour améliorer le contrôle de charge et la
performance de la batterie. La sonde de température de la batterie,
qui est en option, est développée pour une fiabilité à long terme.
1.2 Fonctions
Contrôleur PWM.
Charge de deux batteries séparées. Par exemple, une batterie
de démarrage et une batterie de service d'un bateau ou d'un
mobile-home.
Ratio de courant de charge programmable (configuration
standard : courant égal pour les deux batteries).
Paramètres de tension de charge pour trois types de batterie.
Sonde de température interne et sonde de température à
distance en option.
Protection contre la surintensité.
Protection contre les courts-circuits.
Protection contre la connexion en polarité inversée des
panneaux solaires et/ou de la batterie.
