General Information - Victron energy BlueSolar PWM DUO-LCD-USB Manual

1. General Information

Always connect battery 1 first, in order to allow the Controller to
•
recognize system voltage.
Use a 12V (36 cells) solar array for a 12V system.
•
Use a 24V (72 cells) solar array for a 24V system.
•
The BlueSolar PWM DUO 12V|24V|20A LCD-USB series uses Pulse Width Modulation
(PWM) charge voltage control combined with a multistage charge control algorithm. This
leads to superior charging and enhanced battery performance. The filtered PWM power
control system uses highly efficient and reliable power MOSFET transistors.
2. Features
Three stage battery charging [bulk – absorption – float]
•
External Temperature sensor included
•
• 2 Battery outputs for 2 separate batteries.
Battery type: Lead-Acid and LiFePO4
•
Protected against reverse polarity connection of the solar panels and/or battery.
•
USB output for charging telephones and tablets.
•
• Temperature protection.
3. Installation
Important note: always connect the battery 1 first.
