PWM solar regulator Victron Energy BlueSolar-LCD&USB 20A DUO, for charging two independent batteries with an integrated LCD and two USB ports.
Its construction is designed for small island solar systems, especially cars and boats, or wherever it is necessary to charge two independent batteries. The controller allows you to set the ratios for charging batteries 1 and 2 - in the factory setting, the ratio is set to 50/50%. In the normal state of charging, the controller divides the charging current according to the settings. When battery # 1 is fully charged, more charging current will flow to battery # 2. When the controller detects that only battery # 1 is connected, all charging current automatically flows into battery # 1.
To charge a 12V battery, the solar panel must have 36 cells, or to charge a 24V battery, the panel must have 72 cells. With a 12V battery, a maximum panel power of 240Wp can be connected in parallel. With a 24V battery, a maximum panel with a power of up to 480Wp can be connected The advantage is very simple and undemanding installation and reliable operation.
Built-in clear LCD display For status monitoring and parameter setting.
Easy installation 1. Connect the battery1 - plus and minus. 2. Connect the battery2 - plus and minus. 3. Connect the solar field - plus and minus. The reverse order applies during disassembly.
Incorrect connection order can damage the BlueSolar PWM charge controller! 1. Before the first installation, make sure that the battery is charged. 2. The cable to the battery should be as short as possible to minimize losses. 3. The controller is only suitable for lead and LiFePO4 batteries. 4. The charge controller is only suitable for controlling solar panels. Never do not connect another charging source to the solar controller.
Main function • Three-stage battery charging • External temperature sensor included • 2 outputs for 2 separate batteries. • Battery type: Lead and LiFePO4 • Protected against polarity reversal of solar panels and / or batteries. • USB output for charging phones and tablets. • Thermal protection.
