Do you have a question about the Unigy II and is the answer not in the manual?
Questions and answers
I have 2- Unigy 2 battery setups stacked in a 24V system I want to convert it to 48 it looks like I **** short 6 small bars to do this where can I get them? or can the batteries be rearranged to work with what I have
To convert a Deka Unigy II battery setup from 24V to 48V, you need to:
1. Determine the number of cells required: Each AGM cell typically provides 2V. A 24V system uses 12 cells (12 × 2V), while a 48V system uses 24 cells (24 × 2V). You will need to double the number of cells in series to reach 48V.
2. Order the correct configuration: When purchasing or modifying the battery bank, specify that you need a 48V system. The supplier can build the bank with the correct number of cells and amp-hour capacity.
3. Use included interconnects: The system includes battery interconnect cables and terminal bars, so no need to buy separate interconnects.
4. Ensure correct installation: Follow proper installation procedures, including correct polarity, torque values, and grounding using star washers with teeth facing the module.
5. Adjust charger settings: Ensure the charger is set to the appropriate float voltage for 48V (2.25V per cell) and performs optional equalizing charges only if compatible with connected equipment.
You can find the necessary parts and configuration through the supplier when ordering the battery bank, as they build it to your specified voltage and capacity.
