I am using 150W solar panel and 45A 12v starter battery for my small domestic off grid system

Now I need to increase one more battery to the system 

Q1. What is the best way that I should connect the battery to achieve best efficiency in parallel or series 

I know that when i connect series the output voltage go up to 24v that  does not a matter for my system 

Please advice 

  • Hello,
    This will depend on your system requirement and what voltage required by the load.

    Do you have a boost converter in your current system?

    Hello,
    Adding the battery in parallel will increase the current capacity of your battery.
