Does the Inverter/UPS come with internal batteries, or, do I need to connect batteries externally?

The battery configuration for different Inverter/UPS models can be classified as below:

  • Internal batteries only – In this case the batteries are provided internally and the UPS provides different runtimes depending upon the load connected to it.
  • Internal batteries with extendable runtime option – In certain models, additional batteries can be connected externally that together with the internal battery increases the UPS runtime. The option to connect additional batteries externally is not available with all models and you need to check the specifications of the specific model to ascertain this.
  • External batteries only – In these models, the batteries can only be connected externally.
