Yes, it is basically an autoswitching junction block. The transformer, pump and alternative power supply all connect to the block. If the main power is interupted it automatically switches to the back up. Any supply of 12-24V is acceptable, including solar panels. For a battery you will need some sort of charger be it a solar trickle charger or a maintenance trickle charger. We recommend gel cell batteries and keep in mind all the precautions of working with lead acid batteries. They do only work with the 6101, 6201, 6301 and 6212 with new power supply as well as the 6055. It works best with the 6101 and 6055 in terms of battery life.
