Giving you ultimate charging flexibility, the new dual battery charging solar bundle is the smart way to stay off the grid longer. This 12V 50A dual battery solution not only charges your house battery bank and trickle charges your starter battery bank while on the move, but thanks to the MPPT solar input, you can also charge while parked. If you need more power, you can expand up to 660W of solar input giving you plenty of options. Featuring reliable multi-stage charging and multi-chemistry functionality, the dual battery charging solar bundle has you covered whether you’re using Flooded, Gel, AGM, or Lithium batteries. Now you can unlock monitoring and control features exclusively using the BT-2 Bluetooth Module and Renogy DC Home App (available in both the App Store and Google Play).
