# Which battery do I select - Dura-i or Solis?

For a Solis inverter under 'battery select' choose:

'Puredrive' for Gen 2 and Gen 1 Batteries. Depending on the firmware for the Duracell 5+ you could either select 'puredrive' or 'Duracell'. With all Dura5 Battery versions select 'Lithium Bat', if this is not an option with the Solis, then a Call to Solis is required to upgrade their inverter - RAI or RHI.

 

For a Dura-i inverter under 'battery select' choose: 'Pure Drive' for Gen 2, 'Duracell 5+' for Duracell 5+ and 'Dura 5' for Dura 5.

Puredrive Gen 1 Batteries are not compatible
