Be carefull about modifying inverters or any cabinets with long term warranties because modifying may result in sending your unit for repair and not getting exchange units in the event of a warranty issue. Outback is served in parts so that may not be an issue, solark is too soon to tell. Fronius refused to warranty inverters because they say the shell was modified. But hey thats my luck
