Frequently Asked Questions
12000XP or 6000XP: which do I need?
The 6000XP gives 6,000W output with 8,000W PV input, suited to cabins and smaller off-grid builds. The 12000XP gives 12,000W output with up to 24,000W PV input, built for whole-home and commercial systems. Size it to your loads and your planned array, not just today's usage.
Is the 12000XP UL 9540 certified?
No. The 12000XP is listed for closed-loop communication with batteries in off-grid non-UL 9540 installations. If your project requires UL 9540 certified grid-tied operation, the FlexBOSS18, FlexBOSS21 or 18kPV are the certified options.
What is the difference between the V1 and V2 12000XP?
The current product is the V2, which is what ships from BigBattery. If you are comparing against older listings or second-hand units, confirm the version, since the V2 is the revision currently supported and stocked.
Can the 12000XP be grid-tied?
It supports grid-tied, hybrid and off-grid installations, but its closed-loop battery communication is listed for off-grid non-UL 9540 installs. For a permitted grid-tied system with battery storage, a UL 9540 certified inverter is usually what an inspector will require.
What batteries work with the 12000XP?
All BigBattery batteries and all EG4 batteries, with closed-loop communication in off-grid installations. It works with 48V battery systems and supports solar plus generator input configurations.
