Confirm with the makers before you buy
- Whether one battery can take the inverter's full current. The inverter's max battery current is 200 A. This battery is rated for 14.3 A charging and 14.3 A output. Ask how many batteries to run in parallel.
- Which firmware versions support this pairing. We don't track firmware.
- That your cable lugs fit the inverter's battery studs (M8-1.25 bolt) and the battery's terminals (Not published).
- How to install both safely, from each maker's manual and your local code.
This result checks two things: the battery's voltage suits the inverter, and the inverter maker lists this battery for closed-loop communication (the battery tells the inverter how to charge it). It doesn't check current limits, charge settings, firmware, cable sizes, or safe installation. Confirm those with both makers before you buy.
