Anker - SOLIX BP1000X Expansion Battery for C1000X Double Capacity (1056 Wh Capacity) - Black

Dear Retmtrmdc, Yes, the interface cord for connecting the two power supplies is included in the package with the extra battery. If you have any other questions, feel free to let us know!

Dear customer, thank you for your interest in our products. Know that the battery capacity increases to 2112Wh after connecting the BP1000X to the C1000X. This setup can last around 19 hours to run a 100 watt light bulb.

Thanks for your interest in our product! The S2000 uses an integrated motherboard design, which allows it to achieve an excellent balance between capacity and portability in a much more compact size. Because of this all-in-one structural design, as well as considerations around safety and overall user experience, the BP1000X is not compatible with the Anker SOLIX S2000. If you need more capacity, the S2000 does offer a flexible alternative: you can expand your backup setup by using multiple S2000 units through AC output in parallel applications. This distributed backup approach can be especially useful if you want power in different areas of your home. Compared with one large traditional installed backup system, it offers several advantages: - plug-and-play with no home circuit modification - easy to move and use wherever needed - reduced risk of total power loss concentrated in a single system If you need any further assistance, please feel free to contact Anker SOLIX Support at +1 (800) 988-554 or via email at support@ankersolix.com — we’re always happy to help!

Thank you for your interest in our product. Unfortunately, the expansion battery can only be charged and discharged through the main unit, the C1000, and cannot be charged directly via solar panels. If you need further assistance, please feel free to contact Anker Solix Support at +1 (800) 988-554 or via email at support@ankersolix.com.

The battery does have a signwave inverter.
