Common questions

What people ask about the AC500 + 2× B300K Batteries (5.5 kWh)

What is actually in the AC500 + 2× B300K Batteries (5.5 kWh)?
The bundle ships as a single SKU with all components in one order. The Bill of Materials section above lists every item with its quantity. Each component links to its standalone product page if you want to dig into the detail specs of any single part. Solar panels are not included; see the bundle vendor page for compatible add-on options.
Can I expand the system later?
Yes. Most Bluetti systems in this class accept additional battery modules up to a manufacturer-stated max. The bundle ships with 2 batteries and 5.528kWh of capacity. You can buy extra batteries a la carte from the same vendor without rebuying the inverter.
Is this cheaper than buying the components separately?
Yes. Vendors price bundles below the sum of standalone SKU prices to incentivize the larger purchase. The exact savings shifts daily as component prices move; the Bundle savings section above shows the live delta against current observed prices for each component.
