Identity and scope

Purchase policies below are a dated source review, separate from individual product specifications and price observations.

Manufacturer/brand, seller and installation provider are separate roles. A merchant profile does not certify that every product is made by that merchant. Affiliate approval and endorsement are not established by these links.

Manufacturer support/warranty is separate from the seller’s shipping, return and installation obligations.

Do not show BigBattery’s stated battery term on every accessory, third-party inverter or historic product.

BigBattery also has a legacy-product route for older documentation.

Support hours differ between page sections; no universal hour promise is made here.

Identity

The official site uses the BigBattery manufacturer/store brand and also sells other brands. The exact catalog label BigBattery matches its own brand; EG4 and other manufacturers remain separate identities.

Warranty handling and support

The official policy describes BigBattery battery coverage separately from one-year accessories and non-BigBattery manufacturer coverage. Contact BigBattery technical support with issue evidence before repair/return; shipping responsibility can change after year one. Exact battery terms, exclusions and dated documents govern coverage.
