GivEnergy AIO 2 13.5kWh expansion battery
Doubling storage on an existing All-in-One is exactly what this 13.5kWh expansion battery is for: it adds a second 13.5kWh block to an AIO 2 so a household that has outgrown its original capacity gets there without a fresh system. The base unit stays; the expansion bolts on.
Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment.
Description
The AIO 2 ships as an integrated inverter-and-battery unit, and this expansion answers the common follow-up where usage has climbed and the original 13.5kWh is no longer enough. Adding the block takes an AIO 2 to double capacity while keeping the same footprint and controls. It belongs to the AIO 2 platform specifically, not the earlier AIO 1 or the loose low-voltage packs.

What it pairs with
This expansion is made for the AIO 2 base unit, the 12 kW 13.5 kWh All-in-One (GIV-AIO2-12KW-13.5KWH), and works alongside the AIO 2 Gateway and AIO 2 MPPT where the design calls for them. It does not fit the AIO 1 line, which uses its own gateway and units. Because supported expansion depends on the AIO 2 model and its firmware, confirm the pairing against GivEnergy's current All-in-One expansion list before ordering.
Single-phase only, and specific to the AIO 2 platform; it does not fit AIO 1 units or standard hybrid inverters. It adds capacity to an existing All-in-One rather than working on its own. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.
