What it is
The Sunpura S2400 is a true all-in-one home battery. The hybrid inverter, battery, battery management (BMS) and energy management (EMS) are combined in one stackable unit, so there is no separate inverter to buy, wire or warranty. It is built as a modular stack: a Power Box (A2400-ZA) on top of a Battery Box (B2400-ZA).
Built for South Africa’s tariff reality
As Eskom and municipal tariffs keep climbing, the S2400 lets a home store energy and lean less on the grid, with backup during outages as a bonus. Connect solar panels directly to the two MPPT inputs (2,000 Wp in total) to charge from the sun during the day, then run on stored power in the evening when tariffs are highest. Surplus solar is stored in the battery: the system is configured for zero export, so nothing is fed back into the grid and we make no feed-in claim. See the worked example of what shifting your evening load off the grid is worth per month.
Why all-in-one matters
- Inverter included: no separate inverter to source, mount or warranty, and fewer components to go wrong.
- Long cycle life: 8,000 cycles or more at 70% state of health, and LiFePO4 chemistry is inherently safer than NMC.
- Expandable: start at 2.4 kWh and stack up to 9.6 kWh in one system. Three units run in parallel for 28.8 kWh, and six units reach 57.6 kWh with the Sunpura parallel box. Those multi-unit figures assume every unit is stacked to its maximum and are drawn across three phases; most South African homes are single-phase, so ask us to size a multi-unit system.
- Pair it with the flexible solar panel kit: four 200 Wp panels in series sit comfortably inside one PV input.
- Simple to live with: managed from the Sunpura HOME app over Wi-Fi or Bluetooth.
Certification
The S2400 carries European and international certification (CE/EMC, RED, LVD, CB, RoHS, REACH, UN38.3, IP44, WEEE, VDE 4105, EN 50549 and more). We publish this as CE and CB certification, and we claim no South African approval. Specifications above are from the South African edition datasheet, revision 202609 V2.
