Sunwoda Atrix Max 14.3KW Lithium Battery
When it comes to solar energy storage, the Sunwoda Atrix Max raises the bar. Unlike most LiFePO4 batteries that limit you to 80–90% of their rated capacity, the Atrix Max delivers a genuine 100% depth of discharge — meaning every one of those 14.3kWh is available when you need it most. Rated at 9,000 cycles and up to 1C* continuous charge and discharge, this floor-standing unit is engineered for the long haul. Backed by Sunwoda's globally trusted 280Ah LFP cells — used in electric vehicles and grid-scale storage worldwide — the Atrix Max is a storage solution built for South Africa's most demanding loadshedding conditions.
Key Features & Specifications:
- 14.3kWh at 100% Depth of Discharge — The full rated capacity is usable, giving you genuine 14.3kWh per cycle with no capacity held in reserve — a real advantage over batteries limited to 80–90% DoD; operating voltage 46.4V–55.2V
- Up to 1C* Continuous Charge & Discharge — 280A maximum continuous charge and discharge (~14.3kW); rated discharge 200A (~10.2kW); 420A peak at 10 seconds — handles heat pumps, large air conditioners, and commercial equipment without throttling
- 9,000 Cycle Life — Sunwoda's 280Ah LFP cells are rated at 9,000 cycles, translating to over 24 years of daily cycling at 100% DoD — exceptional longevity and one of the highest cycle ratings in the residential battery segment
- Massive Scalability — Up to 32 Units in Parallel — Scale from a single 14.3kWh unit up to 457.6kWh across 32 batteries; dual connection ports for easy parallel operation; built for residential, farm, and light commercial off-grid or backup systems
- Smart BMS with CAN/RS485 Communication — Dual-protocol CAN 2.0 and RS485 connectivity for seamless integration with Sunsynk, Deye, Victron, Kodak, Growatt, and other leading inverters; real-time monitoring and remote maintenance; active cell balancing and multi-layer protection built in
- Floor-Standing Cabinet with Optional Casters — Compact self-standing enclosure with a 500×970×265mm footprint; optional caster wheels for easy repositioning without lifting; IP20 for indoor use
- International Safety Certifications — IEC62619, CE, and UN38.3 certified for battery safety, transport, and grid compliance
Warranty Protection:
- 10-year warranty
- T&C may apply
The Sunwoda Atrix Max is the storage battery for installers and homeowners who demand real capacity, not rated capacity. Its 100% DoD means you get more usable energy per rand spent, and its 9,000-cycle rating and 1C* continuous discharge put it firmly in the elite tier of residential LFP storage. Backed by Sunwoda's global track record in EV and ESS cell manufacturing, the Atrix Max is a battery you can stake your energy independence on.

*C rate refers to the charge/discharge current as a proportion of battery capacity — a 1C rate charges or discharges the full rated capacity in 1 hour. Always verify the actual C rate for your specific battery and system configuration with the battery manual or your supplier before purchase or installation.
