Sunwoda Atrix Max 14.3KW Lithium Battery

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.

*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.
