Figures are as Naxion prints them in its datasheets, brochure and online calculator; they are not independent test results. Rated energy is battery voltage × Ah. Where Naxion's documents differ, both versions are listed. For example, the 3.5 kW sodium-ion unit is 24 V 100 Ah in the specification sheet and Naxion's calculator, and 24 V 160 Ah in the brochure. The inverter ratings of the LFP versions are taken from the sodium-ion datasheet of the same size. Our price-list names differ from Naxion's: NX PRO 1250, 2500 and 5000 are the 1 kW, 2 kW and 5 kW LFP units. The batteries of the NX PRO 7500, NX PRO 12000, NX PRO 20000, NX 5kW–8kW and NX 18kW Sodium are planning estimates on their product pages, scaled from Naxion's own batteries, until Naxion's datasheets are confirmed. We confirm the exact unit and battery in your written quote.
Temperature, charging and life
- Sodium-ion battery: −30 °C to 90 °C (Naxion brochure).
- Complete inverter units: −10 °C to 45–55 °C depending on the model (Naxion specification sheets). Install them in a ventilated room.
- Charge and discharge: up to 3C continuous charge (about 20 minutes) and 5C continuous discharge for heavy inductive loads, as the brochure states.
- Cycle life: up to 6 times that of lead-acid (brochure).
- Transfer time: 10 ms for computers, 20 ms for household appliances (brochure).
