Marstek Mars I Plus stackable high-voltage battery module 5.12kWh LiFePO4
This is the 5.12kWh battery module of the Marstek Mars I Plus storage system: automotive-grade LFP cells in a stackable, plug-and-play pack designed to work with the Mars I Plus hybrid inverter in a V-Boost high-voltage configuration (800V nominal, 650–950V range). Real-time cell balancing prevents the weakest module from limiting the whole pack.
Capacity is built to measure: start with one module and grow to six modules for 30.72kWh per system, or up to 122.88kWh by paralleling four Mars I Plus systems. The cells exceed 6,000 cycles while keeping 80% of their capacity for up to 15 years, with a 10-year warranty. IP65 enclosure with fire- and heat-resistant materials, operation from -25 to 60 °C and noise below 30 dB.
