Overview
The Pytes V5 is the cold-climate evolution of the best-selling 48V rack battery: 5.12 kWh of LFP storage with an integrated heating film that automatically warms the cells below 41°F, allowing charging down to −0.4°F ambient. UL9540-certified as a system with major inverters, it stacks in racks or Pytes cabinets to any bank size.

Applications
The battery for unheated pump houses and mountain sites — self-heating means winter charging without a heated enclosure. Pairs with the Sol-Ark inverters and Pytes cabinets we stock.
Frequently Asked Questions
What makes the V5 different from the E-Box 48100R?
Same 5.12 kWh class, but the V5 adds the integrated heating film, newer UL9540 system certifications and a slimmer 3.2U chassis — the pick for cold climates.
How does the self-heating work?
Below 41°F the internal film warms the cells using PV, grid or generator power until they reach safe charging temperature — automatic, no external heater.
How many V5s can I stack?
Racks and Pytes cabinets hold 2–4+ modules; banks parallel to dozens of units for large systems.
