In the world of rack-mounted energy storage batteries, two world renowned brands often go head-to-head: Pytes ESS and PylonTech. Both are widely used in the solar, hybrid, and off-grid systems but if you take a closer look it reveals that Pytes has made several smart design decisions that give it a real edge.
Let's break down the key differences:
Battery Capacity and Format
Pytes:
• 5.12kWh per unit
• 1U rack height
• High energy density, efficient use of space
PylonTech (e.g., US5000):
• 4.8kWh per unit
• 2U rack height
• Slightly lower energy capacity per unit
Winner: Pytes
With more capacity in a slimmer form factor, Pytes delivers better energy-per-U performance, ideal for maximising rack space.
Winner: Pytes
Pytes protects your investment in all seasons, while PylonTech requires extra measures in cold climates.
Fire Suppression System
Pytes:
• Integrated fire suppression module
• Enhanced safety in enclosed environments
PylonTech:
• No built-in suppression
• Standard protection only via BM
Winner: Pytes
Built-in fire suppression makes Pytes a safer choice, especially for rack enclosures in homes, containers, or commercial spaces.
Intelligent Battery Management & Pre-Charge
Pytes:
• Smart internal balancing
• Pre-charge circuitry built in
• Safer and easier to scale with new or mixed-age batteries
PylonTech:
• Standard balancing only
• Pre-charge requires careful configuration or external support
Winner: Pytes
Pytes is more plug-and-play, with better long-term reliability in scaled or upgraded systems.
Compatibility with Victron Energy Systems
Winner: Pytes
Both work with Victron, but Pytes tends to be more seamless out of the box.
Mechanical Design and Build Quality
Pytes:
• Steel construction
• Lockable front access
• Heavy-duty rack rails and secure mounting
PylonTech:
• Aluminium/plastic casing
• Standard rack ears
• Less robust feel in rugged installations
Winner: Pytes
Pytes racks are built for industrial environments with better durability and safer handling.
Conclusion: Pytes Rack Batteries Lead the Pack
For installers, system designers, and off-grid users seeking top-tier safety, cold-weather performance, and reliability, Pytes rack-mounted batteries simply offer more than PylonTech, without a huge price difference. If you’re building systems that need to just work, regardless of weather or workload, Pytes is the battery to beat.
