1. Structural Frame
A future‑proof, brand‑agnostic, installer‑friendly 48 V battery cabinet engineered for Jakiper, SIPANI, and any modern LiFePO₄ module. Featuring full‑height slotted uprights for industrial‑grade flexibility and strength.
2. Universal Tray System
Each tray is designed to slide out on locking heavy‑duty runners, rated for 100–150 kg. This premium feature allows the installer to pull the tray completely out, ensuring no leaning into the cabinet with a heavy module.
3. Future-Proof Dimensions
Engineered to accommodate the largest standard 48 V battery modules on the market, ensuring total compatibility with both current and future system designs.
Internal Width: 560 mm
Internal Depth: 420 mm
Adjustable Tray Spacing: 250–450 mm
Capacity: 4 tray positions with built-in expansion room
Load Rating: 100 kg minimum per shelf/tray
4. Battery Compatibility
Designed for seamless integration with leading 48 V LiFePO₄ battery modules. The universal mounting architecture provides native support for major brands while remaining fully adaptable for custom setups.
Certified Brands: Jakiper, SIPANI, and standard 19-inch rackmount modules.
Mounting Flexibility: Slotted trays accommodate varying manufacturer width and depth dimensions.
Wiring Clearance: Generous rear and side spacing for clean DC busbar and communication cabling.
Q: Does the cabinet come fully assembled?
A: It ships flat-packed to save on transport costs, but all heavy-duty runners come pre-mounted to the uprights for incredibly fast and straightforward on-site assembly.
Q: Can multiple cabinets be linked together in parallel?
A: Yes. Side-by-side punch-out knockout panels are integrated into the chassis design for clean, protected multi-cabinet busbar and communication routing.
Q: What is the maximum weight capacity per tray?
A: Each sliding tray is rated for a heavy-duty load of 100–150 kg at full extension, easily supporting top-tier LiFePO₄ modules.

Question: One more quick one — when you’re setting up the backup circuits, do you account for the inverter’s negative‑sequence current limits during an asymmetrical fault? Some manufacturers cap the negative‑sequence injection pretty aggressively, which can cause odd behaviour on the non‑backup side if the load centre isn’t isolated cleanly.
Answer: In most modern hybrids, the negative‑sequence current during an asymmetrical fault is limited in firmware to comply with grid standards (typically around 1.1–1.2 pu, depending on the model). As long as the backup panel is fed via a dedicated output and the non‑backup circuits stay on the grid side of the ATS/main contactor, any odd behaviour on the non‑backup side is handled by the grid protection, not the inverter.
So the key is:
– the inverter’s current‑limiting and sequence control are manufacturer‑defined,
– the installer’s job is to ensure clean segregation of backup vs non‑backup load centres, so an asymmetrical fault seen by the inverter doesn’t partially energise the non‑backup side.
