STURDX X20 IP66 Outdoor Battery Cabinet for 48V (51.2V) ESS – 8U Power Rack, ACU-Ready
STURDX X20 IP66 Outdoor Battery Cabinet for 48V (51.2V) ESS – 8U Power Rack, ACU-Ready
A Complete Outdoor Power System - Not Just a Battery Box
The STURDX X20 is designed for one purpose: to eliminate uncertainty in telecom and solar outdoor power deployments.
Most outdoor battery cabinets only store batteries.
They force rectifiers, DC distribution, and monitoring equipment into separate enclosures, creating extra wiring, extra failure points, and extra site work.
X20 integrates the entire power system into a single IP66 outdoor cabinet.
Dimensions
Cabinet Body (without base):
-
Height: 45 in
-
Width: 25 in
-
Depth: 32 in
Base / Plinth:
-
Base Height: 3.9 in
Total Installed Height:
-
Overall Height: 49.2 in
This size places X20 in the most widely deployed outdoor cabinet height range, while still accommodating an 8U equipment zone and full-size 51.2V batteries.
What the X20 Gives You
It gives you predictable installations.
Rectifiers, DC distribution, and monitoring equipment are installed in the upper 8U 19-inch rack zone, while heavy 51.2V battery modules are housed in the lower battery compartment. No second cabinet. No field improvisation.
It gives you operational control.
Power conversion, fused DC outputs, and system monitoring live in one sealed enclosure, so faults are isolated, alarms are visible, and maintenance becomes routine instead of reactive.
It gives you immediate and long-term cost protection.
By reducing site visits, rewiring, cooling retrofits, and premature battery failures, X20 protects the costs that never show up on a quote but always show up later.
How the Internal Architecture Works
Upper Section: 8U 19” Equipment Zone
This zone is dedicated to:
-
Rectifiers (AC to 48V DC power conversion)
-
DC distribution units (fused and breaker-protected outputs)
-
Monitoring & controllers (battery status, alarms, remote access)
-
Communication and control hardware
This allows the entire power system to be installed inside one cabinet.
Lower Section: Battery Compartment
The lower compartment is engineered for 51.2V (48V class) LFP battery modules, keeping heavy mass low for stability, airflow efficiency, and safe servicing.
This is intentional telecom-grade design, not a compromise.
Battery Compatibility
X20 is dimensioned around full-size rack battery modules, including:
-
51.2V 200Ah LFP modules
-
51.2V 150Ah modules
-
51.2V 100Ah modules
-
51.2V 50Ah (3U) modules
The cabinet depth is selected to support full-depth 200Ah modules with proper terminal clearance, airflow, and service access, avoiding the cable congestion and retrofit issues common in shallow outdoor cabinets.
Cooling Flexibility Without Redesign
The X20 is Air Conditioning Unit ready.
You can deploy with passive cooling where possible and upgrade to active air conditioning when load or climate demands it, without changing the cabinet platform.
One cabinet. Multiple deployment scenarios.
(600W and 2000W options available, compatible with 110V 50Hz, with higher-capacity versions offered for 220V as well.)
The X20 is designed for off-grid and hybrid power sites where cooling is intelligently managed. Standard AC-powered cabinet air conditioners operate during solar availability or high-temperature events, while critical loads continue to run on DC battery power when cooling is not required.
Typical Use Cases
-
Telecom backup power systems
-
Outdoor 48V / 51.2V ESS deployments
-
Solar + battery hybrid sites
-
Remote and unmanned infrastructure
-
Roadside and distributed power nodes
Why Customers Choose X20 Over Battery-Only Cabinets
Battery-only cabinets maximize raw battery count.
X20 prioritizes system integration and reliability.
You choose X20 when:
-
Rectifiers, DC distribution, and monitoring must live with the batteries
-
You want one enclosure instead of two
-
You value uptime over raw kWh density
-
You want repeatable deployments across multiple sites
Quick FAQ
Where are rectifiers installed?
In the upper 8U 19” rack section.
Where is DC distribution located?
In the same 8U zone, with fused or breaker-protected outputs.
Where is system monitoring installed?
In the upper rack area, allowing alarms and remote access without a separate cabinet.
Is this a battery-only cabinet?
No. It is a complete outdoor power system cabinet.

This IP66 outdoor battery cabinet is built for teams who are done fixing problems after installation. The STURDX X20 outdoor ESS cabinet eliminates the hidden costs that come with shallow enclosures, battery-only cabinets, and split power systems. By integrating rectifiers, DC distribution, monitoring, and 48V (51.2V) battery storage into a single outdoor power cabinet, X20 turns unpredictable field deployments into repeatable, controlled installations. You gain faster commissioning, cleaner wiring, and fewer failure points—critical advantages in telecom battery cabinet and outdoor energy storage cabinet deployments where uptime is non-negotiable.
Unlike standard outdoor battery enclosures that prioritize raw battery count, the X20 is optimized for system reliability and serviceability. Its dedicated 8U 19-inch equipment zone ensures that rectifiers, fused DC distribution units, monitoring controllers, and communication hardware are installed where they belong, while the lower compartment safely houses full-size 51.2V LFP battery modules, including 200Ah formats. The 32-inch cabinet depth is intentionally selected to support proper terminal clearance, cable bend radius, airflow, and maintenance access—solving the real-world issues that cause overheating, rewiring, and premature battery failure in undersized outdoor cabinets.
As an IP66-rated outdoor ESS cabinet, the X20 is designed to be installed once and left alone. It protects batteries and power electronics from dust, rain, and harsh environmental exposure, reducing site revisits and long-term operational risk. For telecom operators, solar EPCs, and infrastructure integrators, this means lower lifecycle cost, predictable performance, and a cabinet platform that scales across multiple projects without redesign. If your priority is long-term uptime rather than short-term savings, the STURDX X20 outdoor battery cabinet delivers value where it actually matters.
