The shipment leaves as a documented kit
Rods, housings, cells, harnesses and gateways are packed as separate line items with a bill of materials, so the destination can classify components rather than a finished storage unit.
Product & Solution
Hanging PV Micro-Storage System
Storage rods hang directly under your existing PV panels on the mounting rail. Per-panel wireless optimization, five-layer safety, and cloud EMS dispatch — built to upgrade operating plants, not replace them.
How It Works
From Panel to Grid in Six Steps
Each storage rod is a self-contained unit: optimizer, battery, BMS and wireless node. Together they form a plant-wide dispatchable system.
1
PV Panel Generates
Existing solar modules continue producing as usual. The micro-storage rod is hung beneath the panel on the mounting rail, connected in series with the panel string.
2
Per-Panel Optimizer Tracks
Each rod carries an independent MPPT optimizer that tracks its own panel in real time, eliminating shading, hotspot and mismatch losses to increase total generation.
3
Storage Rod Charges
Surplus solar energy charges the on-rod battery during peak generation. Each rod stores 3.2 kWh of LFP cells with independent BMS managing voltage, current, SOC, temperature and balancing.
4
Wireless Mesh Coordinates
Rods communicate via a self-healing wireless mesh network. No extra cabling between modules. One gateway manages up to 30,000 devices across the plant.
5
EMS Cloud Dispatches
The cloud EMS platform dispatches charge and discharge across the plant, monitors every rod in real time, and generates performance reports. Supports both local tariff rules and grid dispatch.
6
Grid Export or DC Load
Stored energy is dispatched during curtailment windows, peak tariff hours or grid demand events. The system supports both AC grid export and direct DC supply for telecom and industrial loads.
Six Core Advantages
Every Advantage Answers a Real Project Constraint
Integrated upgrade capabilities: generation + storage + monitoring + dispatch + safety in one clamp-on system.
Higher Efficiency
Low-voltage DC storage on the PV side achieves 10%+ charge/discharge efficiency vs AC-side alternatives. Per-panel MPPT recovers 8%-20% generation gain from shading and mismatch.
Higher Safety
Dispersed cells under the rails mean no concentrated thermal-runaway risk. Independent BMS per rod plus panel-level DC arc-fault shutdown with second-level cutoff of faulty branches.
Lower Cost
15% lower initial PV system cost vs centralized storage. No land cost, no separate grid-connection approval for storage, no civil works. Pay-as-you-grow phased investment.
More Energy
Optimizer recovers 8%-20% yield lost to shading, soiling and string mismatch. Curtailment absorption stores otherwise wasted power for dispatchable export.
Second-Level Response
Rapid shutdown cuts voltage below safety limits in under 2 seconds. Wireless mesh enables plant-wide dispatch with low latency and self-healing reliability.
Easy O&M
Weld-free clamp-on installation. Single rod swap without affecting neighbors. Wireless mesh means no extra communication cabling to maintain. IP65 rated for harsh environments.
CKD / SKD Local Assembly
Why Knocked-Down Export Moves the Duty Line
Duty is assessed on how a product is classified, not on how much energy it stores. Shipping modular kits instead of finished units lets the destination schedule treat the shipment as components, which is where a reduction of up to 70% against a finished unit becomes possible.
Housings close on site, without special tooling
Bars weigh roughly 28 kg and clamp on weld-free, so assembly and mounting are handled by the local team with normal PV installation equipment and no dedicated assembly line.
Paperwork prepared for local-content review
We supply the component list, assembly steps and test records used in local-content and certification submissions, which is what most incentive and duty programmes ask for.
What the 70% figure does and does not mean
The saving is the difference between the duty assessed on a finished unit and on the classified component kit under the destination tariff schedule. The actual rate depends on the HS code applied, local-content thresholds and how much assembly happens on site, so the number is quoted per market before an order. Product certification (IEC 62109-1), IP65 rating and the five safety layers are unchanged by the assembly location.
Pain vs Solution
Each Feature Answers a Real Project Constraint
Each capability below is paired with the pain it removes, so your team can map them directly to your own site conditions.
No Extra Land Needed
Pain
Containerized storage reserves large plots and needs civil foundations.
Solution
Bars hang under existing PV mounting rails. No land reservation, no civil works, no structural change to the array.
Module-Level Wireless Control
Pain
String-level control hides module mismatch and shading losses.
Solution
Each bar runs independent mesh wireless and its own MPPT, balancing every module precisely to lift yield.
Distributed Safety by Design
Pain
Centralized battery stacks raise thermal-runaway and insurance concerns.
Solution
Cells are spread across the array, so a single fault is contained locally. Independent BMS plus DC arc protection keeps fire risk controllable.
Weld-Free Modular Quick-Swap
Pain
Welded container systems are hard to move when a project ends.
Solution
Bars clamp on and unclamp off. Retire a site and redeploy the same assets to another plant with high reuse rate.
CKD Export & Local Assembly
Pain
Imported turnkey systems miss local-content rules and subsidies.
Solution
Components ship knocked-down and housings assemble on site, supporting local manufacturing requirements and subsidy applications.
Phased Investment, Buy as You Grow
Pain
Megawatt-scale capex forces all-in decisions before proof.
Solution
Start with a pilot of a few dozen bars, verify gains on your own meter, then scale capacity in steps.
Five-Layer Safety
Dispersed Cells, Independent Protection
Five independent layers of protection from cell architecture to rapid shutdown — no single point of failure can cascade.
Layer 1
Dispersed Cell Architecture
Battery cells are spread across the array under individual panels, not concentrated in a single cabin. A single fault is contained locally rather than cascading into system-wide failure.
Layer 2
Independent BMS per Rod
Each storage rod has its own BMS managing voltage, current, SOC, temperature and cell balancing. Faults are isolated at the rod level.
Layer 3
Panel-Level DC Arc-Fault Shutdown
Real-time detection of DC arcing at the panel level. Short-circuit and other risks trigger second-level cutoff of faulty branch circuits to reduce DC fire risk.
Layer 4
Rapid Shutdown < 2 Seconds
System-wide rapid shutdown brings voltage below safety limits in under 2 seconds, meeting firefighter safety requirements and insurance standards.
Layer 5
IP65 + Environmental Hardening
Each rod is rated IP65 for outdoor use. Validated for heat, dust, salt spray, humidity and vibration in desert and plateau conditions.
Cloud EMS
Observable, Measurable, Controllable, Adjustable
The cloud EMS platform turns thousands of distributed rods into a single dispatchable power plant.
Observable
Real-time visibility into every rod: SOC, temperature, charge/discharge status and health.
Measurable
Per-panel generation gain, storage efficiency and curtailment absorption tracked with meter-grade accuracy.
Controllable
Cloud dispatch engine schedules charge and discharge based on tariff, curtailment windows and grid signals.
Adjustable
Self-healing wireless mesh adapts to topology changes. One gateway manages up to 30,000 devices with automatic re-routing.
