The Problem

What Stops Plant Owners From Adding Storage

Three constraints come up in every retrofit conversation. They are structural, not commercial — and they are exactly what a hanging micro-storage design removes.

Land & Civil Cost

Containerized BESS demands reserved plots, foundations and long EPC approvals. Retrofitting an operating plant can cost more than the energy it saves.

Fire & Arc-Fault Risk

Stacked central batteries concentrate thermal-runaway risk, and DC arc faults are a common cause of plant fires. Owners and insurers scrutinize every design.

Mismatch & Curtailment Loss

Shading, soiling and string mismatch silently cut yield, while curtailment wastes sellable power. Plant-level storage does not recover module-level losses.

What We Build

Storage That Hangs Under Your Panels

Four capabilities work as one system: distributed capacity under the rails, module-level optimization, wireless coordination and structural safety.

No Extra Land Needed

Storage rods hang directly under existing PV panels on the mounting rail. No battery cabin, no concrete foundation, no civil works. Retrofit without reserving new land.

Per-Panel Wireless Control

Each rod carries its own MPPT optimizer and wireless Mesh node. One independent controller per panel removes mismatch loss and recovers 8%-20% yield.

Dispersed Safety by Design

Cells are spread across the array under the rails. A single fault is contained locally rather than cascading. Independent BMS + DC-arc rapid shutdown on every rod.

Modular & Phased Purchase

Start with a pilot of a few dozen rods, verify gains on your own meter, then scale panel-by-panel. SKD knock-down export supports local assembly and subsidy qualification.

How It Works

Less Loss, More Generation, More Sellable Power

Energy flows from your existing modules through bar-level storage and wireless coordination to the grid or DC loads - without touching your land or your inverter room.

1

PV Generation

Existing modules keep producing as usual

2

Storage Bar

Module-level charge & discharge under the rail

3

Wireless Mesh / EMS

Plant-wide dispatch and monitoring

4

Grid Export / DC Load

More sellable power, fewer losses
