What Actually Sits Under the Panel

A hanging storage rod is a sealed enclosure carrying cells, electronics and a radio. Understanding its anatomy explains most of the product's behaviour.

One Rod, Four Functions

Optimization, storage, shutdown and networking sit in the same enclosure. Integrating them removes both cost and coordination from a retrofit.

DC Coupling Explained for Retrofit Storage

Where the battery sits relative to the inverter decides how many conversions energy passes through. DC coupling removes most of them.

Keeping the Original Inverter

Inverter replacement is the quiet deal-breaker in many retrofit budgets. Panel-mounted storage is designed to leave it alone.

Wireless Mesh Behind the Module Row

Communication cabling is a hidden cost in every distributed retrofit. A self-organizing mesh removes the trench, the conduit and the connectors.

From Array to Cloud: The Role of the Gateway

The gateway is where local control meets remote visibility. Its design decides what the platform can do when the network is unavailable.

Protocol Design for Large Terminal Counts

Thousands of small devices reporting frequently need a protocol written for density, not for throughput. Compact reporting is what makes it work.

One-to-Two Wiring and Modular Capacity

A single rod can serve one or two modules. That small decision shapes labour, capacity granularity and how a retrofit phases over time.

Mounting Options: Frame, Profile and Rail

Rails vary across plants built in different decades. Confirming the mounting interface early prevents a comfortable pilot from becoming a field surprise.

Converting a Module Row into a Dispatchable Asset

The end state of a retrofit is a row that can be told when to charge and when to discharge, with each panel reporting its own behaviour.

Questions This Topic Answers First

On the DC side of the plant, module by module, under the panels. The existing inverter, DC cabling and grid connection are untouched, so nothing about the plant's grid status has to be re-applied for.
