Pulsar Light · Retrofit
Retrofit Energy Gateway
Run your plant against hourly prices without touching it. Pulsar Light is a compact energy management gateway fitted to already-installed solar plants: it establishes a local connection without changing the on-site inverter and logger setup, carries the data to the cloud and applies the hourly plan on site.
Existing plant, new economics
Hourly netting does not require replacing the site — it requires managing it. Pulsar Light does that with the smallest possible intervention: your setup stays, we make the decision.
Your setup is untouched
The existing inverter and logger stay in place. The manufacturer's own monitoring portal keeps running on a separate channel — you lose nothing you have today.
The decision stays on site
The hourly plan comes down from the cloud but executes locally. If the connection drops, the device keeps running the schedule it holds.
Commissioned in one visit
Designed to need neither a cabinet nor site engineering; commissioning typically completes in a single site visit.
Features
Built to do the right job, not fewer jobs
Retrofit installation
The existing inverter and logger setup stays in place and the manufacturer's monitoring portal keeps running.
Hourly plan, local execution
The schedule built from hourly prices runs on site; it keeps running when the cloud is unreachable.
Energy-layer control
Hourly netting, market implementation and battery setpoint management — at second-to-minute resolution.
Multi-brand support
Works with common inverters and loggers over 2× Ethernet, RS485 and CAN.
Architecture
Connects to the site without disturbing it
Pulsar Light connects locally to the on-site logger and inverters, applies the hourly plan there and carries data to the cloud over a connection it opens outbound. The manufacturer's own portal keeps running on a separate channel.
- Local connection over 2× Ethernet, RS485 and CAN
- The hourly schedule is held and executed on site
- Outbound connection to the cloud — no inbound tunnel required
- The manufacturer's monitoring portal is unaffected
Comparison
Pulsar Light or Pulsar Edge?
They operate at different layers. Whichever layer your site needs is the product you want.
| Pulsar Light | Pulsar Edge | |
|---|---|---|
| Target site | C&I and mid-scale, existing installation | Industrial facility, mixed sources, new build |
| Control layer | Energy layer — seconds to minutes | Power layer — sub-second |
| Typical job | Hourly netting, market implementation, battery setpoint | In-facility load management, multi-source optimisation, SCADA/RTU |
| Installation | Single site visit, no cabinet required | Cabinet mounting and site engineering |
| Connectivity | 2× Ethernet, RS485, CAN, external antenna · 24 V DC supply | Multi-protocol, multi-port |
Use Cases
Where it earns its place
Unlicensed rooftop and ground-mount PV
On sites moving to hourly netting, it manages generation against hourly prices and reports what curtailment returned.
C&I site with storage
Where a battery exists, charge and discharge join the same hourly plan, moving midday generation into valuable hours.
Multi-site portfolio
Commissions dozens of sites on the same pattern; each site is calculated with its own consumption profile and tariff.
Mixed-brand fleet
Connects inverters and loggers from different manufacturers to one platform, removing the need for a separate system per site.
