Picture this: it's a Wednesday afternoon and your client calls to say their rooftop solar plant has been underperforming since morning. You're at your office. The site is 80 km away. By the time your engineer reaches, diagnoses the issue, and returns — you've burned most of the day and a chunk of your budget, and the client is already frustrated.

This is the everyday reality for solar EPCs, O&M teams, and system integrators across India. The problem isn't the inverter. The problem is visibility — or rather, the complete lack of it.

ubiqedge's KLEON 4G Smart Dongle, paired with the SAMASTH IoT Cloud Platform, is built to solve exactly this. Real-time inverter data, remote diagnostics, and over-the-air control — without leaving your desk.

Why Unplanned Site Visits Are Killing Your Margins

Every unnecessary site visit is a cost you shouldn't be bearing. Consider what goes into a single reactive visit: engineer time, travel expenses, vehicle costs, and the opportunity cost of pulling someone away from productive work. For a portfolio of 10–50 sites spread across Maharashtra or Gujarat, even two or three reactive visits a month add up to a serious operational drag.

More critically, by the time someone physically reaches the site, the issue may have already resolved itself — or worsened. You're always reacting, never anticipating.

Remote monitoring changes that equation entirely.

How KLEON Gives You Real-Time Site Visibility

The KLEON 4G Dongle plugs directly into your solar inverter via RS-485 Modbus, connects over 4G LTE Cat-1, and begins pushing live data to the SAMASTH cloud platform within minutes of installation. No complex networking setup, no site infrastructure required. If there's 4G signal at the site — and across most of India's rooftop and C&I locations, there is — KLEON is online.

Once connected, your SAMASTH dashboard reflects the real-time health of every inverter in your portfolio. The platform uses clear status indicators:

Status

What it means

🟢  Online

Inverter communicating normally. Data is flowing. Everything at the site is working as expected.

⚫  Offline

Plant is in nighttime state. No generation is expected. This is normal behaviour.

🔴  On-Error

Issue detected — inverter fault, connectivity drop, or data gap. Alert triggered immediately for remote investigation before dispatching anyone.

Knowing your site status in real time, from anywhere, eliminates a large proportion of the reactive visits that eat into your O&M budget.

Remote Diagnostics and OTA Control: Fix Issues Without Moving

Knowing there's a problem is only half the battle. KLEON and SAMASTH give you the tools to investigate and often fix issues without stepping outside your office.

Over-the-Air (OTA) Configuration

KLEON supports full over-the-air configuration updates. If your device needs a parameter change — polling intervals, data push frequency, Modbus register mapping — it can be pushed remotely through SAMASTH. No physical access to the device required.

Remote Inverter Control

Beyond monitoring, SAMASTH lets you perform remote commands on the inverter — including restart sequences and operational controls. Issues that would previously require a site visit to manually cycle a device can now be handled in seconds from the dashboard.

Intelligent Alerts

SAMASTH monitors inverter performance continuously and triggers alerts when generation falls outside expected thresholds, when communication drops, or when fault codes are detected. Your team knows about an issue before your client does — giving you time to investigate remotely and respond proactively.

💡  The practical result: Most communication and connectivity issues are diagnosed and resolved remotely in under 15 minutes. Genuine hardware faults — where a physical visit is unavoidable — are identified precisely, so your engineer arrives knowing exactly what to fix.

Built for Indian Solar Conditions — and Indian Regulations

KLEON isn't a generic IoT device retrofitted for solar. It's purpose-built for the demands of India's solar monitoring landscape.

📡  4G LTE Cat-1 Connectivity

Reliable data transmission across FDD and TDD bands used by Indian operators — even at remote rooftop and ground-mount sites.

🔌  RS-485 Modbus Support

Plug-and-play compatibility with a wide range of solar inverters already deployed in the field. No third-party adaptors or custom cabling.

🏛️  MNRE RMS Compliant

Data push architecture meets PM Surya Ghar Muft Bijli Yojana and MNRE RMS requirements — subsidy eligibility protected.

🔒  End-to-End Encryption

TLS/SSL encryption with OTP-based authentication ensures every data packet is secure from inverter to cloud.

🌡️  Industrial-Grade Enclosure

IP55 rated, operating range of −30°C to 65°C. Designed to survive rooftop heat, dust, and monsoon humidity year-round.

📊  Audit-Ready Data Logs

Industrial-grade logging ensures complete data traceability for financial reconciliation, subsidy claims, and regulatory audits.
