Hoymiles S-Miles Cloud

S-Miles Cloud is the monitoring platform from Hoymiles Power Electronics Inc., the company named in the footer of hoymiles.com. According to the vendor's product page, it shows PV generation, energy storage and electricity consumption in real time. Its most specific claim is module-level monitoring of voltage, current, power and temperature for each panel, with data updated at one-second intervals.

Users can drag and drop PV modules to match the physical layout of a site, and the page describes remote operation and maintenance, including adjusting settings and upgrading firmware. Access is from a PC, smartphone or tablet. The homepage states no headquarters or country of establishment; its footer shows a Chinese ICP registration number. The product page gives no price, trial or usage limit, so the commercial terms are unknown from what we read.

• Real-time generation, storage and consumption. The product page says users can view PV generation, energy storage and electricity consumption in real time. It does not say how real time is defined for the whole-system view as opposed to modules.
• Module-level readings. Voltage, current, power and temperature are shown for each panel. This helps locate an underperforming module, though the page does not describe thresholds, alerts or how long history is kept.
• One-second data updates. Module data updates at one-second intervals according to the page. That is a concrete figure, but the page does not say whether it applies to every device model or connection type.
• Drag-and-drop site layout. Users can drag PV modules onto a layout that matches the site. A visual map makes a faulty panel easier to find on a large roof, but the page does not mention import from design software.
• Remote settings and firmware upgrades. Remote operation and maintenance covers managing and controlling the system, adjusting settings and upgrading firmware. The page does not list which settings can be changed or how an upgrade is scheduled.
• Access from PC, phone and tablet. The platform is reached from a PC, smartphone or tablet, with a mobile login and an app page linked. The pages we read do not name iOS or Android support.
• Encryption and access control. The page states advanced encryption and access control for data protection. It names no hosting location or certification, so the statement cannot be checked against a standard.

• An installer maintaining rooftop plants with many panels. Per-module voltage, current, power and temperature, shown on a layout the installer draws, help pinpoint a weak panel without climbing on the roof. Alert settings are not described.
• A system owner with battery storage. Generation, storage and consumption appear together in real time, so the owner can see how the battery and household load interact. The page gives no detail on reports or history.
• A service company handling firmware. Remote settings changes and firmware upgrades reduce site visits. The page does not describe permissions, rollback or which devices accept upgrades, so test on one plant first.

The product page links a mobile login and an app page, and says the platform is accessed from a PC, smartphone or tablet. The Hoymiles global app page shows only the title S-Miles Cloud and the company name, without naming platforms or prices, so the store listing has to be found separately.

The pages we read describe features rather than a setup procedure: they do not explain registration, adding a plant, pairing a gateway or inviting an installer. The trial application on the product page refers to a separate Free Design Tool, not to S-Miles Cloud itself. A practical first step is to ask the installer or Hoymiles which gateway and microinverter models are needed for the one-second module data.

S-Miles Cloud from Hoymiles Power Electronics Inc. shows voltage, current, power and temperature per module with updates each second, and lets users drag modules onto a site layout. Remote operation covers settings changes and firmware upgrades.

The page cites advanced encryption and access control but names no hosting location or certification, and it states no prices, trial or limits. The footer carries a Chinese ICP number, not a stated country.

Hoymiles S-Miles Cloud is entry #7 of 14 in the solar monitoring platforms list: it follows GoodWe SEMS Portal and comes before SolaX Cloud. No numeric score is attached; established products follow the challengers in their ranked order.

The vendor states no country of establishment, so Hoymiles S-Miles Cloud is left out of the regional count for this list.

In the catalogue: No pricing, trial or usage limits stated on the product page.

The S-Miles Cloud page states no pricing, free access, trial or usage limits. The trial application it mentions refers to the separate Free Design Tool, so it should not be read as a trial of the monitoring platform. The global app page names no prices either. Without published amounts, a buyer cannot tell whether monitoring is bundled with Hoymiles hardware, charged per plant or offered in tiers. The sensible approach is to ask the installer or the vendor for the terms in writing before commissioning, particularly where a plant has many modules or where firmware management is part of a service contract.

Access works from a PC, smartphone or tablet, and the page links a mobile login without naming iOS or Android.

Real-time views span PV generation, storage and electricity consumption.

Remote operation and maintenance include adjusting settings and upgrading firmware.

The pages read do not mention portfolio features, API access or third-party devices, and the app listing shows only a title and company name.

The page states advanced encryption and access control for data protection. It names no hosting location, certification, retention period or export option. The company in the footer is Hoymiles Power Electronics Inc., and the homepage states no headquarters or country of establishment; the footer shows a Chinese ICP registration number, which is a web registration rather than a stated place of establishment.

Module data updates every second, which means a large volume of readings, yet the pages do not say how long that history is stored. A buyer with data protection duties should request the vendor's privacy terms and hosting details before registering plants.
