Cloud-based PV control for DSOs: aggregate, dispatch and manage feed-in

Distributed solar has become an operational problem for distribution grids. In high-penetration areas, rooftop and C&I systems generate in the same midday hours, driving feed-in peaks and local congestion that grid operators now have to handle daily. As more solar connects to the low-voltage grid, the ability to reduce its output on demand is shifting from a nice-to-have to a regulatory expectation.

The traditional solution, is to install control hardware at every site, but this approach is not the most cost-efficient for a network full of smaller residential and C&I plants.

In this blog, we introduce Synergi's PV Manager — one of the only cloud-based control options on the market that enables DSOs to remotely control solar production per grid area and at transformer level, without any hardware. The sections below follow the way you, as a grid operator, would assess PV Manager, giving you a clear view of how it fits your current stack:

Architecture

PV Manager doesn't replace your existing control infrastructure. It adds a software-based layer for solar that runs in parallel with the systems you already operate, so you can bring distributed PV under management without re-architecting anything else — and scale it up over time as more capacity connects.

As the solar aggregation and control layer, it works from the boundaries you set as you onboard assets: which plants, transformers, areas or which part of the network, and how much to reduce production. From there it lets the grid operator execute against your fleet within those limits, sending commands cloud-to-cloud, and factors in grid signals and constraints from your systems via API. That keeps it focused on one job: turning distributed PV into capacity you can control on demand fully cloud-to-cloud.

Data aggregation

PV Manager enables you to connect to different inverter brands, such as SMA, Fronius, Huawei, and Sungrow inverters in production, with other integrations in active development. This allows you to build a mixed-brand fleet of pre-pooled and aggregated residential and C&I solar assets into a single portfolio — ready to be controlled and dispatched, with live production, status and fault visibility across every connected site.

Load control & orchestration

PV Manager dispatches the aggregated solar fleet as a single unit via API: remote curtailment and ramp-up, automatic curtailment during negative-price or surplus periods, reduction of feed-in across a defined network area during a congestion event or grid emergency, and operator-initiated emergency reduction.

Deployment

Because PV Manager is hardware-free and cloud-to-cloud, bringing solar under control skips the parts of a load-control project that usually cost the most time and carry the most risk: no field deployment, no device procurement, no installation schedule.

A plant is connected through its inverter cloud in software, using the plant owner's OEM credentials, so a first set of sites can be connected and validated with live activation tests in a matter of weeks, then scaled, rather than over the multi-year horizon of a hardware programme.

PV Manager: Built for and with grid operators

PV Manager was developed alongside European partners. BKW in Switzerland was among the earliest design partners, contributing requirements across multi-brand fleet management, emergency curtailment and trading-system integration; BKW Power Grid is testing cloud-based solar control ahead of Switzerland's 2028 DSO control mandate. Solar asset manager Youdera helped shape the C&I fleet side.
