Solhive

Swarm intelligence for your PV fleet.

Energy management software for photovoltaic systems with battery storage, EV chargers, heat pumps and switchable loads — from a single platform, vendor-independent, source-available.

What is Solhive?

Three pillars, one platform.

Solhive bundles the optimization of PV generation, storage, EV chargers, heat pumps and switchable loads into a single controller — regardless of manufacturer, regardless of how large the fleet grows.

Energy Management

Maximize self-consumption instead of feeding into the grid. Solhive automatically controls battery, EV charger, heat pump and switchable loads based on solar yield, electricity price and grid-compliance rules.

Vendor-Independent

Driver architecture for Modbus, SunSpec, MQTT, REST and Home Assistant. You are not locked to a single inverter or charger manufacturer — Solhive talks to all of them.

Fleet Management

Solar installers manage their customer systems centrally from one console. Updates, monitoring, support and co-branding — like a beehive, many cells.

For Solar Installers

Solhive is your central platform for managing customer systems at scale — without every installation becoming a one-off special case.

  • Heartbeat monitoring + remote support

  • Your own phone number and email in the end-user UI

For Homeowners

Solhive runs on your PV system's computer (Linux, Docker or Proxmox LXC) and gives you full control over your energy.

  • One app for PV, battery, charger, heat pump
  • Self-consumption made visible — and controllable
  • Automatic midday charging strategy
  • Source-available — you own your data
  • Updates come from your installer
Co-Branding

Your brand. Our platform.

Solhive was designed as a white-label platform from day one. End customers see your brand, your logo, your contact details — Solhive works in the background.

Pilot partners in Germany already run their customer systems under their own branding on the Solhive platform. Every system pulls a cryptographically signed branding manifest every 6 hours and adapts itself — no update, no manual intervention.

Source-Available

Code to inspect. License to rely on.

Solhive is source-available under the PolyForm Perimeter License. You can read, audit and locally adapt the code — and run it for your own PV system.

What this means in practice: data sovereignty through transparency, without anyone being able to turn the stack into a competing product. Fair for everyone involved.
