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.
Pilot live
Energy management software for photovoltaic systems with battery storage, EV chargers, heat pumps and switchable loads — from a single platform, vendor-independent, source-available.
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.
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.
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.
Solar installers manage their customer systems centrally from one console. Updates, monitoring, support and co-branding — like a beehive, many cells.
There are excellent niche tools for surplus charging and polished manufacturer apps. But between charging tool, inverter app and cloud portal, one question remains open: who actually optimizes the whole system? That is exactly where Solhive comes in.
Tools like evcc solve PV surplus charging brilliantly — Solhive built its own charger drivers following their proven blueprints. But control does not stop at the wallbox: battery strategy, heat pump, switchable loads and the power budget at the grid connection all come from one place. For example: “car at 80 % by 7 a.m., charge the battery in the cheap night window, never overload the grid connection” — three jobs, one controller.
Manufacturer apps end at the edge of their own product range. Solhive speaks Modbus, SunSpec, MQTT, REST and Home Assistant — mixed systems are the norm: Deye next to SMA, any wallbox, the heat pump via SG-Ready. And when a device gets replaced, your controller, history and settings stay.
Commercial energy management systems live in someone else's cloud: subscription, data outflow, black box. Solhive runs on hardware in your own home, keeps controlling during internet outages, and the source code can be inspected. Cloud connectivity only where you want it: remote access and installer support.

¹ e.g. evcc — excellent for surplus charging and the blueprint for Solhive's own charger drivers.
Deye, SMA, Huawei, Solax, Sungrow, Fronius and more. Pluggable drivers for open protocols.
Single-, two- and three-phase chargers with dynamic load distribution. Our own drivers, modeled on evcc blueprints.
SG-Ready, midday block, flow-temperature boost on PV surplus. Pluggable heat-pump drivers.
“Car at 80 % by 7 a.m.”, “charge battery in the price window” — forecast-based, via web UI or Telegram.
Grid-connection budget: chargers, battery grid-charging and loads share the available power — phase-aware.
German grid-operator curtailment done right: 4.2 kW cap, control signals, wattage reduction.
Midday charging strategy, charge-SOC limits, TOU (time-of-use) for Deye, Huawei, SMA and more.
Every job explains itself: why is it (not) running? Live status, reason and event timeline.
Your own logo, colors and contact details for partners. Manifest-based, cryptographically signed.
Per-MPPT forecast, 24h weather strip, day/month/year statistics, CSV export.
Linux, Docker or Proxmox LXC. Keeps controlling without internet — your data stays at home.

Solhive is your central platform for managing customer systems at scale — without every installation becoming a one-off special case.
Solhive runs on your PV system's computer (Linux, Docker or Proxmox LXC) and gives you full control over your energy.
Solhive is software you operate yourself — no cloud subscription. Three ways, depending on what you already run:
Lightweight Linux container on your Proxmox host — this is how our pilot systems run today. Lean, protected by snapshots and backups, cleanly separated from the rest of your infrastructure.
For NAS, mini PC or home server: Solhive as a container next to whatever you already run. Configuration and database live in volumes and survive every update.
Straight on Debian or Ubuntu as a systemd service — full control, minimal overhead. Ideal when there is already a machine working next to your PV system.
System requirements — measured on the running pilot
Setup: guided wizard — pick your language, connect your inverter, go. Updates arrive with one click or from your installer.
Using Home Assistant? Solhive deliberately runs as an independent service alongside it and connects your HA devices as a data source — but stays fully functional without HA. A HA add-on is not planned.
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.
One platform, many partner brands.
Each cell is an independent brand.
Solhive is source-available under the PolyForm Perimeter License — and consistently self-hosted: the code does not live with a big-tech platform but on our own Git instance at code.solhive.energy. We treat your system data exactly the same way.
Source access is available to pilots and partners — drop us a line.
No install, no hardware: get your own fully functional Solhive instance for 30 minutes, with a simulated system — two inverters, battery storage, an EV charger and a balcony PV unit.
Create tasks, change settings, watch the controller work in real time.
It runs the same software as in production — so you always see the latest stable release of Solhive with all the newest features; only the devices are simulated.
🐝 Open the live demo →Good to know: 30 minutes per session, after which the instance is reset automatically (changes aren't saved). At busy times there may be a short queue, and some system-critical settings are locked in demo mode.
Are you a solar installer who wants to test Solhive on your customer systems? Or a homeowner who wants to try Solhive for your own PV system?
