SolarAssistant is real-time solar monitoring and control software that runs on a Raspberry Pi. It is positioned as an alternative to expensive or poorly designed dedicated monitoring devices. You can view live metrics via the web, Android, or iPhone; the site states that data can refresh as quickly as around 2 seconds. It can also operate as a standalone system without internet access, while remote access over the internet is available when you are away.
Feature-wise, it covers solar monitoring, historical data, charts, totals, exports, backups, user management, and automation rules. For installers, a particularly valuable feature is the ability to adjust inverter settings remotely, reducing the cost of on-site visits. On the permissions side, it supports single sign-on, multi-site access, and inviting an unlimited number of users with either read-only or administrator privileges.
Compatibility is a key point to verify before use. The page lists support for multiple inverter brands, including Axpert, Growatt, EG4, Deye, Kodak, SunSynk, MPP Solar, Sol-Ark, and Voltronic, while also noting that many devices may be rebranded Voltronic or Deye units. It explicitly states that ABB, Enphase, Fronius, SMA, SolarEdge, Solax, FOXESS, and others are not supported. In terms of ecosystem integration, it supports Home Assistant auto-discovery, MQTT, and custom project integrations, and provides documentation entry points for REST API, WebSocket API, Cloud API, command-line interface, and Node-RED.
The captured text includes links to a Shop and pro forma invoice generation, but does not disclose specific pricing, plans, license periods, or payment methods. For deployment, SolarAssistant emphasizes Raspberry Pi usage and local standalone operation, which is practical for off-grid, unreliable-network, or cloud-averse solar setups.
Its strengths are low hardware cost, local availability, strong real-time performance, remote operations and maintenance, and solid Home Assistant/MQTT integration. The documentation structure is also fairly comprehensive, covering getting started, hardware, inverters, batteries, APIs, troubleshooting, and more. The downsides are that pricing is not transparent and the open-source status is not stated. Device compatibility limitations are significant, and remotely changing solar equipment settings carries safety risks; the official guidance also indicates that this should be handled by qualified installers. It is a good fit for residential solar users, off-grid system users, solar installers, and technical users who need Home Assistant automation.
The text does not provide information about access from mainland China, payment, local agents, or Chinese-language support, so these remain unknown. If access from China is unstable, alternatives such as manufacturer-provided monitoring tools, WatchPower, ICC, or the Home Assistant energy dashboard may be worth considering, but compatibility and real-time control capabilities need to be verified case by case.
