What we offer
Four core solutions, countless energy challenges solved. Choose yours—or let us build something new for your grid.
Craftum_ Pulse
Monitor solar production, battery health, and energy usage in real time. No more spreadsheets—just clean dashboards with actionable data. Compatible with all major inverter APIs (SMA, SolarEdge, Huawei, OCPP, REST, GraphQL). Our solar monitoring dashboard for photovoltaic systems of any size: From single PV installations to complete solar parks. For solar companies: centralized monitoring of all customer installations with automatic error notifications. For utilities and energy providers: multi-tenant platform with white-label option and API integration into existing systems.

Need something unique, scalable, or beautifully simple? We design and build software that fits your energy business—API-first, cloud-native, and ready for the future. From initial concept to production system: We analyze your requirements, design lean architectures, and implement them with modern technologies. Whether energy management systems for utilities, customer portals for solar companies, or backend infrastructure for IoT devices—with TypeScript, Next.js, NestJS, and PostgreSQL, we build performant, maintainable systems. Cloud-native deployment, CI/CD pipelines, and automated testing are standard.
Energy Community Enablement
Turn your solar surplus into shared value. We enable neighborhoods, companies, and communities to share energy and manage consumption like a true digital grid. Energy communities are the future of decentralized power supply: Those who produce solar power share it with neighbors, tenants, or businesses—transparently, legally compliant, and automated. Our platform handles billing logic, tracks feed-ins in real time, and generates monthly reports. For housing associations and utilities: white-label solution with tenant management, smart meter connectivity, and dynamic tariffs.
Smart Automation Solutions
From internal workflows to customer-facing processes—we build bots, integrations, and logic that automate routine tasks and optimize energy management. We automate workflows across the energy value chain: from system planning through installation to billing. Chatbots for customer service, AI-powered data validation, automatic reporting. Our multilingual communication bot for installation teams translates voice messages in real time. ERP integrations connect accounting, CRM, and project management with API gateways to smart meter infrastructure and inverters.
What we use to build
Representative but not exhaustive list
Frontend
Modern web technologies (React, Next.js, TypeScript) power high-performance, SEO‑friendly, responsive user interfaces. We implement component-based architectures, server-side rendering (SSR) for fast Time to First Paint (TTFP), code-splitting, accessibility best practices and optimized client‑side hydration to ensure top UX and crawler visibility.
Backend
Robust, scalable server‑side architecture (Node.js, NestJS, GraphQL, PostgreSQL) for secure, real‑time energy data ingestion, processing and IoT integration. We leverage API‑first design, microservices, token‑based authentication and automatic scaling—perfect for smart grid, utility platforms and compliance requirements.
Cloud Infrastructure
Scalable, sustainable cloud solutions (AWS, Azure, Hetzner) with 99.9% uptime and carbon‑neutral hosting for energy platforms. We use Infrastructure‑as‑Code (Terraform), CI/CD pipelines, container orchestration (Kubernetes), monitoring (Prometheus, Grafana), and autoscaling to ensure performance, security, cost-efficiency and environmental sustainability.
Development Tools
Seamless dev workflow with GitHub, Docker, CI/CD and automated testing for efficient, collaborative software delivery. We enforce code reviews, static analysis, continuous delivery and performance testing—supporting fast, reliable releases and mission‑critical quality for energy and utility software.

Craftum Pulse is a powerful solar monitoring dashboard for photovoltaic systems. It enables real-time access to all relevant data of your PV system – from current solar yields to energy consumption, battery status and CO₂ savings. Compatible with common inverter APIs (SMA, SolarEdge, Huawei), it offers a central, secure platform for PV monitoring, energy management and optimization.
Our multilingual communication bot for solar projects uses AI, speech recognition and automatic translation to transcribe voice messages from installers in real-time and translate them into different languages. This way, status updates, technical notes and project information reach all stakeholders without delay.
An energy community is a local network where participants share self-generated solar power. Excess energy is fed into the community grid, other members can use this power when needed. With our Craftum platform, the energy community becomes legally compliant and transparent: automatic billing, energy monitoring and digital management.
Our tech stack is designed for scalability and security. In the frontend we use Next.js, in the backend NestJS. We store data with PostgreSQL, deployment via Docker. This architecture enables seamless integration with IoT devices, smart meters and external energy platforms.
Yes – Craftum Pulse is deliberately developed so that it can be used by both PV professionals and beginners without problems. The user interface is intuitive, mobile-friendly with integrated help and step-by-step instructions.
Security is our top priority. We use industry-standard encryption, secure authentication methods, and follow best practices for data protection. Our infrastructure is hosted on reliable cloud providers with 99.9% uptime and regular security audits.
Absolutely. We specialize in API-first architecture and have experience integrating with various energy platforms, IoT devices, smart meters, ERP systems, and CRM tools. We'll work with you to ensure seamless integration with your existing infrastructure.
