Private label with system expertise for specialist retailers, integrators, and project customers
WATTSTUNDE® stands for well-engineered solar technology, profound technical expertise, and reliable solutions for self-sufficient power supply. As a private label with a clear B2B focus, we have been developing products and systems for mobile and stationary applications since 2014 – from motorhomes and off-grid systems to garden sheds, cabins, and complex project solutions.
Our ambition goes beyond mere product distribution: we think in systems, not in individual components. WATTSTUNDE® combines high-quality solar technology with comprehensive consulting expertise – for solutions that are technically convincing and economically viable.
Solar technology from WATTSTUNDE® – developed for practical use, performance, and durability
WATTSTUNDE® products are developed with the goal of being technically mature, reliable, and easy to integrate. The focus is on clear functionality, reduced design, and stable performance – even under challenging conditions such as limited installation space, changing weather conditions, or mobile use scenarios.
Whether as a complete system or for expanding existing installations: WATTSTUNDE® solar technology is designed systemically, is modularly scalable, and is economically viable in the long term.
Self-sufficient energy systems from a single source – the WATTSTUNDE® product range
Solar modules for mobile and stationary applications
WATTSTUNDE® solar modules cover various mounting and application requirements:
- SOLA Frame – framed, particularly stable modules for fixed mounting and durable installations
- SOLA Flex – semi-flexible modules for uneven surfaces, low weight, and low-mounting applications
- SOLA Ease – foldable solar bags for maximum flexibility, optimal alignment, and mobile use
All module variants are designed for high efficiency, robust construction, and long service life.
Solar charge controllers (MPPT & PWM)
For safe and efficient energy management, WATTSTUNDE® offers suitable charge controllers:
- MPPT charge controllers like the TARA Flow for maximum energy yield and modern battery systems
- PWM controllers for compact, cost-effective applications
The controllers ensure stable charging processes and reliably protect batteries from incorrect loading.
Batteries & Energy Storage
WATTSTUNDE® offers powerful storage solutions for self-sufficient systems:
- NOVA Base LiFePO₄ (20 Ah – 200 Ah) – compact, lightweight, and ideal for modular systems
- NOVA Core LiFePO₄ (100 Ah – 480 Ah) – with integrated heating mat for demanding applications and cold environments
- NOVA Lead AGM – proven solution for classic applications
All battery systems are designed for high cycle stability, safety, and flexible expandability.
Inverters for self-sufficient power supply
WATTSTUNDE® inverters provide stable 230 V power for sensitive and high-power consumers:
- TARA Sync – compact sine wave inverter (800 W – 2200 W) for mobile and stationary applications
- TwinPeak – combined off-grid inverter with integrated MPPT controller and charger for stationary off-grid systems
Pure sine wave voltage, high efficiency, and well-designed protection mechanisms ensure safe operation.
Mounts, Cables & Accessories
WATTSTUNDE MOUNT mounts, high-quality solar cables, adapters, and mounting materials enable clean and professional installation – tailored to practical requirements.
Why WATTSTUNDE® is the right choice for B2B customers
System thinking instead of individual products
