Daily Testing of Balcony Solar Power Plant Equipped with Anchor Solar Bank: Is the Investment Justified?
In a recent development, Kleines Kraftwerk, a provider of innovative Plug & Play solar solutions, has announced the release of the Anker Solarbank 3 Pro. This latest storage generation offers several key improvements and benefits over its predecessor, the Anker Solarbank 2 Pro, making it an attractive option for households seeking to increase self-consumption and save electricity costs.
Jens from Münster, one of the early adopters of Kleines Kraftwerk's technology, installed a Quattro balcony power station with the Anker SOLIX Solarbank 2 Pro in late summer 2024. Since then, Jens' system has been running reliably, working efficiently even in less sunny months. Now, with the upgrade to the Anker Solarbank 3 Pro, Jens and his colleague Sebastian from Kleines Kraftwerk highlight several significant enhancements.
Firstly, the Solarbank 3 Pro boasts a much higher capacity. With a 2688Wh energy storage capacity, it allows for much longer power supply times or more extensive energy storage, a significant upgrade from the Solarbank 2 Pro's capacity.
Secondly, the Solarbank 3 Pro supports up to 3600W of solar input through four independent MPPT (Maximum Power Point Tracking) channels, enabling connection to up to eight solar panels. This enhancement increases charging speed and efficiency compared to the Solarbank 2 Pro.
Thirdly, the Solarbank 3 Pro features a powerful bidirectional inverter, with a 1200W inverter allowing both efficient charging (from solar or grid) and discharging (to power home appliances). This flexibility and usability are an improvement over the 2 Pro’s system.
The Solarbank 3 Pro also benefits from advanced AI optimization. Anker Intelligence™, an AI system, optimizes energy use by analyzing weather forecasts, electricity prices, and consumption habits, resulting in maximized cost savings and efficient energy management compared to the older model.
The Solarbank 3 Pro is also designed for all-weather durability, with an IP65 rating providing protection against dust and water, and an integrated heating function ensuring reliable operation even in temperatures as low as -20°C. This level of durability is an upgrade over the 2 Pro, improving outdoor usability and reliability.
Perhaps most notably, the Solarbank 3 Pro can deliver up to 1200W of emergency power, ensuring continued operation during outages, a significant enhancement in emergency preparedness.
The Quattro complete set with the latest storage generation (Anker Solarbank 3 E2700 Pro) is available for 1,439 euros, while the Anker SOLIX Solarbank 3 Pro storage set with four bifacial modules is available for the same price, including shipping and a free smart meter.
These improvements collectively make the Anker Solarbank 3 Pro a more robust, efficient, and versatile solar storage solution compared to the Solarbank 2 Pro, as emphasized by Jens and Sebastian from Kleines Kraftwerk. The Solarbank 3 Pro is optimal for households that want to increase their self-consumption and save electricity costs without committing to a large system directly. However, it's important to note that legal hurdles may be encountered due to exceeding the 2000 watts allowed for balcony power stations when connecting up to eight solar modules.
