Anker SOLIX Solarbank 3 E2700 Pro Set

The effective use of solar power often fails with standard balcony power plants due to unsuitable storage sizes: Either the battery is too small to cover the base load overnight, or the system is so large that two modules can hardly fill it in everyday use. Anker fills this gap with the Solarbank 3 E2700 Pro Set. Paired with two high-end modules, this configuration offers a perfectly balanced ratio of generation and capacity that can flexibly grow into a full-fledged system as needed.

Classification and target audience

In the market for plug-and-play solar systems, this complete set is positioned in the higher, smart mid-range. Those who read current expert reports will recognize the primary target audience: renters with traditional balconies, homeowners, and smaller households aiming for a noticeable reduction in their electricity base load. The system is optimized for those looking for a compact plug-and-play setup with an integrated inverter while keeping all options for future system expansion open.

Individuals expecting a three-phase emergency power feed for an entire single-family home without installing additional components are more likely to opt for the manufacturer's larger systems.

Technical features and advantages

The heart of the system: The storage and inverter unit

The functional center is the Solarbank 3 E2700 Pro. It combines battery chemistry and the adjustable 800-watt inverter (often upgradeable to 1200 watts via software update) in a sleek housing, minimizing installation effort.

• Optimized 2.7 kWh base capacity: The storage is based on durable lithium iron phosphate cells (LiFePO4) and provides a net capacity of 2.7 kilowatt-hours. This sizing is perfectly sufficient to autonomously cover the typical base load of an apartment (approximately 150 to 300 watts) throughout the evening and night hours.
• Weatherproof according to IP65: The housing is completely dust and jet water protected, allowing for easy placement on an uncovered balcony or terrace.

The power plants: The RS50S solar modules

To reliably fill the 2.7 kWh capacity on sunny days, Anker provides two RS50S ultra-solar modules in this set.

• 1.0 kWp total power in the set: Each module delivers exactly 500 watt-peak (Wp), resulting in a PV input power of 1,000 watts in tandem. This optimally exploits the legal limit for balcony power plant components.
• Bifacial N-Type TopCon technology: The modules use highly efficient N-Type cells, which excel in weak light performance on cloudy days. The bifacial design also utilizes reflected light on the back (e.g., from building walls), which can increase actual yield by up to 20%.
• Robust double-glass design: The mechanically extremely resilient glass-glass construction in an elegant full black design permanently protects the cells from hail and strong winds.

Enormous scalability: The expansion options

Although the set starts as a compact all-in-one solution for standard balconies, Anker breaks the boundaries of rigid systems here. The E2700 Pro Set is fully modular and can be significantly expanded in two directions:

1. The battery level (storage expansion)

If your electricity needs during the evening and night hours increase over time – for example, due to the acquisition of new continuous consumers, an air conditioner, or an e-bike – the capacity of the E2700 Pro can be flexibly expanded.

• Modular plug system: Additional stackable batteries from the Anker-SOLIX ecosystem can gradually expand the base capacity of 2.7 kWh.
• Tool-free assembly: The expansion batteries are simply placed under or over the main unit and connected mechanically and electrically via a robust, weatherproof plug system. No complicated screwing or manual wiring is necessary.

2. The PV input side (module expansion)

The set is delivered as standard with two 500W RS50S modules. To charge the storage more quickly and reliably, especially during transitional periods (spring and autumn) or on heavily cloudy days, the generation capacity can be increased.

• Connection of additional modules: The Solarbank 3 E2700 Pro supports connecting additional solar modules via optional expansion hubs or Y-adapters.
• Maximum utilization: You can supplement the system with additional panels (e.g., for optimized east-west orientation). This way, you capture light early in the morning and late in the evening to fully exploit the legal and technical limits of the PV input power.

Weaknesses and compromises

Despite the excellent balance spectrum, the focus on two modules in the delivery state brings conceptual limitations. Since the set only comes with two RS50S panels from the factory, it may occur during the sun-poor and short winter months that the generated energy is insufficient to fully charge the relatively large 2.7 kWh storage during the day. Those who want to utilize the full capacity even in winter are almost forced to take advantage of the aforementioned module expansion.

Additionally, the 500W modules are physically noticeably larger and heavier than older 400W standard modules due to their high power. Mounting on a delicate balcony railing therefore requires stable, approved mounting accessories and craftsmanship. As with all smart systems from the manufacturer, the second-accurate feed-in control via the Anker app (including coupling with smart plugs) also requires a permanent and stable Wi-Fi signal at the storage's installation location.

Conclusion & purchase recommendation

The Anker SOLIX Solarbank 3 E2700 Pro Set with 2 RS50S offers the currently most balanced ratio of generation and storage capacity for urban households. The price-performance ratio is excellent, as you receive a state-of-the-art all-in-one system without hidden additional costs or cable clutter.

Those looking to purchase the Anker SOLIX E2700 Pro Set are investing in a highly efficient, visually appealing system to reduce their electricity bill. Anyone seeking a smart balcony power plant recommendation that provides sufficient storage for the night, does not take up too much space in everyday life, but can be expanded into a full-fledged solar system if needed, will find the most flexible solution currently available on the market here.
