Anker Unveils SOLIX 4 as High‑Input, Modular Home Battery

Overview

• Anker announced the SOLIX Solarbank 4 E5000 Pro on Saturday, June 20, 2026, as a 5 kWh base unit that can be expanded modularly to 30 kWh DIY or to 120 kWh with a Power Dock.
• The company says the SOLIX 4 has four MPPT inputs for up to 5,000 W of solar charging and separate outputs of 800 W grid‑coupled plus 2,500 W off‑grid that can run in parallel to supply about 3,600 W; these longevity and savings figures are manufacturer claims that lack independent long‑term validation.
• EcoFlow’s STREAM Ultra X remains the main established alternative with a 3.84 kWh base, up to 2,000 W solar input, and two AC sockets delivering up to 2,300 W for heavy appliances.
• Retailers are cutting prices on earlier SOLIX generations and selling bundled sets, for example SOLIX 3 offers reported around €999 and SOLIX 2 Quattro packs advertised near €977, which creates value opportunities for buyers who do not need the new top‑tier specs.
• Practical buying factors still hinge on module choice, installation and registration costs, and expected payback; modules are the largest cost driver, starter storage sets begin around €800, and a yearlong field test showed a 960 Wp starter kit can amortize in about two years under favorable conditions.
