New battery nearly doubles capacity of predecessor
The unit supports up to 2,500 W grid-tied output with a Wieland plug and 2,500 W off-grid output. Solar input reaches 5,000 W across four MPPTs, allowing connection of up to 12 solar modules. An expansion battery, the BP5000, adds 5 kWh increments up to 30 kWh. The system includes a display, AI-optimized control, dynamic tariff support, an Anka voice assistant, and open APIs.
The Solarbank 4 E5000 Pro is priced at 1999 EUR (about $2,335). The BP5000 expansion battery costs 1399 EUR (about $1,634). Early-bird buyers can register from May 12 to June 11, 2026, for a 25% discount, with codes redeemable between June 12 and June 21, 2026.
Compared to the Solarbank 3 Pro, the new model offers nearly double the capacity and a 1,400 W increase in solar input. Anker Solix has confirmed the MSRP and early-bird pricing, but has not detailed the exact launch window beyond the redemption period.
