Overview
- Solakon cut its onLite 900 W starter set to €189 for PV only and €739 with a 2.11 kWh Solakon ONE battery, pairing bifacial panels with app control and a backup outlet.
- High‑spec bundles have fallen too, with Yuma offering a 1,000 W kit plus Anker SOLIX 3 for €1,149 and Kleines Kraftwerk listing a 1,920 Wp set with Anker SOLIX 3 Pro and a free smart meter for €1,377.
- ACTEC Solar promotes immediate stock for a 2,000 W kit with Growatt NEXA 2000 (2.05 kWh) at €999, countering rival lead times of several weeks reported in earlier offers.
- Modern balcony‑PV storages such as Anker SOLIX 3, Solakon ONE and Growatt NEXA integrate the inverter, add multiple MPPT inputs, enable modular expansion, support smart meters and provide notstrom backup.
- Current rules cap inverter feed‑in at 800 W, allow higher panel power if curtailed or stored, and require Marktstammdatenregister registration, while typical 800 W systems yield about 600–750 kWh a year and can pay back in roughly 2–4 years, with 2–3 kWh batteries raising self‑use toward 70–90%.
