Overview

• Solakon advertises a 2,000 W Quattro set for €449.99 and a bundle with its 2.11 kWh Solakon ONE battery for €989.99, with entry kits starting at €229.99 for 900 W and €279.99 for 1,000 W.
• Price checks show Growatt NEXA 2000 all‑in‑one storage bundles with 2,000 W PV at €925 (ACTEC, plus €129 shipping), €999 (Tepto, plus €149), and €1,039 (Powerness, pickup options to avoid €190 shipping).
• Growatt NOAH 2000 promotions cut the 2.048 kWh battery to €469 with code, while complete sets start at €699 for two panels and €849 for four panels with self‑pickup.
• PC‑WELT highlights a Kleines Kraftwerk package with four 445 W panels and Anker Solarbank 2 E1600 Pro at €1,199 including shipping and a smart meter.
• Background context notes the 2024 Solarpaket 1 raised the inverter threshold to 800 W and allowed 2,000 W module capacity, and independent data indicate batteries lift self‑use but can extend payback (about 3.5 years without storage versus just over 8 years with storage in one measured case).
