Overview

• ACTEC is advertising a Growatt NEXA 2000 package with four 505 W Trina modules (2,020 Wp) for €1,211 plus €129 shipping, including a 2.048 kWh LiFePO4 storage unit with four MPPTs, Time‑of‑Use charging and IP66 weather protection.
• PC‑WELT highlights Kleines Kraftwerk’s Quattro bundle at €1,359 delivered, pairing four 450 W bifacial TOPCon panels with Anker’s Solix Solarbank 3 E2700 Pro, a free smart meter and optional statically tested mounts for €199.
• Chip.de notes Solakon’s onPower set with four 500 Wp JA Solar modules and an APSystems EZ1 inverter at about €480 headline price, though mounts and shipping raise the effective outlay to roughly €800.
• The APSystems EZ1 inverter in the Solakon set is limited to Germany’s permitted 800 W output under Solarpaket 1, aligning the larger panel arrays with current plug‑and‑play rules.
• Performance claims for bifacial/TOPCon modules vary across coverage, with Chip.de citing a realistic 5–10% yield gain versus vendor‑level assertions reported by PC‑WELT of up to roughly 30–38% in favorable conditions.
