Overview
- Retailers this week are advertising steeply discounted 2 kW+ plug‑in PV bundles that combine Anker SOLIX 4 or SOLIX 3 storage with four 500 W modules and a Smart Meter Gen 2 at prices from about €1,300 to under €1,800.
- Anker’s SOLIX Solarbank 4 Pro is a modular 5 kWh LiFePO4 home battery with up to 5,000 W PV input, four independent MPPT inputs, expandability to roughly 30 kWh, an IP66 rating, and a rapid notstrom output of about 2,500 W.
- Multiple analyses warn that pairing a 5 kWh battery with only 2 kW of modules often leaves capacity unused and recommend roughly 4 kW of PV to better fill the SOLIX 4 and raise annual yield and payback speed.
- Lower‑cost, in‑stock alternatives such as the Growatt NEXA 2000 offer 2.048 kWh LiFePO4 storage, integrated inverter, IP66 protection and complete kits from about €890 for buyers prioritizing price and immediate delivery.
- Smart Meter Gen 2 inclusion is a common selling point because second‑accurate metering and load steering prevent unneeded grid exports and can raise self‑consumption from roughly 25–35% without storage to as much as 80%, improving household economics.
