Overview
- Retailers rolled out steep, time‑limited discounts this week on 2,000–4,000 W solar module kits bundled with Anker SOLIX 3 or SOLIX 4 Pro storage and Smart Meter Gen2 units.
- Anker’s SOLIX 3 starts at about 2.7 kWh and is expandable to roughly 16 kWh with a 1.2 kW backup rating while the SOLIX 4 Pro begins near 5 kWh, scales toward ~30 kWh with add‑on packs, and offers 2.5 kW via its socket or up to 3.6 kW in bypass mode.
- Bundles routinely include a Smart Meter Gen2 and vendor apps that monitor production and household use in real time so surplus midday power is routed into the battery instead of uncontrolled feed‑in.
- Published calculations and a hands‑on DIY installation showed strong early yields (about 280 kWh in one first month) and projected annual savings of several hundred euros, with typical payback windows of roughly two to six years depending on site and use.
- Buyers should note regulatory and practical limits: inverter feed‑in to the house is commonly capped at 800 W, arrays above typical balkonkraftwerk sizing may trigger full PV registration, and Smart Meter installation often requires an electrician.
