Overview

• A Chip.de report on a Bremen family using an EcoFlow Stream Ultra X with four PV panels found some weeks where grid draw fell below 20%, driven by timing appliances to match solar output.
• Adding a smart meter enabled more precise load management in the test, which further reduced reliance on the grid according to the tester’s data.
• Homeandsmart highlights Maxxisun’s new Maxxicharge V2 control unit with an integrated inverter that manages charging, discharging and zero‑export operation for balcony PV setups.
• The manufacturer claims V2 supports emergency power via a built‑in outlet (up to 1,200 W continuous, 1,800 W short) and offers uninterrupted backup when hard‑wired with a transfer switch.
• Maxxicharge batteries come in 3 kWh or 5 kWh modules scalable up to about 49 kWh or 83 kWh, with up to 2,000–3,000 W PV input per unit, and a vendor example lists a 2,000 W kit with 5 kWh storage and smart meter at roughly €2,800, with most performance assertions sourced from the company.
