Detailed overview: Zendure SolarFlow 1600 AC+ AC-coupled balcony solar battery
The Zendure SolarFlow 1600 AC+ is the entry-level variant of the new SolarFlow range, built to complement a balcony solar setup already fitted with a PV inverter, without going through direct solar regulation. Unlike the SolarFlow 2400 Pro, which packs 4 MPPT controllers, the 1600 AC+ connects purely over AC, making it 100% compatible with rooftop PV inverters already installed, regardless of brand.
Its 1920 Wh LiFePO4 battery exchanges up to 1600 W of bidirectional AC power, enough to cover most of a household's electrical needs. Its on-grid and off-grid ports ensure uninterrupted power during a grid outage, and its capacity extends up to 11.52 kWh by adding AB2000L expansion batteries.
IP65 rated and backed by a 10-year warranty, it is controlled through the Zendure app over Wi-Fi and Bluetooth, with the same tariff intelligence as the rest of the SolarFlow range: charge and discharge optimisation based on compatible European energy providers.
The SolarFlow 1600 AC+ is aimed specifically at anyone who already has a working balcony solar setup and wants to add storage at the best price, without rethinking the solar electronics already in place.

Comparison
How does the Zendure SolarFlow 1600 AC+ compare with other AC-coupled balcony solar batteries, for searches like "solar battery compatible with existing inverter"? Here is how it stacks up against two references already in the catalogue: the Zendure AB2000L and the EcoFlow Stream AC Pro.
| Criterion | SolarFlow 1600 AC+ | Zendure AB2000L | EcoFlow Stream AC Pro |
|---|---|---|---|
| Capacity | 1920 Wh | 1920 Wh | 1920 Wh |
| AC output | 1600 W bidirectional | 800 W grid | 1200 W (2300 W with two units) |
| Backup power | Yes, on-grid/off-grid | No | Yes, up to 1200 W |
| Expandable | 11.52 kWh | Up to 17.28 kWh | 11.52 kWh |
| Observed price | ≈ €719 | ≈ £512 | ≈ £699 |
In short, the SolarFlow 1600 AC+ stands out for the highest output power in this comparison (1600 W) and its built-in backup function. The Zendure AB2000L stays cheaper but needs a separate hub to work, while the Stream AC Pro offers comparable power with the option of pairing two units. For anyone who wants to add powerful storage to an existing setup without an extra hub, the SolarFlow 1600 AC+ is a coherent choice.

Our tester's review: Julien De Jurquet
The SolarFlow 1600 AC+ plays the simplicity and price card: no MPPT to manage, no panels to wire directly, you connect it over AC to a solar setup already fitted with an inverter, and it stores the surplus to release it later. The 1600 W bidirectional power covers most everyday needs, and the on-grid/off-grid ports with uninterrupted power are a real plus during an outage. For anyone who already has working panels and an inverter and just wants to add storage without rethinking the setup, this is a direct solution, notably cheaper than models with built-in MPPT. Our one reservation: with no direct solar input, it depends entirely on an existing setup, so it is not a starting point for anyone with no panels yet. For that specific use case, the price-to-simplicity ratio is excellent.
