The zero VAT rate under § 12 (3) UStG applies only to deliveries to Germany. Current delivery address: Germany.
Since 1 January 2023 a VAT rate of 0 % applies to certain photovoltaic products.
Up to 30 kWp no proof is required. The conditions are deemed met if the installed gross capacity of the system according to the Marktstammdatenregister does not and will not exceed 30 kilowatts (peak).
If the goods are not bought for a photovoltaic system — for camping, travel or resale, for example — the regular rate applies. Choose 19 % VAT in that case.
Should the conditions not have been met despite your confirmation, the statutory VAT may be charged afterwards.

TheEcoFlow STREAM Ultra is a battery-integrated inverter designed for balcony solar power stations and home energy systems, helping you to generate, store and make smart use of solar energy in your home.
The model is equipped with a 1.92 kWh battery based on LiFePO4 / LFP technology. This type of battery is well suited for daily use, has a long service life and can withstand up to 6,000 cycles whilst retaining up to 70% of its capacity.
The STREAM Ultra supports direct connection of solar panels with a total PV capacity of up to 2,000 W. For this purpose, it features 4 independent MPPT trackers, each rated at 500 W. This allows for efficient operation with multiple groups of solar modules, even if they have different orientations or receive varying amounts of sunlight.
The device connects to a 230 V domestic mains supply and can feed up to 800 W into the home network. An AC output of up to 1200 W is also available for direct powering of devices, whilst the bypass output supports loads of up to 2300 W.
The EcoFlow STREAM Ultra is well suited to modern households looking to reduce their reliance on the mains grid and increase the proportion of solar energy they consume. During the day, the system stores surplus generation and then releases it in the morning, evening or during periods of high demand.
Thanks to Wi-Fi and Bluetooth support, control is available via the EcoFlow App. In the app, you can view the battery status, solar energy generation, consumption and system operation in real time.
The STREAM Ultra integrates into the EcoFlow OASIS ecosystem. Intelligent control helps analyse energy consumption, optimise charging, and distribute energy between the battery, solar panels and home appliances.
The housing has an IP65 rating, making the battery suitable for installation on a balcony, terrace or other sheltered outdoor location. The device operates within a temperature range of -20 to +55 °C and features a battery self-heating function for low-temperature charging.
The storage unit measures 284×255×458 mm and weighs 23.1 kg. The compact vertical housing with a handle is convenient to place near the solar panel connection point or in a utility area.
The EcoFlow STREAM Ultra is the more powerful option in the STREAM range for users who need more solar input. Compared to the STREAM Pro, this model has 4 MPPT inputs instead of 3 and supports up to 2000 W of PV power.
