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.
Text of the law: § 12 (3) UStG. We do not provide tax advice — if in doubt, please consult your tax adviser.

EcoFlow Delta Pro 3 – the most portable solar home battery.
Reliable power for every moment.

Seamless emergency power supply for the whole house.
The EcoFlow DELTA Pro 3 can be integrated into your home’s electrical circuits via the EcoFlow Smart Home Panel 2 or a transfer switch (installation by a qualified electrician). Switch seamlessly between mains and battery power, reduce your electricity bills or stay powered up during power cuts. Everything keeps running – from the fridge to the Wi-Fi – even when the mains go down.

Expandable capacity for longer runtime and greater savings.
With up to two additional batteries, you can expand the capacity to up to 12 kWh. Run appliances for longer, store more solar power and reduce your electricity bills.
Quiet comfort for your family and neighbours
Thanks to X-Quiet technology, the system operates at just 30 dB when the load is below 2,000 W – so quiet that it’s barely noticeable even right next to your bed.
Seamless emergency power supply. Protect your data and devices with a lightning-fast switchover in just 10 ms. NAS systems, servers and entertainment electronics continue to run reliably even during power cuts.
6 flexible charging methods – anytime, anywhere.


With EcoFlow’s groundbreaking X-Stream fast-charging technology, you’re setting a new industry standard: from 0 to 80 per cent in just 1 hour. With multiple charging combinations, you can charge at super-fast speeds of up to 7,000 W.
State-of-the-art LFP technology.
The EcoFlow DELTA Pro 3 is equipped with automotive-grade LFP cells and features an IP65-certified battery pack (the first of its kind in the industry, according to EcoFlow) – protected against impacts, water, dust and fire. After 4,000 charge cycles, it still retains 80 per cent of its original capacity, which equates to around 11 years of daily use. This means you can rely on your power station in any situation and in all weathers.
Simple all-in-one control via the EcoFlow app.
