Zendure SolarFlow Hyper 2000: Specs and Tariff Stacking

The Zendure SolarFlow Hyper 2000 is a plug-in, AC-coupled battery unit that stores solar or off-peak grid electricity and pushes it back into the home through a standard socket. Zendure describes it as "the world's first multi-sets coordination plug-in solar system with bidirectional AC-coupled storage solution"¹. Each unit delivers 1,200W of bidirectional AC power, accepts up to 2,400W of solar input through an 1,800W MPPT, and stacks with AB1000 and AB2000 batteries².

The headline numbers are the ones a householder will search for. A single Hyper 2000 takes a stack of four batteries, with a maximum total capacity of 7,680Wh². Three units on the same phase reach 23.04kWh of storage, and Zendure states that battery capacity across the range runs from 0.96kWh to 23.04kWh³. The unit is IP65 rated, weighs approximately 8.5kg excluding accessories, and measures 350 x 202 x 78mm².

What the Hyper 2000 does for independence is real but bounded. It shifts when a home draws from the grid, and it can keep essential appliances running in off-grid mode, but it does not take a household off the grid, off a supplier, or off the gas network. It also introduces a dependence on Zendure's app, its servers and a Wi-Fi connection for anything beyond local control. This page sets out the specifications, the warranty position, the pricing picture and the company's status, and links to the wider plug-in battery storage and home battery storage guides where the rules and alternatives are covered.

What the Hyper 2000 offers a UK household

The Hyper 2000 is a plug-in system, which is the point of it. Zendure states that installation takes three minutes without altering existing wiring, and that the unit is AC-coupled and plug-and-play, avoiding complex rewiring⁴. It is designed for balconies, workshops, gardens and most outdoor environments, and the IP65 rating supports that².

The architecture is what separates it from a conventional home battery. Rather than a single inverter wired into the consumer unit, the Hyper 2000 uses hybrid microinverters and a 48V platform, which Zendure states reduces energy loss by 25% compared to a 16V platform². It has four sets of solar connectors and can connect up to four groups of solar panels, with dual MPPTs that Zendure says suit most installation conditions and can increase efficiency².

Phase handling matters in a UK context. Zendure states that when Hyper units sit on different phases, each works independently and can reach its full 1,200W capacity, while units on the same phase automatically network and unify their total output to 0 to 1,800W². The multi-unit power limit for a ZenLink setup is stated as 3,000W⁷. For a household on a single-phase supply, which is the common UK arrangement, the same-phase behaviour is the one that applies.

The unit also supports bidirectional charging, meaning it can be charged both from solar panels and from the electricity grid⁴. That is the feature that makes tariff stacking possible rather than solar-only operation, and it is covered in more detail below.

Specifications: 1,200W AC, 1,800W MPPT, 48V platform

The table below sets out the figures Zendure publishes for the Hyper 2000. Where a figure applies to a bundle rather than the bare unit, the bundle is named.

Two limits are worth stating plainly. Zendure warns that the open circuit voltage on each MPPT input must be lower than 55V, and that panels above 55V may cause permanent damage². Where panels are small, between 100W and 350W, Zendure states that two or three can be connected in parallel on a single set of solar connectors, provided the Voc stays between 15V and 55V². The battery chemistry is LiFePO₄, and the AB2000 and AB2000S each hold 1,920Wh with operation down to minus 20 degrees C⁴. Below 0 degrees C outdoors, Zendure recommends only the AB2000, or siting the system indoors above 0 degrees C².

Warranty: 10 years claimed, 5 years in the policy

The warranty position is the weakest part of the Hyper 2000's published record, because Zendure's own documents disagree. Product and sales pages state a 10-year warranty and a 15-year product lifetime for the Hyper 2000². The company's warranty policy page, which carries an effective date of 12 December 2023, lists the Hyper 2000 at 5 years for the EU and Switzerland⁵.

The same policy page shows how much the terms vary across the range. The SolarFlow 800 is listed at 12 years, the SolarFlow 800 Pro and 800 Plus at 10 years, and the SolarFlow 2400 AC, SolarFlow 1600 and SolarFlow 2400 Pro at 3 years⁵. Other Zendure pages state a 10-year warranty and 15 years of use for the SolarFlow battery with up to 6,000 cycles⁹. The Hyper 2000's own product page repeats the 15-year lifetime claim².

What the warranty covers is not set out in the material available: no retained capacity threshold, throughput limit or cycle count is stated for the Hyper 2000 specifically. For how these terms are usually structured across the market, and what to check before relying on a headline figure, see home battery warranties.

Tariff stacking and time-of-use operation

The Hyper 2000's grid charging capability is what makes it a tariff-stacking device rather than a solar-only one. Zendure states that the unit can charge its batteries using home AC power, that charging can be scheduled during off-peak hours, and that it charges automatically from AC when the batteries are low². Multi-unit ZenLink setups on the same phase charge at 1,200W to 1,800W⁷.

Zendure markets this as advanced cost optimisation through time-of-use tariffs, and the Hyper 2000's price lists describe the same feature⁷. The company also publishes guidance on time-of-use operation¹⁰. The logic is straightforward: charge when electricity is cheap, discharge when it is expensive, and let solar top up in between.

Two operational details shape how well that works. First, the Smart CT mode: Zendure states that the Hyper 2000 automatically switches to charging mode when it detects that solar production exceeds 80W for one minute, with a 50W safety buffer, and that this requires Hyper 2000 Master firmware V2.1.18 or higher². Second, the reserve behaviour: when the batteries are nearly depleted, the unit uses AC and/or solar power to keep them at 5%, and otherwise enters sleep mode².

The unit supports Shelly Pro 3EM, Shelly 3EM, Zendure Satellite Monitor CT, Zendure Satellite Plug and Shelly Plus Plug S for metering and control². Zendure states that the Hyper 2000 pairs with a Shelly Pro 3EM through local communication without relying on the internet². That matters for the independence question, because it means the core control loop can run without a cloud service. For how these arrangements compare across the market, see stacking a home battery with smart and time-of-use tariffs.

What the Hyper 2000 costs

Zendure does not publish a standalone UK price for the Hyper 2000 in the material available. Bundle prices on its store are recorded in Shopify price units rather than as stated GBP figures, so they cannot be read as confirmed retail prices¹¹.

Availability is also uneven across the range. The SolarFlow 800 Pro is listed as sold out, with Zendure pointing buyers to the SolarFlow 800 Pro 2 as an alternative¹². The Hub 2000 balcony power plant page carries an inventory flag showing available false for the variants shown, even while the page states 100% in stock and dispatch in 3 to 5 days¹¹. Stock should be checked at the point of order rather than assumed from a banner.

Company status and UK availability

Zendure sells through a UK storefront alongside its main site, and the Hyper 2000 appears across its UK-facing product and pricing pages¹³. The company is trading and shipping, and its product catalogue continues to be updated: the AB3000L battery listing was created on 5 February 2026, and the SolarFlow 2400 Pro base variant carries a created and updated timestamp of 27 April 2026¹⁵.

The Hyper 2000 is described as a new release on Zendure's home energy page⁶. It is compatible with the AB2000L battery, which Zendure states works only with the SolarFlow 1600 AC+, SolarFlow Hyper 2000, SolarFlow Hub 2000, SolarFlow 800 and ACE 1500¹³. The wider SolarFlow range includes the Mix series, the 4000 Mix AC and the balcony solar system sets¹⁶.

On certification, Zendure states that the Hyper 2000 has obtained VDE-AR-N 4105 certification for Germany and VFR 2019 certification for France, allowing direct plug-in to standard household sockets in those markets². No equivalent UK certification is stated. That distinction matters: German and French approvals for plug-in operation do not carry across to the UK, where the rules for connecting storage are set differently. For the UK position on plug-in units, see plug-in and balcony battery storage in the UK and are plug-in batteries safe for UK homes.

Zendure also states that no VAT is payable on the Hyper 2000 under Section 12 of the German Value Added Tax Act². That is a German tax position and does not describe UK VAT treatment.

What it means for household energy independence

The Hyper 2000 shifts a household's relationship with the grid in three ways. It lets solar generation be stored and used later rather than exported at a low rate. It lets cheap off-peak electricity be bought and discharged during expensive periods. And in off-grid mode, Zendure states that it provides backup power for essential household appliances, with a 20ms UPS switchover for devices on standby⁷.

What remains is substantial. The unit does not disconnect a home from the grid, and it does not remove the need for a supplier. It draws from the grid whenever it charges from AC, which is the basis of its tariff-stacking function. Its solar input depends on panels being sited and connected, and its output is limited to 1,200W per unit, or 1,800W unified across units on the same phase². A household with high simultaneous demand will still draw from the grid.

The dependence on Zendure as a company is the other side of it. Local control is genuinely local in places: the Shelly Pro 3EM pairing runs without the internet, and units communicate over ZenLink without Wi-Fi². But remote monitoring, scheduling from away and firmware updates run through Wi-Fi at 2.4GHz or 5GHz, Bluetooth, and Zendure's own app and servers². The SolarFlow 800 is described as running on the ZEN+OS control system with reliability even without internet, which suggests the direction of travel, but the Hyper 2000's remote features remain tied to the manufacturer's platform¹⁹.
