Detailed overview: Zendure 8 kWh home battery with dual high-voltage MPPT and third-party inverter input
The Zendure SolarFlow 4000 Mix Pro is the most complete model in the new SolarFlow Mix range, which merges high-power home storage, the simplicity of balcony systems and the flexibility of a mobile station. It targets households of around 4 people, with an annual consumption around 7000 kWh.
Its distinguishing feature versus the SolarFlow 4000 Mix AC+: a dual high-voltage MPPT controller (30 to 400V DC, 8000W total) that allows direct connection of new solar arrays wired in series, reducing the need for additional inverters on a new installation. It also keeps the dedicated 5000W input that accepts the output of an existing third-party PV inverter (Huawei, SMA, Fronius, Enphase, SolarEdge, Sungrow and most other brands according to Zendure), for retrofit projects. Combined, these two inputs reach up to 13000W of total solar input, a rare figure in this segment.
Its native capacity of 8000 watt-hours in lithium iron phosphate extends up to 50 kWh by adding modules. Bidirectional power reaches 4000 watts on charge and discharge, boosted to 5000 watts in PV bypass mode. Stated round-trip efficiency is 90%, and the unit is rated for 10000 cycles down to 70% remaining capacity, roughly 15 years of service based on two full cycles a day, backed by a 10-year manufacturer warranty.
During a power cut, an off-grid output delivers 3680 watts continuously and up to 7200 watts at peak, with an automatic 10 ms switchover. The IP65-rated metal enclosure operates from -20 to +55°C, with a stated noise level of around 25 dB at half load (up to 40 dB at full power). Control runs through HEMS 2.0 and the ZenKi 2.0 AI, with LAN, RS485, Wi-Fi and Bluetooth communication, plus Home Assistant and Homey compatibility for advanced users. At the time of writing, the dedicated UK listing shows as sold out. For a lighter setup without a direct MPPT need, the SolarFlow 4000 Mix AC+ remains a cheaper alternative.

Comparison
How does the Zendure SolarFlow 4000 Mix Pro compare with other high-capacity home batteries, for searches like "best home solar battery dual MPPT"? Here is how it stacks up against two references already in the catalogue: its smaller sibling the SolarFlow 4000 Mix AC+, and the Bluetti Balco 500, another recently announced high-end battery.
| Criterion | SolarFlow 4000 Mix Pro | SolarFlow 4000 Mix AC+ | Bluetti Balco 500 |
|---|---|---|---|
| Starting capacity | 8000 Wh | 8000 Wh | 5024 Wh |
| Total solar input | 13,000 W (MPPT + third-party inverter) | 5000 W (inverter only) | 4300 W (1 high-voltage MPPT) |
| Direct MPPT built in | Yes, dual MPPT 8 kW | No | Yes, 1 MPPT |
| Bidirectional power | 4000 W (5000 W in bypass) | 4000 W (5000 W in bypass) | 3680 W |
| Observed price | £2899 | £2399 | ≈ £1599 |
In short, the SolarFlow 4000 Mix Pro stands out for its unique ability to combine direct MPPT and a third-party inverter input, giving it the highest total solar input in this comparison. The Mix AC+ remains a more affordable option for anyone who already has an inverter in place and does not need direct MPPT, while the Balco 500 offers a lower entry price but with more modest capacity and solar input. For an ambitious new installation or a retrofit with panel expansion, the Mix Pro is the most complete option on paper.

Our tester's review: Julien De Jurquet
The SolarFlow 4000 Mix Pro sets itself apart from its smaller sibling, the 4000 Mix AC+, with a genuine technical edge: its dual high-voltage MPPT controller (30-400V, 8 kW) allows direct connection of new panels without relying on a third-party PV inverter. Combined with the dedicated 5000W input for an existing inverter, it can pool up to 13 kW of solar input, a rare figure in this segment of modular home batteries. On paper, the 10 ms switchover to off-grid output and the 7200-watt peak leave good headroom for high-inrush appliances like a heat pump. Our main reservation at this stage concerns availability: the UK-specific listing currently shows as sold out, a point worth checking directly before ordering. For an ambitious new solar installation or a high-consumption household, it remains the most complete option in the Mix range on paper.
Frequently asked questions: Zendure 8 kWh home battery with dual high-voltage MPPT and third-party inverter input
The Mix Pro additionally integrates a dual high-voltage MPPT controller (8 kW), allowing direct connection of new solar panels without relying on a third-party inverter. The Mix AC+ is limited to the dedicated input for an existing PV inverter. Combined, the Mix Pro's two inputs reach up to 13 kW versus 5 kW for the Mix AC+.
Yes, a dedicated 5000-watt input accepts the output of an existing PV inverter, in addition to the built-in dual MPPT for new panels. That is what allows pooling up to 13 kW of total solar input.
The off-grid output delivers 3680 watts continuously and up to 7200 watts at peak, with a switchover of around 10 milliseconds, enough to start a fridge, a pump or an oven.
The metal enclosure is IP65 rated and operates from -20 to +55°C, allowing outdoor or semi-outdoor installation, under a carport or in a garden shed.
At the time of writing, the dedicated UK listing on zendure.co.uk shows the SolarFlow 4000 Mix Pro (listed there as the 3680 Mix Pro) as sold out. Availability is worth checking directly before planning a purchase.
