| Specification | Value |
|---|---|
| Storage | |
| CapacityHow much energy the battery stores. Bigger means longer runtime or more of your own solar power used later. | 2.4 kWh for the base unit. Zendure lists 5.28 kWh with one AB3000L added. |
| Battery chemistryLFP (lithium iron phosphate) cells are known for long life and stable behaviour with heat. | LiFePO4 (LFP) |
| Cycle lifeHow many full charge and discharge cycles the cells are rated for before they hold less than the stated share of their original capacity. | Not stated. Zendure gives a 10-year warranty and a lifespan of up to 15 years. |
| ExpansionExtra battery units that add storage to the same system. | Up to five AB3000L batteries of 2.88 kWh each: 16.8 kWh in total |
| Power | |
| AC output, grid-connectedThe lower output allowed when it feeds power into the home's circuits or the grid. | 2,400 W bi-directional AC; the default setting is 800 W |
| Backup outputA separate socket that keeps selected devices running when the grid is down. | 3,200 W off-grid power, grid-assisted |
| Efficiency and standby useLosses when charging, discharging and doing nothing. | Not stated |
| Solar | |
| Solar inputHow much solar panel power it accepts. A higher figure fills the battery faster on a sunny day. | No direct solar input is listed. It is AC-coupled and works with the inverter of a rooftop solar system. |
| Connection and housing | |
| Dimensions (W × H × D)Width, height and depth of the unit, so you can check that it fits. | Not stated on the product page |

| Protection ratingIP ratings show protection from dust and water. IP55 and IP65 are rated for outdoor-style exposure; check the installation guidance. | IP65 |
| Operating temperatureThe range it is rated to work in. Cold and heat can reduce performance. | Not stated. The batteries have low-temperature self-heating. |
| Noise levelFan noise while working. | Not stated |
| ConnectivityHow you monitor and control it, usually through an app. | Zendure app; MQTT for Home Assistant and Homey. A Smart CT meter connects by RJ45. |

Rules where you live
Rules for plug-in batteries differ by country. Zendure's page describes 'plug and play' set-up (plug into the wall, connect a Smart CT, activate in the app) and prices it in euros. It does not say whether a UK version or UK plug exists. In Great Britain, plug-in solar kits of up to 800 VA have been legal since 27 August 2026, but the rules exclude plug-in batteries.
Check the rules, incentives and tariffs for your own country in our country guides.
Strengths and things to check
Strengths
- 2,400 W bi-directional AC, a high output for a plug-in style battery
- Expandable to 16.8 kWh
- 10-year warranty and IP65
- Works with an existing rooftop solar system
Worth checking before you buy
- Zendure's page gives no dimensions, weight, cycle life or noise figure
- Output defaults to 800 W; whether 2,400 W is allowed depends on your country's rules
- No direct solar input: it needs an existing solar system or a grid connection to charge
- Whether it counts as a plug-in product depends on your country: check the rules below
