| Specification | Value |
|---|---|
| Storage | |
| CapacityHow much energy the battery stores. Bigger means longer runtime or more of your own solar power used later. | 1,636 Wh nominal. Indevolt says the system is currently available with a capacity of 3 × 1.636 kWh, with future upgrades possible. |
| Battery chemistryLFP (lithium iron phosphate) cells are known for long life and stable behaviour with heat. | Lithium iron phosphate (LiFePO₄) |
| 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. | 6,000 cycles. Indevolt also lists a lifetime of 15 years. |
| Power | |
| AC output, grid-connectedThe lower output allowed when it feeds power into the home's circuits or the grid. | 800 W |
| Backup outputA separate socket that keeps selected devices running when the grid is down. | 1,200 W off-grid, maximum 1,800 W for 15 seconds |
| Solar | |
| Solar inputHow much solar panel power it accepts. A higher figure fills the battery faster on a sunny day. | 1,200 W, two MPPT inputs of 600 W each |
| Operating voltageThe range of solar panel voltage the unit can use. Panels outside this range will not charge it properly. | 10 to 60 V DC |
| Connection and housing | |
| Dimensions (W × D × H)Check the space before you buy, including room around it for airflow and cables. | 300 × 215 × 250 mm, as listed by Indevolt (axis order not stated) |
| WeightMatters for lifting, wall mounting and moving it. | 16 kg |
| Protection ratingIP ratings show protection from dust and water. IP55 and IP65 are rated for outdoor-style exposure; check the installation guidance. | IP54 |
| Operating temperatureThe range it is rated to work in. Cold and heat can reduce performance. | -20 to 45 °C |
| ConnectivityHow you monitor and control it, usually through an app. | Bluetooth, 2.4 GHz Wi-Fi and 4G |
| CertificationsSafety and grid standards the maker says the product meets. | VDE-AR-N 4105, IEC 62619, UN38.3, IEC/EN 62109-1, IEC/EN 62109-2, IEC/EN 61000-6-1 and IEC/EN 61000-6-2 |

Where this information comes from
We have not tested the BK1600. Every figure above comes from the specification list on Indevolt's Europe product page, last checked on 11 November 2026. The page gives no efficiency, noise level or backup switchover time, so those are shown as not stated.
We do not show prices, because they change often and differ between sellers.
