| Specification | Value |
|---|---|
| Storage | |
| CapacityHow much energy the battery stores. Bigger means longer runtime or more of your own solar power used later. | 16 kWh (nominal) |
| Usable capacityThe part of the stored energy you can actually use. It is lower than the nominal capacity. | 14.4 kWh |
| Battery chemistryLFP (lithium iron phosphate) cells are known for long life and stable behaviour with heat. | Lithium iron phosphate (LiFePO4), 51.2 V 314 Ah |
| Depth of dischargeHow much of the battery can be emptied without harming it. 90% means 10% is kept in reserve. | Not stated as a percentage; usable 14.4 kWh of 16 kWh is 90% (our calculation) |
| 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. | 8,000 cycles; energy throughput 100 MWh on the datasheet (the product page says 95,000 kWh over its lifetime) |
| ExpansionExtra battery units that add storage to the same system. | Up to 12 systems in parallel; Duracell says more batteries can be added at any time |
| Power | |
| Charge and discharge powerHow fast the battery can take in and give out energy. It sets how many devices it can serve at once. | Maximum 130 A, battery power 6.6 kW |
| Nominal voltageThe voltage the battery is rated for. It decides which inverter or system voltage (12, 24 or 48 V) it fits. | 51.2 V DC |
| Operating voltageThe range of solar panel voltage the unit can use. Panels outside this range will not charge it properly. | 43.2 to 58.4 V DC (single phase) |
| Round-trip efficiencyThe share of the energy you put in that comes back out. The rest is lost as heat. | Not published by Duracell Energy |
| Backup in a power cutWhether it can keep selected circuits running during a grid outage. | Not stated: not described on the Dura16 page or datasheet, and the battery has no AC output of its own |
| Solar | |
| Solar inverterTurns the DC power from solar panels into AC for the home. Built in means no separate solar inverter is needed. | None: this is a battery only; it is paired with an inverter |
| Solar and off-grid | |
| Works with solar panelsWhether you can charge it from solar panels. Yes means a built-in solar input or a compatible solar setup; read the detail for the voltage and power limits. | Yes: Duracell says it pairs with new and existing solar panels, through an inverter; it has no solar input of its own. |
| Off-grid useWhether the maker describes it running with no grid connection at all, for example in a cabin, van or off-grid home. Backup only means it covers power cuts but needs the grid the rest of the time. | No: Duracell does not describe off-grid or backup use for the Dura16. |
| Connection and housing | |
| Grid connectionThe supply type it is built for. Check it matches your home's supply. | Not applicable: the battery connects to an inverter over DC (communication CAN / RS485) |
| Dimensions (W × H × D)Width, height and depth of the unit, so you can check that it fits. | 520 × 860 × 236 mm (±2 mm) |
| WeightMatters for lifting, wall mounting and moving it. | 122 kg (135 kg packaged) |
| MountingWhere and how it can be fixed: on the floor, on a stand or on a wall. It decides the space and the wall strength you need. | Wall-mounted |
| Protection ratingIP ratings show protection from dust and water. IP55 and IP65 are rated for outdoor-style exposure; check the installation guidance. | IP65; indoor or outdoor; humidity 5 to 85% RH |
| Operating temperatureThe range it is rated to work in. Cold and heat can reduce performance. | -10 to 60 °C charging, -20 to 60 °C discharging; altitude up to 3,000 m |
| Storage conditionsThe temperature, humidity and recharge routine the maker recommends if you store the unit for weeks or months. | -20 to 45 °C for up to 1 month, 0 to 35 °C for up to 1 year; humidity below 60% RH |
| Battery heatingA built-in heater that lets the battery charge in cold weather. | Not stated by Duracell Energy for the Dura16 |
| CoolingHow the heat is removed. Natural cooling is silent; air cooling uses a fan. | Natural convection; fanless, no noise |
| DisplayWhether the unit has its own screen showing charge level and power in and out. | LED indicator |
| ConnectivityHow you monitor and control it, usually through an app. | CAN and RS485 communication ports |
| CertificationsSafety and grid standards the maker says the product meets. | Not published by Duracell Energy on the datasheet |
| Warranty | |
| WarrantyThe period the maker covers. Read the terms: conditions and capacity guarantees differ. | 10 years |
Compatible with
What Duracell Energy says this product works with. Anything not listed here is not confirmed.
- Inverters
- The datasheet does not name compatible inverters; Duracell's own hybrid inverter is the Dura-i.
- Tariffs
- Duracell says it works with all major non-grid-services tariffs and can charge during low-cost periods.
- Installation
- Wall-mounted, indoors or outdoors.
Rules where you live
An installed battery normally needs a qualified electrician, and in many countries you must also tell your grid operator, especially if it can export. This is not a plug-in battery. Rules, incentives and tax treatment differ by country: see our country guides for what applies where you live.
