Specifications
Last checked on 13 November 2026. The grey text under each name explains what the value means. To see it next to other products, compare it in our comparison tool.
| 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 per battery module (314 Ah); 16, 32, 48, 64, 80 or 96 kWh with one to six modules |
| Usable capacityThe part of the stored energy you can actually use. It is lower than the nominal capacity. | 14.4 kWh per module under test conditions (25 ± 2 °C, new battery, 0.2C, 90% depth of discharge) |
| Depth of dischargeHow much of the battery can be emptied without harming it. 90% means 10% is kept in reserve. | 90% recommended |
| 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. | 8,000 cycles or more to 70% of original capacity (25 ± 2 °C) |
| ExpansionExtra battery units that add storage to the same system. | Up to six battery modules per inverter (96 kWh); up to three inverters in parallel (60 kW three-phase, 36 kW single-phase). A modular expansion base reduces wiring. |
| Power | |
| AC output (continuous)The power it can deliver all the time. Add up the watts of what you want to run at once and stay below this. | Single-phase 3.6, 4, 4.6, 5, 6, 7.5, 8, 10 or 12 kW; three-phase 5, 6, 8, 10, 12, 15 or 20 kW |
| Peak outputA short burst above the continuous rating, for example to start a motor. It cannot be held. | Off-grid peak power is two times the rated power for 10 seconds |
| Charge and discharge powerHow fast the battery can take in and give out energy. It sets how many devices it can serve at once. | Battery module: charge 160 A continuous (192 A peak), discharge 220 A continuous (264 A peak). Inverter battery current up to 90 to 250 A single-phase and 120 to 380 A three-phase, depending on the model. |
| Round-trip efficiencyThe share of the energy you put in that comes back out. The rest is lost as heat. | 95% for the battery (DC, 0.2C, 25 ± 2 °C). Inverter: 97.6% maximum, 96.5 to 97.0% European, MPPT above 99%. |
| 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 per battery module |
| Operating voltageThe range of solar panel voltage the unit can use. Panels outside this range will not charge it properly. | 41.6 to 58.4 V |
| Backup in a power cutWhether it can keep selected circuits running during a grid outage. | Supports backup power for connected loads in a grid outage, with seamless on/off-grid switching. Available power and runtime depend on the inverter, battery configuration and household demand. |
| Solar | |
| Solar inputHow much solar panel power it accepts. A higher figure fills the battery faster on a sunny day. | Single-phase: 2 to 3 MPPT trackers, 150 to 425 V MPPT range, 500 V maximum, 7.2 to 24 kW PV access power. Three-phase: 2 to 3 MPPT trackers, 160 or 200 to 650 V MPPT range, 800 V maximum, 10 to 40 kW PV access power. Up to 200% PV oversizing. |
| 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: the built-in hybrid inverter has its own solar inputs and supports AC coupling. |
| 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. | Partly: Deye lists off-grid peak power, backup for connected loads, smart diesel generator control and seamless on/off-grid switching, but does not describe a complete stand-alone off-grid home system. |
| Connection and housing | |
| Grid connectionThe supply type it is built for. Check it matches your home's supply. | Single-phase 220/230 V or three-phase 220/380 V or 230/400 V, 50/60 Hz. Grid codes listed include G99, VDE-AR-N 4105, EN 50549, CEI 0-21, UNE 217002 and AS 4777.2. |
| Dimensions (W × H × D)Width, height and depth of the unit, so you can check that it fits. | Battery module: 662 × 715 × 257 mm (without base). Inverter cabinet: 662 × 331 to 450 × 255 mm, depending on the model. |
| WeightMatters for lifting, wall mounting and moving it. | 120 kg per battery module; inverter 20.5 to 34 kg depending on the model |
| Protection ratingIP ratings show protection from dust and water. IP55 and IP65 are rated for outdoor-style exposure; check the installation guidance. | IP66 for the system; Deye also states short-term immersion resistance in 0.5 m of water (tested, not covered for liquid damage under warranty) |
| Operating temperatureThe range it is rated to work in. Cold and heat can reduce performance. | AI-W16: charging 1 to 55 °C, discharging -20 to 55 °C (derating above 45 °C). AI-W16-H: charging -20 to 55 °C with heating on. Altitude up to 3,000 m. |
| Battery heatingA built-in heater that lets the battery charge in cold weather. | AI-W16-H version only: heating allows charging down to -20 °C |
| Storage conditionsThe temperature, humidity and recharge routine the maker recommends if you store the unit for weeks or months. | Battery: 0 to 35 °C, relative humidity 95% (non-condensing) |
| CoolingHow the heat is removed. Natural cooling is silent; air cooling uses a fan. | Natural cooling for the system; the inverter data tables list intelligent air cooling |
| Noise levelFan noise while working. | Inverter below 45 dB to below 55 dB depending on the model (50 dB or less on one three-phase model) |
| 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. | Floor-mounted, stack-mounted on a modular expansion base |
| DisplayWhether the unit has its own screen showing charge level and power in and out. | LCD and LED on the system; LED status on the battery |
| ConnectivityHow you monitor and control it, usually through an app. | Wi-Fi, RS485, CAN, LoRa and Bluetooth; Deye Cloud app and web monitoring, with LoRa wireless CT for local zero-export control without internet |
| CertificationsSafety and grid standards the maker says the product meets. | Battery: UN38.3, CE, CB, UL9540A. System standards include IEC 62619, IEC 62477 and IEC 62109-1/-2. |
| Warranty | |
| WarrantyThe period the maker covers. Read the terms: conditions and capacity guarantees differ. | Battery module 10 years (conditions apply, see Deye's Warranty Letter). The product page and the system table state a standard 5 years for the system, with an extendable warranty. |
| Energy throughputHow much total energy the warranty covers over the battery lifetime. Warranties often end at the stated years or this throughput, whichever comes first. | 50 MWh per battery module (conditions apply, see Deye's Warranty Letter) |
