- 16 kWh
- Made by Deye.
- Energy: 16 kWh nominal per unit (51.2 V, 314 Ah), up to 32 units in parallel, or 64 with a CAN-Bridge.

| 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 unit; rated capacity 314 Ah |
| Usable capacityThe part of the stored energy you can actually use. It is lower than the nominal capacity. | Not stated as a separate figure: Deye gives 100% depth of discharge, adjustable as required |
| Depth of dischargeHow much of the battery can be emptied without harming it. 90% means 10% is kept in reserve. | 100% (adjustable as required) |
| 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 (0.2C charge and discharge, 25 ± 2 °C) |
| ExpansionExtra battery units that add storage to the same system. | Up to 32 units in parallel; up to 64 with a CAN-Bridge. Units can be mounted on the wall, on the floor or stacked up to four layers high. |
| 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 output power 11.8 kW. Charge current 157 A recommended, 160 A maximum continuous, 280 A peak for 10 seconds. Discharge current 157 A recommended, 230 A maximum continuous, 280 A peak for 10 seconds. Current depends on temperature and state of charge. |
| Round-trip efficiencyThe share of the energy you put in that comes back out. The rest is lost as heat. | 95% (DC, at 0.2C and 25 ± 2 °C) |
| 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 |
| Operating voltageThe range of solar panel voltage the unit can use. Panels outside this range will not charge it properly. | 44.8 to 57.6 V |
| Backup in a power cutWhether it can keep selected circuits running during a grid outage. | Depends on the inverter: the battery itself is not an inverter |
| 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 the battery only. The manual says it must be used with a compatible hybrid inverter and must communicate with it. |
| 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: through the hybrid inverter it connects to; the battery 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. | Partly: backup and off-grid operation depend on the connected inverter; Deye does not describe a stand-alone off-grid system for this battery. |
| 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. Built-in circuit breaker for isolation. |
| Dimensions (W × H × D)Width, height and depth of the unit, so you can check that it fits. | 464 × 914 × 244.5 mm (without hanging board and terminals) |
| WeightMatters for lifting, wall mounting and moving it. | 118 kg (approximate) |
| 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. | SE-F16 Max: charging 0 to 55 °C, discharging -20 to 55 °C. SE-F16 Max-H: charging -20 to 55 °C with heating on, discharging -20 to 55 °C. 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. | 0 to 35 °C; relative humidity 95% (non-condensing) |
| Battery heatingA built-in heater that lets the battery charge in cold weather. | Max-H version only: heating allows charging down to -20 °C |
| 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 or floor-mounted; stacking up to four layers |
| DisplayWhether the unit has its own screen showing charge level and power in and out. | LCD showing state of charge and alarms |
| ConnectivityHow you monitor and control it, usually through an app. | CAN 2.0, RS485 and Bluetooth; local Bluetooth app and Deye Cloud monitoring through a Deye inverter |
| CertificationsSafety and grid standards the maker says the product meets. | UN38.3, CE, CB and UL9540A on the brochure; the product page also lists UL1973, UL9540-DC and FCC |
| Warranty | |
| WarrantyThe period the maker covers. Read the terms: conditions and capacity guarantees differ. | 10 years, with conditions: Deye refers to its Warranty Letter |
| 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 covered by the warranty (conditions apply, see Deye's Warranty Letter) |
Compatible with
What Deye says this product works with. Anything not listed here is not confirmed.
- Inverters
- Compatible hybrid inverters only. Deye's brochure, manual and page do not list the models, so ask your installer which Deye inverter to pair with it.
- Parallel use
- Up to 32 units on one bus, or 64 with a CAN-Bridge; units connect with the supplied cables.
- Mounting
- Wall, floor or stacked up to four layers; an optional stacking kit is needed for stacking.
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. Rules, incentives and tax treatment differ by country: see our country guides for what applies where you live.
Strengths and things to check
Strengths
- 16 kWh in one unit, so fewer boxes for a large store
- 100% adjustable depth of discharge and 8,000+ cycles
- Up to 32 units in parallel
- Wall, floor or stacked mounting
- Max-H version can charge in cold conditions
Worth checking before you buy
- A battery only: you need a compatible Deye hybrid inverter as well
- Very heavy at 118 kg, so wall mounting needs a strong wall and helpers
- Deye does not list compatible inverter models in its sources
- The 10-year warranty has conditions in a separate Warranty Letter

Where this information comes from
We have not tested the SE-F16 Max. Every figure above comes from Deye's product page, its SE-F16 Max-H brochure (October 2026) and its SE-F12/F16 user manual (issue 08), last checked on 13 November 2026. The SE-F16 Max and Max-H share one specification table; they differ in the temperature range for charging.
We do not show prices, because they depend on the installer's quote.

Common questions about Deye SE-F16 Max
How much can the SE-F16 Max store?
Each unit holds 16 kWh nominal at 51.2 V and 314 Ah. Deye lists 100% depth of discharge (adjustable), and up to 32 units in parallel, or 64 with a CAN-Bridge.
Does the SE-F16 Max include an inverter?
No. It is a battery only and must be used with a compatible hybrid inverter that communicates with it. Deye's sources do not list the models, so ask your installer.
What is the difference between the Max and Max-H?
The Max-H adds heating. Deye lists charging from 0 to 55 °C for the Max and from -20 to 55 °C with heating on for the Max-H; discharging is -20 to 55 °C on both.
