Who this page is for
Who specifies these systems
Residential storage is bought by people who have to commission it, warrant it and answer the phone afterwards. This page is written for them.

Format selection
Form factor is an installation decision before it is a product decision
Capacity is easy to change at quotation stage. Physical format is not — it determines wall loading, floor loading, lift access, service clearance and whether the unit can legally sit where the customer wants it. Decide format first, then size.
| Format | Typical unit size | Best where |
|---|---|---|
| Wall-mounted | 5.12 – 10.24 kWh | Garage or utility wall, limited floor area |
| Stackable | 2.5 – 5 kWh per module | Capacity grows over time, tight footprint |
| Floor-standing cabinet | 16 – 35 kWh | Plant room, villa, light commercial |
| Rack-mounted | 5 – 15 kWh per shelf | Existing 19-inch rack, telecom-style install |
| All-in-one | 10 kWh + 5 kW inverter | Single-box retrofit, no separate inverter |
Recommended platforms
Platforms specified for residential storage
All share the 51.2 V bus, CAN and RS485 communication, and cycle life quoted with the temperature and depth of discharge it was measured at.
Platform / 01
LD floor-standing cabinets
Three single-enclosure capacities for villa, plant-room and light-commercial installs where one cabinet beats several wall units.

Platform / 02
Wall, stack and rack systems
The volume formats for retrofit and new-build residential, sized from 5.12 kWh to 20.48 kWh per unit.
- 5.12 – 20.48 kWh per unit

Platform / 03
All-in-one battery and inverter
10 kWh storage with a 5 kW pure sine-wave inverter in one enclosure, for retrofits where a separate inverter is not wanted.

- 5,000 W output
- 1 – 9 in parallel, 10 / 20 ms transfer
Engineering decision points
What decides whether commissioning goes smoothly
Most residential storage problems are not battery failures. They are protocol mismatches, access problems and rating mismatches that were settled too late.
01
Inverter model and firmware, not brand
Brand-level compatibility is not enough. Protocol and firmware vary by model within the same brand. Send the exact model and firmware version and we confirm the CAN setting before shipment.
02
Indoor rating versus installation position
Floor-standing cabinets are rated IP20 — indoor only, dry and ventilated. An outdoor or carport install on an indoor rating voids the warranty and creates a real safety risk.
03
Parallel count and current sharing
Up to 15 units are supported. Beyond two or three, confirm busbar and cable sizing, protection coordination and address settings for the specific project rather than assuming symmetry.
04
Cycle life against the tariff
At one cycle per day a 6,000-cycle rating outruns the calendar life of the hardware. At two cycles per day it becomes the binding constraint. Match the specification to the tariff, not to the headline.
05
Access, floor loading and handling
A 35 kWh cabinet is over 250 kg gross. Confirm door widths, lift access, stair turns and floor loading before delivery is scheduled, not on the day.
06
Certification scope for the market
EU, UK, Australia and North America each have different mandatory schemes. Confirm which certificates name the exact model before listing or importing.
Selection guide
Sizing from consumption and tariff, not from roof size
Start with evening and overnight consumption — the energy the battery actually has to cover — then check whether the tariff supports one or two cycles per day.
| Household profile | Evening + overnight use | Suggested capacity |
|---|---|---|
| Apartment, no solar, tariff shifting only | 2 – 4 kWh | 5 kWh |
| Small house with rooftop solar | 4 – 7 kWh | 10 kWh |
| Family house, solar plus EV overnight | 8 – 14 kWh | 15 – 20 kWh |
| Large villa, whole-home backup | 15 – 25 kWh | 20 – 35 kWh |
| Off-grid house, multi-day autonomy | 10 – 20 kWh per day | 35 kWh and above, paralleled |
| Light commercial, evening peak cover | 20 – 40 kWh | 35 kWh, two or more units |
Starting points only. Send the load profile, inverter model, tariff structure, cycles per day and ambient temperature range for a sized proposal.
Compliance for this application
What a residential installation typically needs
Residential storage carries both transport documentation and market-access requirements, and the second one is where projects stall. Confirm the mandatory scheme for your market before committing to stock.
- UN38.3 Test Summary and SDS for every shipment
- Dangerous goods packaging documentation for sea freight
- CE Declaration of Conformity for EU placement
- IEC 62619 / IEC 63056 test evidence, commonly requested
- UL 1973 and UL 9540 listing for permitted North American installs
- AS/NZS 5139 context and CEC listing for the Australian channel
OEM / ODM scope
What can be configured for a residential storage line
Define the scope before sample production. Enclosure and app decisions in particular are expensive to revisit after tooling.
- Capacity, module count and expansion path
- Inverter protocol set and default addressing
- Enclosure colour, finish, logo and label
- Touch LCD screen, Bluetooth telemetry, iOS / Android app
- Self-heating kit and active fire suppression module
- Manual, quick-start guide, carton and pallet configuration
Buyer questions
Technical and purchasing questions
For a project-specific answer, send the inverter model and the load profile.
Mainstream hybrid brands including Deye, Solis, GoodWe, Growatt, Sofar and SMA over CAN, RS485 or RS232. Protocol selection is model-specific, so send the exact inverter model and firmware version and we confirm the setting rather than asking you to work through the menu on site.
Up to 15 for the 51.2 V platforms, and 1 to 9 for the all-in-one system. Beyond a small number of units, confirm total current, busbar and cable sizing, protection coordination and address settings for the specific project.
It is specified at 25 °C ambient and 80 % depth of discharge. Those conditions are part of the specification, not a footnote. A cycle figure quoted without a temperature and a depth of discharge cannot be compared with it.
The floor-standing cabinets are rated IP20 and are for indoor installation in a dry, ventilated space. For outdoor projects, tell us the site conditions at quotation and we will advise on an alternative rather than let an indoor-rated unit go outside.
Wall-mounted for garage and utility walls with limited floor area, stackable where capacity grows over time, floor-standing for villa and plant-room installs, rack where a 19-inch rack already exists. Format is an installation constraint; decide it before capacity.
It depends on the destination. EU placement needs a CE Declaration of Conformity; North American permitted installs frequently require UL 1973 and UL 9540 listing; the Australian residential channel effectively requires CEC listing. Tell us the market and we will confirm what we hold and what we do not.
