Form factor is an installation decision before it is a product decision
| 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 |

What to settle before the first purchase order
Six questions that decide whether the pack performs in the field. Send us the answers and the quotation comes back configured, not generic.
Mounting position and IP rating
Underfloor bays, deck lockers and engine compartments see dust and spray. IP64 covers that; it is not immersion-rated. Specify the actual position, not the vehicle type.
Peak current, not nominal
Compressor fridges, windlasses, bow thrusters and inverters draw heavy inrush. Size cable, fusing and busbar against the 10-second peak rating.
Cold-climate charging
Charging must not start below 0 °C. Discharge continues to -20 °C. For Nordic, Alpine or Canadian markets, raise self-heating or low-temperature cut-off at quotation stage.
Series and parallel topology
Confirm the intended bank layout early. Identical models, matched state of charge and identical cable lengths are prerequisites — mixing capacities or ages in one string is not supported.
Alternator and shore charging
A lithium bank changes alternator loading and shore-charger profile. Confirm the charging sources so the BMS window and charger settings match.
Terminal and connector format
M6 versus M8, stud orientation and cable lug size are the details that stall an installation. Lock them before sample approval.
Sizing from consumption and tariff, not from roof size
| 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 |
What a residential installation typically needs
- 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
What can be configured for a residential storage line
- 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
Technical and purchasing questions
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.
