Wall-Mounted LiFePO4 Batteries
Wall-mounted LiFePO4 packs trade floor space for capacity — CMX Battery builds them as slim 48V units for the garage or utility room, ready to hang and wire to a hybrid inverter.
Overview
Wall-mounted home batteries are the default where floor space is scarce: a slim 48V (51.2V) LiFePO4 pack that hangs on a garage or utility-room wall and wires straight to a hybrid inverter. CMX Battery builds them 5–15 kWh with an integrated BMS, IP65 enclosure and the communication your system expects. They suit single-phase homes doing self-consumption and backup, and they keep the floor clear for the inverter and switchgear.
Key specifications
| Specification | Value | Why it matters |
|---|---|---|
| Voltage | 48V (51.2V) | Hybrid-inverter ready. |
| Capacity | 5–15 kWh per unit | Stack or parallel to scale. |
| Form | Slim wall mount, IP65 | Garage/utility room. |
| BMS | Integrated, CAN/RS485 | System monitoring. |
| Weight | Slim, wall-anchored | Check wall rating. |
Typical applications
- Urban and suburban homes: Where floor space is limited.
- Self-consumption + backup: Single-phase residential.
- Garage installs: Wall anchor keeps floor clear.
- Retrofit storage: Adds to existing PV.
How to specify & buying guide
- Confirm the wall can carry the unit's weight when anchored to studs or masonry.
- Match voltage (51.2V) and BMS comms to your hybrid inverter.
- Size 5–15 kWh from daily use and backup need; parallel identical units to grow.
- Keep the unit within the inverter's cable run for low-loss wiring.
Engineering & manufacturing at CMX Battery
Residential systems are built around a 48V (51.2V) LiFePO4 core with a hybrid inverter interface, backup transfer and safe indoor/outdoor enclosure. We size for daily cycling and backup autonomy, and document the system for IEC62619 and UL9540A so your installers can pass inspection.
Certifications & compliance
- UN38.3 — Mandatory lithium battery transport test (altitude, thermal, vibration, shock, external short). Required for any cross-border shipment.
- IEC62619 — International safety standard for industrial Li-ion cells and batteries; expected by EU and most APAC buyers.
- UL1973 — North American safety standard for stationary lithium battery systems.
- CE — EU declaration of conformity for the applicable directives.
- RoHS — Restriction of hazardous substances in the battery and BMS.
- IP65 — Dust-tight and low-pressure water-jet resistant — suitable for outdoor enclosures.
Frequently asked questions
Can I mount it outside?
IP65 enclosures are indoor/outdoor rated; confirm local code for exterior wall mounting.
How many can I stack?
Parallel identical units; total kWh is the sum, within the inverter's current limit.
Does it need a separate BMS?
No, the BMS is integrated; CAN/RS485 feeds your inverter or monitor.
What inverter does it pair with?
Any 48V hybrid inverter whose battery range covers 51.2V LFP.
