All-in-One Home Energy Storage Systems
An all-in-one system puts the LiFePO4 battery and hybrid inverter in one cabinet — CMX Battery builds them so the install is wiring and commissioning, not integrating separate boxes.
Overview
All-in-one home storage integrates the 48V LiFePO4 battery, hybrid inverter, charge controller and backup transfer into a single cabinet. The appeal is simplicity: one enclosure, one commissioning, one warranty boundary, and no inverter-to-battery compatibility guesswork. CMX Battery builds all-in-one units at 5–20 kWh for grid-tied-with-backup homes and off-grid cabins. The trade-off is flexibility — you cannot mix brands — but for most homes the lower install cost and single point of support win.
Key specifications
| Specification | Value | Why it matters |
|---|---|---|
| Integration | Battery + hybrid inverter + transfer | One cabinet, one commissioning. |
| Energy | 5–20 kWh | Scales per model. |
| Backup | Built-in transfer | Critical or whole-home. |
| Voltage | 48V (51.2V) internal | Matched by design. |
| Warranty | Single boundary | One vendor to call. |
Typical applications
- Grid-tied-with-backup homes: Simplest path.
- Off-grid cabins: Self-contained system.
- Retrofit PV: Adds storage cleanly.
- Quick deployments: Pre-integrated.
How to specify & buying guide
- Confirm the unit's inverter rating (kW continuous/surge) covers your loads, especially motor starts.
- Check the battery capacity matches daily use and backup hours — it is fixed per model, less flexible than separate boxes.
- Verify grid-code and certification for your market before purchase.
- Plan the backup panel (critical loads) with your installer.
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.
- UL1741
- UL9540A — Fire safety test method for ESS installations; often required by US authorities having jurisdiction.
- 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
What is included?
Battery, hybrid inverter, charge controller and backup transfer in one cabinet.
Can I expand the battery?
Depends on the model; some accept parallel batteries, others are fixed.
Is it off-grid capable?
Yes, with an off-grid configuration and enough PV.
Why choose all-in-one over separate?
Lower install cost and a single warranty boundary; less brand-mixing flexibility.
