An all-in-one system puts the LiFePO4 battery and hybrid inverter in one cabinet — EGbatt 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. EGbatt 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.

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 EGbatt

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.
