10kWh is the sweet-spot residential size — enough for a day of self-consumption and a few hours of backup — and EGbatt builds it as a 48V LiFePO4 pack ready for a hybrid inverter.

Overview

A 10kWh LiFePO4 battery is the most common residential size because it covers a typical home’s evening use after a sunny day and carries critical loads through a short outage. EGbatt delivers it as two 5.12kWh 48V (51.2V) modules in wall or rack form, with an integrated BMS and the communication a hybrid inverter expects. It is the right starting point for most grid-tied-with-backup homes; add modules later if usage grows.

Typical applications

  • Daily self-consumption: Store PV, use at night.
  • Short outage backup: Critical loads.
  • Starter home storage: Expandable later.
  • Time-of-use shifting: Where allowed.

How to specify & buying guide

  • If evening use exceeds what 10 kWh covers, start at 15–20 kWh rather than adding later (cleaner one-time install).
  • Confirm the inverter's 48V range and that it is hybrid (PV+battery+grid).
  • Decide wall vs rack from available space and future expansion plans.
  • Get IEC62619/UL9540A docs if your utility or rebate requires them.

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.
  • UL1973 — North American safety standard for stationary lithium battery systems.
  • 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

Is 10kWh enough for a home?

For evening self-consumption and short backup, usually yes; heavy all-electric homes need more.

Can I expand later?

Yes — parallel identical modules to grow capacity.

What inverter do I need?

A 48V hybrid inverter whose battery range covers 51.2V LFP.

How long does it back up the house?

Hours for critical loads; whole-home depends on the inverter and load.
