Solar home with residential battery storage

RESIDENTIAL ENERGY STORAGE / SOLAR & BACKUP

Store daylight. Keep life running.

Modular LiFePO₄ home storage engineered around actual household loads, solar production, grid rules and the backup reserve a family really needs.

MODEL-SPECIFIC COMPLIANCE EVIDENCE

Safety and transport files available before order confirmation.

LithVolt and Shenzhen Shungong maintain model-specific compliance files for selected energy-storage configurations — including EMC evidence supporting the CE technical file, EN IEC 62619:2022 safety evidence, UN 38.3 transport testing, SDS/MSDS, and sea/road transport documents where applicable. Every file is matched to the ordered model, rating and revision before it is released as project evidence.

Example coverage in hand: SCAE-A-51.2-100 (EMC + EN IEC 62619 + UN 38.3) · SCAP-A-51.2-100 (EMC + EN IEC 62619 + UN 38.3) · SCLFP · SDS/MSDS and sea/road transport by exact model.

Additional file sets can be confirmed for selected SCAE, SCAP and SCLFP models. Documents are issued on request after model lock-in — they are not published as open downloads.

These are model-specific technical records held by LithVolt / Shenzhen Shungong for the quoted configuration. They are not a blanket certification of every catalogue item and do not replace destination-market approval. Confirm nameplate, dimensions, electrical rating, report revision, transport mode and country requirements on each order.

THREE ENERGY GOALS

Backup, savings and independence are not the same design.

01

Essential-load backup

Keep selected lights, refrigeration, communications, pumps and outlets running through an outage.

02

Solar self-consumption

Store midday surplus and use it after sunset instead of exporting or curtailing it.

03

Off-grid & weak-grid

Support longer outages with larger reserve, solar and sometimes a generator—without treating the grid as guaranteed.

REFERENCE SYSTEMS

Capacity covers time. Power starts appliances.

Energy in kWh determines how long loads can run; inverter kW and surge capability determine which loads can start and operate together.

Essential

Apartment / small home

5.12 kWh

Battery51.2 V 100 Ah

Inverter3–5 kW hybrid inverter

Lights, router, TV, refrigerator and selected outlets.

Core home

Typical family home

10.24 kWh

Battery51.2 V 200 Ah

Inverter5–8 kW hybrid inverter

Longer essential backup plus broader evening solar use.

High-use

Large loads / weak grid

15.36 kWh

Battery3 × 5.12 kWh modules

Inverter8–12 kW system

More reserve for pumps, cooling zones and longer interruptions.

Scalable

Battery4+ × 5.12 kWh modules

InverterEngineered per phase/load

Project-designed solar, generator and critical-load strategy.

Nominal energy is not the same as delivered AC energy. Reserve state of charge, allowed depth of discharge, conversion losses, temperature and battery aging must be included.

INTELLIGENT ENERGY PLANNING

See the whole system. Size it with confidence.

Follow power from solar and grid through the inverter, battery and home. Adjust your load to receive a transparent first-pass configuration.

Planning estimate only. Motor surge, cable length, temperature, PV string Voc and local electrical rules require final engineering verification.

ENERGY FLOW

Design the whole electrical system—not a battery in isolation.

A safe home ESS coordinates PV, battery, inverter, grid, generator and protected loads while meeting the destination market’s interconnection rules.

Protected residential energy storage installation

PV & MPPT

Array voltage/current must stay inside the selected inverter or charge-controller window in all temperatures.

Grid & transfer

Anti-islanding, export limits, backup transfer and neutral/earthing behavior are market- and topology-specific.

Critical-load panel

Separate essential circuits so limited stored energy is not consumed by ovens, heaters or other unintended loads.

Residential installation essentials

  • Use a compatible battery, BMS, inverter and approved communication protocol.
  • Install only in permitted locations with required clearance, temperature and ingress protection.
  • Provide DC isolation, correctly rated overcurrent protection and touch-safe terminals.
  • Size cables, busbars, grounding and surge protection for fault and continuous current.
  • Commission charge limits, reserve SOC, transfer behavior and emergency shutdown.
  • Confirm local electrical, fire, utility and permitting rules with a qualified installer.

SIZING WORKFLOW

Start with loads, outage hours and solar—not house size.

Audit energy

Use utility bills and 15/30-minute data where available; separate daily kWh from peak kW.

Choose backup loads

Record continuous power, starting surge and required outage hours for each critical circuit.

Model solar & seasons

Check roof yield, winter production, shading, export policy and desired self-consumption.

Confirm site & market

Phase type, grid code, mounting area, temperature, internet/communications and permitting.

WORKED EXAMPLE

If selected loads average 500 W for 10 hours, they consume 5 kWh AC. After reserve and conversion losses, a nominal 5.12 kWh battery is unlikely to cover the full target; a 10.24 kWh class system provides more realistic margin. A separate check must confirm refrigerator or pump starting surge.
