Indoor 15 KWh Battery Storage System For Home , Long Life Household Energy

Product Overview

A 15 kWh stackable home battery with an integrated 5 kW inverter, 120 V AC output and up to 6 kW PV input. The appliance-style enclosure brings solar charging and battery storage into a tidy indoor system.

This configuration uses 3 battery modules beneath the integrated inverter section. It combines a 51.2 V LFP battery platform with solar-input and AC power functions for a defined household load plan. The listing configuration is 15 kWh; the 5 kW output rating remains the same across this series.

Designed to Fit into the Home

Stacked structure for simpler installation planning

The inverter and battery modules share a coordinated vertical enclosure. A predefined stack helps the installer organize equipment placement and the system interfaces, with the final connections and commissioning completed to the selected configuration.

Appliance-style appearance

A clean front panel, integrated display and floor-standing form create the appearance of a household appliance. The system can fit into a suitable indoor utility space with the required ventilation and service clearances.

Solar-ready integrated system

The built-in PV input accepts a suitably designed solar array, with up to 6 kW PV power and a 70-280 V DC MPPT range. Panels, strings and protective devices must be matched to the 300 V DC maximum and 30 A input limit.

Capacity matched to the household

Choose stored energy according to daily consumption and backup duration, while checking the 5 kW AC rating against simultaneous loads. This listing is for the 15 kWh stack; additional capacity is an energy choice, not an automatic power upgrade.

The comparison image shows the three configurations in this series. This listing is for the 15 kWh configuration shown in the first product image. Additional battery modules increase stored energy; they do not automatically increase the inverter power rating. Future expansion requires confirmation of compatible modules, controls and installation limits.

Residential Application Scenarios

A larger household energy reserve

The three-battery stack increases nominal stored energy while keeping AC output at 5 kW. It is relevant when the main requirement is a longer energy window for selected household loads rather than higher instantaneous power.

Homes with extended evening demand

Store available solar energy for a longer evening-use plan, subject to usable capacity and the selected inverter mode. Compare daily demand, solar generation and recharge availability when deciding whether the largest stack is appropriate.

Remote or intermittently occupied homes

A larger reserve can support a planned operating schedule at a 120 V residence with a compatible solar and backup-source arrangement. Seasonal energy balance and the maximum simultaneous load remain the key design inputs.

Direct Solar Input and Home Power Flow

Solar modules feed the integrated PV input, and the all-in-one unit supplies selected 120 V AC home loads. A compatible AC source can connect to the AC input in the approved configuration. The source illustrates grid or generator input; switching and source compatibility must be engineered for the installation.

The diagram is a functional concept, not an installation wiring plan. Grid and generator are alternative AC-source arrangements requiring suitable switching. The supplied source offers off-grid or hybrid inverter configurations; grid export, parallel operation and local grid approval are not established by this listing.

Technical Specifications

The source states 15 kWh for the 51.2 V / 300 Ah version. Multiplication gives 15.36 kWh; this listing retains the source-stated 15 kWh pending confirmation.

The efficiency is reproduced as ≤91% in the supplied datasheet. The value and inequality require confirmation and are not used as a promotional efficiency claim.

The dimensions are reproduced in the order shown by the source; the source does not label the axes. Appearance and final specifications may vary by configuration.

Installation and Configuration

The 15 kWh configuration is listed at 550 × 170 × 1705 mm and approximately 138 kg. Plan delivery access, lifting and a stable installation surface before positioning the stack. The integrated format can simplify the equipment layout; it does not imply tool-free or plug-in installation.

An appliance-style enclosure simplifies placement and keeps the system visually tidy, but electrical installation is performed by a qualified installer. Confirm floor loading, clearances, earthing, circuit protection, isolation, cable sizing and local requirements. IP20 specifies an indoor installation; the system is not presented as weatherproof outdoor equipment.

Frequently Asked Questions

Can I connect photovoltaic panels directly?

Yes, through the specified PV input when the array is designed within the 6 kW, 300 V DC maximum, 70-280 V DC MPPT and 30 A limits. Confirm string sizing against module open-circuit voltage at the lowest design temperature.

Is this compatible with every household supply?

This series specifies 120 V AC output. Supply voltage, frequency, earthing and the selected off-grid or hybrid inverter version must match the project; it should not be represented as a 230 V or split-phase product.

Will a larger battery increase output power?

No. The 5.12, 10.24 and source-stated 15 kWh configurations retain a 5 kW inverter rating. Battery capacity changes the available energy reserve, while runtime also depends on load, reserve settings and conversion losses.
