Scalable 10kWh All In One Energy Storage System For Home Backup

6kW 10kWh Scalable All In One Energy Storage System for Home Backup

Scalable Residential Storage in One Cabinet

This 6kW 10kWh all in one energy storage system integrates a pure sine wave inverter, battery storage, MPPT solar charger, LCD interface and WiFi monitoring within one cabinet.

The battery provides 10kWh of rated energy and approximately 9kWh of usable energy at 90% depth of discharge. It is suitable for residential solar self-consumption, selected backup circuits and projects requiring a practical starting capacity.

Parallel operation support also gives installers a basis for phased system development. Additional compatible units may be considered when future load demand or required storage capacity increases.

Why Start with a 10kWh Configuration

All In One Energy Management

Solar Power for Current Loads

Available photovoltaic generation can supply compatible household loads during daylight hours according to the selected operating configuration.

Battery Charging and Storage

Solar energy can charge the battery for later use when household demand continues after photovoltaic production decreases.

Utility Charging Support

A compatible utility supply can support loads and battery charging when solar generation is insufficient or unavailable.

Backup Circuit Operation

During a grid interruption, the system can supply selected household circuits. The specified transfer time is 10ms, but equipment with strict continuity requirements should be checked before installation.

Home Backup Load Planning

The 6kW output rating determines how much continuous power can be supplied at one time, while the 10kWh battery capacity determines expected operating duration.

Suitable backup loads may include compatible lighting, routers, televisions, computers, refrigerators, security equipment and selected household outlets.

Pumps, refrigerators, air conditioners and other motor-driven appliances may require substantially higher startup power. Both operating demand and surge demand should be confirmed before circuit selection.

Electrical and Installation Specifications

PV Array Planning

The integrated MPPT charger supports photovoltaic input up to 9000W and 27A. The operating voltage range is 80–450Vdc, while the maximum photovoltaic open-circuit voltage is 500Vdc.

• Calculate the complete photovoltaic string open-circuit voltage before installation.
• Allow for panel voltage increases during low-temperature conditions.
• Keep photovoltaic operating voltage within the 80–450Vdc MPPT range.
• Keep total photovoltaic input current within the specified 27A limit.
• Maximum photovoltaic, AC and combined charging current is 120A.
• Confirm cable size, polarity, connectors and protection devices.

Installation and Expansion Checklist

• Install the IP20 cabinet in a dry indoor or protected technical area.
• Provide suitable floor support for the 118kg net system weight.
• Maintain sufficient ventilation, wiring and maintenance clearance.
• Confirm household voltage and frequency before ordering.
• Separate essential backup circuits from incompatible high-power loads.
• Confirm communication, protection and cable requirements before parallel installation.
• Apply output derating when the installation altitude exceeds 1000m.

All In One Energy Storage FAQ

What does scalable energy storage mean?

It means the system supports parallel configuration, allowing compatible units to be considered for future expansion when storage or output requirements increase.

How much usable energy does the battery provide?

The battery provides approximately 9kWh of usable energy when operated at 90% depth of discharge.

Does adding capacity increase the power of one unit?

The individual unit is rated at 6kW. Output and storage expansion depend on the approved parallel configuration, quantity and project design.

Can the system support refrigerators or pumps?

Selected motor-driven appliances may be compatible when their normal operating power and startup demand remain within the inverter and overload limits.

Can the cabinet be installed outdoors?

The enclosure is rated IP20 and should be installed in a dry indoor or protected technical area. It is not presented as a weatherproof outdoor product.

What information is required before quotation?

Provide the installation country, AC voltage, backup-load list, required runtime, solar panel specifications, initial system quantity and future expansion plan.
