6kW 16kWh All In One Energy Storage System for Residential Backup Power

Integrated Inverter and Battery System

This 6kW 16kWh all in one energy storage system combines a pure sine wave inverter, battery pack, MPPT solar charger, LCD interface and WiFi monitoring within one cabinet.

The system provides 16kWh of rated battery energy and approximately 14.4kWh of usable energy at 90% depth of discharge. It is suitable for residential backup, solar self-consumption and projects with an unstable utility supply.

Compared with a separately installed inverter and battery, the integrated configuration reduces the number of cabinets, external connections and communication interfaces that installers need to arrange.

Why Use an All In One Energy Storage System

Project Configuration Process

1. Confirm the Backup Load

Calculate the combined continuous demand of lighting, routers, refrigerators, computers, security equipment and other loads that need backup power.

2. Check Starting Power

Refrigerators, pumps, air conditioners and other motor-driven appliances may require significantly more power during startup than during normal operation.

3. Define the Required Backup Time

The system provides approximately 14.4kWh of usable battery energy. Actual operating time depends on load power, conversion efficiency, battery condition and temperature.

4. Match the Solar Array

The photovoltaic string must meet the inverter voltage, current and open-circuit voltage limits under local temperature and sunlight conditions.

Electrical and Installation Specifications

Installation Checklist

• Install the cabinet in a dry indoor or protected technical area because the enclosure is rated IP20.
• Provide suitable floor support for the 136kg net system weight.
• Allow sufficient clearance for ventilation, cable routing and maintenance.
• Confirm the required household voltage and frequency before ordering.
• Keep the photovoltaic string within the 80–450Vdc MPPT range.
• Keep total photovoltaic open-circuit voltage below 500Vdc.
• Apply output derating when the installation altitude exceeds 1000m.

All In One Energy Storage System FAQ

What is integrated inside the cabinet?

The system combines the inverter, battery pack, MPPT solar charging, operating interface and monitoring functions within one cabinet.

How much usable energy is available?

The 16kWh battery provides approximately 14.4kWh of usable energy when operated at 90% depth of discharge.

Can the system supply an entire house?

Whole-home suitability depends on total continuous demand, appliance starting power and required backup time. The combined continuous load must remain within the 6kW rating.

What solar array can be connected?

The system accepts up to 9000W and 27A of photovoltaic input. The MPPT voltage range is 80–450Vdc, and open-circuit voltage must remain below 500Vdc.

How is the system monitored?

The product includes an LCD interface and supports USB communication and WiFi monitoring for operating information and system status.

What should a buyer provide before quotation?

Provide the installation country, AC voltage, backup-load list, required operating time, solar panel specifications, installation environment and order quantity.
