6kW 16kWh All In One Home Energy Storage System With Dual MPPT

6kW 16kWh All In One Energy Storage System with Dual MPPT for Home Backup

Integrated Solar Storage for Residential Projects

This 6kW 16kWh all in one energy storage system integrates a hybrid inverter, battery storage, dual MPPT solar charging, system communication and WiFi monitoring within one cabinet.

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

Its integrated structure reduces the number of separate inverter, battery and monitoring components that installers need to position and connect during residential energy storage deployment.

Dual MPPT Solar Input Design

The dual MPPT design allows installers to manage two photovoltaic input groups within the specified electrical limits. This can be useful when solar modules are installed on roof sections with different orientations or operating conditions.

All In One Energy Management

Solar Power for Household Loads

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

Battery Charging and Energy Storage

Surplus solar generation can charge the battery for later use when current photovoltaic output is lower than household demand.

Utility Power Coordination

A compatible utility connection can support household loads and battery charging when solar generation is insufficient.

Backup Circuit Supply

During a grid interruption, the backup output can supply selected household circuits. The specified automatic transfer time is less than 20ms, but compatibility should still be confirmed for equipment with strict continuity requirements.

Residential Backup Load Planning

The system can support compatible lighting, routers, computers, televisions, refrigerators, security equipment and other selected home loads within the 6kW output limit.

The 16kWh battery determines expected backup duration, while the 6kW inverter determines the combined continuous power that can be supplied at one time.

Refrigerators, pumps, air conditioners and other motor-driven appliances may require higher startup power. Their normal and starting demand should be checked before being included in the backup circuit.

Electrical and Installation Specifications

Installation and PV String Checklist

• Calculate the complete photovoltaic string open-circuit voltage before installation.
• Keep the MPPT operating voltage within the specified 80–520Vdc range.
• Keep photovoltaic open-circuit voltage below 550Vdc under low-temperature conditions.
• Do not exceed the specified current limit for either MPPT input.
• Provide a stable floor or mounting position suitable for the 167kg cabinet weight.
• Maintain suitable ventilation, cable routing and maintenance clearance.
• Apply output derating when the installation altitude exceeds 1000m.

All In One Energy Storage FAQ

What is included in the integrated cabinet?

The cabinet combines the hybrid inverter, battery storage, dual MPPT solar charging, system communication and monitoring functions.

Why does this system use dual MPPT inputs?

Dual MPPT inputs provide additional flexibility when designing photovoltaic arrays with different roof orientations or operating conditions, provided each input remains within its voltage and current limits.

How much usable energy is available?

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

Can it supply an entire home?

Whole-home suitability depends on continuous load, appliance startup power and required backup time. Selected essential circuits are generally easier to configure within the 6kW output limit.

Can the system be installed outside?

The cabinet is rated IP65, but installation suitability depends on exposure, cable sealing, temperature, drainage and local electrical requirements. A protected installation position is recommended.

What information is needed for a project quotation?

Provide the installation country, household voltage, backup-load list, required operating time, solar panel specifications, roof orientation, installation location and order quantity.
