HiBattery 4020 Now Works Alongside HiBattery 1920 AC and MS-A2: Expand Your Home Energy Storage

Already using a HiBattery 1920 AC or MS-A2 and looking to store more solar energy? Good news! With the latest firmware version (V2.13.0), you can now expand your home energy storage system by adding the HiBattery 4020 Series, allowing compatible devices to work together across different phases of a three-phase electrical system.

Whether you want to increase your energy storage capacity, make better use of your solar power, or improve your household energy management, combining these solutions gives you more flexibility as your energy needs grow.

 

1. Expand Your Existing Energy Storage System

If you already have a HiBattery 1920 AC or MS-A2 installed, you don't necessarily need to replace your existing equipment to increase your storage capacity.

You can add a HiBattery 4020 Series (4.02kWh ~ 16.08kWh) unit to expand your overall energy storage capacity. The devices can operate alongside each other when installed on different phases of a three-phase electrical system.

This provides a flexible way to upgrade your existing solar energy storage setup while making use of the equipment you already own.

 

2. HiBattery 4020 AC or HiBattery 4020 X: Which One Should You Choose?

When expanding your existing home energy storage system, choosing between the HiBattery 4020 AC and HiBattery 4020 X depends on whether you plan to add new solar panels.

 

Choose HiBattery 4020 AC if you want to keep your existing solar system.

If you already have a solar PV system installed and simply want to increase your energy storage capacity, the HiBattery 4020 AC is the ideal choice. It connects to your existing solar system through AC coupling, allowing you to store more of the solar energy your panels generate without purchasing additional solar panels or replacing your existing PV inverter.

Choose HiBattery 4020 X if you plan to add new solar panels.

If you want to expand your solar generation capacity with additional PV panels and prefer not to purchase a separate microinverter, the HiBattery 4020 X is a great option. Its built-in MPPT technology allows you to connect new solar panels directly to the battery through its MPPT inputs, without requiring an additional microinverter.

In short:

• 4020 AC: Ideal for expanding energy storage using your existing solar PV system.
• 4020 X: Ideal for adding new solar panels and connecting them directly to the battery via MPPT.

 

3. Manage Your Energy Storage Through One App

With the S-Miles app, you can manage your compatible HiBattery devices through one unified platform. Once properly installed and configured, your HiBattery 4020 Series and existing HiBattery 1920 AC or MS-A2 can be monitored and managed through the same app.

This makes it easier to keep track of your energy storage system, monitor its operation, and manage your household energy usage.

 

4. Add a Three-Phase Smart Meter for Smarter Energy Management

For households with a three-phase electrical system, installing a compatible Hoymiles Three-Phase Smart Meter is recommended.

The smart meter provides real-time household electricity consumption data, enabling:

• Zero-Feed-In Management: Help prevent excess electricity from being exported to the grid through coordinated system control.
• Better Energy Management: Monitor household electricity consumption and optimize how your stored energy is used.
• Unified Energy Monitoring: Gain better visibility into your household's overall energy flow.

With a compatible smart meter and the appropriate system configuration, you can make better use of your stored solar energy and reduce unnecessary grid feed-in.

 

5. Important Compatibility Notice: Three-Phase Electrical Systems Only

Before expanding your system, please check your household electrical configuration.

The combined use of HiBattery 4020 Series with HiBattery 1920 AC or MS-A2 requires a three-phase electrical system.

The devices must be installed on different phases to work together as one coordinated energy storage setup.

If your household has only a single-phase electrical circuit, this combined configuration is not supported. Installing the devices on the same single-phase circuit will not enable them to operate together as a unified system.

If you are unsure whether your home has a single-phase or three-phase electrical supply, we recommend consulting a qualified electrician before installation.

 

6. Build a More Flexible Home Energy System with Hoymiles

Your energy needs may change over time, and your home energy storage system should be able to grow with them.

By combining the HiBattery 4020 Series with your existing HiBattery 1920 AC or MS-A2 on a compatible three-phase electrical system, you can increase storage capacity while managing your devices through the S-Miles app.

Add a compatible three-phase smart meter to further improve energy monitoring and zero-feed-in management.
