The IVGM and IVAM ranges form part of Felicity Solar’s manufacturer portfolio. Current availability through 3Buy Solar should be confirmed separately from the batteries listed on this page.

Felicity Solar Battery Compatibility – Deye, Growatt, Solis, SolaX & More

One of the key procurement advantages of Felicity Solar batteries is their documented communication compatibility with selected third-party hybrid inverter platforms.

The Felicity Solar inverter compatibility document dated 28 July 2026 identifies:

• 25 inverter brands in the low-voltage compatibility list
• 9 inverter brands in the high-voltage compatibility list
• CAN and/or RS485 communication requirements for specified inverter families
• Different compatibility conditions for individual Felicity battery series

Manufacturers represented in the documentation include Deye, Growatt, Solis, GoodWe, SolaX, Victron, Sungrow and Solplanet, among others.

However, inverter brand compatibility does not mean universal model compatibility. The manufacturer documentation identifies specific inverter families, battery series and communication arrangements.

Before specifying a Felicity Solar battery, installers should verify the exact inverter model, battery voltage range, firmware, BMS protocol, communication wiring and approved battery configuration.

For a detailed technical analysis, read our:

Felicity Solar Battery Compatibility Guide 2026–2027: Supported Inverter Models, CAN/RS485 Communication & Installation Requirements

This guide is particularly useful for installers planning mixed-manufacturer solar battery systems or replacing an existing battery with a Felicity Solar energy storage solution.

Felicity Solar Energy Storage for Residential, Off-Grid & Commercial Projects

Residential Solar Battery Storage

Felicity Solar low-voltage battery systems are suited to appropriately designed residential installations where customers want to store surplus solar electricity and increase their own solar energy consumption.

Typical applications include new rooftop PV installations, battery upgrades and hybrid systems combining photovoltaic generation with energy storage.

Off-Grid Solar & Backup Power

Felicity batteries can also support compatible off-grid solar inverter systems.

For professional off-grid installations, correct battery sizing must account for overnight consumption, seasonal solar generation, inverter output, charging capacity and the required autonomy period.

Backup operation depends on the inverter and overall system architecture; a compatible battery alone does not guarantee uninterrupted power during a grid outage.

Commercial & Industrial Energy Storage

Felicity Solar’s high-voltage battery systems provide storage options for commercial buildings, agricultural facilities, workshops and other business applications.

Depending on the inverter and energy management configuration, commercial battery energy storage systems can support:

• Solar self-consumption and load shifting
• Electricity tariff and time-of-use optimisation
• Peak demand management
• Backup power for designated loads
• Integration with commercial rooftop PV systems

For larger installations, Felicity Solar also develops commercial hybrid inverter systems and cabinet-based battery storage solutions.

Professional buyers can compare related commercial and industrial energy storage systems through 3Buy Solar.
