10.5 kWh Energy Capacity

With a 10.5 kWh total capacity, this battery provides substantial energy storage for homes and other suitable stationary applications.

The specified Enphase IQ Battery 10 configuration has approximately 10.08 kWh of usable energy, allowing stored solar energy to be used later rather than immediately exported or consumed.

Actual available energy can vary depending on operating conditions, system configuration, battery management settings, temperature, and other installation factors.

Lithium Iron Phosphate Chemistry

The battery uses Lithium Iron Phosphate (LFP) chemistry, also known as LiFePO4.

LFP is widely used in stationary energy-storage applications because of its combination of energy-storage capability, thermal characteristics, durability, and suitability for repeated charge/discharge operation.

For customers looking for a modern battery chemistry for solar storage and backup applications, LFP provides a strong alternative to conventional lithium-ion chemistries.

High Battery Efficiency

The specified Enphase IQ Battery 10 documentation lists 96% battery round-trip efficiency. This represents the battery portion of the system and should be distinguished from complete system AC round-trip efficiency, which can be lower after accounting for power-conversion components and other system losses.

This high battery efficiency helps maximize the amount of energy retained during charging and subsequently available during discharge.

Solar Energy Storage

The Enphase battery can be used as part of a compatible solar-plus-storage installation.

During periods of solar generation, excess energy can be stored in the battery. Stored energy can subsequently be used during periods when solar production is lower, such as:

• Evening and nighttime
• Cloudy periods
• High-demand periods
• Utility outage conditions when the complete system is configured for backup

This can help increase utilization of locally generated solar energy and reduce dependence on grid electricity, subject to the system design and local utility requirements.

Backup Power Applications

When installed with the appropriate compatible Enphase equipment and configured for backup operation, the battery can provide stored energy to selected loads or a supported electrical installation during a grid outage.

Backup capability depends on the complete energy system, including compatible inverters/microinverters, control equipment, electrical configuration, and local installation requirements. The battery should therefore be considered as part of an integrated energy-storage system rather than as a standalone AC backup generator.

Integrated Energy Storage Architecture

The Enphase IQ Battery 10 configuration incorporates battery storage with integrated Enphase power-conversion and battery-management components. Enphase documentation describes the system as an integrated battery system consisting of three battery base units together with the associated cover, mounting hardware, and interconnection components.

This integrated architecture can simplify system design compared with installations requiring multiple separate battery and inverter components.

Natural Convection Cooling

The specified system uses natural convection cooling and does not require cooling fans. This design eliminates fan-based active cooling within the battery assembly and helps simplify the mechanical design.

The specified operating temperature range is -15°C to 55°C, with an optimum operating temperature range of approximately 0°C to 30°C for the referenced configuration.

Installation should always follow the manufacturer’s environmental, clearance, ventilation, and temperature requirements.

Outdoor Installation

The referenced Enphase IQ Battery 10 configuration uses an outdoor NEMA Type 3R enclosure and is designed for wall mounting. The published dimensions are approximately 1,070 × 664 × 319 mm (W × H × D), with a total listed weight of approximately 154.7 kg including the battery base units, cover, and mounting bracket.

Because of its substantial weight and electrical characteristics, professional installation is recommended.

System Integration

The Enphase battery is intended to operate as part of a compatible Enphase energy ecosystem rather than as a generic standalone battery.

Depending on the exact model and regional configuration, Enphase storage systems can integrate with compatible solar microinverters, gateways, monitoring equipment, and other energy-management components.

Compatibility should be confirmed before purchase, particularly when integrating with an existing solar installation or equipment from a different generation or region.

Monitoring and Energy Management

Compatible Enphase storage systems can be integrated with Enphase monitoring and energy-management solutions, allowing system owners and installers to monitor energy production, consumption, storage, and system performance.

Monitoring capabilities depend on the complete system configuration and the applicable Enphase hardware, software, and regional services.

Ideal Applications

Residential Solar Storage

Store surplus solar energy generated during the day and use it later when solar generation decreases.

Solar Self-Consumption

Increase the proportion of locally generated solar energy that can be consumed by the property.

Backup Power

Provide stored energy for compatible backup configurations when combined with the required Enphase equipment.

Energy Load Management

Store energy for use during periods of higher electricity demand or according to a configured energy-management strategy.

New Solar Installations

Suitable for integration into compatible new residential solar-plus-storage systems.

Existing Enphase Systems

Can be considered for compatible Enphase installations requiring additional energy-storage capacity, subject to model and regional compatibility.
