What are the EG4 Wallmount Batteries?

The EG4 14.3 kWh Wallmount Indoor Battery and EG4 14.3 kWh Wallmount All Weather Battery deliver high-performance lithium-iron-phosphate (LiFePO4) battery systems tailored for residential use. The Indoor model thrives in sheltered spaces like garages or basements, while the All Weather version conquers outdoor conditions, providing flexibility for any home setup. Both units engineer efficiency, safety, and seamless integration with solar systems, making them ideal for storing energy in high-rate states like California, Texas, or New York.

Core Specs (Both Models)

• Capacity: 14.3 kWh, capable of powering essential loads (lights, fridge, Wi-Fi) for 12-24 hours during outages, depending on usage.
• Voltage and Compatibility: 48V nominal, designed for plug-and-play performance with EG4 inverters and other 48V systems.
• Dimensions and Weight: Compact, wall-mounted design (approximately 35”H x 22”W x 10”D, ~200 lbs), saving floor space in indoor or outdoor setups.
• Scalability: Expandable with up to 4 units in parallel, delivering up to 57.2 kWh for larger homes or off-grid systems.

Indoor vs. All Weather: Key Differences

• Indoor Battery: Optimized for climate-controlled environments, with a sleek design for garages, basements, or utility rooms. Best for homeowners seeking a cost-effective, protected storage solution.
• All Weather Battery: Features an IP65-rated enclosure for outdoor installation, resisting dust, rain, and extreme temperatures (-4°F to 122°F). Ideal for coastal areas, rural properties, or homes without indoor mounting space.
• Why They’re Built for the USA: Both models meet UL standards (UL 9540, UL 1973), ensuring safety and eligibility for the 30% Investment Tax Credit (ITC). With a 10-year warranty and durable LiFePO4 chemistry, they handle diverse climates—from Florida’s hurricanes to Colorado’s snowy winters.

Key Features and Benefits of the EG4 WallMount Battery

Both EG4 Wallmount Batteries share cutting-edge features that make them standouts for solar enthusiasts, with slight variations for their environments.

High-Efficiency Energy Storage

Benefit: Store surplus solar energy for nighttime use or outages, potentially slashing bills by 50-70% in high-rate states like California. For example, a typical household could save $1,000-$1,500 annually by using stored power during peak evening rates.

Smart Battery Management System (BMS)

Benefit: The advanced BMS monitors overcharge, over-discharge, and thermal conditions, ensuring safety and performance. The EG4 mobile app lets you track charge levels, usage, and system health in real time, whether the battery is indoors or braving the elements outside.

Scalability and Longevity

Benefit: Both models offer 6,000+ cycles at 80% depth of discharge, translating to 15+ years of reliable service. Their modular design allows you to add units as energy needs grow, making them future-proof for expanding households or off-grid setups.

Seamless Integration with EG4 Inverters and the GridBOSS MID

The EG4 Wallmount Batteries unlock their full potential when paired with other EG4 products, creating a robust solar ecosystem for your home.

Tie to Existing Content

As we covered in our guide to EG4 inverters, combining inverters with storage transforms your solar system into a powerhouse. Both Wallmount Batteries integrate seamlessly with EG4’s hybrid inverters for optimized energy management.

Inverter Synergy

With 48V architecture and built-in communication protocols, the Wallmount Batteries ensure smooth operation with EG4 inverters. Excess solar power is stored during the day and discharged strategically to avoid costly grid purchases, perfect for time-of-use rate plans.

Spotlight on EG4 GridBOSS Microgrid Interconnect Device (MID)

• What It Is: The EG4 GridBOSS MID is a smart switch that manages multiple energy sources—solar, grid, generator, and battery—to create a home microgrid.
• Benefits: It enables whole-home backup, automatic failover during outages, and code-compliant paralleling for larger systems. This is critical for regions like Florida (hurricanes) or California (wildfires), ensuring uninterrupted power. It also supports net metering and time-of-use savings.
• Integration Example: Imagine your solar panels charging either Wallmount Battery during the day. When the grid fails, the GridBOSS MID switches to battery power instantly, keeping essentials like refrigeration or medical devices running. Paired with an EG4 inverter, this setup delivers a code-compliant, user-friendly microgrid for any USA home.

Spotlight on EG4 Conduit Box

• What It Is: The EG4 Conduit Box (available in indoor and all-weather variants) is a buildable enclosure that houses and protects AC, DC, and PV wiring between your Wallmount Battery and EG4 inverters, ensuring a clean, NEC-compliant installation.
• Benefits: It simplifies wiring with pre-punched knockouts for models like the 18kPV, 12kPV, or 6000XP, reducing installation time, costs, and risks of damage or exposure. Multiple knockouts allow flexibility for custom setups or non-EG4 components, while grommets and plugs maintain weatherproofing for outdoor use.
• Integration Example: Mount the Conduit Box between your Wallmount Battery and inverter for a streamlined conduit run. This is ideal for multi-battery arrays or exposed outdoor systems. It pairs perfectly with the GridBOSS MID for a fully enclosed, professional-grade microgrid.

Installation, Maintenance, and Real-World Applications

DIY vs. Pro Installation

Both Wallmount Batteries are designed for easy installation with basic tools (drill, level, wrenches). The Indoor model fits neatly in sheltered spaces, while the All Weather model’s rugged enclosure simplifies outdoor mounting. Add the EG4 Conduit Box for secure wiring transitions—its buildable design accommodates custom knockouts. For hands-on homeowners, our DIY solar kits make installation even easier, bundling the Wallmount Battery, Conduit Box, and compatible EG4 inverters with step-by-step guides tailored for beginners. These kits simplify setup while ensuring NEC compliance. However, we recommend certified installers for complex systems or to maximize incentives like the ITC. Watch for pitfalls like improper wall anchoring or insufficient clearance for ventilation.

Maintenance

Thanks to LiFePO4 technology, both batteries are low-maintenance—no water checks needed, unlike lead-acid systems. Firmware updates via the EG4 app keep performance optimized, and semiannual checks for dust or loose connections ensure longevity.

Real-World Applications

• USA Example 1Texas Savings: A Houston family with the Indoor Wallmount Battery saves $1,200/year by storing solar energy and avoiding ERCOT’s peak rates.
• USA Example 2: Florida Resilience: A Tampa household with the All Weather Wallmount Battery powers through 48-hour hurricane outages, keeping lights and fans operational without a generator.
• Cost-Benefit Analysis: Installed costs range from $8,000-$10,000 (before incentives), with payback in 5-7 years in high-rate states, factoring in the 30% ITC and local rebates (visit DSIRE for details).
