HomeGrid Stack'd All-Weather LiFePO4 Battery Module (Non Heated) Model 4000051
The HomeGrid Stack'd All-Weather Battery Module is a modular lithium iron phosphate (LiFePO4) energy storage solution designed for expanding compatible HomeGrid Stack'd battery systems. Built for residential solar battery storage, whole-home backup power, and off grid energy systems, this battery module makes it easy to increase storage capacity without replacing your existing battery system.
Featuring cobalt-free LFP battery chemistry, a durable all-weather design, and stackable construction, the HomeGrid Stack'd battery module offers a flexible way to build or expand a home energy storage system as your power needs evolve.
Important: This product includes an individual all-weather battery module only. It does not include the required HomeGrid Stack'd BMS/Base, inverter, or additional battery modules. This is the non-heated version; the heated module is sold separately. For heated version go here
Key Features and Benefits
- Expandable Battery Storage: Add battery modules to a compatible HomeGrid Stack'd system as your energy storage needs increase.
- LiFePO4 Battery Chemistry: Cobalt-free lithium iron phosphate technology designed for dependable residential energy storage.
- All-Weather Construction: Durable enclosure protection suitable for approved indoor and outdoor installations.
- Modular Stackable Design: Integrated stacking architecture simplifies system expansion and replacement of individual modules.
- Whole-Home Backup Capability: Supports compatible battery systems designed to power household loads during grid outages.
- Solar Energy Storage: Stores energy generated by compatible solar systems for later use, including evening consumption and backup power.
- Smart Battery Management: Works with the separately supplied HomeGrid BMS for battery monitoring, system communication, and management.
- Long-Term Serviceability: Individual modules can be serviced or expanded without replacing the entire battery stack, subject to manufacturer requirements.
Modular Solar Battery Storage That Grows With You
The HomeGrid Stack'd Series provides a flexible alternative to fixed-capacity home battery systems. Its modular architecture allows homeowners and installers to configure energy storage around the needs of a particular property and expand capacity as those needs change.
Whether you're adding storage to an existing solar installation, increasing backup power reserves, or planning a larger off grid solar system, additional compatible Stack'd battery modules can help extend available stored energy.
Each battery stack operates as an integrated system with its dedicated HomeGrid battery management controller and base. The BMS manages battery operation and communicates with supported inverters.
Designed for Residential Backup and Off Grid Solar Systems
HomeGrid Stack'd batteries are designed for integration with compatible hybrid and battery-based inverters. When configured as a complete energy storage system, they can support applications ranging from solar self-consumption to emergency backup and off grid energy storage.
HomeGrid identifies compatible configurations involving inverter manufacturers such as Sol-Ark, Schneider Electric, SMA, Victron Energy, and OutBack Power. Actual compatibility depends on the inverter model, firmware, battery communications, and applicable system certifications.
Applications
- Residential solar battery storage
- Whole-home and essential-load backup power
- Off Grid Solar System energy storage
- Hybrid solar inverter installations
- Time-of-use energy management
- Expansion of existing HomeGrid Stack'd battery systems
- Replacement of compatible Stack'd battery modules

Frequently Asked Questions
Can this HomeGrid Stack'd battery module operate by itself?
No. This product is an individual expansion module, not a standalone battery system. It must be installed as part of a compatible HomeGrid Stack'd configuration with the required BMS/Base and additional battery modules.
What is the difference between the standard all-weather and heated Stack'd modules?
The standard all-weather module provides environmental enclosure protection but does not include integrated battery heating. HomeGrid offers a separate heated all-weather module for applications requiring that feature. HomeGrid recommends avoiding mixtures of heated and non-heated modules within the same stack.
Can I add this module to an existing HomeGrid Stack'd battery system?
Yes, provided the existing system supports expansion and the module is compatible with its battery generation, BMS, and configuration. Verify firmware requirements and module compatibility before ordering. HomeGrid's battery management system supports module balancing during approved expansions.
Does this module include the HomeGrid BMS and base?
No. The BMS and base are sold separately. If you are building a new Stack'd battery system, you will need the appropriate controller/base and enough compatible battery modules to meet the manufacturer's minimum system configuration.
Is the HomeGrid Stack'd battery compatible with Sol-Ark inverters?
HomeGrid lists Sol-Ark among its supported inverter manufacturers. However, compatibility and UL 9540 certification are configuration-specific. Confirm the exact Sol-Ark model, BMS, firmware, and approved battery configuration before installation.
Can this battery be used in an off grid solar system?
Yes. A complete HomeGrid Stack'd battery system can provide energy storage for a compatible off grid solar system. It requires an appropriately configured inverter and solar charging equipment; the battery module cannot connect directly to solar panels.
Is this a complete home battery backup system?
No. This listing is for the battery module only. A complete backup system also requires the appropriate HomeGrid BMS/Base, additional modules, a compatible inverter, and other equipment determined by the system design.
