HomeGrid Stack’d 33.6 kWh – (7) 48V Standard All Weather Lithium Battery Modules + BMS & Base
Model: HG-7-Stack • Battery Modules: 4000051 • BMS & Base: 4000044
The HomeGrid Stack’d 33.6 kWh battery system is a powerhouse for whole-home backup, off-grid cabins, and large residential or small commercial solar energy systems. With (7) 48V lithium-iron-phosphate (LFP) battery modules stacked into a single, compact tower, this system delivers exceptional energy storage capacity, rapid charge/discharge performance, and long-term reliability.
Engineered for durability and scalability, the HomeGrid Stack’d series is easy to install, compatible with leading hybrid inverters, and built to power your home during outages or reduce daily grid consumption with clean, stored solar energy.
Key Technology
High-Capacity LFP (Lithium Iron Phosphate) Chemistry
HomeGrid uses premium LFP cells that offer superior safety, thermal stability, and industry-leading cycle life. LFP is the preferred chemistry for whole-home backup due to its non-flammable makeup and long-term reliability.
Modular “Stack’d” Architecture
Seven 48V battery modules stack vertically on a reinforced base and connect to the included BMS (Battery Management System). This allows high usable capacity in a small footprint, easy transport, fast installation, and future expansion.
Advanced Battery Management System (BMS)
The 4000044 BMS ensures balanced charging across all modules, protects against over-/under-voltage, controls thermal regulation, and communicates seamlessly with compatible hybrid inverters.
High Power Output for Whole-Home Loads
Stack’d systems deliver fast discharge rates that support energy-intensive appliances, heat pumps, HVAC, well pumps, and EV charging (inverter-dependent).
Scalable to 80+ kWh
For larger homes or critical commercial applications, multiple Stack’d towers can be combined to create massive storage banks.
Warranty
-
10-Year Manufacturer Warranty
-
Up to 6,000 Cycles depending on usage conditions
-
Performance Guarantee: ≥70% capacity remaining at warranty end
HomeGrid warranties cover manufacturing defects, BMS performance, and cell degradation under standard operating conditions.
