HomeGrid Stack’d Series 14.4 kWh Lithium Battery System

Name: HomeGrid Stack’d Series 14.4 kWh Lithium Battery System
SKU: HG-STACK-14.4-BAT-SYSTEM

SKU HG-STACK-14.4-BAT-SYSTEM

The HomeGrid Stack'd Series 3-Module configuration provides 14.4kWh of usable energy storage with 12.9kW continuous power output for residential backup applications. Lithium iron phosphate chemistry delivers superior cycle life and thermal stability compared to cobalt-based alternatives. This mid-range configuration supports most home backup requirements including HVAC, refrigeration, lighting, and electronics while maintaining capacity for daily solar self-consumption cycles.

Modular architecture enables installation in under 30 minutes with tool-free module connections and no inter-module wiring. Compatible with Sol-Ark, and Solis inverters via CAN / RS485 communication protocol. System scales to 15 Stacks in parallel for up to 576kWh total capacity, providing flexibility for multi-family or small commercial projects.

HomeGrid 3-Module Configuration Features

Rapid Installation: Tool-free connections between BMS base and battery modules eliminate conduit work and reduce installation time to under 30 minutes per Stack
Residential Backup Capacity: 14.4kWh can handle essential backup loads while maintaining low upfront investment for budget-conscious projects
High Power Output: 12.9 kW continuous output supports demanding household loads and enables operation of large appliances, including air conditioning, when paired with a compatible inverter.
Future-Proof Expandability: Add modules to existing Stack (up to 8 modules total) or parallel additional Stacks without rewiring or system reconfiguration
Enhanced Safety Profile: Cobalt-free LFP chemistry eliminates thermal runaway concerns and operates at low voltage for simplified permitting and reduced safety requirements

Stack'd Series 14.4kW Configuration Technical Review (3 Modules)

Installation completes in under 30 minutes per Stack using tool-free vertical stacking on the gray base stand, which elevates modules 7.75 inches above floor level for protection against standing water. The BMS integrates detection mode DIP switches to automatically recognize connected modules during power-on sequencing from bottom to top.

Communication with hybrid inverters requires CAN bus wiring through the INV-CAN port, with pre-configured cables for Sol-Ark installations. Parallel expansion capability supports up to 15 Stacks using Link A to Link B daisy-chain configuration with standard Ethernet cables between BMS units. Battery terminal connections demand 4/0 gauge cabling within 20-foot runs to minimize voltage drop, secured with M8 hardware at specified torque values. Field expansion adds modules to the top of existing Stacks without DIP switch reconfiguration of original modules, maintaining the bottom-up addressing convention that simplifies future service and capacity upgrades.
