Growatt SPE 12000 12kW Off-Grid DIY Solar Kit | 14.24kW Array (32x 445W) + 20.48-30.72kWh Battery

Product Overview

The COMPLETE GROWATT SPE 12000 HEAVY-DUTY DIY OFF-GRID SOLAR KIT (120V/240V) is engineered for large off-grid homes, commercial workshops, agricultural facilities, and off-grid estates requiring total power independence. Delivering 12kW of continuous 120V/240V split-phase power, this ultimate off-grid package combines robust power conversion, modular cobalt-free LiFePO4 lithium storage (ALP 5.0L-E2 US), ground mounting accessories, and an expansive 14.24kW bifacial TOPCon solar array.

Key Performance Highlights

• Full 12kW Continuous Power: Transformerless SPE 12000 US inverter providing 12,000W continuous 120V/240Vac split-phase output. Capable of running AC units, heavy 240V well pumps, and workshop machinery simultaneously.
• Massive 18,000W PV Input Capacity: Dual independent MPPT controllers supporting up to 18,000W of total DC solar input (9,000W per MPPT) with a maximum PV input voltage of 550Vdc.
• High-Capacity ALP LiFePO4 Storage: IP66/NEMA Type 4X rated cobalt-free LiFePO4 modules (5.12kWh / 51.2V / 100Ah per module) with a 10-year warranty. Includes heavy-duty floor base stand and primary power interconnect cables.
• 14.24kW Bifacial TOPCon Array: 32x Talesun 445W dual-glass N-Type TOPCon panels delivering up to 20% additional power generation gain from the rear side.
• 70A Generator & Grid Passthrough: Integrated 70A passthrough with automated generator auto-start support for fail-safe emergency backup charging.

Battery Storage Sizing Guide

• 20.48kWh (4x ALP 5.0L-E2 Modules): Entry threshold required to release maximum continuous discharge output for 12kW power loads.
• 25.60kWh (5x ALP 5.0L-E2 Modules) ⭐ RECOMMENDED: Perfect balance for whole-home overnight backup running multiple 240V heavy loads.
• 30.72kWh (6x ALP 5.0L-E2 Modules): Ultimate off-grid energy storage for extended multi-day resilience and heavy daily power demands.
