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.

Additional Installation Items (Not Included)
To accommodate different site layouts and surface types, standard installation hardware is sourced separately based on your specific setup:
- PV Extension Cables: Solar-rated 10AWG wiring to span the distance from your solar array to the inverter.
- Mounting Racks: Roof racking or ground mounts chosen specifically for your installation surface.
- AC/DC Breakers & Switches: Standard circuit breakers, disconnects, and conduit required for your site.
Notice: All installations must comply with local and national electrical codes. Please consult a qualified electrician or solar installer to determine proper wire sizing, fusing, and safety equipment for your specific location.
