12kW Split Phase Solar System For Home

Project Overview

This Jamaica home project was planned around a detailed household load list, 120/240V split-phase service, frequent outages, and the customer’s backup priorities. The configuration combined a 12kW inverter with a 7.2kWp solar array and 48V lithium storage.

System Configuration

• Solar panels: twelve 600W monocrystalline modules, providing 7.2kWp of nominal solar capacity.
• Inverter: one 12kW 48V split-phase hybrid inverter with 120/240V output.
• Battery: one 48V 330Ah lithium battery.

Load Planning

The system was selected around the stated household loads, including air conditioning, refrigeration, a water pump, lighting, and everyday appliances. These loads may not all run at the same time. Final operation depends on simultaneous demand, motor and compressor starting power, solar production, battery settings, and installation conditions.

What This Example Shows

This configuration is a useful reference for larger homes and villas using 120/240V split-phase power. Send us your load list, electricity bill, required backup time, and installation details so we can size a system for your property rather than relying on this example alone.
