Solution Introduction

SOLUTION INTRODUCTION

Torphan’s residential energy storage system is designed to help homeowners maximize solar energy use, reduce electricity bills, and achieve greater energy independence. Powered by safe, long-life lithium iron phosphate (LiFePO₄) batteries and integrated with an intelligent battery management system (BMS) and solar inverter, the system supports solar self-consumption, peak shaving and valley filling, and backup power supply.
Designed for residential applications across North America, Europe, and Asia-Pacific, the system integrates seamlessly with rooftop solar PV systems to maximize clean energy utilization. When the grid goes down, it automatically switches to backup mode to keep essential household loads, including refrigerators, lighting, and medical equipment, running.
Combining safety, reliability, and cost efficiency, Torphan delivers a smarter home energy solution that helps homeowners lower electricity costs and move toward energy independence.

Application Scenarios

APPLICATION SCENARIOS

Integrated Solar and Energy Storage

Integrates with rooftop solar PV systems to enable self-consumption, energy storage of surplus solar power, and grid export, helping homeowners reduce electricity bills through net metering or applicable net billing programs.

Reliable Backup Power

Provides backup power during unexpected grid outages, keeping essential loads such as refrigerators, lighting, routers, and medical equipment running while minimizing household disruption and potential losses.

Peak-Valley Electricity Arbitrage

Charges during off-peak hours and discharges during peak-rate periods to take advantage of time-of-use electricity pricing, reducing monthly electricity bills and improving overall energy cost efficiency.

Off-Grid Power Supply

Ideal for remote homes, vacation properties, and other locations without grid access. Combined with solar PV panels, the system provides independent power to meet everyday household electricity needs.

Solution Highlights

SOLUTION HIGHLIGHTS

Case Reference

CASE REFERENCE

Residential Energy Storage Project in California, USA Deployed a 48 VDC, 1,120 Ah lithium battery storage system designed to support California’s SGIP incentive program, enabling time-of-use energy arbitrage and backup power. The system helps reduce annual electricity bills by over $800.

Residential Solar + Storage Project in Munich, Germany Integrated with a 6 kW solar PV system, the solution achieves an 85% solar self-consumption rate. Excess electricity is exported to the grid for bill credits, with an estimated payback period of 12 years.

Residential Energy Storage Project in Sydney, Australia Designed to address local grid fluctuations, the system provides up to 10 days of backup power, helping keep essential household loads running during extended outages.
