10kW/15kWh Residential Energy Storage System in Jamaica

1. Project Overview

Sano Energy deployed a 10kW/15kWh all-in-one residential energy storage system in Jamaica. Equipped with intelligent energy management capabilities, the system delivers autonomous, reliable, and sustainable power supply solutions for household users. It effectively reduces residential electricity expenses through optimized energy utilization. Meanwhile, it provides critical emergency backup power during grid instability or power outages, solving local household power consumption pain points and improving the stability and economy of residential energy use.

2. Project Details & Application Scenarios

The all-in-one residential energy storage system supports multiple intelligent operation modes, adapting to diverse local household power consumption needs and maximizing the utilization efficiency of photovoltaic power resources. The core application scenarios are as follows:

• Self-consumption & Surplus Power Feed-in: The system prioritizes consuming on-site generated photovoltaic power for household use. Excess electricity can be automatically fed back to the public grid, fully tapping the value of photovoltaic power generation and reducing energy waste.

• Automatic On/Off-Grid Switching: It supports seamless and uninterrupted switching between grid-tied and off-grid operation modes. The system can intelligently identify grid operation status to ensure zero power interruption for household loads and deliver a consistent power supply experience.

• Emergency Backup Power Supply: In case of sudden grid power failures or blackouts, the system automatically switches to off-grid backup mode to maintain continuous power supply for key household electrical equipment, guaranteeing basic residential power demand and living stability.

• Time-of-Use Energy Management: Adopting peak shaving and valley filling strategies, the system stores electricity during off-peak tariff periods and releases power during peak tariff periods. It effectively optimizes household power consumption structures and significantly reduces overall electricity costs.
