Philippines 15KW Off-grid Energy Storage Project

This Philippines 10kW/15kWh off-grid home energy storage project is designed for self-generation and self-use. The system combines a 10.2kW off-grid solar inverter and a 15kWh lithium energy storage system to deliver reliable, independent power for Filipino households — storing daytime solar energy for night-time use and ensuring continuous supply during grid outages.

System Configuration

System Components

1. 15kWh Energy Storage Battery

The 15kWh lithium battery system stores daytime solar energy for night-time self-consumption and backup. Built-in BMS monitors battery status and ensures safe, stable operation. Long cycle life, modular design for flexible expansion. 3-year warranty, CE / IEC / UN38.3 certified. View product details →

2. 10.2kW Off-Grid Solar Inverter

The 10.2kW off-grid inverter manages solar generation, battery charging and household load supply independently. Pure sine wave output supports everyday appliances with stable, reliable performance in full off-grid operation. 

Why This System Fits Filipino Households

• The Philippines experiences typhoons and grid disruptions — off-grid storage ensures reliable backup power when the grid goes down
• 15kWh capacity stores enough daytime solar energy to support essential household loads through the night
• Self-generation and self-use reduces dependence on rising utility electricity and lowers monthly energy costs
• High solar irradiation across the country provides strong daytime charging for year-round dependable performance

Frequently Asked Questions

How long can the 15kWh battery power a home?

The 15kWh battery supports essential household loads (lighting, refrigerator, fans, TV, phone charging) for roughly 10–18 hours. With heavier loads such as air conditioning, backup time is shorter. Additional battery modules can extend duration.

Can the system handle power outages after typhoons?

Yes. As a fully off-grid system, it continues supplying stored solar power independently when the grid fails, providing reliable backup during typhoon-related outages.

Can battery capacity be expanded later?

Yes. The modular battery design allows additional units to be added, increasing storage capacity without replacing the inverter or rebuilding the system.

What is the warranty for this system?

The 15kWh battery and 10.2kW inverter carry a 3-year warranty. Remote monitoring, spare parts support and technical assistance available for homeowners and installation partners.
