Irish Residential and Small Commercial User Energy Storage Solution

Building Distributed Energy Assets with High Stability and High Self-Consumption Rate

To address the challenges in Europe, such as electricity price volatility, unstable power supply, and increasing renewable energy penetration, GSL ENERGY has delivered a smart distributed energy solution covering the entire chain of "generation, storage, and control" for users in Ireland. The core of the project utilizes a 20 kWh stackable battery storage system (stacked 5 kWh modules), paired with 20 Bluesun 450 W high-efficiency mono-crystalline PV modules and a Solis hybrid inverter. This configuration maximizes self-consumption, enables profit from peak-valley arbitrage, and provides whole-house backup power capability during grid outages.

1. Energy Storage Solution Composition

1.1 Energy Storage System - GSL ENERGY 20kW Stackable Battery Unit

4 x 5 kWh LiFePO4 storage modules

Stackable structure for fast deployment and flexible future expansion

Utilizes high-safety LFP cells, with a cycle life of over 6500 cycles

Single system supports multiple parallel connections to meet future capacity upgrades

Built-in smart BMS for full battery life cycle management

Strong whole-house backup capability, resistant to high load impacts

Compatible with mainstream European inverters (e.g., Solis / Deye / Victron)

1.2 Photovoltaic System | 20× 450W Bluesun PV Panels (9kWp)

Option of high-efficiency mono-facial or bi-facial modules

PID suppression technology ensures long-term stable performance

Resistant to salt mist, ammonia, and sand dust, suitable for Ireland's climate

Stable output and high conversion efficiency

1.3 Solis Hybrid Inverter

Integrates PV MPPT + battery management + grid-tie control

Dynamically switches between off-grid and on-grid modes with millisecond-level response

Supports multiple scenarios: self-consumption, EPS backup, peak shaving

Supports remote monitoring (APP / Web)

2. Solution Value Proposition | Energy Asset Upgrade for Homes and Small Businesses

2.1 Enhance Energy Independence, Reduce Grid Reliance

The 9 kWp PV array can generate power continuously under most sunny/overcast conditions. Coupled with the 20 kWh storage battery, which stores energy during the day for use at night, it significantly increases the self-consumption ratio, potentially reaching 70%–90%.

2.2 Lock in Household Electricity Costs, Build a Stable Energy Budget

With electricity prices in Ireland continuously rising, the energy storage system, through its peak-shaving and valley-filling strategy, can effectively stabilize electricity expenses and offer greater economic benefits as future prices continue to increase.

2.3 Power Outage Protection, Ensuring Continuous Operation of Critical Home Loads

The system provides whole-house backup at any time. Even during grid fluctuations or blackouts, critical loads (such as refrigerators, lighting, network equipment, and heat pumps) can be powered continuously.

2.4 Fast Deployment, Suitable for Both Old and New Buildings

The stackable structure requires no complex brackets, cabinets, or additional foundation work, facilitating quick deployment in traditional European homes.

2.5 Smart Energy Management, Future-Oriented Energy Asset Operation

Automatic distribution of PV → Storage → Loads

Real-time monitoring of power generation, electricity consumption, and charge/discharge curves

Scalable application, supporting future integration of equipment like EV charging piles and heat pumps
