Alpha ESS S5 G3
Solar Battery Storage
Alpha ESS is the leading global green energy storage solution for putting the power back in your system and control back in your hands.
Energy storage goes hand in hand with solar PV panels, allowing owners to run their homes and businesses on low-cost, sustainable energy by storing excess solar power generated throughout the day for later use. This smart solution also enables users to produce lower-cost energy by charging batteries overnight during cheaper hourly grid tariffs, maximizing savings and efficiency around the clock.
What is the function of battery storage in a PV system?
Battery storage is used to store excess solar generation for use at a later stage as required. It increases the ability to self-consume power and reduces grid dependence. It results in a higher installation cost but if electricity usage is moderate to high on a property it can greatly increase the potential savings of a PV system.
Battery storage is also used to charge from the grid overnight during cheap rates available from electricity suppliers. This power can then be used during the day when purchasing electricity would be more expensive. This is commonly referred to as “grid shifting”. This function is commonly used during the Winter months when the solar panels aren’t generating enough power to cover the load of the house.
During the summer months when the solar panels are generating enough power to cover the load of the house, with the excess being stored in the battery. You can charge the battery overnight on the cheap night rate and then discharge the battery to the grid, purchasing the power at a cheap rate from your supplier and then selling it back to them receiving more than you originally paid for it.
If you have an appropriately sized PV system kitted to the appropriately sized battery storage system you can expect to see your annual bill decrease by at least 80%.

Alpha ESS Battery Storage
The first Alpha ESS battery storage system was installed in Ireland in 2017 and has since become the battery of choice for thousands of Irish customers, with a 10-year product and performance warranty and it being the only battery system on the Irish market backed by Munich RE, rest assured knowing that your battery system combines market-leading specifications alongside credibility and durability.
The Alpha ESS batteries come in 10.1kWh, 9.3kWh, 4.0kWh and 3.8kWh variations, offering a wide range of capacity options to tailor to the needs of each project.
Alpha ESS battery storage systems offer a compelling package with Irish-based technical support, 10-year warranties, and being proven and established on the Irish market.
The Alpha ESS S5 G3 battery is the flagship storage solution for empowering solar PV systems. It offers many premium features, including modular design, capacity options, and the integration of inverter and battery management systems from a single manufacturer.
Modular Design and Battery Capacity
The Alpha ESS S5 G3 battery system is engineered with a modular architecture, allowing for flexible energy storage solutions tailored to diverse needs. This AlphaESS battery design enables users to start with a base capacity and expand as required, ensuring both scalability and cost-effectiveness.
Battery Management System (BMS) and Inverter Integration
At Solar Home, both the battery and the inverter we use are manufactured by the same, single brand—AlphaESS. This means the BMS (Battery Management System) software, which runs the whole system, is the responsibility of one manufacturer who just so happens to be the premium choice for solar storage energy solutions.
When selecting an inverter battery, it’s essential to consider technical aspects that will determine battery lifespan, durability and efficiency. The S5 G3 battery system advantages include (but are not limited to) power output, battery chemistry, expansion capabilities and its lithium iron phosphate (LiFePO4) composition, known for safety, longevity and thermal stability which ensures the solar energy generated by your PV panels does not go to waste.
Lithium Iron Phosphate (LiFePO4) Composition
The Alpha ESS S5 G3 System can be kitted with up to 10kWp of PV panels which allows you to supply 5kW of AC power and 5kW of DC power simultaneously. It comes with a 10 Year European product and performance warranty with an 80% guaranteed usable capacity on the battery at the end of the warranty period. The Alpha ESS system has been installed on the Irish market since 2017 combining both proven durability and high-performance specifications.
