AlphaESS is a leading solar energy company founded in 2012 in Nantong, China. While still a young solar battery company, AlphaESS products have already been sold to over 50 countries worldwide. With over 10,000 solar products shipped around the globe, AlphaESS has developed a strong international reputation. AlphaESS has partnered with the solar manufacturer EVE. Established in 2001, EVE is a large Chinese manufacturer of batteries for solar products and electric vehicles. Through this partnership AlphaESS has been able to deliver high quality solar batteries. By combining the innovation of Alpha and the large-scale capacity of EVE, Alpha solar batteries are one of the fastest growing solar storage products on the market.
Generate your own electricity and use it whenever you want. By simply adding a SENEC Solar Battery Storage System to your solar panels you can become up to 90% Power Self-Sufficient. Whether you already have an existing PV System or are yet to install one, a SENEC Solar Battery can enable you to use solar power 24 hours a day. SENEC is compatible with all systems, regardless of the manufacturer. A new solar system is best optimised with a power storage, or if you already have solar then it’s easy to retrofit. SENEC gives you the advantage of being able to store the solar energy you generate, rather than feeding it back to the grid for next to nothing. As a result of this, your solar power is available for you even at night which is when most Australians need it most.
The Tesla Powerwall 2 is a solar battery that can store solar energy from your solar panels and use it to power your home. By integrating with your home solar system, the Powerwall 2 stores excess energy throughout the day that you can access when you need it. This stored solar power allows users to power their home, independent from the grid. This independence reduces your electricity costs, your environmental impact and safeguards against blackouts. The Powerwall’s sleek and compact design holds a powerful, rechargeable lithium-ion battery pack. This battery stores solar energy for self-consumption, backup power, load shifting and off-grid energy. Don’t let the slender size of this battery fool you, its fully-integrated AC battery system is suitable for residential use.
Installing a battery will mean that you don’t need to buy as much power from your electricity retailer. Since you’ll be able to use free solar energy generated by your panels during the night as well as during the day. Your home can run off of the solar energy you have stored in the event that the grid goes down.

The energy stored in a solar battery system that can actually be used. In most cases this is less than the nominal storage capacity figure provided. For example, the Enphase AC battery has a total storage capacity of 1.2kWh. But as only 95% of that stored energy can be discharged (aka a 95% Depth Of Discharge) the battery’s usable storage capacity is really 1.1kWh.
Some solar batteries in the table have different warranties for components within the unit. For example, some “all in one” battery storage systems warrant the batteries for 10 years but the internal inverter only has a warranty of 5 years. We use the ‘weakest link’ warranted figure (so in the above example, 5 years instead of 10 years) when calculating the cost per warranted kWh.
This is only using the Electricity generated from your Solar Panels only. Typically in Self Consumption Mode you will do 1 cycle per day. Some Solar Battery Manufacturers like Alpha ESS and Tesla give you better Warranty if you only use Self Consumption Mode. Alpha Energy Storage System has a very strong Warranty. Over 10 years they still Warrant that you will get atleast 80% of the original Solar Battery capacity. This is the point that Alpha Solar Batteries are in big point of difference in value.
The storage throughput is the amount of energy that cycles through the storage bank in one year. Throughput is defined as the change in energy level of the storage bank, measured after charging losses and before discharging losses. This value is used to calculate the life of the storage bank.
The kilowatt hours (kWh) is the amount of stored energy that your battery can hold and use. The total warranted kWh is the number of kWhs a battery can provide per day multiplied by the amount of days given in the warranty period. To determine the cost per warranted kWh, you take the total solar battery price and divide it by the warranted kWh.
In terms of system sizing – battery sizes are expressed as kilowatt-hours, or kWh. If the average home uses 16kWh, 30% of this during the day and 70% at night, that works out to about 5kWh of daytime usage, and 11kWh of night-time usage. So, simple math would dictate that the average Aussie would need about 11kWh of solar battery storage to offset all their night usage. The Tesla Powerwall 2 has 13.5kWh capacity and costs around $15,000, including installation.
This is important when in an event of a power outage you need to consider how much power you will need to run your loads. The larger the KW rating this allows you to have more appliances turn on.
UPS – Means Uninterrupted Power Supply. When the power from the grid turns off the battery will kick in within 30ms. This is so fast that you might not even see your lights flicker.
EPS – Means Emergency Power Supply. When the power from the grid turns off the battery will take up to 1 minute to turn on.
If you installing Solar Panels and your considering adding a Solar Battery Storage System, then you need to consider your consumption profile. Know more about solar battery storage calculator and solar battery price comparisons
