Battery

Your typical rooftop solar power system collects energy from the sun via your solar panels, then your inverter turns it into usable electricity. If you generate more electricity than you need, you have extra and can sell it back to the grid at a lower rate than you’d buy it for, or you could feed it into a battery to be used at night.

A solar battery stores the excess electricity from your solar power system allowing you to use the power to save, plus have a backup if the grid is down to power your fridge and lights.

If you don’t have access to electricity via the grid (off-grid), the solar and battery combination can be your primary electricity supply. An off grid system can be designed to suit your needs.

Tesla Powerwall

Tesla Powerwall is a battery that stores energy, detects outages and automatically becomes your home's energy source when the grid goes down. With a usable energy capacity of 13.5 kWh the powerwall will supply power at 7kW peak / 5kW continuous with seamless backup transition of a pure sine wave output. Unlike generators, Powerwall keeps your lights on and phones charged without upkeep, fuel or noise. Pair with solar and recharge with sunlight to keep your appliances running for days.

Powerwall reduces your reliance on the grid by storing your solar energy for use when the sun isn’t shining. The Tesla Powerwall is an AC coupled system which means it can be connected to any existing solar system.

AlphaESS Battery System

The AlphaESS SMILE series provides an all-in-one solution which includes a hybrid inverter, a battery management system and a storage unit in which ‘modules’ of battery capacity can be added. The hybrid inverter enables solar power to be used directly in the household at the time of creation or to charge the battery and enables battery power to be converted to usable AC power.

The storage units can be filled with different battery modules meaning the AlphaESS is one of the more flexible solutions in terms of the storage capacity. For example the SMILE5 series comes with a 5kW hybrid inverter and can be filled with 4 different capacity batteries ranging from 2.9kWh to 13.3kWh, expandable to 80kWh.

This AlphaESS battery consists of lithium iron phosphate (LiFePO4), as the cathode material and its anodes are carbon. Lithium iron phosphate batteries are considered a safer option to Lithium Ion, due to the lithium phosphate holding a high chemical and thermal stability. They are non-flammable meaning they can handle higher temperatures from a short-circuit or overcharge. This makes them an economically sound battery choice, as the

lithium iron phosphate has a longer life cycle compared to lithium ion.

The AlphaESS solution is capable of providing green power to a home or

business during a black out, Importantly the technology is built in so there are no additional costs or extra components required for this capability as is the case with some other batteries.

If you already have solar panels and an inverter, the battery can be

AC-coupled to work harmoniously with your current system. More on this below.

Warranty - The warranty for the inverter and everything that isn’t a battery module is 5 years. The warranty for the batteries is better and promises they will retain a minimum of 80% of their original capacity after 10 years.
