What are the benefits of a solar battery?
The purpose of a solar storage battery is to keep the excess power your solar panels generate for another time when your household needs to most; maximising your household consumption of solar power.
By using more of your solar you will be reducing your network costs, controlling when you use power and how much you pay for it.
With backup solutions available you can keep the lights on if you lose power. Providing stored power to necessary appliances such as your fridge, lights and Wi-Fi you can have peace of mind during power outages.
How do I choose the right battery size for my home?
With so many sizes, brands and setups on the market to is hard to know what you need, especially in a relatively new market. There are a couple of key figures you will need to know to evaluate your household energy needs and storage capacity suitability:
- Size of your current solar PV system
- The amount of energy your household is consuming and at what times of day is it being consumed
- Your feed-in-tariff (FIT)
- The appliances you regularly use and when
By identifying household consumption and patterns compared to the solar PV system generation, allows the gap to be recognised and a clear battery recommendation to be made. With the wide variety of battery capacities and systems available it is easy to set up a system to make your house run as efficiently as possible.
This analysis can be done over the phone with the assistance of your latest electricity bill. For further information please contact our Customer Care team on 1300 28 29 30 for an individualised solution.
How can I monitor my battery and energy usage?
The use of an energy management system can help you monitor when you're using power from your solar PV system, from the battery and from the grid. Helping you control your energy usage and stepping closer to neutralising your bill.
You can monitor your battery, solar generation and energy usage of your Enphase battery with the Enphase Envoy-S monitoring system – My Enlighten.
For other batteries, carbonTRACK monitoring system can be used, not just for energy usage, but for total home energy management control your appliances and energy even when on the go.
Tesla provides an App to easily track where your power is coming from, when it is being used as well as an average daily self-sufficiency, so you can see your reduced reliance on the grid.
All mobile applicable, you can monitor what’s going on at home, anytime from anywhere.
Can I save money with a battery?
By using more of your solar generated power instead of sending it back to the grid at a low tariff (FIT) and paying peak rates when the sun goes down, a solar battery will save you money from day one.
A lot of households across Australia are not home during the day or at least use minimal power during this time. Unfortunately, this is when your solar panels generate power. With a solar battery you can keep this power for when you get home and need it the most.
Additionally, this means you are using your stored power instead of paying higher peak rates through the evening.
Is solar battery storage safe?
Yes they are. Although the solar battery industry is new, many of the companies manufacturing them have been working with batteries for countless applications since the invention of the battery itself. When installed by a certified solar technician you can have peace of mind your home and family are safe.
The Enphase system is one of the safest systems out on the market now. The battery has Prismatic cells that are highly stable over time and is not a high voltage DC in system. The cell is safety-tested and certified by TÜV Rheinland.
LG Chem regularly test their batteries in the most extreme conditions including temperature, fire and impact with nothing but positive results. With a patented design, LG batteries are developed to maintain their integrity.
Tesla Powerwall’s use the same technology tested in the Tesla vehicles. If they are safe on the roads they are safe on your wall.
Can I connect a solar battery to my current solar PV system?
Yes you can. A solar battery can be added to your existing solar PV system and with so many brands, capacities and systems available it is easy to find the best solution for your set up and household's need.
On some occasions accessories may be needed to be connected to ensure compatibility of the solar PV and battery systems, however no modifications are required to the current system.
Can I go off-grid?
The short answer to this question is that unless your electricity usage is minimal (around 5-15 kilowatt-hours per day), it’s not very easy to disconnect from the grid and still have all the comforts (and/or necessities) you’re accustomed to.
Additionally, in most metro areas a grid connection is required for occupancy. This is why we focus on neutralising our customers’ bills, helping them reach a minimal payment to their utility provider with a maximised use of their own solar produced.
How long does a charged battery last?
A fully-charged medium-sized system could store sufficient energy to power your lights and lower-powered items like your fridge-freezer, TV and laptop during the evening. Over four or five hours, all of these together will use at most a few “units” or kiloWatt-hours (kWh), of electricity.
