Solar Battery Alternatives to the Tesla Powerwall
Tesla Automotives is one of the biggest electric car manufacturers in the world – leading the way for clean energy vehicles and companies to make a stand against climate change. However, there is something that Tesla is also a proud partner of – and that would be energy storage. Tesla’s Powerwall is a solar battery storage system that stores any of the unused energy that was produced by your solar panels throughout the day – so you can use it at night or in the case of an emergency.
Its second iteration, the Tesla Powerwall 2– delivers up to two times more energy density than the original, and serves as Tesla’s champion in the industry of energy storage.
Before we start looking at alternative battery systems let’s go through some key features of the Tesla Power Wall 2.
Storage: It has a full usable storage capacity of 13.5kwh which for most homes is enough to provide power for the entire night.
Backup: When you lose power from the grid the Tesla Power Wall 2 can provide a continuous 5kw of power and a maximum of 7kw for 10s. This gives you the ability to have full home backup when you need it. If you pair the Tesla Power Wall 2 with a suitable solar inverter it can still charge your battery when there is no power from the grid. Potentially you could have your home powered for days and days just from your battery.
Connectivity: The Tesla Power Wall 2 has all the bells and whistles when it comes to the monitoring app. It can communicate via a direct connection to your modem or WIFI. It also comes standard with a 4G sim card to make sure you never lose connection with your home battery.
In this article, we’re going to be taking a look at a couple of alternatives that can stand up to the Tesla Powerwall 2.
Reasons for Using A Solar Battery
1. Backup Power in the case of Emergencies
The biggest reason many homeowners have an energy storage system alongside their solar energy system is for the off chance of blackout. Certain areas are more prone to blackouts and natural disasters, and on the chance that either of those two things happens, having an energy storage system will allow for you and your family to stay safe and warm until emergency services show up.
An energy storage system doesn’t require gas to be utilised and can power a home for up to three days without fail. It’s an extra level of safety that many homeowners don’t know about.
2. Energy Independence
Energy storage systems can also power your home during the night time when your solar panels can no longer produce energy. The best part about this is, by becoming fully energy-independent, you will no longer have an electric energy bill.
You can stop relying on your utility company’s electrical grid, and you will have effectively reduced your home’s carbon footprint to zero.
3. Long Term Savings
While the initial investment may seem steep, removing the ongoing cost of energy bills means that you can save that money for other expenditures within or around your home. Or alternatively, you can pool the money you have saved into other investments or on a fun vacation. You’re going to be saving a lot more money in the long run, even more so than by just switching to solar.
Alternatives to the Tesla Powerwall
The Senec Home V3 Hybrid
One of the biggest reasons why the SENEC Home V3 hybrid battery is better than the Tesla Powerwall is its versatility. The Tesla Powerwall only works best when it is paired with an external inverter to connect to solar panels. SENEC V3 uses an “all-in-one” hybrid energy transfer system, that can be utilised with any brand, and any type of panel.
On top of that, the SENEC V3 also has a higher maximum hybrid power output system than the Tesla Powerwall – Tesla is not flexible it can only store or the home can use 5kw at any time, the SENEC can store 3 kW of solar into the battery and you can use up to 5kw in your home
Founded in 2009 and made in Germany Senec produce high-quality battery storage systems. As far as product warranties go – the SENEC V3 also beats out the Tesla Powerwall by ten years. The SENEC V3 comes with an optional 20-year warranty, while the Tesla Powerwall only has a ten-year warranty.
If you’re looking for an energy storage system that can be used with any sort of solar panel and solar energy system with a long warranty – the SENEC V3 would be the right choice for you and your family.
By the way, the SENEC V3 costs only about 70% of what the Tesla Powerwall 2 costs – so you’re saving money, while also getting a better battery.
The Alpha ESS Home Batteries
Alpha ESS batteries have a very peculiar feature that can bring back even more money to you than a Tesla Powerwall can. It does everything the Tesla Powerwall does, including having a mobile app and Smart technology that allows you to control the flow of the energy from the Alpha ESS battery to your home. Let’s just say one day – you’re having an excess of energy-driven into your Alpha ESS battery. Instead of letting that energy linger and go to waste, Alpha ESS home batteries will actually send the excess energy to your utility grid.
By having a Net Energy Meter – your utility company will send you a credit, which is money that you can use for whatever you need.
Another great feature that the Alpha ESS batteries have is their built-in 4.6-kilowatt hybrid inverter. By having a built-in inverter within your energy storage system, there will be less resistance loss, meaning that you will absorb more energy into your home, and into your battery from your solar panels.
The Tesla Powerwall is just an energy storage system, and you will need to connect your own inverter into it, which can vary in price depending on the inverter you have.
Alpha ESS batteries also have a ten-year warranty, just like the Tesla Powerwall.
The Tesla Powerwall may sound cool and amazing, but there are equal alternatives like the SENEC V3 and the entire line of Alpha ESS home batteries. Both are more suited to other branded solar energy systems and have additional properties that either make them more energy-dense than the Powerwall.
Furthermore, these batteries are less than 75% of the cost of Tesla’s Powerwall, leaving you with more money in your wallet.
