Tesla Powerwall and Solar Backup In San Antonio
When Go Solar Group first started installing they realized something was missing. People who got solar weren’t getting protected against blackouts.
Many think that they have nothing to worry about when they install solar. This, however, isn’t the case unless you have the right system installed. Now that Go Solar Group has become a San Antonio solar company you can have a system that meets your backup needs.
Residential Solar During Texas Power Outages
Most people don’t realize that their system won’t work in a power outage. This, however, is the case for all solar arrays connected to the grid without solar backup.
Why Solar Arrays Will Turn Off
The reason that solar arrays will turn off in a power outage is simple. Safety. The National Electrical Code requires photovoltaic systems to have a disconnect switch.
Disconnects will interrupt the current coming from your panels. When a current gets interrupted it turns the power off. Disconnects make sure that no one will get electrocuted while fixing grid issues.
The problem is that disconnects disrupt all current coming from your panels. This means that although the sun may be out you still won’t have power.
Solar Backup’s Solution To Power Outages
Go Solar Group sees this issue and as a result provides solar backup solutions for all our customers. With Solar backup, you can redirect your power away from the grid.
Difference Between Battery Backup And Solar Backup In San Antonio
Solar backup is not a new concept. Many are aware that they can get backup for their solar array. The problem is that the only backup option that people are aware of is battery backup.
Although battery backup is currently the best option it isn’t the only choice. And depending on your situation it may not be the most ideal one either.
Solar Backup Isn’t Always Battery Backup
Often solar backup and battery backup get interchanged. This makes backup information confusing for everyone involved.
Battery backup is a form of solar backup. With battery backup, you are able to charge a battery with your excess solar energy. If you have enough batteries you can run your entire home with them when the sun is down.
What Solar Backup Is
Solar backup is any device used to power essentials in the event that your solar array doesn’t work. Most backup options get charged by your excess solar power.
Technically, net metering is a type of backup. You get credited for your excess power so you can pull power off the grid when the sun is down. It, however, isn’t the most dependable backup option.
Go Solar Group Solar Backup Options For Texas Residents
Go Solar Group realizes that each home is unique and not everyone is a good fit for battery backup. That is why we have different levels of solar backup for our customers.
Secure Power Supply(SPS) With SMA Inverters
Every Go Solar customer that has an SMA inverter installed with their solar array can get an SPS. An SPS re-routes your power away from the grid and to an outlet installed near your inverter. Because of this, you may have to connect your fridge or other necessities to it with an extension cable.
An SPS allows you to have power during the day even if the grid is down. Some restrictions apply when using the SPS.
First, you can only use the SPS when the sun is out. This is because the outlet is getting direct not stored power from your solar panels.
The second restriction is how much you can power. SPS is not meant to power your entire home. You can use up to 2,000 watts in a day, but it is dependent on the weather.
Energy.gov has an appliance energy calculator. This calculator helps people determine where their energy use is coming from.
An average TV uses between 80 and 300 watts an hour. Your clothes dryer uses 2,790 watts an hour. Keeping your refrigerator on will use about 225 watts an hour.
As you can see 2,000 watts doesn’t go very far, but it will make a power outage livable. An SPS will keep your refrigerator running and a few necessities charged.
Portable Backup Solar Generator
Go Solar Group sales portable solar generators from Goal Zero. If you would like your solar generator charged by the SPS you should use the Yeti 1400 or Yeti 3000.
The Yeti 1400 will produce up to 1428 watts. The Yeti 3000 produces up to 3075 watts in a charge.
Portable generators weigh about 40 lbs. If you need power brought to you it is a great way to do it. The Yeti has several different ports so you can connect them to your device with ease.
Home Integration Kit (HIK)
The home integration kit gets powered by your choice of Goal Zero generator. It will connect to their Yeti 1000 and above. The Yeti 3000 is the recommended generator because it will produce the most juice per charge.
When you use a home integration kit you can connect up to four 120 volt circuits in your home to their device. This means that you don’t need to unplug anything. All you need to do is turn on your HIK and the lights and outlets on these circuits will stay on.
You will need to decide which circuits would be the most vital to you in an outage. Goal Zero suggests powering your fridge, garage door opener, WiFi router, and some lights.
When planning which circuits you will keep turned on make sure that it won’t drain your Yeti in a couple hours. Pay attention to everything that the circuit powers. You can monitor your energy use with the yeti mobile app.
Battery Backup For Your Home: Tesla Powerwall
Go Solar Group is also a certified tesla installer. The Tesla Powerwall can power your entire home. In the Powerwall spec sheet, the powerwall weighs 276 lbs and can be mounted on the wall or the floor.
Each battery can power up to 14,000 watts in one charge. However, if the powerwall has continued use it will power up to 5,000 watts between charges.
How many Powerwalls you need depends on if you want to power your whole home. Tesla recommends that you get 2 Powerwalls if you use 30 kWh per day on average and are planning on continuous use.
30 kWh may seem small, but it is equivalent to 30,000 watts. You will need to look at your monthly usage on your power bill to determine how much power you regularly use.
