Looking for backup power or wanting to go off-grid but don’t know which solar battery is right for you? If you are a homeowner in Texas or Colorado looking for a solar plus battery storage system, why wouldn’t you want the local solar experts to help you assess solar battery storage options like the Tesla Powerwall and Enphase Encharge batteries?
Well, CAM Solar is here to do just that. We are a Tesla Powerwall installer and an Enphase Encharge installer in Denver, Colorado Springs, and Fort Collins, CO, as well as San Antonio, and Austin, TX. Let’s size up the difference between Tesla Powerwall and Enphase batteries to see which one might work best for your home.
Comparing Solar Battery Features & Capacity
There are a few specifications to look at with each solar battery:
Constant output power rating
Available surge rating
Total battery capacity
The constant output refers to the amount of solar energy the battery in question can send to your home.
The available surge rating describes how much energy the battery can handle when it comes to larger startup electricity draws, like an AC air compressor or any appliance that utilizes a motor.
Additional features can include how each battery is charged by your solar panels, the overall look, and the price.
The Enphase Encharge is rated for the following:
3.84 kW continuous AC Power
5.7 kW surge/peak
10.5 kW total capacity
10 year warranty
To put this into perspective, this continuous power rating is more than enough to power your essential home appliances for about 24 hours (lights, refrigerator, medical equipment, phone chargers, etc). You can combine multiple Enphase batteries to increase your overall power capacity, but perhaps the most important feature of Enphase batteries is their ability to run in parallel with the microinverters and solar panels. This allows your solar panels to directly power your home while also charging your batteries.
The Tesla Powerwall is rated for the following:
5 kW continuous AC Power
7 kW surge/peak
13.5 kW total capacity
10 year warranty
As you can see, Tesla Powerwall provides a higher overall capacity for solar energy, which should similarly cover your emergency electricity needs for 24 hours or more. However, Tesla Powerwall batteries use split-phase operation, so you will not be able to use the energy coming from your solar panels while also pulling energy from your Tesla battery. Once the battery drains to 60%, it then allows for recharging from your solar panels.
What About Cost?
Of course, the bottom line for many homeowners when it comes to solar battery storage installation is cost. How do these compare? Surprisingly, the Tesla Powerwall, touting a larger total capacity and a sleek design, costs 10% to 20% less than its Enphase 10 counterpart. However, depending on how you plan to utilize your new renewable energy system should always be taken into account and here at CAM, we can provide you with an estimated cost for your solar plus solar battery system.
If you are planning a system designed to maximize your solar energy, eliminate most of your energy costs, avoid time of use rates, and keep the lights on during a short power outage, or to fully take your home off the grid, talk to CAM Solar if Tesla Powerwall or Enphase Encharge is right for you.
