Tesla Powerwall is an integrated battery system designed to store solar energy for backup power. It ensures that your appliances keep running even during grid outages, thanks to its ability to detect outages and recharge with sunlight. On the other hand, Generac PWRcell offers a powerful and flexible home energy system that can save you money on energy bills and keep your home powered during grid disruptions. Its compatibility with different climate types makes it a versatile option.
When it comes to size, Tesla Powerwall weighs 276 pounds and has dimensions of 45.3 x 29.7 x 6.1 inches, suitable for both indoor and outdoor use. Generac PWRcell, on the other hand, consists of a battery cabinet weighing between 280 and 445 pounds, with dimensions of 22 x 10 x 68 inches, and an inverter unit weighing 62.7 pounds, with dimensions of 24.5 x 19.25 x 8 inches.
In terms of battery types, Tesla Powerwall utilizes a rechargeable lithium-ion battery with a liquid thermal control, specifically a lithium nickel manganese cobalt oxide (NMC) battery. Generac PWRcell, on the other hand, comes with multiple lithium modules in each battery cabinet, allowing for scalability and the ability to add more modules as needed.
Both Tesla Powerwall and Generac PWRcell are designed for use with grid-tied solar and storage systems, providing backup power during grid outages. However, they are not compatible with off-grid systems.
Monitoring and control apps are essential for efficient energy management, and both Tesla and Generac provide easy-to-install mobile apps. Tesla’s app allows you to monitor your energy storage and usage, as well as download solar production and battery usage data. Generac’s PWRview app offers detailed forecasting, bill tracking, and goal-setting for energy consumption.
When it comes to maximum continuous power, Tesla Powerwall offers 5kW, while Generac PWRcell provides 9kW, making Generac more suitable for running larger appliances that require more power.
Capacity is another important factor to consider. Tesla Powerwall has an energy capacity of 13.5 kWh, with a round trip efficiency of 90% and a depth of discharge of 100%. Generac PWRcell, on the other hand, offers a capacity of up to 18 kWh, with a round trip efficiency of 96.5% and a depth of discharge of 84%.
Warranty is a crucial aspect when making a significant investment like a home battery system. Tesla Powerwall offers a 10-year warranty with a guaranteed 70% end-of-warranty capacity, ensuring peace of mind for homeowners. Generac PWRcell also provides a 10-year warranty, but it does not guarantee any battery capacity at the end of the tenure.
Cost is an important consideration for many, and Tesla Powerwall is priced between $12,850 and $73,300, depending on the number of batteries installed. Generac PWRcell’s basic model starts at around $10,000, with scalability options available for larger systems.
In summary, both Tesla Powerwall and Generac PWRcell are reputable batteries for home solar energy backup systems. Tesla Powerwall offers a more robust and complete solution, backed by a trusted brand. However, the choice between the two ultimately depends on individual preferences, the size of the solar energy system, and future scalability plans.
