Capacity
The Enphase IQ 5P has a storage capacity of 5 kWh, while the Tesla Powerwall 3 offers 13.5 kWh. Looking at it, it seems that the Tesla Powerwall has more capacity, which makes it a no-brainer for homeowners and business owners looking to power their homes during an outage. On the other hand, the IQ 5P features a stackable design to allow homeowners to build a modular storage system. It’s ideal for those who want to get “just the right” capacity for their home.
Although a single Powerwall can handle a higher peak compared to a single IQ 5P, getting two 5Ps can double the peak and get a more sustained draw from 2 5P batteries. It’s also worth noting that the Tesla Power 3 is a hybrid inverter battery that is only suitable for new solar systems.
Battery chemistry
The Enphase IQ 5P battery is equipped with a LiFePO4 battery, while the Powerwall 3 has a Lithium-ion battery. This makes Enphase a more suitable option as LiFePO4 batteries are safer due to the strong covalent bonds between the iron, phosphorus, and oxygen atoms in the cathode. It makes the bonds more stable and less prone to thermal runaway and overheating. On the other hand, lithium-ion batteries have a reputation for a higher risk of battery fires.
Warranty
Enphase offers a 15-year limited warranty, which is five years longer than Tesla’s 10-year warranty. This provides greater peace of mind knowing your battery is covered for a longer period.
Customer support
In any product that you purchase for your home, especially one that relies on technology and power, you want to be able to reach out to customer support easily. Enphase has an excellent customer service compared to Tesla. For one, Enphase is solely focused on solar energy products, while Tesla has a broader range. Therefore, this allows Enphase to dedicate more resources and expertise to customer service for their solar products.
Additionally, Enphase is a smaller company compared to Tesla. Smaller companies are often more responsive to customer needs. Finally, Enphase relies on a network of certified installers. These installers might have a more personalised touch in dealing with customer concerns compared to potentially larger-scale interactions with Tesla.
