Tesla Powerwall vs Enphase Battery


Tesla Powerwall 2 vs. Enphase Battery

How do you choose the right battery for your needs? There is a lot of information out there and unless you’ve done a ton of research and are technically inclined, it might get confusing, not to mention overwhelming. Don’t worry, we’re about to break it down for you. Here are the most important terms in the world of solar batteries and what they mean: in simple terms. You’re welcome.

The depth of discharge (DoD) of a battery simply refers to how long it can keep a charge before needing to be recharged. Take, for example, your cell phone. You’d have a 94 percent DoD if you had to recharge it every time it said 6 percent.

The term “round-trip efficiency” (RTE) simply refers to how much power your cell can deliver vs how much it can save. Using your mobile phone as an instance, the RTE would be 65% if you were only able to utilize 65% of the battery each time you recharged it. This differs from DoD in that it monitors the amount of energy emitted vs the total energy put into it for each phase.

Battery Backup for Solar Panels

What all of this means for you: Because batteries decrease effectiveness with each round (as we all know from our phones), opt for a solar battery with a strong RTE to optimize your benefits and longevity.

Again, because we all know that batteries drain energy with each cycle, battery life and whether or not the vendor offers a guarantee are critical factors to take into account.

Depending on how many cycles a solar battery goes through, it can last anywhere from 5 to 15 years. The majority of leading suppliers provide a 10-year warranty on their batteries.

What this means for you: choose a solar battery from a reputable company with at least a 10 year warranty. That way if anything goes wrong within 10 years, you’ll get a free replacement.
