To figure out the very best battery for your solar panels search for high round trip efficiency (RTE), long cycle life (life expectancy), and a flat voltage curve (functional energy). A more effective battery with a flat voltage curve will permit you to utilize more of the solar power created by your solar panels. A long cycle life will offer the most affordable expense per recharge cycle (Tip: Search for a warranty that matches the mentioned cycle life. For instance, Melasta Lithium offers a service warranty on all batteries).
Lithium Iron Phosphate batteries supply the greatest Round Trip Efficiency (RTE) for solar/ solar grid energy conversion. That implies that 96 % of the energy saved in a Melasta Lithium battery is recuperated in a complete discharge cycle, making it one of the greatest performance batteries in the world. Additionally, unlike lead-acid batteries, the voltage curve for a Melasta Lithium iron phosphate battery is flat.
Here are some information points on various battery chemistries and the differences of RTE.
Vanadium Redox Flow = 69 %
Nickel Batteries = 74 %
Lead Acid = 76 %
Lithium Ion NMC = 82 %
Lithium Iron Phosphate = 88 %
Another advantage to the consumer is the far higher round trip efficiency of the LiFePO4 cell, which is generally better than 96 %. A "round trip" is a complete discharge and charge cycle.
For how much time will a battery hold a charge?
A Melasta Lithium Iron Phosphate (LiFePO4) battery has a normal self-discharge rate of 5 % per month. In other words, it takes 6 months for a LiFePO4 battery to self-discharge to the very same level a standard battery reaches in thirty days.
Melasta Lithium Iron Phosphate batteries supply the biggest lifetime worth for solar energy storage. Lead-acid batteries have the most affordable upfront financial investment, however, with brief life expectancy, you will require to change a lead-acid battery 4 to 5 times over the life-span of one Melasta Lithium battery. The performance difference is as follows:
ü Melasta Lithium battery has two times the usable power per charge. Because the voltage curve does not drop significantly like a lead-acid battery you have the ability to gain access to 96 % of the energy that your panels produce.
ü Melasta Lithium battery lasts 2,000 to 5,000 recharge cycles vs. 400 to 500 for a lead-acid battery.
ü Melasta Lithium battery is half the weight. This implies that you can have a battery bank in your house without the concern of it breaking or putting a dent on your flooring.
ü Melasta Lithium batteries are supported by the finest warranty. That means you can enjoy their lifespan and performance.
