Product Comparison: Renogy Vs. Goal Zero Lithium Solar Batteries
While most home batteries use lithium-ion technology, smaller batteries use a wide variety of materials, and unlike whole-house battery backup, can be made portable. Deciding which battery type and brand will work best for your situation can make a huge difference.
One of the competitors in the emergency backup sphere is Renogy’s line-up of batteries. Comparing these products with the Goal Zero products we carry will help customers determine which will work best.
Battery Chemistry: Renogy and Goal Zero
Lithium-ion batteries have become the gold standard among the current solar battery options. However, not all lithium batteries are the same. Lithium-ion batteries use a variety of different materials as the cathode, the electrode that absorbs electrons. Each one has different strengths and weaknesses.
While both Goal Zero and Renogy carry lithium-ion batteries, they use different types. Goal Zero uses lithium-manganese-cobalt-oxide (NMC) batteries. Renogy, however, has lithium iron phosphate batteries.
Goal Zero Lithium-ion NMC Batteries
Goal Zero Yeti 3,000 is a 3 kWh NMC battery. The combination of nickel and manganese fills in the gaps where the other lacks.
Nickel has high specific energy but low stability. Manganese has low specific energy and high stability.
Electric vehicles often use this lithium battery type. It has moderate specific power, safety, performance, life span and cost. It excels in specific energy, the energy to mass ratio, meaning these batteries typically weigh less than other battery types with comparable specs.
Renogy Lithium Iron Batteries
Renogy carries AGM, Hybrid Gel, and lithium-iron-phosphate deep-cycle batteries. Among these battery types, the lithium-iron-phosphate batteries last the longest, weigh the least, and require minimal maintenance, making them the best option among the Renogy batteries.
While this battery has high specific power and safety and a long lifespan, it also has moderate specific energy and a high self-discharge. Meaning this battery is heavier and it will lose its charge if it isn’t used.
Comparing Battery Capacity and Power Ratings
To better compare these batteries let’s look specifically at the capacity and power rating of each battery. These battery specs show how much power the battery can store and at what rate consumers can withdraw it.
Goal Zero Yeti 3000 Capacity and Power Ratings
The Goal Zero Yeti 3000 can store up to 3032Wh, equivalent to 3 kWh. It has a power rating of 1500 watts of continuous power.
Renogy Lithium-iron Battery Specs
The Renogy Lithium-iron-phosphate batteries have a capacity of 1200 watts or 1.2 Kwh. It can handle a continual draw of 600 watts.
Which Brand Carries the Better Battery?
Both batteries can connect to monitoring apps for remote battery monitoring and control. However, the Renogy lithium battery doesn’t have the ease of access that the multiple ports on the goal zero battery provide.
The Renogy battery comes rated for 4,000 cycles to 80 percent, while the Yeti 3000 is rated for 500 cycles to 80 percent. This could mean that the Renogy battery will last longer.
Goal Zero’s Yeti 3000 is hands down a beefier battery, even the Yeti 1500, the smallest battery in our product suite, will outperform Renogy’s lithium battery. The Yeti also has features that make it more user-friendly and portable. However, if you don’t want to switch out your battery as often and you don’t care about easily accessing the stored power, you may want to consider Renogy’s Lithium iron option.
