Fortress Power VS Rolls S6 GC2-HC Battery

Fortress Power VS Rolls S6 GC2-HC Battery - Alex with fortress power just wants to do a quick presentation on the fortress power versus rolls battery. So, as you can see on my screen, say I'll be comparing the fortress LFP 10 with 8 of the rolls batteries S6 GC2-HC. So, there are a few different things that I will bring up during this article on how a fortress lithium solution could be preferred against a roll's lead acid solution.

Fortress Power VS Rolls S6 GC2-HC Battery

1. The round trip efficiency

So, the first thing I will bring up is the round trip efficiency. So, you can see although the total energy and kilowatt-hours are relatively similar, the round trip efficiency of the lithium is much higher 98% in comparison to 70%. The round trip efficiency is essentially from the battery to the inverter, and then to the loads, you will get 90% of the 10 kilowatt-hours in the LFP solution, while only 70% in the lead-acid solution.

In that similar situation, the cycle life at 80% depth of discharge 6000 cycles versus 800 cycles. I mean that Feud cycle or battery once a day, you would last 12 to 15 years, while on the rolls battery if you cycled it once a day, maybe two years. So, if you look at the off-grid years, we can see at 16.4 years versus in 1.9 years with a lead-acid solution.

2. The energy throughput

Next, we would calculate the energy throughput in megawatt-hours. What does energy throughput? Energy throughput is the total amount of energy a battery can be expected to store, and deliver over its lifetime. So, with 1 LFP-10, you can expect 47 megawatt-hours of energy throughput, while in a lead-acid system maybe 5 megawatt-hours of energy throughput.

The lithium solution will then also cost less per kilowatt-hours than the lead-acid solution. So, although the upfront cost of a lithium solution might be a little bit higher. The longevity and cost per kilowatt-hour are going to be substantially less than, the roll system lithium is also much safer, and there is no maintenance.

With the roll system, they are not as safe as they will start to break down after a few years. Based on this awkward cycle number as well as some of the flooded lead-acid solutions need to. They need maintenance, once every few months to refill the water, etc.

3. Performance comparison

So next, I'm gonna go over a performance comparison of LFP versus lead-acid. So, what will kind of look at is like the current increases. The capacity will drop in the typical lead-acid situation with this green bar, right here this is lithium. So, as you increase your current, your capacity will say consistent, but as you can see, has your current goes up, and let acid your capacity drops.

What does this mean? It means that, if you're powering a load with a large current, your capacity of the lead-acid drops, thus meaning you're not gonna be able to power that electrical load with the lead-acid system that's in. Because you are losing capacity as you're powering more, so not only is your capacity you're gonna drop when your output increases, but lead-acid is gonna fire at least six times more space.

Quite possibly the most well-made battery on the market, the eFlex 5.4 kWh lithium battery from Fortress Power comes with built-in wifi for remote monitoring and troubleshooting to complement its 10-year warranty with the safe and premium prismatic Lithium-Iron-Phosphate cells.

And I'll have higher cable costs in a longer installation time. So, I have a space comparison. We have the Evo 18.5 and we have some AGM batteries. This lithium solution is a lot less small almost 1/3 the size and a third of the weight of the AGM's but has substantially more capacity 360 amp hours versus 250 amp-hours. In the AGM batteries, you're not able to use all 250 amp-hours. You'll only be able to use 6 kilowatt-hours in congruence to the 18.5 kilowatt-hours on the lithium solution.

Final Words

I hope that you guys all found this article very informative and helpful. And some of the key features of the lithium iron phosphate technology that fortress power uses include the superior safety of the lithium-ion phosphate chemistry the high throughput.

The 47 megawatt-hours of throughput that the battery can be expected to store in the liver, the long duration of the 12 to 15-year lifespan, and the low energy costs. The cost per kilowatt-hour for the system is definitely lower than the roll's battery.
