So, we're going to make a quick video about if it's cheaper to do a DIY modular system or an all-in-one power system with a battery because I made a video yesterday and a lot of people were saying that the unit is too expensive. And it's absolutely false if you do the math. And this isn't trying to support that company or any company. But I want to show you guys the numbers so that you know that usually the all-in-one power systems are much cheaper. And I'm also not trying to support all-in-one systems because there are pros and cons to that versus a modular system. So let's do the numbers. So first let's make an imaginary system with the same power capabilities as the Titan solar generator. So first let's say we need a pure sine wave inverter. Let's get the cheapest Chinese one on Amazon. It's $350. Next we need two 40 amp MPPPTs that are capable of,000 watts for a nominal battery voltage of 24 volts. $400. And that's the cheap cheap one. That's a Tracer BN. All right. Next, let's get a DC/DC charger. Let's get the cheapest one on the market, the Reny. $188. And you have to wire up the ignition circuit. Um, copper wire, quality OCPD connectors, fuse box. And that cost is $280. And I don't care if you're making an expensive system or a cheap system, it is always that cost because copper wire is not cheap and nice OCPDs are not cheap. So, yeah, $280. Next, you need tools. $120. Just like $30 for this, $30 for that. I mean, this stuff adds up quick. This is a very cheap estimate. Next, we need a step down converter, an automotive cheap one, China, $35. Capacity monitor, the exact same one that they have from Reny, $100. Now, a 2 kWh battery with BMS. Let's say the average is around 79 cents per watt hour. But that's lithium iron phosphate. They did change charge cycle life and it's lighter on the Titan. I'm just trying to ballpark it here. Okay, that's going to be $1,583. If you build it with the cheapest quality components, it's going to be $3,056. It's already cheaper to buy an all-in-one system just with those. And that doesn't talk about the transfer switch or anything else or building it or the case. Now, let's take this estimate and use higher quality components like Victron and nice inverters. So, first pure sine wave inverter, $600. These can be upwards of $1,000 for a 3000 watt continuous. So, $600 is still cheap. Okay, I'm going to expect that you're getting a Victron on sale. Next, um 40 amp MPPPT, but by Victron, um $640 with the voltage limitation that the Titan has. $640 bucks. Next, $350 for a Sterling or a Red Arc or another battery isolator that is higher quality than the Reny with, you know, um, a voltage sensitive relay and so on. Um, copper wire, quality OCPD connectors, $280. Tools, $120. This could easily shoot up to $200 or $300. I spend hundreds of dollars myself on wire and tools. It's crazy. Next step down converter, just a cheap one, $35. Capacity monitor, $100. And now a 2 kWh battery. Let's say we get the Victron one or like a simplified. That's going to be around $2,200 for 2 kilowatt. We're going to spend $4,325 and the all-in-one power system by Titan is only $2,900 with that one 2 kWh battery pack and you can scale it. It is absolutely cheaper to buy an all-in-one system. This also applies to MPPP all-in-one systems that do not have the battery where it has an inverter, a charge controller, an automatic transfer switch, those are always cheaper as well compared to buying the parts yourself. And even though all-in-one power systems are objectively cheaper, there are downsides. Okay, I understand that there's downsides compared to a modular system. If you get the highest quality component like inverter and transfer switch and stuff like that, of course, you're going to have some really great stuff. You can swap out parts and each part has a warranty, but I just want to drive home the point that it is still cheaper to actually buy an all-in-one power system. And yesterday I had like a hundred comments saying it was expensive. I think people are not accustomed to building systems with lithium or with larger size components, especially with expensive solar charge controllers because those costs can go up very very quickly. And if you're trying to build a high quality stationary system that will last 10 or 20 years with a large battery bank, you're spending like, you know, $10 to $20,000. Even if you have a grid type battery backup system, those are not cheap. The LG or the Tesla Power Wall, that is not cheap at all. So, those comments really confuse me. I just want to know where you guys are getting your numbers from. If you guys disagree with something that I said in this video, please write it down below. If you do not agree with the math that I did, any of the estimates, please let me know. Also working on another video. This is a Jackaryi torn apart. And yeah, I can't wait to finish this one. But yeah, just a quick update video. Just had to share those numbers. All right, I'll talk to you guys soon. Thank you so much for watching. Bites. ...
