TOM: My name’s Tom and I’m from Sol-ark and we’re the manufacturer of the Sol-ark 12k and 8k Hybrid inverters and–so our inverters are some of the most efficient in the world.

We really care about a lot of feature set, we want a rich feature set that will last, do a lot of things for our customers. AC couple, DC couple, very powerful, not a small inverter and very user friendly and easy to install. So, it’ll work with generators, it’ll do load shedding, it’ll do 120, 240, 208; soon 3 phase, peak shaving, time of use, you name it, we work with all kinds of batteries and the thing is we just keep trying to innovate because we want a really good product for our customers and for you guys.

ERIC: Tell me a little bit about your product compared to what we see out there like Tesla.

TOM: Ok, so, Imma give you a chart that basically, there’s a chart that compares a lot of different solutions out there. Tesla and–Tesla’s a good product out there, it’s decent. There’s just a few things not so great about it, is when you lose power it glitches all of your electronics. We’re a UPS grade Hybrid inverter, so when you lose power we glitch– we don’t glitch the electronics. We have a–

ERIC: So, my computer’s not going to go off?

TOM: No your computer’s–you might see the lights flicker a little bit, but your computer’s will stay on, you’re not gonna have to reset the time on all the different clocks, your DVR, that’s the key thing. I’m not gonna lose internet or my DVR, that’s the two key things. The other thing is we’re much more efficient and we work with generators. So, there’s less solar you have to install with about 5% less solar that you have to install with our system verses a tesla power wall, and people don’t realize, you know– Tesla that’s about 5 kW of an inverter per wall, so you need two of those Tesla Power Walls to equal one of our 12 kW systems and we still have more peak power to run those big appliances. So, that’s–those are some key things.

ERIC: Start an air conditioner or something big like that.

TOM: Yeah, start–maybe not a huge massive 5 ton

ERIC: Well pump? Well pump?

TOM: Oh, well pump, maybe some 2 or 3 ton air conditioners, those kind of things, no problem.

**TOM:** With our systems, you don’t void the warranty if you lose your internet connection.

Another advantage is that you can use higher-quality batteries. Those batteries may last 16 years instead of around 10 years. That can make a big difference over the life of the system.

**ERIC:** And you can use safer battery technologies.

**TOM:** Exactly. You can use safer technologies and batteries that may provide roughly twice as many charge cycles.

**ERIC:** So the cost of ownership can be lower over time?

**TOM:** That’s correct.

When we compare our system with two Tesla Powerwalls, the upfront pricing can look similar. Tesla prices the Powerwall competitively, but installation costs can add considerably to the total price.

Our system offers similar capabilities, but there are some important differences. For example, Tesla Powerwall does not offer the same UPS and generator-integration capabilities.

There are also efficiency differences to consider. Our system loses about 7% of the energy going into and out of the batteries. In our comparison, Tesla loses about 13%. That additional loss may require a larger solar array to produce the same usable amount of energy.

Battery life also affects the long-term cost.

If the batteries need to be replaced after about 10 years, you have another major expense. With our system, you can keep the inverter and replace the batteries separately when they eventually reach the end of their useful life.

When we include those replacement costs in the comparison, two Tesla Powerwalls would cost roughly $29,000 over a 16-year period, excluding installation and solar panels. A comparable system using our approach would be closer to $20,000.

So something that looks less expensive when you first see the price online may be very different when you compare lifespan and total cost of ownership.

**ERIC:** I think a lot of people don’t look closely enough at the long-term cost.

**TOM:** Right.

**ERIC:** They focus on what the system costs today.

**TOM:** Exactly. People often look only at the sticker price. They may not consider installation costs, replacement costs, and the other expenses that come later.

**ERIC:** And when federal incentives and rebates can help with the cost of a better system, it makes sense to look beyond the cheapest option.

**TOM:** Exactly. That’s also why I like lithium iron phosphate batteries. They can have a long cycle life, offer strong thermal stability, and work well for time-of-use applications like those in California.

**ERIC:** Absolutely.
