KW Solar CTO Ted Hawkes standing beside EP Cube 2.0 residential energy storage solution during setup
On a recent install in Friendswood (south of Houston), KW Solar walked through an EP Cube 2.0 setup. In this case study, you'll see what stood out most on site.
KW Solar has been a trusted partner, helping homeowners install EP Cube systems. In Friendswood, Ted Hawkes, KW Solar's Chief Technology Officer, shared what mattered most to this homeowner and why their team recommended EP Cube 2.0.
As Ted put it, "They liked the modularity of the system," and "being able to choose their battery capacity and have it scale very tightly." He also noted that "the price point is very competitive."
From there, the install became a practical test of two things: how smoothly the system goes in, and how it performs when the grid actually drops.
One of the clearest benefits of a modular home battery is flexibility. Instead of committing to one large, fixed size, you can choose a starting point that matches your household energy goals and budget, then expand later.
KW Solar repeatedly comes back to future upgrades. The EP Cube system is described as essentially plug-and-play for common add-ons later.
"If in the future the homeowner decides to add an EV charger, it's essentially a plug and play. If they decide to add a generator, that's a plug and play."
That matters because energy needs rarely stay static. A system that can scale later reduces the risk of buying the "wrong size" today and helps homeowners plan upgrades on their timeline.
And beyond function, Ted also notes the design: "The system looks sharp. Streamlined looking, clean lines, [and] no sharp corners." It fits well with a modern home aesthetic.
One of the most common questions homeowners ask is how long does it take to install a solar battery? The full timeline depends on permitting, electrical work, inspections, and site conditions. But what stood out in this install was the focus on reducing friction: both in hardware setup and in commissioning.
KW Solar noted EP Cube 2.0 is easier to install than the first generation, with simplified mounting and wiring.
"These things clip together like Legos", said Ted. And he emphasized that the assembly avoids extra work later: "There's no wiring after the fact."
"This should take about 45 minutes max. Once we've done a couple of them, and we've worked out the kinks. And kind of know what to look for and where."
Ted also calls out a smoother commissioning experience: "I would say it's 50 percent smoother than most production systems we've done out there."
He highlights the app experience as quick and interactive, with fast serial-number scanning and a guided workflow that doesn't require special training.
A strong expandable home battery backup plan isn't just about battery size. It's about using stored energy intentionally when the grid goes down.
KW Solar emphasizes EP Cube 2.0's "smart circuit" capability: instead of treating all loads equally, you can choose specific circuits on the backup bus and make them intelligent - so you can shed or deprioritize loads you don't want to spend battery power on.
This kind of control supports more practical grid outage backup, keeping essentials running longer.
KW Solar also highlights EP Cube's generator integration as a valuable extra layer of resilience. When solar isn't available, like at night or during severe weather, and the battery runs low, a generator can step in to recharge EP Cube and help extend your backup time.
To validate power outage backup readiness, KW Solar ran a simulated grid outage test solar battery backup scenario.
During the test:
For homeowners, that demonstration is the point: not just what the system claims on paper, but what it does when the grid actually drops.
From KW Solar's perspective, this install showed the value of a system that is modular, easier to install, simple to commission, and built for grid outage backup, with smart controls and generator support for real-life priorities.
