In the mountains of Jayuya, Puerto Rico, the road becomes narrow, the city noise fades, and the landscape turns quiet. Far from San Juan, surrounded by nature and mountain roads, Jayuya is a place of beauty — but also a place where access to essential services can be difficult.
For many residents, traveling to San Juan, Ponce, or other cities for medical care can take more than an hour. For patients who need ongoing treatment, that distance is not just inconvenient. It can become a barrier to care.
That is why the Ven-Rose Health House Foundation matters.
Ven-Rose is a nonprofit medical center in Jayuya operated by trained volunteer professionals. The Foundation provides essential services including oncology care, kidney treatment, mental health services, preventive counseling, and community outreach programs. For many local residents, Ven-Rose helps keep critical care close to home.
But healthcare depends on more than doctors, volunteers, and treatment rooms. It also depends on power.
In Puerto Rico, power outages are more than a temporary inconvenience. For a healthcare facility, even a short outage can interrupt treatment, affect medical equipment, disrupt refrigeration, and place additional stress on patients and staff.
The Ven-Rose Health House Foundation has experienced temporary power outages that can become especially serious when treatments are underway. Natural disasters such as hurricanes and earthquakes also create the risk of extended outages. The goal of the project was to help the Foundation implement a photovoltaic power system that could provide more reliable and resilient electricity for the site.
For a rural medical center in the mountains, backup power is not simply a technical upgrade. It is part of protecting care. It is part of keeping services available. It is part of helping a community feel safer, stronger, and more prepared.
This project began with a bigger purpose than energy alone. As part of its 25th anniversary, AZ Engineering chose to turn a company milestone into an opportunity to give back — supporting the Ven-Rose Health House Foundation with a donated microgrid project built around hope, resilience, and continuity of care.
Developed in collaboration with the student chapter of Engineers Without Borders at the University of Wisconsin–Madison, the project represents a fully donated system valued at $168,640, made possible through the combined efforts of companies, organizations, engineers, students, and volunteers committed to making a difference.
Through the Pytes Care initiative, Pytes contributed the energy storage foundation of the system: 80kWh of Pytes V16 battery capacity.
The result is not just a solar installation. It is a stronger energy lifeline for a medical center whose mission cannot pause when the grid goes down.

The UW–Madison Engineers Without Borders Puerto Rico team has worked with communities in Puerto Rico since 2018, supporting reliable and sustainable electricity through solar power. Their Puerto Rico project has included work in Mayagüez, Benitez, and Jayuya.
Now installed, this microgrid brings together solar generation, Pytes battery storage, Sol-Ark inverter technology, and generator backup to help Ven-Rose operate with greater resilience.
For Ven-Rose, choosing a battery system was never just about capacity. It was about trust. In Jayuya, power does not simply support convenience. It supports care. It keeps treatment rooms running, medical equipment ready, and the doors open for patients who may not have another nearby place to go. That is why the Pytes V16 was selected for this project.
In a medical facility, every layer of protection matters. The Pytes V16 is designed with enhanced safety features, including built-in aerosol fire suppression and ESS emergency shutdown capability. For Ven-Rose, that means more than technical protection. It means volunteers, doctors, patients, and families can feel more secure knowing the system behind the clinic was built with safety as a priority.
Jayuya's mountain environment, heavy rain, humidity, and Puerto Rico's tropical climate make durability essential. Energy equipment here has to face more than daily use. It has to stand up to the conditions of the place it serves. With an IP66-rated enclosure and C4-M anti-corrosion protection, the Pytes V16 is designed for demanding outdoor environments, helping the system remain dependable through Puerto Rico's challenging weather conditions.
This project is not a short-term solution. Ven-Rose is a long-term part of the Jayuya community, and the energy system supporting it needed to be built with the same long-term vision. With 8,000+ cycles and an expected lifespan of up to 20 years, the Pytes V16 helps provide dependable energy storage for years of care, treatment, and community service.
For a project where people's well-being is at the center, safety cannot be assumed. It has to be proven. The Pytes V16 is supported by key safety certifications and testing standards, including UL 1973, UL 9540, and UL 9540A testing. Built with Tier 1 Grade A LFP cells, it reflects the reliability Pytes brings to every project — especially those where energy means more than power. At Ven-Rose, the Pytes V16 is not just storing electricity. It is helping protect a place where people come for healing, support, and hope.
For many solar and storage projects, the value is measured in utility savings, payback periods, and energy independence. At Ven-Rose, the value goes deeper.
It is measured in the ability to keep care available. It is measured in the confidence that treatment can continue when the grid is unstable. It is measured in fewer interruptions for patients, volunteers, and the community. The system does not just power a building. It helps power a place of care.
The inauguration of this microgrid represents more than the completion of a technical project. It is the result of shared purpose, collaboration, and community commitment.
AZ Engineering transformed its 25th anniversary into an act of service. Engineers Without Borders brought student leadership, engineering dedication, and long-term project planning. Local partners and volunteers helped turn the vision into reality. Pytes contributed 80kWh of V16 energy storage through Pytes Care to help make the system resilient.
Together, these efforts created a fully donated microgrid for a foundation that serves families and patients who rely on care close to home. For Pytes, this is what Power a Better Life means.
It means energy storage should not only support homes and businesses. It should also support care. It should support communities. And it should help create stability in places where reliable power can directly impact people's lives.
In Jayuya, surrounded by mountains and silence, Ven-Rose stands as a place of hope. Patients come there for treatment, guidance, comfort, and support. Families come looking for care closer to home. Volunteers and medical professionals give their time to serve a community that depends on them.
Now, with the new microgrid in place, that mission has a stronger foundation. When the grid becomes uncertain, Ven-Rose has another layer of protection. When outages happen, care has a better chance to continue. And when a community needs resilience, energy storage becomes more than technology — it becomes part of the support system behind healing.
Pytes is honored to support this project through Pytes Care. Because better energy is not only about powering buildings. It is about powering hope, service, and a better life.
Pytes Care — Power a Better Life.
“Reliable power means more than keeping the lights on. For Ven-Rose, it helps keep care close to home for the people of Jayuya.”
