The rising demand for electricity, driven by homes, businesses, AI, and vehicle electrification, makes efficient energy conversion critical. However, renewable energy sources, such as solar cells and batteries, generate low-voltage DC outputs (often less than 4V), while most applications require stable high-voltage AC (240V) or DC (12V–800V). Traditional power conversion techniques rely on multi-stage architectures and serialized energy sources, leading to inefficiencies, compounding losses, cascading failures, and increased system complexity.
Unlike traditional multi-stage systems, Daanaa’s PTU enables parallel connections for greater resilience while minimizing losses. Its real-time programmability adapts to changing conditions like sunlight and environmental conditions, battery state of charge (SOC), battery state of health (SOH), ensuring stable, optimized power transfer. By integrating multiple power functions into a compact, single-step module, Daanaa improves efficiency, simplifies system design and reduces engineering, operational, and maintenance costs.
Key Benefits
"We’re receiving growing interest from unconventional solar and energy storage applications struggling with efficiency," said Udi Daon, Daanaa’s CEO. "We’re offering a hands-on experience with our development system for Building-Integrated Photovoltaics (BIPV), Vehicle-Integrated Photovoltaics (VIPV), Energy Storage Systems (ESS) and more."
PTU Development System Available for Evaluation
Customers can evaluate the PTU’s capabilities using Daanaa’s development system, which connects to photovoltaic modules and batteries to demonstrate the technology’s potential in solar and energy storage applications.
BIPV and VIPV face challenges in optimizing solar energy generation due to irregular surfaces, dynamic shading, and complex power electronics. The PTU’s short-cell substring approach adapts to irregular surfaces, while per-substring DC optimization and ultra-fast MPPT maximize energy harvest even in dynamic shade conditions. Real-time configuration enables dynamic control of the output to a load.
The PTU also enhances battery performance. In electrified vehicles, it increases range by 10%, boosts motor power by over 40% and reduces charge time by over 50% without modifying battery cell count.
The development system includes an enclosed module featuring input and output connectors for easy integration with sources, loads, and measurement devices. It supports low-voltage DC input of 3V–6.7V and outputs either 380V-800V DC or 240VAC based on configurable settings.

WASHINGTON (AP) — President Donald Trump's 2026 budget plan would slash non-defense domestic spending by $163 billion while increasing expenditures on national security, according to White House statements Friday.
The plan shows a desire to crack down on diversity programs and initiatives to address climate change. But it doesn't include details about what Trump wants on income taxes, tariffs, entitlement programs or the budget deficit — a sign of the challenge confronting the president when he's promising to cut taxes and repay the federal debt without doing major damage to economic growth.
Budgets do not become law but serve as a touchstone for the upcoming fiscal year debates. Often considered a statement of values, this first budget since Trump's return to the White House carries the added weight of defining the Republican president's second-term pursuits, alongside his party in Congress.
House Speaker Mike Johnson, R-La., said the plan showed fiscal discipline given the problems of persistently high budget deficits. The budget released on Friday did not, in fact, include a forecast on government borrowing.
“President Trump’s plan ensures every federal taxpayer dollar spent is used to serve the American people, not a bloated bureaucracy or partisan pet projects,” Johnson said.
Sen. Patty Murray, D-Wash., said the cuts could ultimately be more extreme than what the administration has proposed, noting that the budget doesn't provide funding levels for programs such as Head Start.
“President Trump has made his priorities clear as day: he wants to outright defund programs that help working Americans while he shovels massive tax breaks at billionaires like himself and raises taxes on middle-class Americans with his reckless tariffs," Murray said.
The budget seeks to cut discretionary spending by a total of 7.6% next year, but includes a 13% increase in national security spending.
The State Department and international programs would lose 84% of their money and receive $9.6 billion, a cut that reflects the existing efforts by adviser Elon Musk’s Department of Government Efficiency.
The Housing and Urban Development Department would get a $33.6 billion cut, while the Health and Human Service Department would receive $33.3 trillion less and the Education Department's spending would be reduced by $12 billion.
The Defense Department would get an additional $113.3 billion and Homeland Security would receive $42.3 billion more.
The IRS and FBI would lose money, while the Low Income Home Energy Assistance Program would be ended. There would be $980 million less for college students in work-study programs, as well as similarly sized cuts for adult education and instruction for learning English.
The Centers for Disease Control and Prevention would lose nearly $3.6 billion under the plan, while the National Institutes of Health would face a steep cut of almost $18 billion. The budget would eliminate more than $15 billion for infrastructure-related programs tied to climate change and $1.3 billion from the National Oceanic and Atmospheric Administration.
The White House budget plan arrives as Trump has unilaterally imposed what could hundreds of billions of dollars in tax increases in the form of tariffs, setting off a trade war that has consumers, CEOs and foreign leaders worried about a possible economic downturn.
The White House's Office of Management and Budget, headed by Russell Vought, a chief architect of Project 2025, provided contours of a so-called skinny version of topline numbers only regarding discretionary spending. Administration officials said a fuller budget will come soon with plans to address the drivers of the annual deficit.
The nation's estimated $7 trillion-plus federal budget has been growing steadily, with annual deficits fast approaching $2 trillion and the annual interest payments on the debt almost $1 trillion. That's thanks mostly to the spike in emergency COVID-19 pandemic spending, changes in the tax code that reduced revenues and the climbing costs of Medicare, Medicaid and other programs, largely to cover the nation's health needs as people age. The nation's debt load, at $36 trillion, is ballooning.
Democrats are prepared to assail Trump's budget as further evidence that the Republican administration is intent on gutting government programs that Americans depend on.
Congress is already deep into the slog of drafting of Trump's big bill of tax breaks, spending cuts and bolstered funds for the administration's mass deportation effort — a package that, unlike the budget plan, would carry the force of law.
But deep differences remain among the Republicans, who are trying to pass that big bill over the objections of Democrats.
"We are awaiting some final calculations on a few of the tax components, and we expect to be able to complete that work on a very aggressive schedule,” Johnson said.
It's Congress, under its constitutional powers, that decides the spending plans, approves the bills that authorize federal programs and funds them through the appropriations process. Often, that system breaks down, forcing lawmakers to pass stopgap spending bills to keep the government funded and avoid federal shutdowns.
Vought is also expected on Capitol Hill in the weeks ahead as the Trump administration presses its case to Congress for funds.
Among the more skilled conservative budget hands in Washington, Vought has charted a career toward this moment. He served during the first Trump administration in the same role and, for Project 2025, wrote an extensive chapter about the remaking of the federal government.
Vought has separately been preparing a $9 billion package that would gut current 2025 funding for the U.S. Agency for International Development and the Corporation for Public Broadcasting, which involves the Public Broadcasting Service and National Public Radio. Trump signed an executive order late Thursday that instructs the Corporation for Public Broadcasting and federal agencies to cease funding for PBS and NPR.
Vought has said that package of so-called budget rescissions would be a first of potentially more, as the Trump administration tests the appetite in Congress for lawmakers to go on record and vote to roll back the money.
