☀️🚗 ESY EV22 | More Than Charging. Powering a Connected Home.

At ESYsunhome, we believe energy should move beyond boundaries: connecting the power of the sun, your home and your electric vehicle.

With the ESY EV22, your EV becomes more than a means of transportation. Through bidirectional charging, it can also become part of your home energy ecosystem, supporting Vehicle-to-Home (V2H) applications.

Here's what makes EV22 a smarter addition to your home energy setup:

☀️ Solar & Grid Charging
Use energy from your rooftop solar or the grid to charge your EV, with the flexibility to make the most of off-peak electricity rates.

🔄 22 kW Bidirectional Power
Go beyond one-way charging. EV22 enables two-way energy flow between your vehicle and home, turning your EV into a potential backup power source.

🏡 Built for Outdoor Use
With an IP65-rated design, EV22 is suited to outdoor installation, with protection against dust and water jets.

⚡ True DC Coupling
Fewer energy conversion steps mean less energy loss along the way.

From the sun to your home, from your home to your vehicle.ESY is making energy more connected.

Good Energy, Within Reach.

ESYsunhome | Rooted Deep, So AI Truly Grows With Your Home

True growth has never been about surface noise.It is about sinking roots deep enough that value can accumulate steadily over time.
We have placed this power of growth into the hands of AI, turning it into a long-term smart energy partner for your home:

🌿 Negative Price Mode — Rooted deep, protecting household value
Don’t let sunshine become a liability. When electricity prices turn negative, pause all PV generation with one click — including third-party inverters — and prioritise grid purchases. Fully developed in-house, this ensures every kilowatt-hour captures the price difference and safeguards your home’s value.

☀Predict PV Power Output — More reliable foresight, so every ray of sunlight has reachable value
While the industry still relies on rough city-level forecasts, ESYsunhome’s AI already delivers predictions at 20 km² grid level. Greater accuracy creates more opportunities for energy arbitrage, making forecasts more trustworthy and decisions more confident.

📊 Automatic Tax & Fees Pre-Filling (50+ Grid Operators) — Precision down to every cent
Tired of entering taxes and fees manually? Select your grid operator from our built-in database covering 50+ operators, and the system automatically fills in the relevant taxes and fees with one click. We handle the complex compliance, leaving you pure convenience.

🏖 Vacation Mode — Even when you’re away, AI keeps growing for you
Activate with one click. Even when you’re away, the system continues earning.AI automatically reduces reservations for non-essential loads and adjusts forecasts, freeing up more electricity for energy market trading. This is ESYsunhome’s long-term commitment as your smart energy partner — keeping returns growing steadily in your absence.

Good Energy, Within Reach.

⚡ For C&I energy storage, a smarter strategy starts with understanding your power needs.

From production equipments to other heavy loads, businesses rely on a wide range of electrical equipment throughout the day. Managing these energy demands efficiently takes more than simply choosing a battery with the right capacity.

💡 Timing matters, too. With time-of-use tariffs, energy storage can help businesses make use of lower-tariff periods and manage consumption during higher-price periods, depending on local tariff structures and operating needs.

🔋 ESY's C&I Energy Storage Products offer solutions for different energy management needs:

• ES125-261 provides battery energy storage to support flexible energy management based on operational needs.

• ES130-261 combines an inverter and battery storage, supporting integration with solar PV, grid, and a diesel generator for flexible energy supply and backup loads.

Both systems offer a starting point for building an energy strategy around your actual load profile, operating hours, and backup requirements.

Because smarter energy management begins with understanding when, where, and how your business uses power.
