TECHNICAL REPORT ON THE ENERGY PERFORMANCE OF VIVA SMART PRODUCTS
Introduction
The VIVA SMART system was created with the goal of offering maximum energy efficiency and operational autonomy, minimizing consumption while ensuring a constant energy supply even under suboptimal solar irradiation conditions.
Unlike traditional photovoltaic storage systems, VIVA SMART is designed as a CHARGE/DISCHARGE/STORE system, capable of dynamically managing incoming and outgoing energy, keeping essential functions active even during periods of limited energy availability.
The system uses high-efficiency components such as:
- MPPT charge controllers
- High-efficiency photovoltaic panels, including PERC type
- High-energy-density and long-life batteries
- Intelligent electronic management via proprietary BOARD
System Features
The VIVA SMART BOARD automatically manages energy flow, deciding which modules to activate based on energy availability.
Practical examples:
- Deactivation of wireless charging in case of low remaining energy
- Automatic dimming of LEDs to optimize consumption
- Energy-saving mode when critical battery thresholds are reached (30% and 10%)
Operation and Use Cases
1. Daytime Operation
Reference example: VIVA SMART BENCH art. 311301
- Photovoltaic panel: 60 W (PERC)
- Storage battery: 36 Ah
- Accumulated energy (estimate): 36 Ah × 12 V ≈ 432 Wh
With a fully charged battery (typically obtained in 6 hours of full sun), the system can recharge up to:
- 12 mid-to-high-end mobile devices (iPhone 13 / Samsung S22, average consumption 30–35 Wh per full cycle)
During full sun exposure, the current delivered by the panel (≈ 60 W) allows unlimited direct charging, while under partial irradiation (≈ 50%) it maintains the capacity to charge an additional 6 devices.
2. Nighttime Operation
In the absence of solar irradiation, the system operates using the energy stored in the battery:
- Full functionality until 30% of remaining capacity
- Maintenance of basic functions (control, monitoring) down to 10%, automatic shutdown threshold
3. Restart After Complete Discharge
Thanks to the CHARGE/DISCHARGE/STORE logic, the VIVA SMART system:
- Restarts after about 2 hours of irradiation, even partial
- Is immediately operational, unlike traditional systems that require hours/days to accumulate energy
4. Extended Absence of Sunlight
Even after several days of cloudy conditions, the system automatically reactivates as soon as it receives a minimum of 2 hours of sunlight, ensuring immediate restart and continuous service ("NO STOP").
