We recommend installing the device in a partially covered location with good ventilation, protected from direct sunlight and rain. Suitable locations include balconies, garages, or storage rooms.
Installation guidelines:
1. Environmental protection: The device has an IP65 protection rating and is therefore suitable for semi-enclosed outdoor areas.
2. Ventilation distance: Maintain a minimum distance of 2 cm between the back of the device and the wall.
3. Stability: Place the device on a level, stable surface (incline no more than 5°). A stone slab or a stable platform is recommended.
4. Network coverage: For optimal Wi-Fi connection, install the device within a 15-meter radius of your router.
5. To avoid: Do not install the device in locations exposed to direct sunlight, rain, or near flammable materials.

1. Rigid solar panels: Very versatile. They can be installed in gardens or on roofs using ground mounts, or on balcony railings without drilling using clamps or hooks.
2. Lightweight rigid solar panels: Flexible design. They are suitable for installation on walls, on the ground, or on small balconies with optional mounting brackets. For optimal compatibility, we recommend Jackery's special brackets for this panel type.
3. Flexible solar panels: Ideal for small or curved balconies. They can be easily attached with straps, without any drilling. Don't attach them too tightly so that the material can expand and contract with temperature changes.

Panel orientation directly impacts power generation efficiency. The optimal orientation depends on the number of modules and your energy goals:
Module 1: Align it precisely to the south to capture the strongest sunlight at midday.
2 modules: Use an east-west combination. The east-facing module generates electricity in the morning, while the west-facing module continues to operate until the evening, thus extending daily production.
3+ modules: A combination of south, east and west orientation ensures a more balanced and longer electricity generation profile from morning to evening.
Note: These are general recommendations for Europe. For precise optimization for your location, we recommend using a professional solar design tool: https://pvgis.com/en

German regulations for small plants focus on "performance limits" to distinguish between simplified and formal approval procedures.
Important limit values ​​for a “small exempt installation”:
1. The total power output of the PV modules must not exceed 2 kW.
2. The output power of the inverter must not exceed 800 W.
If your system meets both conditions, it qualifies for a fast, simplified installation procedure and usually does not require a complex grid connection application.

If any of the limit values ​​are exceeded, a formal approval procedure is mandatory:
1. Submit a formal application: Contact your local network operator to submit a complete technical network connection application.
2. Hire a certified electrician: The installation and commissioning must be carried out by an approved electrician in accordance with German safety standards (e.g. VDE-AR-N 4105).
3. Prepare for system certification: The network operator may request certified device documentation and conduct a preliminary check.
4. Signing a grid connection agreement: After approval, a formal operating agreement must be signed with the grid operator.

The system supports four modes:
1. Self-consumption: Maximizes the use of your solar energy. Requires a smart meter.
2. Tariff mode: Saves money by taking advantage of price differences between peak and off-peak times. No smart meter required.
3. User-defined mode: Set your own charging/discharging schedules. No smart meter required.
3. AI Smart Mode: The system learns and optimizes itself automatically. Requires a smart meter.

It is used to power household appliances.
By installing a smart meter or energy monitor, you can activate the zero-feed-in function. This maximizes self-consumption by minimizing the amount of electricity fed into the grid.

Yes. The device features intelligent temperature control and operates at temperatures from -20 °C to 55 °C.
To ensure stable operation in winter, the system automatically activates the battery heater when the temperature drops below 0 °C and the device is connected to the mains power supply.

To achieve near-zero feed-in from the grid, you need a smart Jackery electricity meter (e.g., 3P) or a compatible energy monitor. This measures your household's total electricity consumption and grid exchange in real time.
1. If solar power generation exceeds your household's consumption, the system will automatically charge to absorb the surplus.
2. If solar power generation is less than consumption, the system discharges to close the gap.
This precise control aims for a net power exchange with the grid of almost zero.

The system forecasts your household electricity demand by analyzing the time-of-use tariffs you enter and historical data on your solar power production and consumption patterns. Using intelligent algorithms, it then automatically calculates and executes the optimal charging/discharging strategy – including scheduling, power levels, and grid mode switching. The system continuously learns and optimizes itself over time without requiring any manual input.

Yes. The Jackery SolarVault 3 series features a fast EPS (Emergency Power Supply) transfer function. In the event of a power outage, the system automatically switches from grid-connected to off-grid mode within 20 milliseconds, providing reliable emergency power for your critical equipment.

The device itself is a single-phase 230V system and cannot be connected to or output from a three-phase 380V power supply.

No, it cannot directly supply the other phases. The balcony system only supplies the single-phase circuit to which it is connected. However, by installing a three-phase smart meter (or an energy monitor configured for aggregated metering), any excess energy you generate can be fed back into the grid. This surplus can offset your consumption on the other two phases, thus reducing your overall electricity bill.
