Get the most out of your solar panels with the Battery vision home battery

To calculate the return, it is first determined how much you can earn in a year with a home battery if it is used for energy trading. This amount is determined based on dynamic energy prices from the past.

Next, the amount earned in the first year, divided by the total investment amount, and then multiplied by 100, to arrive at a percentage. Note! Past results are no guarantee for the future

In this “use case,” the premise is that the battery will ensure that you have access to the cheapest power all year round. The very cheapest power, is the power provided by your solar panels. Then the cheapest power, is the power you take off the grid, during the hour when your dynamic energy contract offers the lowest power rate.

The battery composition is chosen so that on an average day, surplus solar power is stored in the home battery for later use during the day and, in addition, the battery is filled with power from the grid, during the hour with the lowest price.

The total battery capacity covers your average daily energy needs, minus the power you consume directly from your solar panels. Does the battery capacity turn out to be too small in practice? It is always possible to add extra Battery packs afterwards.

Every home has a 1-phase or 3-phase connection to the electrical grid. This means that power enters your home through 1 power line or over 3 power lines. A 1-phase home battery can charge and discharge power over 1 power line and a 3-phase home battery does so over 3 power lines.

A 3-phase home battery can be chosen in a higher capacity because the electricity is distributed over 3 power lines. As a result, 3-phase home batteries can typically charge from and discharge to the grid faster. This can have great advantages when combined with a dynamic energy contract.

You can connect a 1-phase home battery to either a 1-phase or 3-phase main connection. A 3-phase home battery can only be connected to a 3-phase main connection. It can therefore be interesting to have your main connection adapted from a 1-phase to a 3-phase main connection for a limited amount of money. You can contact your grid operator for this.

The SOLARWATT Battery vision can also continue to supply power in the event of a power failure. The SOLARWATT Inverter vision has a separate backup output for this purpose, which can continue to supply power to all devices connected to it.
As a result, the refrigerator can stay on, your home can stay warm and your Internet connection can stay on. Which is nice with a power grid that is expected to become more unstable in the coming years, resulting in more power outages.

The SOLARWATT Battery vision is one of the safest home batteries available. During the development of the Battery vision, careful consideration was given to safety in all areas:

• The chosen cell technology LiFePO4 is the safest type of lithium ion battery. This cell technology has better thermal and structural stability. It can withstand very high temperatures without decomposing, it is not prone to “thermal runaway” and remains cool at room temperature. Battery cells also remain stable under short-circuit or hard impact.
• Battery management measures real-time temperature, voltage and current of the battery cells. If values become too high, the system automatically shuts down.
• The home battery has a robust aluminum casing and an insulation layer is provided between the casing and the cells. This prevents any incident from spreading fire and will prevent explosion.
• The enclosure is IP65 rated, which means it provides perfect protection against the penetration of dust, salt and water jets.
• Data security is well established. The same security standard is used as in the banking world and all data is stored on servers in Europe.
• The SOLARWATT Battery vision is subjected to much more stringent security testing than required by law for ultimate security.
