Area of Use

Backup / Emergency Power Supply, EPS

Use your battery storage as backup power when you have had a power outage in the mains.

In the event of a longer crisis, for example after a storm such as storm Alfrida or Gunnel, you are with the solution that Orrevad Solar markets sure that you will have access to electricity as long as the power outage lasts, whether it is 1 hour or 1 month. This is because the battery is recharged by the solar cells during ongoing power outages in the mains.

Read more about our reserve power solutions.

A critical function with reserve power from battery storage is that the battery storage must be able to be charged by solar cells during an ongoing power outage in the electricity grid. In this way, you are guaranteed electricity in the property regardless of whether the power outage lasts for 1 day, 1 month or 1 year, given of course that the sun shines on the solar cells so that electricity is generated to charge the batteries.

The majority of battery storage systems for solar cells on the market are unable to be reserve power and / or to charge the battery during an ongoing power outage.

Orrevad Solar only delivers backup power solutions that can be charged by solar during ongoing power outages.

Peak-Shaving

Reduce your power charges with a battery pack.

Customers with power subscriptions with their electricity network company have the opportunity to reduce their power charges by limiting their power output from the network during the hours when they have the highest consumption. For each reduced kW peak power each month, you save in reduced fees to the electricity network company.

Time-of-Use / Arbitrage

Reduce your electricity costs with a battery store.

Charge the battery at night when electricity prices are low, discharge the battery in the morning when electricity prices are high. Charge the battery with free solar during the day, discharge the battery in the evening when electricity prices are high again.

Phase Balancing and lowered main fuse size

Do you have problems with the fuse blowing? Secure or prevent a breach of your main fuse and save money on your electricity subscription.

There are 2 solutions to enable a hedging or prevention of hedging of properties’ main hedging, through phase balancing and discharging of batteries.

A phase balancing function means balancing the load between phases L1, L2, L3. In this way, there will be the same load on all 3 phases even though you consume different amounts on the different phases within the property.

A discharge of battery function is implemented by controlling the batteries, for example to recharge the load on a phase> the size of the main fuse or to discharge with x kW when you normally have your power peak, e.g. between 11-14 every day.

More area of uses - Frequency control, Voltage support and more.

Large battery stores can be used for more functions in the electricity grid, such as frequency control, electricity quality improvement, capacity stabilization, voltage support, enabling predictable load schedules, etc.

In addition, the installation of batteries in the mains can make it possible to postpone mains reinforcements.

Most often, it is electricity network companies and various players in the electricity market that invest in large battery stocks.

Load regulation against electricity price is an additional function which means that the battery stock is charged and discharged depending on current electricity prices on the Nord Pool electricity exchange. The development of control of smaller battery stocks towards price levels on power exchanges such as Nord Pool has today not come far enough for this function to be commercialized.

Orrevad Solar only delivers turnkey contracts for smaller battery warehouses for residential and corporate properties. Smaller battery stores are not able to deliver the functions mentioned here.

Technology

Battery technology for properties is in a technological leap. There are many different solutions on the market, but they usually have narrow areas of use. Not all wishes are certain that it is possible to combine in one and the same system.

Battery storage can be installed both with or without a photovoltaic system connected to the battery storage system.
Battery storage can be based on either a DC-connected or AC-connected solution.

Does the battery storage system only need to work with a faultless network for power generation or energy transfer?

Does the battery storage system only need to have backup power without the requirement to be able to charge during an ongoing power outage?

Does the battery storage system need to have reserve power with requirements to be able to charge and recharge repeatedly during an ongoing power outage?

The choice of complete solution is based on your primary purposes with the battery storage system.
