100 % clean energy

Our power stations are equipped with solar panels, and come with the option of mounting a wind turbine. Solar and wind are free energy sources that compliment each other perfectly when it comes to their up and down times.

Repurposed EV batteries

Using repurposed EV batteries, our power stations are equipped with storage options from 7 to 42 kWh, depending on your needs.We provide a 5 year warranty on batteries, but their lifespan is estimated to be up to 15+ years, around 4000 - 5000 life cycles.

Delivery

We deliver anywhere - a promise we must live up to, as our power stations are perfectly suited for off-grid use. At the moment we offer free delivery for a limited period (Save NOK 10,000). Delivery time is estimated at 3 weeks.

Zero risk for fatal fires

One of our main selling points is the value of putting a power station like ours on the ground outside the house/cottage, compared to mounting solar panels on the roof and installing equipment inside your home. Which comes with the possibility of fire and water damage with fatal and expensive consequences. This traditional setup also causes noise.

Get in touch!

If you have questions or are interested and would like a free inspection of your plot, contact us. We respond quickly. During an inspection, we will look together at the area of ​​your plot where it is most suitable to place a power station. Here we go through the size of the area, slope, solar conditions and the surface. See you!

Frequently Asked Questions

Yes, we do. Get in touch and see what possibilities we have. Where it is particularly difficult to reach with a crane, a helicopter may have to be used.

Building a Sowin unit on your own property is exempt from the application obligation according to the Planning and Building Act, provided that your unit is placed more than 1 meter from the neighboring boundary, your property is not unregulated or located in an LNFR area or in the beach zone, and the unit itself is not placed in conflict with:         

Building limit that appears in the zoning plan        

The degree of utilization for your property

Area purpose or consideration zone in the zoning plan

NB: all municipalities can make their own rules, so it is important to note that the rules can vary between different municipalities. It is therefore always a good idea to check with your local building authority to get the correct information about what is exempt from the application obligation in your municipality. You can find contact information on the municipality's website.

Ordered goods are sent by carrier and shipping is not included in the price. If SoWin advances the shipping, the shipping costs will be invoiced after. Delivery time depends on the charterer and place of delivery, but we operate on a general basis with a delivery time of between two to four weeks.

It is preferable for both parties. The customer should also provide an electrician if there is a need for the necessary connection inside the cabin or house.

SoWin Power uses recertified electric car batteries. These batteries go through a process after they are taken out of the electric car and are quickly ready for new use. This process allows the batteries to have a lifespan of up to 20 years, and approximately 4 to 5,000 life cycles. Each battery is 7 kWh. The maximum battery capacity in a power station today is 42 kWh.

The standard power station is equipped with a solar panel that has an output of 410 Wp (watt peak) and normally produces around 340 kWh per year. The cabinet can be expanded with more solar panels. On good sunny days, a panel can generate around 2 kWh of renewable energy. If you use the arms so that there are three panels, it will be about 6 kWh per day.

Today, it is possible to equip a power station with a battery capacity of 42 kWh.

The stands or the solar panels, if you want, do not have to be in the immediate vicinity. But it is recommended as close as possible. It is included (3 m length of the cables as standard. We have to investigate that, but it is also up to us.) there are relatively large currents in the cable, so long cables cause a lot of loss. One panel gives approx. 13 A in full sun, if the panels are connected in parallel, you can multiply this current by the number of panels. If the panels are connected in series, it is the voltage that can be multiplied by the number of panels. The panels are at 32 VDC.

It depends on whether the panel is in parallel or in series. In series, it will normally prevent the entire production in the series. This can be partly prevented with diodes (we have to investigate further if our panels have this built in) There are other ways to do it that we do not do and that is to replace an inverter with microinverters.
