A grid connection can make sense if the transformer is close by.
When the distance increases, costs rise quickly.
Here we look at when it makes sense to have a grid – and when it makes more sense to be self-sufficient.<\/p>\n

With modern technology, everyday conveniences are also possible with an off-grid solution.
We find out which appliances can be used – and how to size them correctly.<\/p>\n<\/ul>\n
\n
Lithium or lead? How much capacity do you need?
We will go through battery selection, winter use and sizing based on practical experience.<\/p>\n<\/ul>\n
\n
Does a small windmill work in practice? And do you need an aggregate?
In this section, we look at energy production in different seasons.<\/p>\n<\/ul>\n
\n
What about domestic hot water, underfloor heating or an air-source heat pump?
In this section, we will go through the different types of heating and their suitability for off-grid solutions.<\/p>\n<\/ul>\n
\n
A well-designed system is safe and long-lasting.
Here we go through the most common pitfalls and how to avoid them.<\/p>\n<\/ul>\n
