Here is a rough take on budgeting for OffGrid.
30% Reserve for unforeseen issues
10% Live support, administrative and legal fees
When you live OffGrid it is important to have a certain financial reserves. If a vital systems breaks and you do not have a local backup installed or a workaround is impossible you might be in a position of having to source things quickly. If your water pump break in middle of summer whilst having farm animals, heating breaks in middle of harsh winter, power dies entirely, и т. д.. It is highly recommended to have backups in place for vital systems such as : water, electricity, heating. These backups don’t necessarily need be able to fully replace your default setup, but they should be reasonable sized to carry load for a while. Pricing of vital systems goes up by roughly 15-20% for having fallbacks installed. While it may look a big “price increase” you will need it sooner or later, 100% guaranteed some day something vital will break. Having systems setup from the start to take that into account can ease a lot of stress and basically removes the need for spending “emergency $/€” to workaround something until it gets properly replaced. бывший: having a generator is a legit “workaround” for your electric system, good to use when maintaining batteries, changing cables, installing new solar panels etc, but it is not a “backup” for when your main inverter dies. It is exponentially more expensive to run a full household 24/7 on a generator to maintain everything while you need to wait for your new inverter to arrive. The proper backup would be to have 2 inverters setup, use one as default and resort to using the 2nd if the default one fails. Casually order a new inverter. When it arrives, run your generator for 20 minutes whilst replacing the broken one.
