Power Products Sigma 7000W

The Sigma is a powerful 7,000W surge power and 5,500W continuous power generator that will be more than enough to help you run a small house off grid without facing any problems whatsoever. The unit is one of the generators that create just 68 decibels of noise at its full operating capacity.

If you are looking for a fuel-efficient solution for your power needs, the Sigma presents a simple solution. The four gallon capacity of the generator allows the machine to run for eight hours straight at half capacity, which is more than decent for the amount of power output that the generator can produce.

Best Diesel Generators for Off Grid use Buyers Guide

Things to Consider When Buying Generators

When you are looking for the best diesel generator for off grid use, you should keep a few things in mind to help you make the right decision:

Generator Size

Generators are sold based on the watts they can produce. In order to determine what size you should get, you need to consider the power output you will require. You should also think about whether you need the generator as a primary source of power or if you need to supplement your alternative power supply with the product.

Run Time

If you are looking for a primary power source, you need something with a continuous run time. This factor isn’t important if you need it as a backup source. The greater the capacity of the fuel tank, the longer run time you can expect.

Final Thoughts

Diesel generators are much better than gasoline generators and LPG propane generators due to their greater fuel efficiency and lower maintenance requirements. They might generally be a little heavier and louder, but their benefits outweigh the advantages of generators that use other types of fuel.

Between the comprehensive reviews and considerations to make, we are confident that you have all the information you need to pick the best diesel generator for off grid use and get something within your budget from this list.
