Under 20 kVA

Diesel Generators under 20 kVA

Generators under 20 kVA suit a specific set of applications. The output is enough to run essential circuits in a modest home, power a small off-grid cabin, or provide battery charging in a solar setup where the generator’s job is topping up storage rather than carrying the full household load.

For example, the DEUTZ DPS 13DF sits in this bracket. Paired with a battery bank and solar array, it works well for a small off-grid home running lighting, a fridge, a water pump, and a few small appliances. It’s also a practical choice for remote monitoring stations, small sheds, and caretaker quarters.

If your loads include air conditioning or heavy workshop equipment running at the same time as everything else, you’ll want to look at the 21–50 kVA range. Not sure? Our team can work through your energy requirements with you before you commit.

FAQs

Can a generator under 20 kVA run a whole house?

For a small to medium off-grid home where solar and battery carry the primary load, yes. The generator handles backup and charging rather than powering everything directly. Larger homes with air conditioning, electric hot water, and workshop loads will likely need a bigger unit.

Is a 13 kVA generator enough for off-grid backup?

That depends on how much energy you need, and how you plan to use your diesel genset. When the generator’s role is recharging batteries rather than powering the house directly, 13 kVA can be plenty, provided the battery bank and inverter are sized to match.
