About
Humless
Humless, LLC gives you a seamless solution for
challenging power outages. Our technology is so
advanced that we have no real competitors. There
may be other generators available, but none can
offer you all of the following:
Safe:
No emissions – none. No dangerous risks unlike fossil
fuels and toxic lead-acid batteries (if you can’t throw
it away in your family’s garbage can, it’s not good for
your family).
Silent:
No more loud, continuous, sanity-challenging
generator noises.
Affordable:
The next competitor that compares in power,
1000 watts continuous, costs 3 times more.
Portable:
Easily carried by most, weighing in at 40 lbs. (18 kg.)
Renewable:
Powered and replenished by natural resources such
as the sun, wind and water, as well as mechanical
devices such as hand cranks.

Troubleshooting
Your Unit
1. The Charge Status Indicator won’t light up when I push
the green button.
• Make sure red key is inserted into the Main Power keyhole
and it is turned to the “ON” position.
• Battery is below cutoff voltage – charge battery.
2. The red light above Switch 1 on the 120V AC Outlet lights
up and there is no power from outlet.
• Battery is low. Check charge state and recharge battery.
• Load is too high. Turn down appliance or make sure
appliance power ratings are less than 1000W.
• Inverter overheating. Create space around vents and allow
inverter fan to cool the inverter.
3. The Charge Status Indicator lights give different readings
at different times without charging or using any stored
power.
• Charge Status Indicator provides approximate charge
status only.
• Battery pack voltage will settle after charging.
4. DC Input charging light will not light up, even though my
charging source is plugged in.
• Make sure red key is inserted into the Main Power keyhole
and it is turned to the “ON” position.
• Input polarity is reversed. Reverse input polarity.
• Charging source voltage is less than your battery voltage –
try a different charging source.
5. 12V DC Outlet won’t work.
• Make sure red key is inserted into the Main Power Switch
and it is turned to the “ON” position.
• Battery is below cutoff voltage – charge battery.
