2. PRODUCT DESCRIPTION
Overview
The Little Genny or Little Genny Emergency Power Kit (“Little Genny EK”) is a portable rechargeable
generator that converts low voltage direct current (DC power) to 115-volt Pure Sine Wave alternating
current (AC power). The Little Genny stores electricity from any power source (e.g. grid, solar, wind, or
car) in its 12-Volt DC Lithium Ferro Phosphate (LFP) batteries, and uses that stored energy to power
lighting, electronics, and other devices when normal AC grid power in not available, such as in the cases
of power outages, emergencies, or field work. The Little Genny Emergency Power Kit includes additional
PV charging from a portable solar module.
The Little Genny Includes (portable PV solar module with Emergency Power Kit only):

Knowing Your Power Requirement
The loads connected to the Little Genny should have a combined power draw that does not exceed the
inverter’s 300-Watt continuous power rating / 700-Watt surge power rating. Prior to connecting an
appliance to the Little Genny, determine how much power your appliance requires to run (“continuous
load”) and to start up (“starting load” or “peak load”).
Power consumption is rated in Watts, or it can be calculated from Amperes (Amps). This information is
usually stamped or printed on most appliances and equipment. If this information is not indicated on the
appliance or equipment that you wish to connect to the Little Genny, check the appliance’s manual for its
power ratings.
Calculate power consumption (Watts) by multiplying the appliance’s AC Amperage rating by its AC
Voltage rating:
AC Amps x 120 Volts = AC Watts
This formula yields a close approximation of the continuous load of your appliance.
When a motorized appliance or a tool turns on, there is an initial surge of power to start. This surge of
power is referred to as the “starting load” or “peak load.” Once started, the tool or appliance requires less
power to operate (referred to as the “continuous load”).
Calculate the appliance’s starting load by multiplying the appliance’s continuous load draw by two:
AC WattsContinuous x 2 = AC WattsStarting
This formula yields a close approximation of the starting load of most appliances. To ensure that the Little
Genny is capable of powering the appliance at hand, check the appliance’s manual for its Starting Watts
rating.
Knowing Your Energy Requirement
The amount of energy consumed by loads connected to the Little Genny is equal to the loads’ power
draw multiplied by the loads’ runtime:
Power Draw (Watts) x Runtime (hours) = Energy Draw (Watt-hours)
The batteries included in the Little Genny have a rated capacity of 322 total Watt-hours DC / ~257.6 Watt-
hours AC (assuming an inverter efficiency of 80%). Connected loads consuming more energy than
~257.6 Watt-hours will result in low battery voltage and inverter shutdown. See Table 1 below for
expected runtimes for various loads.

*Runtime may vary depending on the Little Genny battery’s starting State of Charge, the type of
connected appliance (AC or DC), and the operating efficiency of the Little Genny’s inverter while the
loads are connected.
