Power Inverter Output Waveform
The AC output waveform of the inverter is modified sine wave having
characteristics similar to the sine wave shape of utility power. This type
of waveform is suitable for most AC loads, including linear and switching
power supplies used in electronic equipment, motors, and transformers.
This waveform has an RMS (root mean square) voltage of 115 volts,
which is the same as standard household power. Most AC voltmeters
(both digital and analog) are sensitive to the average value of the
waveform rather than RMS. They are calibrated for RMS voltage under
the assumption that the wave form measured will be a pure sine wave.
These meters will not read the RMS voltage of a modified sine wave
correctly, reading about 20 to 30 volts low when measuring the output.
For accurate measurement of the
output voltage of the inverter, use a
true RMS reading voltmeter such as
a Fluke 179, Fluke 79 III series,
Beckman 4410 or Triplett 4200.
Power Source Requirements
The inverter is well suited for heavy loads such as well pumps, small
compressors, small wire feed welders and other loads requiring a high
inrush starting current, high amp starting load. Induction motors, as well
as some other loads, may require two to six times their rated wattage to
start up. A SUNRNR’s inverter has a peak watt power rating that may
allow such appliances and tools to be operated safely. The equipment
needing the highest starting wattage is pumps and compressors that
start under load. This equipment can be safely tested and if an
overload is detected, the inverter will simply shut down until the
overload situation is corrected and the inverter reset.
Appliance Power Consumption: Most electrical tools, appliances and
equipment have labels that show the device’s power consumption in
amps, watts, or both. If only amps are given, Watts may be calculated
by multiplying amps times volts AC (either ~115 or ~220).

DO NOT allow the SUNRNR to become inverted or fall
on its sides/ends - keep upright on its wheels, handles up.
DO NOT operate SUNRNR unless it is upright as above.
SUNRNR weighs more than 250 pounds - DO NOT roll
over toes, fingers, feet, pets, or anything that might be
damaged or injured and DO NOT lift alone.
To prevent cuts from sharp edges, use gloves when
lifting SUNRNR from the bottom.
NEVER CONNECT NEUTRAL OR LINE 1, HOT LINE,
AC OUTPUT TO GROUND, NEUTRAL MUST FLOAT!
DO NOT operate SUNRNR if unit is wet; allow to dry
thoroughly before operation.
Do NOT cover or operate unit in unventilated areas.
The SUNRNR AC outlets have ground fault protection.
Always use cords and appliances with grounded, 3 prong
plugs, for maximum ground fault safety.
Cigarette lighters can fit into the 12 VDC socket,
become extremely hot, cause serious burns, or start fires –
Never touch hot end to something that might burn.
Always disconnect ALL plugs from outlets or portals by
grasping plug only - Never unplug by pulling cords.
If you see or smell smoke, sparks or fire, turn off the
SUNRNR main switch.
DO NOT plug in battery chargers for cordless power
tools if the charger carries a Warning that dangerous
voltages are present at the battery terminals.
Dangerous voltages inside unit and solar panel junction
box – DO NOT open unit or junction box.
Avoid high winds while handling solar panel.
Not approved for use with medical equipment.
CAUTIONS
NO USER SERVICABLE COMPONENTS INSIDE.
OPENING UNIT WILL VOID WARRANTY.
Do not operate over 3500 Watts continuous.
Ensure devices to be operated do not exceed Wattage
limitations and are OFF before plugging into SUNRNR.
DO NOT operate SUNRNR if it is wet.
Keep in well-ventilated area when in use.
Do NOT use with small, Ni-* battery-operated
appliances that plug DIRECTLY into AC receptacle.
