MODIFIED SINE WAVE is a sales term used for a modified square wave
type of AC power which is not quite the same as power company electricity.
Modified wave inverters are lowest cost, slightly more efficient, and almost all
appliances work fine with them, though some may hum louder. But a few sewing
machine speed controls have difficulty on modified sine
wave. It can also damage photocopy machines, laser printers, and some cordless
tool rechargers. Recently we found the first TV that would not run on any
modified wave inverter. Battery chargers in some modified waveform inverters may
require the highest quality generator (about $3000 and up) to charge effectively,
or addition of a 10% voltage boost transformer.

TR (TM)
MODIFIED WAVE
INVERTERS
TR: Size 8-1/2
x 7-1/4 x 21"
Mounts to 16" studs on wall
Weight 35 to 45 lbs
XANTREX TR Series Inverters: 1500 watt, 2400 watt, or
3600 watt continuous power plus double surge power for
motor starting. Efficiency is 95% top, and 85% at full
power. The inverters have an internal
thermostat controlled fan to cool only when needed. Certified to UL standard for
National Electric Code. TWO year factory warranty.
(Two identical TR inverters can "stack" for split 120/240 volt output,
but consult us for advice first).
SEARCH MODE
automatic idle means that after last AC lamp or appliance
is shut off. Inverters idle
at 0.17 to 0.35 amps. When you turn on
a light or appliance it starts up again. Start sensitivity is adjustable.
STANDBY BATTERY CHARGER with 30 amp
generator transfer relay is included in all TR models.
When you start the generator, or plug into utility
power, standby feature automatically charges the battery
and switches generator or utility power directly through
for your use while batteries charge. When the generator
or grid power stops, it switches back to use inverter AC
from battery power. Inverters includes temperature probe.
1500 WATT continuous power inverter runs TV, household
lights, computers, stereo, vacuum cleaner and most small appliances all at the
same time. Large loads like washing machine, microwave oven, and circular saw
will run only one at a time, but with many small appliances running too.
2400 WATT continuous power rating. Like 1500, but runs 2 large
appliances at same time. Will run 1/3 and 1/2 horsepower 120 volt AC Grundfos
well pumps.
3600 WATT continuous power rating. Extra margin of power for large
loads and shop tools. Runs well pump and most washing machines together.
Backwoods Solar takes trade-ins of the smaller inverters in our
catalog toward purchase of a new inverter.
SHIPPING any TR series inverter in 48 states $35
Each inverter requires heavy
battery
cables with lug ends.
Note: this battery charger may deliver just 50% or less of rated battery
charge amps if used with a lower quality generator with deficient peak AC
voltage. If you experience this problem, an aftermarket
boost
transformer can restore your generator voltage for full rated charge amps.

MAGNUM ENERGY
The
MM-AE series 12VDC inverter/charger is a modified sine
wave inverter designed to accommodate entertainment
systems and small appliances in smaller RV’s, boats and
cabins. They are versatile, easy-to-use, and
lightweight. Each MM-AE model uses Magnum’s PFC (power
factor corrected) charger, which uses less energy from a
generator than a standard charger - using 25 - 30% less
AC current than standard chargers. 2 year warranty.
Dimensions 16.6” x 8.4” x 4.7”, weights 20 pounds.
Shipping is $35

The RD series inverter/chargers are designed
specifically for off-grid use. The PFC battery charger
efficiently charges your batteries even at low AC
voltage from low-cost generators, which the modified sin
wave inverter keeps the costs down. Additionally the
battery temperature sensor works with the charger for
optimum battery charging. Install the RD Series in four
easy steps: Simply connect the inverter’s output to your
distribution circuits or electrical panel, connect your
power cable (AC) to the inverter’s easy-to-reach
terminal block, connect the batteries, and switch on the
power. Shipping on all RD inverters is $40.
The
ME-RC50 controller is required for inverter programming.
2 year warranty. Dimensions: 13.75” x 12.65” x 8”,
inverters weigh between 38 and 45 pounds.

SMALL
12 VOLT- MODIFIED WAVE INVERTERS
Low cost starter inverters. Backwoods
Solar takes these as trade-in later for larger inverter if needed. All these
feature manual on/Off switch, power LED, and low battery alarm at 10.7 volts.
Shuts down on overload. Fans run continuously, making some noise. Small
inverters can cause more radio and TV static than higher quality inverters.
