Modified Wave Inverters

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: 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.

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.

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.

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.
