SOURCE: Trace inverter high AC voltage

Not to worry. First thing is you are probably not using a true RMS volt meter. You are reading an average voltage of peak. You have a sine wave inverter. The RV 2012 has a peak of 164 volts. I could go into much more tech detail but may confuse you. If you want to learn more her is a link from my dealer tech sheets. Also if you have checked voltage in a float state it will read high.

Hope this helps you

Thank you for using Fixya and please rate us.

SOURCE: Low voltage output from inverter

Ignore peak, that means nothing. RMS * 1.414 = peak. RMS is the actual usage you will get, thats all. Peak doesnt mean it will supply the peak wattage for a short period of time: salesmen with no electrionics training tell people this and its a big fat lie.

See what the unit is drawing, use a clamp-on ammeter on ONE lead (not both, or it will read 0). That shoudl tell you if your device is drawing too much. You should only be able to run that device UNDER the 800 Watts (watts = volts * amps, not including loss of efficiency which might be 10% or more, and even greater when warm)

SOURCE: Trace DR 2412 inverter won't run older front-loading washer

IF your washing machine is a conventional model with a common AC induction motor, waveform isn't the problem. Normal starting current for typical AC induction motors is usually 5 to 7 times the rated running current. Even though that current draw only lasts a fraction of a second, it's marginal for a 2.4 kw inverter's surge capacity. The trick of switching on other small loads (preferably resistive loads like incandescent bulbs) before starting the washer may help. Another area to check is your battery cables and connections The inverter pulls a huge amount of current to produce it's max surge output and even a little resistance in the battery circuit may cause the inverter to trip off. If you've got one of the fancy new electronic controlled washers with a D.C. motor, (so called energy saving or high efficiency models) then the waveform may be an issue and a pure sine wave might be needed.

SOURCE: new batteries new cables still 99 volts output

What kind of inverter is it and what kind of meter are you using to check the voltage with? If the inverter puts out modified sine wave, you have to use a true rms volt meter to accurately check the voltage with. A non rms volt meter will show a low reading.

SOURCE: I have 2 DR 15/24's,

hello,

here is the pdf manual for your inverter,, it will walk you thru the equalization process of your system. www.donrowe.com/user_guides/xantrex/trace_series...

the equalization information is on page '2-14'

if you are still having troubles you can write me back here and I will walk you thru the process.

you can also visit the xantrex web site at : www.xantrex.com.

have a great day,

Check your parameters for charge voltage and battery type.

Is your 12 volt source able to supply 1500 watts of power?
You can't draw more watts out than you put in. What is your 12volt source? A standard automotive alternator cannot make close to 1500 watts.

try adjusting the gen voltage at no load to run at 240 volts

when the load comes on it will drop back to 220-235 volts

check the load output from the inverter as 2.5 kv is nearly 80% of the genset duty cycle

4.5 KV is start up KV and the duty KV is around 3..8 kv not the plated 4.5 kv

to get constant 4.5 kv you will need a 5.5-6 kv unit

if the current draw from the inverter is excessive , the engine may not have enough in reserve to over come the load and will not pick up the rpms

take the gen set and the inverter to a shop that has a calibrated load bank to test accurate power output to determine if the engine needs an overhaul

when the load comes on it will drop back to 220-235 volts

I have a trace sw 4048UPV 240v I would like to know if i can do split phase 120v/240v? what I will need?

Most low voltage conditions on generators are simply due to a low engine rpm. Most modern generators are 2- pole windings. So your engine rpm should theoretically run @ 3600 rpm. which will produce 120/240 volts @ 60 HZ. In actuality You want to set your rpm's @ Approx. 3720rpm no load. About 62.5 Hz. Without getting to technical this will give you your desired 120/240 volts loaded. Hope this helps.

The rms voltage is what counts, because it tells how much power the output will deliver to a resistive load. Inexpensive multimeters on their AC ranges are usually average-responding rms-calibrated meters. This means they measure the average of the absolute value of the AC component of the signal, and display that average multiplied by about 1.11 (actually, pi over sqrt(8)), the ratio of rms to average value for a pure sine wave. That way, the meter will give the right rms reading for a sine wave.

If the signal is a square wave, where the average and rms values are equal, the average-responding meter will read 11% too high.

Many inverters put out a modified sine wave (MSW), which sits at zero for a while, goes to a constant positive level for a while, goes back to zero for a while, and goes to a constant negative level for a while to complete the cycle. The positive and negative parts of the signal have the same magnitude and duration.

The rms and average values of an MSW depend on its duty cycle D, the fraction of a cycle for which the signal is not at zero. In a well-designed inverter, the duty cycle will be adjusted when the DC input voltage goes up and down to maintain the nominal rms output voltage. If we use peak voltage Vp to mean the magnitude of the positive and negative voltages the signal goes to, then Vavg for an MSW is equal to Vp times D, and Vrms is equal to Vp times the square root of D.

The duty cycle for which an MSW will have the same rms to average ratio as a sine wave is 8 over pi squared, or 81%. For any duty cycle less than this, an average-responding meter will read a lower voltage than the inverter rms output, and for a duty cycle higher than this, the meter will read too high.

If your MSW inverter is putting out 120 volts rms and its duty cycle varies from 50% to 75%, the meter reading will vary from 94 volts to 115 volts. I avoid the problem by using a Radio Shack 22-174B true rms digital multimeter.

Your inverter has a peak of 3000 watts rating and should power that hair dryer. Make sure your batteries are in good shape. The inverter can only put out what it takes in. 1800 watt demand on the inverter requires 1800 watts from the batteries.
