120v LED vs CFL vs 12v Lamps Results

I also took a close look at the converter setup. Looks like it shares a 15 amp breaker for receptacles, converter, and the 120v lights in the slide.

My converter looks like this this one:



Has room for more breakers and more 12v circuits.
Have to figure out how to hook up an inverter and what size...

Would MSW give any troubles with computer power supplies or other RV equipment? I could bring an inkjet instead of laser, which would be a wise power usage choice anyways.

Except for electric blankets/heating pads, what else might have trouble with MSW?

I *may* just go with a large whole-coach MSW inverter and just turn off the converter. They are a LOT cheaper, for sure!

Umm.. "computer" power supplies unlike the wives tales spread about on the wobbly web DO NOT NEED PSW..

I HAVE been running IBM compatible PCs since the IBM PC/XT days on UPS units which ARE MSW.. In fact 99.9% of the UPS units you can buy are only offered as MSW.

Computer power supplies don't give a twinky about what kind of waveform that goes into it, you can even feed DC (that is correct DIRECT CURRENT) into them and they WILL operate fine..

Pretty much any switching power supply can support MSW input and live to tell the tale..

The secret as to why is the input actually has a full wave rectifier which converts the in coming AC into DC, then the DC runs through a high frequency chopper (IE switcher) into a small high frequency transformer.. The output of the transformer is the rectified and filtered into DC voltages for the computer..

The only things to be concerned about is the newer electric blankets/heating pads which have electronic controls, some AC motors, clocks that use line frequency to keep time and microwave ovens tend to run slow..

I personally use a Tripplite PV1250 to run my home fridge conversion, that inverter is an industrial built inverter which uses a big heavy 60hz transformer in the output instead of the high frequency chopper of light weight inverters.. It IS designed to be able to handle heavy surges of induction motors..

As a side benefit, the Tripplite PV1250 has a "Load sense" control, when enabled you can adjust the inverter to turn on/off with a AC load..

I have mine set to turn on as low as a 9W incadescent light bulb, allows for the fridge light to turn on the inverter when the door is opened and shuts off the inverter when the door is closed..

Works real slick and you would never know that you were not on shore power..

Saves a lot in battery capacity..

If you want remote on/off, there is a separate remote that can be added to the PV1250 for that purpose..
