Voltage report using a Sola Basic autoformer
Hi,
First test of a Sola Basic autoformer on August 5th, 2016 starting at 2:30 p.m.
The unit cost was $232.50 Canadian dollars. I added a #10 shore power cord, a 30 amp RV outlet, a 15 amp female outlet, and a 15 amp female outlet in parallel to the 30 amp cord. That is so I can easily monitor whether it is doing anything to the voltage or not.
I added several holes to allow for cooling, but it appears that may not have been necessary.
I can report that the Sola Basic autoformer works well with shore power.
The fridge was running on electric for this test and wattage was 1630.
On a thirty amp shore power supply, before the air conditioner was started voltage was 115. Without the autoformer it dropped to 105, when air was turned on.
With the autoformer in the circuit voltage actually rose instantly from 115 to 118.
After one hour I "shot" the temperature of the case and found it was 27 C (ambient). I then "shot" through one of the cooling holes at the transformer. Temperature was 26.8 C.
I just, as a test, added the water heater. Wattage jumped to 2995, input voltage at the Sola Basic dropped to 104.5, and voltage inside the RV dropped to 109.5 (113 at the output of the sola basic). I turned off the water heater within 3 minutes.
The air just cycled off, and wattage dropped to 321, voltage inside rv at 114.
Air cycled back on, and wattage is 1672, voltage inside RV at 118.
The equipment was 60 feet of #10 cord into a 30 amp outlet, the solar basic feeding the Magnum 3012 hybrid inverter (load support mode turned off), and the RV being fed from the Magnum.
I'll be testing with various other power sources, such as 15 amp and generator, though I don't think I'll be able to notice anything with the generator.
I'm sold!
