Powersource-1800

After reading about the Powersource 1500 for $149 at Tractor Supply, I called the local TSC store and asked. No, they did not have one nor did any store in a 100 mile radius of where I live. They DID have an 1800W unit in one store 90 miles off. It was $199 +tax.

I asked them to put my name on it. Friday evening I traveled through the countryside  and picked it up. After a day of charging, I tested the unit. It switched fine and has a display informing one of the power it is supplying.

The unit 'passes through' normal AC and when the power goes off, it comes on very quickly. The Ocilliscope shows the output to be 'modified sine wave'.

It has 3 X 17AH 12V batteries for '60AH battery'. I'm guessing it will really supply about 300Wh without killing the batteries rather rapidly.

My brother has a place 'in the country' and needed such a backup unit. It now resides with him.

Hi,

As it is Modified Sine and not Sine I would be curious to know if it also runs the fridge. Been told the motors hum louder and may get hot, besides, they may not even start as they are an inductive load and starting amps are up to eight- or more times the running amps.

Is it running the TV or PC? It will definitely run the lights.

Regards,

You can make up a supply with out too much trouble from 24 volt dc ( two 12 volt batteries )from there you have just cut into the 110 section of a computer supply and patch in the voltage for each regulated source .Get an old 400watt supply or two and play with it.

I didn't try in on the frig and don't have a TV (don't need a box that makes one more stupid than natural). It does fine on the computer.

If I care to run a computer off battery power I will probably use a DC power-supply from mini-box.com .

I eventually planning a 48V system and am working slowly toward it.

When the batteries go bad, it'll be cheaper to ditch it. I downloaded the pdf spec sheet. It uses three 1/2 U1 sealed batteries. The batteries are about $50 each.

Make sure you don't leave the batteries discharged. SLA's like that sulfate quickly. They are made to float charge, hard discharge for a short time and then recover on a slow charge overnight.
