With many unanswered questions about what a Solargizer really puts out, I ran some tests. I used a smallish 15AH 24v battery to test with (needing to set up close to power for the O'scope). (used Concorde aircraft battery, RG-24-15).
The Solargizer is model 735X150 IS24L, an Ebay purchase.
With full winter sun, the Solargizer was pulsing every 20 microseconds with a 1 microsecond pulse-width pulse, and peak to peak voltage of about 1 volt. The pulse was actually about 0.8 v above battery voltage, and the tail of the pulse depressed the battery voltage by 0.2 volts. Looks like the Solargizer draws current from the battery for roughly 1/5 of the cycle, adding energy from the pulse for 4/5 of the cycle.
Note the ratio of pulse width to pulse rate, 1/20 th of the cycle. So it actually charges about 1/20th of the time it's hooked up.
So, how much does it charge? In order to measure the current, I put a resistor decade box in series and used the 'scope to measure the voltage across the resistance. 50 Ohms yielded 5 v P-P. Current is voltage divided by resistance, about 0.1 amp, and Watts calculate as 0.1W.
Remembering that these small charges are only being applied 1/20 of the time!
This test certainly shows why there is no claim for a Solargizer actually charging a battery!!! But, there's no doubt those pulses do the job they are intended to do, as many users will testify.
Another question had been asked: will the solargizer hurt itself with no battery attached: No, with no battery attached the Solargizer is not powered.
I was curious about using a 24 v Solargizer on a 12 v battery. Yes, works fine. Pulse rate and P-P voltage of the pulses changes but the pulses are there.
Another test: Would the Solargizer put noticable charge into a small battery? I used a little 12v gell cell rated at a few AH. Yes, the Solargizer is able to actually raise the voltage on this battery. Starting at about 12.5 volts, in an hour the float voltage was up to 13.2, then the sun dropped too much to continue the test. If a Solargizer were hooked to a small battery and left full time, it might conceivably over charge it.
There was nothing scientific about this test and the Solargizer people might have better info, but this is more than I knew before.
