15W solar panel and HQRP DID charge battery through absorption layer because float charger is now finishing charge.
Float charger shows 0 mA out and 7W AC in when battery is not fully charged.

Conclusion is that HQRP and Harbor Freight 15W solar panel charged the 12V 35Ah AGM battery.

From actual experience, wind farms produce 1.2 watts per square meter. Solar Thermal and Photovoltaic methods capture 5 to 6 watts per square meter. There is no economy of size in either technology. Dividing the watts you need by those values gives the land area in square meters needed to produce the juice. The numbers are astronomical

got banged while plugged into the 80W inverter. :(

How did they do this ... and are able to sell it for under $20?


finally located in Lenovo G580 box.

Out of warranty by about 11 days. 
Repair attempted.



Which MCU (MicroController Unit)?
Bottom of board.



Cylindrical can above orange capacitors on photo of bottom of abover board likely contains the crystal for the oscillator assembly.

Physical shock can break crystals.

What software technology was used?

Assenbler is a bad choice.

Formatting binary numbers to print as ASCII characters on an LCD is best handled with a small operating system such as BASIC52 or Forth.

I love the product and what it represents. I have since ordered the energy monitor to see what it is doing, but there is an absolute evil satisfaction to see the utility meter stand still during the middle of the day!!!

Focus really is on charging batteries.

Solar panels are used extensively in New Mexico for charging gate opener batteries.

Solar might require a rethink of its applications for electricity use.

Using wires may be a bad idea.

Miners use batteries to power their head lamps.

Futures homes might have a head lamp rack in the front door. Residents put on head lamps.

Batteries solar charged, of course!

Hello HQRP,

Solar charge controller NV12-12V101 purchased through Amazon appears to have a problem.

Power is drawn from the battery instead of the solar panel when green LED slowly blinks indicating the battery is full and there is ample sun.

Problem is fixed by a microcontorller hardware reset. But then recurs.

Here's link to several videos of the problem.

Unit is under warrantly.

Please advise.

Natural Gas on Track to Become Next Energy Giant.




The growing role of the U.S. in world energy markets was underlined on Friday as the Obama administration approved wider exports of liquefied natural gas and international companies committed billions of dollars for new infrastructure.

The developments were both consequences of the shale revolution in the U.S., in which improvements in the techniques of horizontal drilling and hydraulic fracturing, or "fracking," have unlocked new supplies of oil and gas, and raised the prospect that the US will be an increasingly important supplier of energy to the rest of the world. Saturday,

The Obama administration on Thursday issued a new set of proposed rules governing hydraulic fracturing for oil and gas on public lands, moving further to address industry concerns about the costs and reporting burdens of federal regulation.

Sunday April 12, 2013 was a fair solar day.

Sunny in the morning with white clouds in the afternoon.

But meter staring more interesting because the charge/load controller must supply constant load current.

Load current is supplied from the solar panel unless it cannot supply current at which time the battery kicks-in to supply current. Battery current changes from - to + when this occurs.

Charge is applied to the battery when - curent is seen on the batttery current meter. The 2V 35Ah AGM is charged while charging other batteries if the battery current is -.




Results of charging after after about 8 hour.

Over charge is not good but no timer for 9V battery charging, only AAA, AA. C, and D NiCd and NiMH.

9V full charge should be accompanied by 25mA drain. Yup.

Battery 12 rapidly drained as evidenced by the 18..43 mA after a short period.

Free meters set on charge work well to test battery condition.

Start power consumption appears to be problen. not Harbor Freight inverters.

Screaming inverter video. 15:10

Inrush current, input surge current or switch-on surge refers to the maximum, instantaneous input current drawn by an electrical device when first turned on. For example, incandescent light bulbs have high inrush currents until their filaments warm up and their resistance increases. Alternating current electric motors and transformers may draw several times their normal full-load current when first energized, for a few cycles of the input waveform .

An incandescent bulb typically has an inrush current that is typically 12-15 times the amount of the steady state operating current. Thus for a 60 watt bulb that normally draws about 1/2 Amp steady state current, the inrush current is about 7.5A, when using the high end of the multiplier to be conservative.
