Hi, just got the 13 watt briefcase solar charger. The blue light is blinking, but my phone shows no charging action. What am I doing wrong

Passive solar energy can be used to keep buildings warm. Some buildings have large windows on the side of the building the sun hits. The sun's ray go through the windows and penetrate the heat-absorbent floors and walls. At night, this heat is released into the building.

Not using enough solar panels or total output to match the needs for what you would be using it for. Small solar panels (35-100 watt) are great just to keep 1-4 batteries charged when not in use but if you plan to be running an inverter and powering appliances, living quarters in an RV or larger scale living, that if when you would need A LOT of solar panel and a basement full of batteries to use at all times. A lot of money would be spent on the panels and batteries but if you do not have the right equipment to control the electricity and monitor everything, you may be better if donating the money to a good charity where it will be much more useful and greatly appreciated

If you have too much weight from wider blade, check to make sure there is not too much pressure on the bearings to operate properly.

The space industry was one of the first industries to adopt the use of solar energy. It started using solar technology on spacecraft in the 1960's.

Pressure Control Solenoid Malfunction.
Possible cause:
* Low transmission fluid
* Dirty transmission fluid
* Faulty line pressure solenoid valve
* Line pressure solenoid valve harness is open or shorted
* Line pressure solenoid valve circuit poor electrical connection

That should help get you started to figure out what may be your specific issue.

First thing, disconnect AC and DC power. You can leave the LP attached but go ahead and close the valve for now.

Plug in AC only and let it boot up. If the fridge does not automatically, press the power button to turn it on. The refrigerator should start working. Let it run for a while to make sure it does get cold. Once you confirm it does work you can either unplug the fridge or just open the breaker in the fuse panel.

Before you reconnect the DC wires, you need to check the power coming in. Most camper units will have wiring that will have color on one side and white on the other. The color wire will be your 12VDC, white is neutral return. Once verified, pull out the fuse for the power to the fridge to isolate the DC voltage. Check with the manual for the fridge, the positive input should be marked or identified in some manner. Open the valve to let LP back into the lines and wait a few minutes. Plug the fuse back in. If the fridge does not turn on automatically, press the power button to turn it on.

With the DC power on and no AC detected, the display should display CHECK. Let the fridge run for a bit to make sure it cools. Once you know it is working, the breaker for the AC can be closed to turn on the AC power to the fridge. Press the MODE button until AUTO displays displays.

Let it get cold and resume normal operations.

Solar energy is the output from our sun though not strictly correct it is sufficient for most purposes to say it is the sun's energy that reaches Earth. It includes a wide spectrum of different frequencies/temperatures of light and energy and various types of particle and electromagnetic radiation, a significant proportion of much of the content is deflected by the Earth's magnetic field and various layers of the atmosphere.

The solar energy reaching the Earth's surface is reckoned to average the warming equivalent of 3kW/hr per square metre.

Photovoltaic (PV) is a process that converts the Sun's heat/light into electricity and should not be confused with the Solar/thermal systems designed to use the sun's heat/light radiation to heat water. Mostly this is used for domestic purposes but some large installations exist where large mirrors concentrate light onto a solar panel with enough heat to produce sufficient steam to drive a turbine/generator to produce electricity.

Photosynthesis, incidentally, is the method plants use to convert atmospheric CO2 into growth using energy from the sun.

Always take pictures first before you fix
anything, or take it apart. so you will know how to put things back

With so few panels, you could use microinverters in parallel instead of series, such as from Enphase

But if you want to stick with series, then a 1.2 kw string inverter is what to look for. Perhaps something like these
