About this deal

I have attached to SMD ,12v 10 watt, cap 1000uf,16 volt and a bridge rectifier you can see the part number on that.When I turn the lights on the rectifier starts to heat up and the both SMDs as well. I am afraid if these lights are left on for a long time it may damage the SMDs and rectifier. I don not know where the problem is. You may help me. Also since the inverter needs a battery to operate which can be assumed to be a 12 V battery, all the parameters essential for the set up may be calculated in the following manner: The seventh solar charger discussed here is best suited as a solar LED street light system is specifically designed for the new hobbyist who can build it simply by referring to the pictorial schematic presented here. When you plug the unit into a wall outlet, a green light indicates the USB port is ready to use. You can then plug in a USB cable to charge a smartphone or other device. This port is a convenient extra feature that lets the charger double as a USB wall plug, but note it will not charge batteries while the USB port is in use. You also can't unplug it from the wall and use your batteries as a portable power bank to charge other devices on the go.

With regards to the solar car battery charger, you can charge the battery from inside your car. Just plug it in to the OBD connector and let it sit there. How To Find Your EOBD Connector The DC input source is a solar panel which may be capable of producing an excess of 3V during optimal sunlight, and allow the charger to charge the battery with a maximum of 1.8V output. It automatically detects the type and capacity of each battery you put in and selects the optimal current. You can also fine-tune the settings manually, such as choosing a current as high as 3A (amperes) for faster charging. You can then monitor detailed information like the battery status and time on the high-definition LCD screen. I would like to switch them off during bedtime, though.3. My current lighting system (which I wish to illuminate) consists of two regular bright light Tube lights ( 36W/880 8000K ) and four 8W CFLs. P1 is used for adjusting the T1/T2 stage such that the T2 LED just illuminates at 12V, similarly P2 is adjusted to make the T4 LED begin illuminating at voltages below 11V.

A simple solar panel voltage regulator circuit may be witnessed in the following diagram, the given switch may be used for selecting a battery charging option or directly driving the inverter through the panel. The solar LED circuit is capable squeezing out the last drop of "joule" or the charge from the cell and hence the name joule thief, which also implies that the LED would keep illuminated until there's virtually nothing left inside the cell. However the cell here being a rechargeable type is not recommended to be discharged below 1V. As a bonus, the SC4 offers USB output, so you can connect devices like a phone or laptop after your batteries are done. You can also buy it in a bundle with a battery case and a car adapter. In our range below of solar battery chargers, the solar panels are integrated with a battery holder and appropriate circuitry, so all you have to do is pop in the batteries and leave the charger in the sun. Most of our chargers are for AA or AAA batteries, but the kit that includes the Digivario will also take many camera batteries.

Next, using a variable power supply, apply a precise 13V to this T1, T2 stage, and adjust P1 such that the LED just illuminates, increase the supply a bit to say 13.5V and the LED should shut off. This test will confirm the correct working of this low voltage indicator stage. Whether you want to build your own home theater or just learn more about TVs, displays, projectors, and more, we've got you covered. But thanks to the modern highly versatile chips like the LM 338 and LM 317, which can handle the above situations very effectively, making the charging process of all rechargeable batteries through a solar panel very safe and desirable. It's usually easy to see how many slots a battery charger has. Many can hold four batteries, though others can fit eight, 16, or more. Chargers that support larger battery sizes may take up two of those slots. You'll also find that inexpensive chargers often require charging batteries in pairs and that charging more at once usually means longer charge times. For example, if the open circuit voltage of your solar panel is 20V and the battery to be charged is rated at 12V, and if you connect the two directly would cause the panel voltage to drop to the battery voltage, which would make things too inefficient.Using the link below, you can search your cars manufacturer and model and be able to plug in to your connector. However practically the above conditions could be difficult to achieve because solar panels never produce constant outputs, and tend to generate deteriorating power levels in response to varying sun ray positions. The 'THINFILM' technology allows a wider spectrum of natural light to be absorbed, meaning the unit can still generate electricity under cloudy winter conditions. This technology also enables the solar panel to handle the intense heat of the summer sun with little power loss due to the rising temperature.

Points were also awarded for ease of connection, features such as USB outlets, and overall value. Solar: Plan ahead The emitter follower also makes sure that the battery is never allowed to get overcharged above the allocated charging limit. The arrow symbol shown connected with the panel voltage positive can be replaced with a rotary switched for the recommended selection of the diodes in series.The drop of 0.7 V across each diodes raises the grounding threshold of the IC by stipulated level forcing the IC to regulate the output at 14.1 V instead of 12 V. The 2k2 resistor is used to activate or bias the diodes so that it can conduct and enforce the intended 2.1 V total drop. Making it Even Simpler The two LM 338 stages are configured in standard current regulator modes with using the respective current sensing resistances for ensuring a current controlled output for the relevant connected load. The IC2 stage can be built as shown and will not require any setting up procedure except the selection of R11 which may be done using the formula as expressed in this universal current limiter article Parts List The AA Solar Battery Charger is suitable for Car and Caravan + many other 12v batteries (Motorhome, Motorbike, Golf Buggy, Electric Fence etc..)
