Computer Speakers (4.1 Surround Speakers) 15 Watts
(being a music lover I better love speakers which are big and can produce excellent sound quality)
Laptop 35-90 Watts
(on a full charge it consumes just 35Watts but when its battery is getting charge it should consume 90Watts)
Wi-Fi Router+Wired Switch+DSL Router 10 - 15 Watts
External TV Tuner 6 Watts
(whether I turn on or off, anyway its power-adapter is on, so its the "phantom power" which is sucking power)
Total Usage: 66 - 126 Watts
UPS Load when there is power: 66 - 126 Watts
UPS Load when there is no power: 36 Watts (since laptop works on its battery)
Unfortunately I have not found any ready-made commercial solution which can specifically address this energy requirement. Either the solution is too expensive and far bigger than what is required or simply the small scale solutions which are not flexible enough if I want to upgrade or scale-up in future. So I thought let me design a clean energy solution myself.
Overall Setup before connected to Non-Renewable Power Source.
Step 1: Overall Setup After Connected to Clean Renewable Power Source
Step 2: 1000W - 12V DC to 220V AC Car Inverter
1000Watts 12V DC to 220V AC Converter Inverter
- whole kit contains
- Inverter box
- Connector wires with battery clips
- Connector wire with Car Cigarette Lighter Port
- Power socket converter
- Instruction Manual
Step 3: 12V Old Rescued UPS Battery
Step 4: 12V, 10Watts X2 Solar Panels
- 2x 12Volt 10Watt Solar Panels
- Set of Battery Clips + connecting wires
- Blocking Diodes (31DF4)
Step 5: Soldering Wires to Solar Panels
Step 6: Finishing the Jig-saw Puzzle.
Step 7: Powering-up
Step 8: Panels Basking Under the Sun
Step 9: Closing Note
***Check the next step and find out how this current setup have been upgraded after 3 weeks with additional 74Watts Solar panel, hence with the total solar power production capacity of 94Watts.
You can find much more exciting projects from my Traffic Squeezer Website - Go-Green section.
Step 10: Upgradng a 74Watts Solar Panel
So with the total power production of 94Watts is just self sufficient to power-up the load which can consume anywhere around 66-126Watts. If the power production goes up beyond the usage in that case an extra battery can be added to store that additional juice. Which can be used for other purposes too. Since currently the load is much more than the power production and even the battery capacity, I have not got yet any charge controller device/circuit. But getting a simple charge controller to charge the batteries is quite suggested since it should improve the overall battery life.
