I want to cut down some electricity costs by installing a solar setup as my following plan, please recommend me if something is terrible and needs to be rectified. I wish to run all house lightings off solar power. I'm not much interested in the PM solar scheme which connects my solar to grid , and want to have a diy setup.
Panel - Luminous 12V 105W - Rs. 4500/-
Charge Controller - Luminous 12V 20A PWM - Rs. 750/-
Considering solar energy harvested daily 800/900watts, I chose battery as,
Battery 12V 80Ah Exide- Rs. 7000/-
For the DC to AC inverter part, I'd like to utilize an Foxin 600va UPS I have lying (with battery dead).
As per my idea, I have to increase the heatsink or add a 12v fan at the heatsinks of the mosfets of the UPS circuit because those would be hot after prolonged use.
This solar supply line will be fed into my house's all lights. Since all lights are LED tube/ bulbs those should run fine with UPS output voltages (which may not be sine wave) . I don't want to run FAN/TV or other heavy loads and overload my small solar setup.
This would require me to hire an electrician for connecting solar AC supply to all switch boards and connect the lights' switches to that supply line. This thing I'm not confident to do myself because only god and electricians know which concealed pipe goes to where .![Stick Out Tongue :p :p](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Considering 3/4 tubelights , terrace lights, gate lights, kitchen, bathroom lights, etc ,whose combined wattage is around 150W my battery may supply enough power for the evening to night times..
Now I have to make a changeover circuit by using relay for when UPS output drops, the solar supplied AC line would be connected to mains AC line.
