    Switching the UPS input from Electricity to Solar Panels

    Hi ,
    I have UPS Invertor for 700 watts that takes electricity from input and charge the battery and auto switch the rooms to that battery.
    I want to buy 150 watt solar panel.
    I want to switch that input to solar panel in such a way that i can directly use the electricity generated by the solar panel and charge the battery also.

    I want to do it my own .Using that UPS invertor of 700 watt by switching the input from electricity to 150 watt solar panel rather then buying new controller instead of it
    How i can do that

      Truthfully, a 150w panel is not going to do much to power a 700w UPS. 2 days of full sun, will harvest barely enough power to run the unit for half an hour.

      Generally, UPS has a GEL battery which needs to be trickle charged, and solar charging it quickly, will damage a GEL battery.

      And any large solar panel connected to a battery, needs a solar charge controller

          Thank you.
          It there any way same battery can be connected by solar panel controller and with the UPS electricity input. So i can turn off the electricity input when solar charging is ON.

              You will not be able to use the DC voltage output of a solar panel to directly charge the battery in the UPS. A UPS charging system is very unique to the installed battery. The UPS design is usually accepting AC voltage and converting it to the correct DC voltage to charge specifically that battery chemistry. Most solar charge controllers are not designed to provide the DC voltage for a UPS battery.

              The only safe way to use a solar panel to charge that UPS battery would be to have a separate system (solar panel, solar charger controller, battery and DC to AC inverter) to produce the AC power the UPS is looking for. This is an expensive way to recharge the UPS battery. It would be cheaper to just use a small generator to provide the AC voltage the UPS is looking for.
