Although the IPS was bought about 6 years ago, an engineer checked and said it is in good condition. I have installed solar power, so I don't need this anymore. It will provide good service for 2 fans and 3 lights, Insha'Allah. You can add more lights and 1 fan if you want, but it's better not to add more for good backup power. There is no battery, I am saying this beforehand. Just the machine. You can come and check it before taking it. It would be even better if you bring an engineer who understands well with you.
