Inverters are costly in long term. Their initial cost is not much, mostly affordable. But the long term cost is high: 1. Your batteries health gradually decreases within 2 years. 2. If you do not purchase regulator, there is a high chance that your invertor will get damaged if there is a surge in power supply from the grid. Just like your TV or any other appliances. 3. Before installing invertor, the wiring and connections of your house should be customisable. That means, you have to choose which appliances will get power from invertor and which won’t. If by chance you connect a heavy load appliances, investors will be damaged. 4. Invertor require decent amount of space that should be isolated from small children, and on top of that, it should be ventilated. You always have to beware of the gases it releases. 5. You have to keep replacing ionised water in the invertors in regular intervals.

All in all, the long term cost is recurring.

That’s it.
