Solar installed, but the power still went out? Here is why

You installed solar, the sun is shining, and KSEB's supply failed. Your lights went out anyway. Almost every new on-grid customer calls us about this once, so here is the honest explanation.

Why on-grid systems switch off in a power cut

Grid-tied inverters are required to shut down the moment grid supply fails. The feature is called anti-islanding, and it exists to protect the KSEB lineman working on the line that your roof would otherwise be feeding. Every certified inverter in the country behaves this way. It is a safety standard, not a defect.

Your options if power cuts matter to you

A hybrid system adds a battery so essential loads keep running while the grid is down, and still exports excess power to KSEB on normal days. A full off-grid system removes the grid from the picture entirely. Both add battery cost, and batteries need replacement every 5 to 6 years, so the right answer depends on how often your area actually loses power.

In our surveys we ask exactly this question about your locality before recommending a system type. If outages in your area are rare, paying for batteries to cover them is money better left in your pocket.
